Real estate, made simple.

Calculating the return on a property investment involves more than simply dividing the annual rent by the purchase price.

The gross yield provides an initial indicator, but to assess an opportunity properly, acquisition costs, any works, charges, taxation, the risk of rental voids and financing must also be taken into account.

At J&J Invest, we also place considerable importance on the return on the equity actually invested. Borrowing can create leverage and significantly alter an investment’s performance.

For a property you already own, it is also useful to calculate its current yield, based on its present market value rather than its historic purchase price. A property purchased for €200,000 15 years ago and now worth €400,000 should be analysed as €400,000 of capital tied up in your portfolio. Continuing to calculate its return solely on the €200,000 invested at the time may give the impression of an excellent return, when that capital could potentially be used more effectively in another investment.

This approach allows you to regularly ask the right question: if I had the current value of this property in cash today, would I still choose to invest it in this same asset?

Lastly, we always consider the project as a whole: rental income, gradual repayment of the borrowed capital, potential for the property to increase in value and the exit strategy.

It is the combination of these various factors that determines whether an investment is genuinely performing well and remains consistent with your wealth-management objectives.

The period from spring to autumn is generally the most favourable time to sell a property.

Longer days, more natural light and better weather help to showcase properties, particularly those with a garden, terrace or attractive outdoor spaces. Buyers are also generally more active during this period, with more viewings taking place.

However, this does not mean that you necessarily need to wait until spring to sell. A well-presented property that is priced and marketed correctly can find a buyer throughout the year. Winter may even offer certain advantages, including fewer competing properties on the market.

Ultimately, the type of property, its location, its price and the quality of its presentation often have a greater influence than the season itself.

At J&J Properties, we therefore work with you to determine the best time to launch the marketing campaign, based on your property, the market and your personal circumstances.

To enable us to assess your application, we ask only for the information and documents required to evaluate your file, in accordance with the applicable regulations.

In practice, it is generally useful to prepare:

• proof of identity;
• your contact details and the necessary information regarding the prospective occupants;
• supporting documents demonstrating that your financial resources will enable you to pay the rent to the landlord on time;
• where available, rental references, such as a certificate from a previous landlord.

Depending on your circumstances, additional supporting documents may be requested, but only where they are relevant to assessing your application.

The landlord or agency may not request just any information. The data collected must be relevant and proportionate to the intended purpose, particularly to verify your identity and ensure that your financial resources are sufficient in relation to the amount of rent.

A complete application enables our team to assess your application more quickly and, where it meets the criteria, present it to the landlord under the best possible conditions.

The cost of works should ideally be estimated before making a commitment, as it can have a significant impact on an investment’s overall profitability.

At J&J Invest, we prepare an initial estimate based on the plans, a viewing of the property and the type of renovation envisaged. Depending on the project, this estimate may be based in particular on prices per m² drawn from our experience of comparable renovations.

For larger projects or where greater precision is required, we can refine this estimate using comparative quotations and draw on our network of architects and tradespeople to obtain a more detailed cost estimate quickly.

We then include the works budget, together with a reasonable contingency allowance, in the project’s overall analysis.

The aim is to obtain the most realistic possible picture of the transaction’s total cost before purchase and to verify that it is consistent with the property’s value after renovation, the expected rents and the target return.

In Belgium, our profession is regulated by the IPI (Professional Institute of Estate Agents). The standard set by the IPI is 3% plus VAT of the final sale price.
Nevertheless, each agency remains free to set its own rates according to the quality of the services provided. At J&J, our fees vary depending on several factors, such as the price of the property, the type of contract selected, etc.  For complete transparency, we have developed a simple tool on our website that allows you to calculate the fees applicable to your situation in just two clicks. You can find the calculator here.

In accordance with standard practice in Belgium, these fees are usually payable by the seller.
 

Our aim is to present the landlord with reliable applicants whose financial circumstances are compatible with the rent requested.

We therefore assess each application as a whole: the level and regularity of income, employment situation, financial stability, household composition and whether the available income is consistent with the amount of rent.

We also check the necessary supporting documents to ensure that the application is complete and that the information provided can be verified.

