A real estate life annuity involves selling your home in exchange for a monthly income for life. The seller can continue living in the home or move out, depending on the terms of the agreement.
This option is typically considered by older adults who own a home and have a modest pension, either because they have no heirs or because they do not intend to leave the home to anyone. It is a financial decision that is difficult to reverse, so it’s important to understand it thoroughly.
At Domoblock, we analyze more than 100 properties per week and are seeing an increasing number of homes offered under this arrangement. We’ll explain how it works, how it’s calculated, how it’s taxed, and what risks it entails for each party.
What is a real estate life annuity, in legal terms: a contingent contract governed by Articles 1802 through 1808 of the Civil Code. The debtor agrees to pay an annuity for the lifetime of one or more persons in exchange for a principal asset—in this case, the home—which the debtor receives “of course, subject to the annuity obligation” (Art. 1802).
It is contingent because no one knows how much will be paid: it depends on how long the annuitant lives.

There are two parties:
In practice, when a property is transferred, the transaction is formalized in a public deed before a notary and registered in the Property Registry.
How the life annuity works, from the appraisal to the end of the contract:
The real estate life annuity comes in several forms. Any of these can be combined with an initial lump sum plus a smaller annuity payment.
The annuitant sells the bare ownership and reserves the usufruct or a right of habitation: they continue to live in their home until their death. The annuity is lower because the buyer cannot use the home. This arrangement is suitable, for example, for a 78-year-old childless widow who does not want to move.

The annuitant vacates the home, and the annuity payment is higher. This option is suitable for someone who is moving into a nursing home and needs to pay for it. In this case, it usually makes sense to request a lump-sum payment to cover initial expenses.

The annuity payment changes over time: higher in the early years and lower later, or vice versa. This is suitable for someone who anticipates high short-term expenses, such as home modifications, or for someone who wants to protect against inflation with a rising annuity payment.

There is no legally mandated formula for calculating a life annuity. Each payer uses their own formula, but the factors are always the same:
These two examples of real estate life annuities are illustrative: they are not actual offers. The outcome depends on the appraisal and the specific financial institution.

Primary residence appraised at €200,000. The owner sells the bare ownership, retains the usufruct, and agrees to a monthly annuity of €750. If they live for their 13.97-year life expectancy, they will receive approximately €125,730. To receive the tax value of the bare ownership (€172,000), they would have to live another 19 years, until age 94.
The fact that the total amount doesn’t reach the full value doesn’t mean it’s a bad deal: you continue to live in your home, and the buyer assumes the risk that you might live longer. But it’s important to look at the numbers.
Primary residence appraised at €150,000. An 82-year-old person hands it over free of charge and agrees to an initial payment of €20,000 plus €900 per month. With a life expectancy of 9.14 years, they would receive approximately €118,712. To receive the remaining €130,000, they would have to live another 12 years.
A real estate life annuity has clear advantages and risks that should be addressed head-on.
Our advice: Sign only after the deed has been reviewed by your notary and an independent advisor—not by the buyer.
Taxation of the life annuity occurs at two stages: the sale and the receipt of each annuity payment. Information current as of 2026; verify your specific situation with the Tax Agency or a tax advisor.
When you transfer the home in exchange for an annuity, the capital gain is the difference between the actuarial present value of the annuity and what you paid for the home (Art. 37.1.j of the Personal Income Tax Law).
If you are over 65 years old and it is your primary residence, that gain is exempt (Art. 33.4.b). If you have moved to a nursing home due to age or disability, it remains your primary residence until the time of the move (Art. 41 bis.3 of the Personal Income Tax Regulations).
This should not be confused with another scenario: selling any property while over 65 years of age and reinvesting the proceeds in a guaranteed life annuity within six months. In that case, the gain is exempt up to €240,000 (Art. 38.3 of the Personal Income Tax Law).
Life annuities received in exchange for a lump sum are only partially taxed: a fixed percentage based on age at the time they are established (Art. 25.3.b of the Personal Income Tax Law). This is considered a return on investment and is included in the savings base. The percentages are:
In the first example, out of €9,000 per year, only €720 is subject to tax.
All three options generate income from the home, but they aren’t all that similar. The sale of bare ownership with a reserved right of usufruct is, in fact, a form of life annuity if the proceeds are received as an annuity. You can find more details about reverse mortgages in our guide.
Investing in life annuities attracts insurance companies, specialized firms, and some individuals. The appeal lies in purchasing below market value and paying in installments.

But the investor assumes three risks. First, longevity: if the annuitant lives much longer than expected, the investor pays more than the home is worth. Second, the occupied home: the investor cannot use or rent it out while the annuitant is alive. Third, liquidity: reselling a home encumbered by an annuity is difficult.
From a tax perspective, when the annuity ends, the payer calculates their gain or loss as the difference between the value of the property received and the total annuity payments made (Art. 37.1.i of the Personal Income Tax Law).
In our model, which involves projects with estimated durations of a few months, an asset with an uncertain lifespan does not fit. That is why we do not use it. If you are considering it, calculate scenarios for 5, 10, and 20 years before making a decision.
Real estate investment involves risks, including the potential loss of principal, and liquidity may be limited.
There is no legal minimum age: the Civil Code does not specify one. In practice, financial institutions typically require you to be 65 or 70 years old, because the annuity is calculated based on life expectancy. Additionally, the tax exemption on gains from selling your primary residence requires you to be over 65 years old (Art. 33.4.b of the Personal Income Tax Law).
You can only take legal action to recover overdue annuity payments and demand that future payments be guaranteed. Article 1805 of the Civil Code prevents you from reclaiming the home due to nonpayment. To be able to reclaim it, you must include an express resolutory condition in the deed and register it with the Property Registry.
It depends on what is agreed upon in the deed. If you retain the usufruct, ordinary expenses are typically the responsibility of the usufructuary, and the property tax (IBI) is paid by whoever holds the usufruct. Many contracts transfer all these expenses to the buyer in exchange for a slightly lower annuity payment. Review this before signing.
It’s difficult once it’s been signed. Termination is only possible by mutual agreement between the parties, due to a breach of a stipulated resolutory condition, or due to nullity. For example, a life annuity established in favor of a person who dies within 20 days due to a pre-existing illness is null and void (Art. 1804 of the Civil Code).
At Domoblock, we work with three types of projects: house flipping, building flipping, and new construction. We purchase, renovate, or develop properties with estimated timelines and a defined sales plan.
With our real estate co-investment opportunities, you can participate starting at €200, 100% online. It’s free for investors: you pay nothing directly, and Domoblock charges a 5% management fee, which is included in the project costs. The historical IRR of our projects is +15% annually; this is historical data and does not guarantee future returns.
Real estate investment involves risks, including the potential loss of principal, and liquidity may be limited: there is no secondary market; there may be delays in construction or sales; you may lose some or all of your invested capital; and this capital is not covered by the Deposit Guarantee Fund. Domoblock does not offer financial instruments regulated by the CNMV.
A real estate life annuity can supplement a pension and provide peace of mind, but it permanently changes the fate of the property. Before signing, request an appraisal, compare at least two offers, calculate how much you would receive over 5, 10, and 20 years, and review the deed with your notary. And talk to your family: it’s easier to do this beforehand than to explain it later.
This article is for informational purposes only and does not constitute tax, legal, or financial advice, nor is it an investment recommendation. The examples are illustrative and do not represent actual offers. Past performance is not a guarantee of future results. All investments involve risks, including the partial or total loss of principal: consult a notary and an independent advisor regarding your specific situation.
