In short: NPL investing in Spain can be profitable, but there is no reliable average figure: the numbers in circulation come from players with a commercial interest and are not comparable with each other.
- Published figures range from 15%-30% a year to 40%-80% on capital over processes lasting 12 to 36 months, all from industry sources.
- There are no independent statistics on average NPL returns in Spain.
- The mortgage default rate stood at 3.8% at the end of 2025 (Spanish Mortgage Association) and foreclosures rose 38% in the first quarter of 2026 (Merca2).
- In the hypothetical example, the same debt returns +59% in 10 months or -19% in 34.
Investing in defaulted mortgage debt (non-performing loans) can offer higher returns than traditional real estate investment, but the figures circulating in the industry do not agree with each other, and that lack of agreement is in itself the most honest data point anyone can give about this market. Some platforms talk about returns of 15% to 30% a year; others about returns of 40% to 80% on capital across a whole process lasting 12 to 36 months; one particular firm has published a case with an annualised IRR of 24.4%. None of these figures comes from independent statistics, and the real return depends on the specific court process, with a risk of partial or total loss of capital.
What "return" means when we talk about an NPL
The return on an investment in defaulted mortgage debt is what is left after subtracting, from the amount finally recovered, the price paid for the loan and all the costs of the process. That recovered amount can come through three routes: collecting the debt from the debtor, selling the property once the court has awarded it, or reselling the loan itself to another investor. And the costs are not only the purchase price: they include legal fees, court fees and costs, any eviction proceedings, refurbishing the property and the taxes on the transaction.
The discount at which the loan is bought is therefore not the return: it is only the starting point. The variable that most shapes the outcome is time, because the same gross margin earned in 10 months or in 34 makes for two completely different investments. That explains much of the confusion around industry figures: some sources publish the annualised IRR of a specific case and others the cumulative total return of a process lasting several years, and those figures cannot be compared.
What return figures have actually been published, and why they vary so much
The most concrete figures we found while researching this article come from cases published by Equus Capital, a firm active in this market: €55,000 of net profit in 60 days on a €160,000 investment, and an annualised IRR of 24.4% on a judicial auction process in Madrid resolved in 9.5 months (Equus Capital). Other industry platforms consulted for this article quote different and in some cases much higher figures: returns of 15% to 30% a year according to some sources (fiscalizarte), and returns of 40% to 80% on invested capital across a whole process of 12 to 36 months according to others (Subastanomics; jammestate).
Why this spread of figures is the most useful information you can have before investing. Each of these figures comes from a party with an interest in showing favourable results (what financial analysis calls survivorship bias), and each uses a different calculation method (the annualised IRR of a specific case, a total-return range over a multi-year process, a generic estimate of "expected return"). In our research we found no statistics on average returns in the Spanish NPL/REO market published by an independent source: not the Bank of Spain, not the CNMV, not an academic study. When five sources from the same industry, all with a commercial interest in the subject, give five different figures ranging from 15% a year to 80% over a whole process, the reasonable conclusion is not that the average lies somewhere in between, but that there is no reliable market figure, and anyone presenting a specific return as "normal" or "expected" in this market should prompt you to ask exactly where it comes from.
What can be verified with an independent source is the market context: the mortgage default rate in Spain stood at 3.8% in the fourth quarter of 2025 according to the Spanish Mortgage Association (Asociación Hipotecaria Española), with the Bank of Spain warning that it could approach 6% in 2027 if pressure on variable-rate mortgages continues (El Economista; Euribor.com.es), and foreclosures rose 38% year on year in the first quarter of 2026 (Merca2). That confirms the market is active, not that returns are guaranteed. On the other side of the ledger, bear in mind that one of the largest holders of repossessed property in Spain, Sareb (the so-called bad bank set up in 2012 to take toxic real estate assets off the books of rescued banks), stopped selling to private individuals in March 2025 and is transferring much of its portfolio to the public affordable rental stock: part of the supply that fed this market is shrinking, not growing (covered in REO properties in Spain).
One asset, two possible endings: a hypothetical example
Hypothetical figures built to illustrate the range of possible outcomes, not a documented real case. The same mortgage debt, two ways the process can unfold.
| Item | Favourable scenario | Adverse scenario |
|---|---|---|
| Purchase price of the debt | €60,000 | €60,000 |
| Legal and court costs | €6,000 | €12,000 (longer, more complex process) |
| Months to resolution | 10 months | 34 months |
| Outcome | Court award and sale at €105,000 | Debtor exercises the article 1535 redemption right or negotiates a partial write-down; €58,000 recovered |
| Return on investment | +59% in 10 months | -19% in 34 months |
Hypothetical example built to show the real range of possible outcomes, not a forecast or a market average. Both scenarios are plausible depending on the status and complexity of the court file at the time of purchase.