Everyone is welcome, provided that their application offers sufficient guarantees and the property is suitable for the number of people wishing to live there. Depending on the circumstances, additional guarantees may also be offered.

Beyond the figures, we attach importance to the overall quality and credibility of the application.

J&J Properties carries out this initial assessment and presents the landlord with applications that meet the property's criteria. The final choice of tenant always rests with the landlord.

No. You do not need to have obtained final approval from the bank before starting to work with J&J Invest.

We can begin by defining your strategy, analysing your objectives and exploring the various investment opportunities.

However, before launching an active search, it is strongly advisable to have at least a mortgage agreement in principle or an initial assessment of your borrowing capacity. This allows us to define a realistic investment budget, focus our search effectively and respond much more quickly when a good opportunity arises. A well-prepared financial application can also reassure the seller when you make an offer.

Your own funds, borrowing capacity and financing terms are an integral part of our analysis, as they can have a significant impact on the project's profitability.

The property search and financing arrangements can therefore progress in parallel, with one objective: to be ready to act quickly when an opportunity matching your strategy arises.

Our fees cover our full range of services, from preparing the sale through to signing the final deed.

This includes the property valuation and definition of the marketing strategy, preparation and management of the administrative file, preparation of the listing, professional photography, a virtual tour and, where appropriate, video and virtual home staging.

We then handle marketing the property across the various channels, managing enquiries, arranging and conducting viewings, and following up with prospective buyers.

When an offer is made, we assist you with assessing it, verifying the prospective buyer’s financial standing, negotiating and managing the transaction through to the preliminary sale agreement and then the final deed, in coordination with the notaries and the various parties.

Our fees therefore cover far more than publishing a listing: they include all the commercial, administrative and personal work required to showcase your property, safeguard the transaction and protect your interests as effectively as possible throughout the sale.

Most importantly, we are paid based on results: our sales fees are only payable if the sale is successfully completed. Our interests are therefore directly aligned with yours.

To find out the exact amount of our fees for your property, you can use the calculator available on the ‘Sell’ page. In just a few clicks, you will receive a clear estimate of the cost of our services.

The length of the tenancy agreement and the notice periods depend on the type of contract, the Region in which the property is located and the party wishing to terminate the tenancy.

For a principal residence, the 9-year tenancy remains the standard arrangement. Short-term tenancies are also available, generally entered into for a period of 3 years or less, along with other forms of tenancy suited to specific situations.

Termination options and notice periods vary depending on the type of tenancy and when the contract is terminated. The rules are not necessarily the same for tenants and landlords either. In some cases, compensation may be payable in addition to the notice period.

At J&J Properties, the duration of the tenancy is clearly stated before it is signed, along with the main conditions that apply in the event of termination.

If you are already a tenant in a property managed by J&J and wish to leave your home, we recommend contacting your property manager before giving notice. We can review the conditions set out in your tenancy agreement and the regulations applicable to your situation with you.

No. Everything is clear from the outset.

We charge only the commission agreed in the sales mandate, together with the statutory VAT. No hidden fees or unexpected supplements are added to our charges during the marketing process.

Any costs relating to the mandatory documents required for the sale, such as the EPC certificate or electrical inspection, remain separate from our fees and are clearly identified when required.

You therefore know from the outset how much our service will cost. You can also calculate our fees precisely using the calculator available on our ‘Sell’ page.

The language of the tenancy agreement primarily depends on the Region in which the property is located and the language used between the parties.

In Wallonia, the tenancy agreements we prepare are generally drawn up in French.

In Brussels, the tenancy agreement may be drawn up in French or Dutch, depending on the language agreed between the landlord and tenant.

At J&J Properties, we generally provide the tenancy agreement in French for our French-speaking clients and can arrange a Dutch version when required.

We also regularly work with international clients. Our teams can therefore provide guidance and explain the contents of the tenancy agreement in English, even where the official contract is drawn up in French or Dutch.

Yes. Through our J&J Invest service, we offer a genuine property search service tailored to your investment strategy.

We begin by defining your criteria together: budget and available equity, financing capacity, preferred areas, type of property, target return, investment horizon and wealth-management objectives.

