Rent first, buy later. What you need to know.

In short

  • With rent-to-own you first live in the property as a tenant. Part of the rent is credited towards the purchase price that becomes due later.
  • The purchase price is fixed right at the start. Later price rises on the market no longer matter.
  • Because the deal is about buying property, the whole contract must be notarised. A rent-to-own contract signed privately is void.
  • A priority notice of conveyance (Auflassungsvormerkung) in the land register protects the buyer if the seller tries to sell the property to someone else or becomes insolvent.
  • Overall, rent-to-own is usually more expensive than a conventional mortgage. It can still make sense, for example if you lack equity or a bank will not (yet) lend to you.

How rent-to-own works

Rent-to-own combines two contracts you would otherwise know separately: a tenancy agreement and a purchase agreement. In practice both are combined in a single notarial deed. The process almost always follows the same four phases.

  1. Contract before the notary

    Buyer and seller agree on the purchase price, monthly rent, credited share and term. The notary records everything and usually applies for the priority notice in the land register.

  2. Rental phase

    The buyer moves in and pays rent every month. The agreed share is credited towards the purchase price. The rental phase typically lasts five to fifteen years.

  3. Time of purchase

    On the agreed date the remaining purchase price becomes due. Most rent-to-own buyers finance it with a bank loan, for which the credited payments now count like equity.

  4. Ownership

    Once the remaining price has been paid, both sides declare the conveyance. With the entry in the land register, the buyer becomes the owner.

Two models: purchase obligation or purchase option

Rent-to-own covers two types of contract that differ in one decisive point: whether the buyer must buy at the end or only may buy.

Rent-to-own with purchase obligationRent with purchase option
Decision to buyMade at once before the notary. The buyer is obliged to buy.Made later. The buyer can exercise the option or let it lapse.
FlexibilityLow. You can only exit under the terms of the contract.High. Without a purchase, the contract ends like a normal tenancy.
Rent already creditedGoes towards the purchase price for certain.Is usually lost if you decide not to buy.
Option feeNot usual.Often charged as the price for the right to buy.
Real estate transfer taxArises when the contract is signed.Usually only arises when the option is exercised.

Legal situation in Germany

There is no specific rent-to-own law. Instead, the rules for purchase contracts, tenancies and real estate transactions apply side by side. The most important points at a glance:

Notarisation of the whole contract

§ 311b BGB (Civil Code)

Anyone who commits to buying or selling land needs a notarised contract. With rent-to-own this also applies to the tenancy part where it is connected to the purchase, for example where it governs crediting, handover or term. Without notarisation, the entire contract is void. Payments already made must then be unwound, which often means disputes.

A purchase option also binds the seller and must therefore be notarised.

Priority notice of conveyance

§ 883 BGB

The priority notice is an entry in the land register that secures the buyer's future claim to ownership. As long as it is registered, the seller cannot validly sell the property to anyone else or encumber it to the buyer's detriment. For a rent-to-own deal over many years, it is the buyer's most important protection.

Tenancy law during the rental phase

§§ 535 ff. BGB

During the rental phase, residential tenancy law applies with its protections for tenants. This covers, among other things, termination, utility statements and defects. Contractual penalties are invalid in residential tenancy agreements § 555 BGB. Anyone who wants to divide repairs and maintenance differently from the law should set this out clearly in the notarial contract, as standard clauses often do not hold.

Consumer protection with commercial sellers

§ 506 BGB

If a business, such as a developer or housing company, sells to a private individual, rent-to-own can count as a financial accommodation for payment. The rules for consumer real estate loans then apply accordingly, including special information duties and a right of withdrawal. Whether this applies depends on how the contract is drafted and is a question for a specialist lawyer or the notary.

Real estate transfer tax

§ 1 GrEStG

The tax arises with the effective purchase contract. With a purchase obligation that is the notarisation at the start; with a pure purchase option it is usually only when the option is exercised. Each federal state sets its own rate, currently between 3.5 and 6.5 percent of the purchase price.

Seller insolvency

§§ 106, 108 InsO (Insolvency Code)

If the seller becomes insolvent, the residential tenancy generally continues. A registered priority notice is insolvency-proof: the insolvency administrator must fulfil the purchase claim. Without a priority notice, however, the buyer can lose the payments already credited.

Taxes for the seller

§§ 21, 23 EStG (Income Tax Act)

Until ownership passes, the rent is income from letting for the seller. If less than ten years lie between the seller's own purchase and the sale, the capital gain may also be taxable. It is worth talking to a tax adviser before the contract is drawn up.

Important: The legal situation always depends on the specific contract. Have the draft checked by an independent lawyer specialising in property or tenancy law before the notary appointment. The notary must remain neutral and does not represent either side.

Rent-to-own calculator

Play with the numbers. The example shows how much is credited at the end of the rental phase, what still needs to be financed and what rent-to-own costs overall. The values are examples.

Same down payment, and instead of rent you pay the same monthly amount as a loan instalment. The debt left after the rental phase is included.

Not included: interest on financing the remaining price, the property's running costs and maintenance. The part of the rent that is not credited is what you pay for living there during that time.

Who rent-to-own suits

For buyers

  • A path to ownership with little or no equity
  • A fixed purchase price protects against rising prices
  • Time to get to know the property and the area before buying
  • Time to build up creditworthiness for later financing
  • Total cost usually higher than with a bank mortgage
  • Few properties on offer, some in difficult locations or poor condition
  • Without a purchase, the credited share is often lost
  • A fixed price can become a disadvantage if prices fall

For sellers

  • A wider circle of buyers, even for properties that are hard to sell
  • Ongoing rental income until the sale
  • Often a higher purchase price than with an immediate sale
  • The full sale proceeds only arrive late
  • Risk that the buyer becomes unable to pay
  • Owner's duties and liability continue until handover
  • Tax consequences need careful planning
