The mechanism of a lease with purchase option

The lease with purchase option (or rent-to-own) is a hybrid contract that combines:

  1. A standard lease: the tenant occupies the property and pays monthly rent
  2. A promise to sell: the landlord commits to selling the property to the tenant at a price fixed in advance

The tenant has an option: they may purchase the property during the lease or at its expiry, at the price agreed in the contract. If they do not exercise the option, they simply leave the property.

This mechanism has little specific regulation in Belgium — it falls under general contract law and freedom of contract. There is no specific legislation comparable to the French PSLA.

Contract drafting

The absence of a specific legal framework makes the drafting of the contract crucial. Have it reviewed by a notary or a legal specialist in property law.

Advantages and risks

For the tenant (future buyer)

For the landlord (future seller)

AdvantageRisk
Motivated tenant (future owner)Price locked (no benefit if market rises)

Essential contract clauses

The contract must specify:

  1. The sale price: fixed or with an indexation formula
  2. The option period: throughout the lease or at expiry only
  3. The rent allocation: what percentage of rent is deducted from the sale price (0 to 100%)
  4. The exercise conditions: notification deadline, form (registered letter, notary)
  5. The causes of forfeiture: non-payment, damage, subletting
  6. The rental deposit: separate from the deposit on the price
  7. Notary fees: who pays in case the option is exercised

Without these clauses, the contract is a source of disputes. Involve a notary in drafting.

Taxation

During the rental phase

Rent is taxed as standard rental income. Consult our guide on tax returns for rental income.

In case of sale

RegionRegistration dutiesCapital gains
Brussels12.5% of priceNot taxed if > 5 years
Wallonia12.5% of priceNot taxed if > 5 years
Flanders3% of price (sole dwelling)Not taxed if > 5 years

If the portion of rent allocated to the sale price is significant, the tax authorities may reclassify part of the rent as a deposit on the price. In that case, registration duties are calculated on the total price (allocated rent + balance).

To secure the transaction, engage a notary. For day-to-day management of the lease before the option is exercised, use our rental management software. For more information, consult our guide on residential leases in Belgium.