On this basis, we actively search for opportunities that match your profile, from studios and flats to investment properties and property portfolios.

We source properties across all property portals, as well as through our network of agencies and property professionals. Thanks to J&J’s various activities and our daily presence in the market, we may also gain access to certain opportunities before or outside their conventional marketing process.

When a suitable property becomes available, we alert you promptly and analyse the opportunity with you: price, rental potential, any required works, financing and profitability.

The aim is not simply to find an available property, but to find the investment that genuinely matches your strategy.

Your property is advertised on Belgium's leading property portals, including Immoweb, Zimmo and Immovlan, as well as on the J&J Properties website and our various social media channels.

This multi-channel approach gives your property substantial visibility among prospective buyers, but our work is not simply about advertising on as many platforms as possible.

Every listing is carefully prepared to maximise its impact: professional photographs, a virtual tour, a video where appropriate, floor plans and a detailed presentation of the property. We also refine the titles, descriptions and keywords used to optimise the visibility and search ranking of online listings.

We also draw on our own network. Through our database of prospective buyers and investors, we can directly contact people whose search criteria match your property.

Depending on the type of property and target audience, we can also enhance the marketing through our social media channels, including Facebook, Instagram and LinkedIn, as well as targeted digital campaigns.

The aim is therefore not simply to be present everywhere, but to give your property the best possible exposure among the right prospective buyers.

This mainly depends on local demand, the condition of the property and the asking rent.

A well-presented flat that is priced correctly can find a tenant quickly. In practice, from the time the listing is published, it generally takes between 2 and 6 weeks to complete a letting. For certain particularly sought-after properties, this timeframe may be even shorter.

However, our aim is not to let as quickly as possible at any price or to just any applicant. We seek the right balance between the rent level, speed of letting and quality of the tenant.

We therefore optimise the marketing, publication of the listing and organisation of viewings to minimise rental voids as far as possible, while ensuring that applicants are carefully vetted.

With more than 200 lettings completed each year, our teams have practical knowledge of the rental market, enabling them to position your property effectively as soon as it is offered to let.

Absolutely. Our support does not end with the acquisition of the property.

Through our Optimiser service, we can coordinate the necessary works, from straightforward refurbishment to major renovation. We assist you in defining the project, setting the budget, selecting contractors, and coordinating and monitoring the works.

Through our network of reliable contractors, architects and tradespeople, we can centralise the various stages of the project and monitor progress, costs and the proper completion of the works.

You naturally retain decision-making authority: the budget and major works are approved with you before they are carried out.

Our support can then continue with letting and managing the property. The aim is to assist you throughout the entire investment cycle, from purchase through to operation.

Yes. The way a property is presented can have a significant impact on the interest it generates among buyers.

Before putting the property on the market, we advise you on improvements that can genuinely enhance its appeal: decluttering, staging, furniture arrangement, garden maintenance, fresh paint, minor repairs or rectifying certain visible defects.

Where appropriate, we can also arrange light home staging before the photographs are taken, thanks to our network of specialist partners.

We can also use virtual home staging. Photo editing and artificial intelligence tools can, for example, be used to declutter a room virtually, remove certain items of furniture or personal belongings, replace existing furniture or virtually furnish an empty property. This allows prospective buyers to better imagine themselves in the property and reveals the potential of a space without necessarily carrying out work or moving all the furniture.

We then pay particular attention to the property's marketing presentation. A well-presented, carefully staged and professionally photographed interior creates a stronger first impression and attracts more prospective buyers.

The aim is not to have you undertake costly work before selling, but to identify the physical or virtual improvements that can genuinely enhance the property's value and make it easier to market.

You can move in from the possession date stated in your tenancy agreement, provided that the various preliminary formalities have been completed.

Before the keys are handed over, the following must be in order:

• the tenancy agreement must be signed;
• the rental deposit must be in place;
• the first month's rent must be paid;
• tenant insurance must have been taken out and proof must have been provided to us;
• the check-in inventory must have been completed.

We will arrange an appointment with you to complete the check-in inventory and organise the handover of the keys.

Once these formalities have been completed, you can take possession of the property on the date specified in your agreement.