The real legal risks, one by one
| Risk | What it involves | Where we cover it in depth |
|---|---|---|
| Uncertain court timelines | Mortgage foreclosure proceedings in Spain can take 12 to 24 months in standard cases, and 4 to 6 years in complex ones | Buying mortgage debt (what an NPL is) |
| Redemption of a litigious claim (retracto de crédito litigioso) | If you buy an individual loan that is already in litigation, the debtor can extinguish it by paying you only what you paid for it (article 1535 of the Civil Code), within 9 days of your demand for payment | Buying mortgage debt (what an NPL is) |
| More capital tied up at auction | The deposit required to bid rose from 5% to 20% of the appraised value under the reform introduced by Organic Law 1/2025 (Ley Orgánica 1/2025), in force since April 2025 | The BOE auction portal |
| Strict procedural formalities | A missed deadline or a formal error in a cesión de remate (assignment of the auction bid) can void the deal | Assignment of the auction bid |
| Unknown condition and encumbrances at purchase | At a judicial auction you usually cannot visit the property or know all the encumbrances before bidding | The BOE auction portal |
| Occupancy and eviction | Taking physical possession may require an additional court procedure of 6 to 18 months, and up to 4 years in the most contentious cases | Buying an occupied property |
| Total illiquidity of capital | Capital is tied up for the whole process, with no option of a partial sale and no guaranteed early exit | This article |
| Regulatory and large-holder (gran tenedor) risk | An investor holding several properties through a company may face longer protection periods for vulnerable occupants | Buying an occupied property |
Is NPL investing in Spain safe?
It is one of the riskiest segments of real estate investment in the Spanish market. The very source of the discount at which these assets are bought (market sources cite ranges from 20% to 70% of face value or of the underlying property, depending on exactly what is being compared) is the flip side of a court, operational and liquidity risk that the selling bank would rather transfer than carry. No investment with that discount-to-risk profile can be called safe.
How to decide whether this market fits your profile
Investing in defaulted mortgage debt can deliver real returns, but the figures circulating in the industry are built to sell, not to inform neutrally, and their lack of consistency across sources is the clearest proof of that. Before committing capital, understand the full process from what an NPL is to buying an occupied property, and consider whether your risk profile and time horizon fit a market where the outcome can take years to confirm.
Frequently asked questions
How much can you really earn investing in defaulted mortgage debt?
There is no reliable, representative market figure. Published returns range from 15% a year to 80% on capital across a whole process, depending on the source, and all of them come from players with an interest in showing them in a favourable light. The real result depends on the status of the court file, the type of property and how long the process takes to resolve, and it can be negative.
Is investing in NPLs riskier than traditional real estate?
Generally yes, because it adds court risk, the specific risk of redemption of a litigious claim and occupancy risk on top of the usual property risks (vacancy, unpaid rent, price swings). It is not directly comparable with buying a home to let in the conventional way.
How are gains from investing in NPLs or REOs taxed?
It depends on the legal structure of the deal (individual or company) and the type of gain. Reental does not provide individual tax advice: consult your tax adviser before investing in this market.
Why don't the return figures I see on different websites match?
Because each one comes from a platform or firm with a commercial interest in the market, using different calculation methods (the annualised IRR of a specific case, a total-return range over several years, a generic estimate). As of this guide, there are no independent statistics on average NPL returns in Spain. The spread itself (from 15% a year to 80% over a whole process) is the clearest sign that none of them is a reliable market average.
Is there a lower-risk way to invest in this market?
Reducing the specific risk of defaulted mortgage debt usually means diversifying across several cases or delegating selection to specialist managers with a verifiable track record, which spreads the risk rather than eliminating it. If you are looking for real estate exposure with liquidity and without managing a lawsuit yourself, fractional investment through Reental is a different route, with its own risk and return profile.
If you want the potential return of defaulted mortgage debt without taking on the court process or the total illiquidity of capital yourself, at Reental we turn this kind of asset into fractional investment with a secondary market: explore Reental's active projects.
