Portugal's youth mortgage scheme 2026: how to buy a home with 100% financing (before it ends)
The public guarantee lets under-35s buy a first home in Portugal with no deposit — but contracts must be signed by 31 December 2026. The step-by-step guide.
If you are 35 or under and want to buy your first home in Portugal without a saved-up deposit, the clock is ticking: the public guarantee that enables 100% mortgage financing for young buyers is currently set to run only until 31 December 2026 — and the contract must be signed by then. Here is how the scheme works, who can use it and what to do now.
How does 100% financing for young buyers work?
In a standard Portuguese mortgage, the bank finances up to 90% of the property’s value and the buyer covers the remaining 10% — easily €20,000 or €30,000 that many young people simply do not have. With the public guarantee, the State steps in as guarantor for up to 15% of the property’s value, allowing the bank to lend the full 100%. The State has reinforced the guarantee fund by €350 million, a sign of how strong demand has been: young buyers have gained weight in the market and the average buyer age has fallen since the measure began.
Who qualifies for the scheme?
The essential requirements: be aged 18 to 35, buy your first permanent own home, and not own another residential property. At the branch, each bank then assesses affordability as with any mortgage — the State’s backing does not replace an income compatible with the monthly payment. Conditions help: with the ECB holding its key rates steady, banks expect a strong year for mortgage lending. Foreign residents can qualify too, provided they meet the same criteria — tax residence in Portugal included.
Which taxes are waived?
The same age group benefits from IMT (property transfer tax) and Stamp Duty exemptions on a first home, with full exemption up to a price of €330,539 — we covered the thresholds in detail in our IMT Jovem guide. Adding the tax break to 100% financing, a young buyer can now purchase a home with practically no upfront capital — exactly the design that led the IMF to warn these supports, by heating demand without creating supply, may be feeding the very price rises they try to offset.
Step by step: what to do before December
First, confirm eligibility (age, first permanent own home). Second, request simulations from several banks and say upfront that you want to use the public guarantee — not all of them offer it unprompted. Third, sort your paperwork early: pre-approval, property valuation and the deed take weeks, and by year-end banks will be swamped with last-minute applications. The contract must be formalised by 31 December 2026; barring an extension the Government has not announced, a January signing misses the boat.
Frequently asked questions
How much can I borrow with the public guarantee? Financing can reach 100% of the purchase price or the bank’s valuation (whichever is lower), within the scheme’s price caps and your own borrowing capacity.
Does the guarantee cost anything? The State’s backing is not a subsidy — if you default, the State answers to the bank and then recovers the debt from you. It is a way in, not a discount.
What if the home costs more than €330,539? The IMT exemption stops being total above that price and phases out at higher brackets; the public guarantee also has a price ceiling. Luxury homes sit outside the scheme’s design.