A property sale generally takes place in three main stages. At J&J Properties, we support you and coordinate the entire process, from the valuation through to the signing of the authentic deed.

1. Preparing the sale

Before marketing begins, we value your property, define the sales strategy with you and compile the necessary documentation: agency agreement, EPC certificate, planning information, electrical inspection report and any other documents required depending on the property.

At the same time, we prepare to showcase it effectively: professional photographs, a virtual tour, a video where appropriate, and preparation of the property listing.

2. Marketing and the offer

Once the property is ready, we begin marketing it, arrange viewings and follow up with prospective buyers.

When a serious offer is made, we review it with you and also assess the prospective buyer’s financial standing, particularly their ability to secure financing. We then support you throughout the negotiations until an offer is potentially accepted.

The sale agreement is then prepared and signed, generally with the involvement of the notaries. If the purchase is subject to a financing condition precedent, it is then necessary to wait for this condition to be met within the stipulated period.

3. The sale agreement and authentic deed

After the sale agreement has been signed, the notary carries out the various checks and legal formalities required for the sale: mortgage status, planning matters, taxation and other searches relating to the property.

Once the file is complete, a date is set for the signing of the authentic deed. The balance of the purchase price is then paid and ownership of the property is officially transferred to the buyer.

It generally takes several months between the acceptance of an offer and the authentic deed, depending on the circumstances of the transaction.

Throughout the process, J&J Properties remains your main point of contact and liaises between you, the buyer and the notaries to help ensure the transaction proceeds smoothly.

For further information, we also provide a detailed explanation of every stage of a property sale in a dedicated article on our blog.

When a property is marked as ‘under option’, this means that a prospective buyer or tenant has expressed a firm interest in the property and that an agreement or process is currently being finalised.

During this period, the property is generally withdrawn from the market temporarily and new viewings are suspended.

For a rental property, this usually means that an application has been accepted and we are awaiting completion of the file or signature of the lease.

For a sale, it may mean that an offer has been accepted and the parties are finalising the next steps in the transaction.

However, the property has not necessarily been definitively sold or let at this stage. If the current process does not proceed, it may be placed back on the market.

Still interested in a property under option? Please provide us with your contact details so that we can get back to you if it becomes available again.

There is no absolute minimum budget. Nevertheless, to consider a property investment on a sound basis, we generally recommend having at least €50,000 of your own funds available to invest.

J&J Invest assists a wide range of clients, from investors making their first purchase to professional investors seeking to grow or diversify their assets.

We therefore structure acquisitions ranging from studios and flats to investment properties or portfolios comprising several buildings.

Our approach remains the same regardless of the size of the project: we start with your own funds, financing capacity and objectives to identify and structure the most appropriate investments.

The notary is a public official who plays an essential role in ensuring the legal security of a property sale.

In particular, the notary verifies the title deed, the property’s mortgage status, any easements, and the various legal, planning and tax matters required for the transaction. The notary prepares or reviews the preliminary sale agreement and subsequently drafts the authentic deed of sale.

When the deed is signed, the notary also manages the financial aspect of the transaction: receiving the necessary funds, ensuring payment of the purchase price to the seller, repaying any mortgage debts, and collecting the duties and costs associated with the purchase.

The notary then completes the formalities required to make the sale enforceable against third parties, particularly by registering the deed with the relevant authority. The notary’s involvement therefore guarantees the legal security of the transaction and the transfer of ownership.

The seller and buyer may each appoint their own notary. Having two notaries does not normally increase the notarial fees for the transaction: the notaries divide these fees between themselves.

At J&J Properties, we remain in contact with the notary or notaries throughout the process to provide the necessary information and facilitate the management of the file until the authentic deed is signed.

A property audit allows you to take a step back and assess a property or your entire portfolio to determine whether it is genuinely optimised.

In particular, we analyse the current value of the properties, rental income, profitability, costs, risks and existing financing, as well as any potential opportunities for improvement or value enhancement.

The main objective is to identify practical measures that could improve the performance of your property assets: adjusting the rent, carrying out certain works, refinancing, selling an asset that is no longer suitable, reinvesting differently or simply confirming that the current strategy is the right one.

