Buying Property in Belgium as a Foreigner: The Compromis, Regional Tax and Mortgage File

A foreign buyer can enter Belgium's ordinary property-purchase process, but should not sign an offer or sale agreement until financing, legal capacity and regional tax treatment are clear. The Belgian compromis de vente is not a casual reservation: once buyer and seller agree on the essential terms, it can create binding obligations. A notary then investigates title and planning matters, prepares the authentic deed and completes registration. Mortgage approval remains a separate lender decision, especially when income, residence or assets are outside Belgium.

Buying a Belgian home does not by itself grant a residence permit, tax residence or citizenship. Property ownership and immigration status are separate legal questions.

The transaction begins before the notarial deed

Belgium.be describes the sale agreement as the document drawn up when buyer and seller agree on the terms. The notarised deed later legally seals the transfer. This means the buyer's risk starts before the final appointment.

Before signing, make sure the agreement addresses:

exact property and included fixtures;
price and deposit;
financing condition;
planning and permit information;
energy and inspection records;
occupancy and handover;
existing leases;
deadline for the authentic deed;
consequences if a condition fails.

A generic financing clause may not protect a foreign-income applicant if the amount, deadline or required applications are unrealistic. Ask the notary or lawyer to review it before signature.

Use the notary early

A Belgian property transfer requires a notarised deed. The buyer and seller may use the same notary or different notaries; Belgium.be notes that, when two notaries are involved, they share the fee rather than charging the buyer a second full notarial fee.

The buyer's notary can help check:

ownership and mortgages;
cadastral information;
planning status and permits;
pre-emption or public-law restrictions;
apartment co-ownership documents;
outstanding building charges;
energy information;
tax and deed formalities.

The notary is not a building surveyor. Commission technical inspection appropriate to the property, particularly for moisture, roof, structure, heating and unapproved alterations.

Regional tax changes the cash requirement

Registration duty is a regional tax. FPS Finance states that the Regions determine the tax base, rate and reductions. For Brussels-Capital and Wallonia, the standard rate shown by FPS Finance is 12.5% of the agreed price and related charges, subject to the applicable rules and reliefs. Flanders administers its own registration duty and rates.

A new property may be sold under VAT instead of registration duty in certain circumstances. Do not add both systems as if they always apply simultaneously.

Your cost sheet should separate:

Cost	Why it varies
Registration duty or VAT	Region, property type and available relief
Notarial act costs	Price, searches, mortgage and formalities
Mortgage deed/security costs	Loan and security structure
Bank costs	Valuation, file and product charges
Technical inspection	Property and scope
Insurance	Building, borrower and coverage choices
Renovation reserve	Condition and legal compliance

Ask for a notarial calculation for the specific property. Online percentages do not capture every relief or deed cost.

Mortgage access with foreign income

EU rules do not require a Belgian lender to accept a mortgage application. A lender must assess creditworthiness and may consider where you live, where you work and where income is paid.

For foreign or cross-border income, prepare:

employment contract and recent payslips;
bank statements showing salary;
tax return or assessment;
residence and work status;
existing loans in all countries;
explanation of bonus, commission or self-employed income;
translations where requested;
deposit and transaction-cost evidence.

A bank may lend a smaller proportion when the applicant is non-resident, the income is difficult to enforce or the property is investment rather than an occupied home. Treat every deposit percentage as lender-specific until confirmed in writing.

When a binding mortgage offer is made, compare the ESIS, APRC, total repayable amount, rate structure, insurance and early-repayment conditions.

Due diligence for an apartment

An apartment purchase includes a share of the common property and obligations of the owners' association. Request:

recent general meeting minutes;
accounts and budget;
reserve-fund balance;
planned major works;
arrears attached to the unit;
building rules;
litigation or insurance claims;
private and common energy obligations.

A low sale price can be offset by a roof, façade, lift or heating project approved shortly after completion.

The cadastral and annual-tax layer

Belgium.be explains that annual property tax is based on cadastral income, a notional value used in Belgian property taxation. Ask the notary how the cadastral income, region and intended use affect your ongoing obligations.

A non-resident may also have reporting obligations in their country of residence. Obtain cross-border tax advice before assuming that Belgian property tax settles the entire position.

Two buyer scenarios

Luxembourg employee buying a home in Arlon

The buyer works in Luxembourg and earns in euros but purchases in Wallonia. The mortgage file should reconcile Luxembourg salary, Belgian residence plans and cross-border tax deductions. The compromis should contain a realistic financing condition, and the cost calculation should use Walloon registration rules rather than a Belgian national average.

Overseas investor buying a Brussels apartment

The buyer lives outside the EU and will rent the property. The bank may apply a non-resident or investment policy. The due-diligence file needs lease assumptions, co-ownership records, renovation risk and tax advice. Ownership does not create Belgian residence rights.

Offer-to-deed workflow

Choose a notary before making a binding offer.
Obtain property, planning and co-ownership documents.
Obtain a preliminary mortgage assessment based on real income evidence.
Draft an offer with appropriate conditions.
Sign the compromis only after understanding its binding effect.
Complete bank valuation and underwriting.
Let the notary complete searches and deed preparation.
Confirm registration duty/VAT and all completion cash.
Sign the authentic deed.
Update insurance, tax, utilities and co-ownership records.

Red flags

pressure to sign without a financing condition;
seller cannot produce planning or ownership records;
apartment minutes mention major works with no budget;
advertised floor area does not match official documents;
deposit requested to an unverified account;
promise that ownership guarantees immigration status;
cost estimate uses the wrong Region's tax rules.