The audit can therefore cover either a single property or a portfolio comprising several flats or buildings.

At the end of our analysis, we provide you with a clear report setting out our findings and recommendations, enabling you to make informed decisions about the next steps in your property strategy.

The process differs slightly depending on whether you wish to view a property for rent or for sale.

For a rental property, you can generally make an appointment directly on our website by selecting a suitable time slot from those available. You will then receive a confirmation email.

If you wish to reschedule or cancel your viewing, you can do so directly from this email using the “Change my viewing time” or “Cancel my viewing” buttons.

For a property for sale, appointments are arranged directly with our team by email or telephone.

Once the appointment has been confirmed, you will receive the practical details and the mobile number of the J&J agent responsible for your viewing. If you need to change the time or let them know that you are running late or unable to attend, the easiest option is to send them a WhatsApp message directly.

In all cases, if you need to cancel or reschedule a viewing, please let us know as soon as possible so that the time slot can potentially be offered to another applicant.

When selling a property, it is important to compile a complete administrative and technical file. This ensures compliance with legal obligations, reassures prospective buyers and prevents a missing document from delaying the sale.

Depending on the type of property, its location and the Region in which it is situated, the main documents required include:

• the title deed;
• the EPC (Energy Performance Certificate);
• the electrical installation inspection report;
• the planning and cadastral information;
• soil-related information or certificates, where required;
• documents relating to any oil tank;
• permits, plans and documents relating to any works or alterations carried out at the property;
• the asbestos certificate or inventory, where required;
• any other specific certificates or attestations that may be required depending on the property and its location.

If you are selling a flat or a jointly owned property, an additional file must also be obtained from the managing agent. This includes the basic deed and the co-ownership regulations, the minutes of the latest general meetings, service charge statements, the co-ownership accounts, the status of the reserve fund and working capital fund, as well as information relating to any works that have been approved or are under consideration and any debts owed by the co-ownership.

If the property is currently let, you will also need to gather the tenancy agreement, the inventory of fixtures, information relating to the rental deposit and any other relevant documents concerning the current tenancy.

The exact list may therefore vary considerably from one property to another.

When you entrust the sale of your property to J&J Properties, we identify the necessary documents from the outset and assist you in gathering them. We can also handle some of the formalities with the relevant authorities, the managing agent and the various parties involved on your behalf.

Preparing a complete file in advance helps reassure buyers, anticipate any potential difficulties and ensure that the sale proceeds smoothly.

As soon as you contact us about a property search, we create a personal search profile for you. You will then receive an email containing a link that takes you directly to your personal page.

From this page, you can update your personal information and manage your search criteria at any time.

You can also create one or more separate searches, each with its own criteria: geographical area, budget, property type, number of bedrooms or other desired features.

As soon as a new property matching one of your searches becomes available, you will automatically receive it by email.

Have your criteria changed? Simply update them from your personal page so that future suggestions reflect your new requirements.

If you no longer know how to access your personal page, simply send us an email. Our team will resend your direct login link.

Yes. Where required by the project, we can assist you with the various administrative procedures, particularly in relation to planning matters: permits, regularisation, change of use or major renovation.

For tax, legal or accounting matters, we work with property specialists to whom we can refer you. The aim is to provide comprehensive support throughout the project, while bringing in the appropriate specialist whenever a matter falls outside our area of expertise.

Of course. Many foreign investors and expatriates invest in Belgian property without living in the country.

J&J Invest can assist you remotely throughout the process: defining your strategy, searching for and analysing opportunities, viewings, acquisition, coordination of the various parties involved and, if necessary, supervision of works. Meetings can easily be arranged by video call and documents shared online.

Our teams can therefore act as your local representative and assist with numerous procedures, saving you from having to travel to Belgium each time.

Once the property has been acquired, J&J Properties and J&J Management can also handle its letting and day-to-day management.

However, the tax and legal position and financing options may vary depending on your country of residence and personal circumstances. Where necessary, we can refer you to specialists to ensure that your investment is structured correctly.

The aim is to enable you to invest in and manage a property portfolio in Belgium with the same visibility and support as if you were there in person.
