The Bank of Portugal is preparing to tighten the rules on Portugal’s most generous mortgage scheme for young buyers. Two thirds of the state’s guarantee envelope has already been committed. The contract deadline is December 31, 2026. And here’s the part most of my under-35 clients didn’t know until I told them: this scheme isn’t just for Portuguese nationals. Any tax resident in Portugal under the age of 35 can use it.
If you’re a 28-year-old Dutch remote worker in Lagos, a 33-year-old Irish freelancer in Burgau, or a German couple paying €1,500 a month for a one-bedroom in Praia da Luz, this is the post you should have read six months ago. Let me walk you through what it actually is, who qualifies, and why I’d push you to act this year rather than next.
What the 100% mortgage scheme actually is
The Portuguese government created a public guarantee for housing credit in mid-2024. The mechanism is simple. When you apply for a mortgage on your first home, the state guarantees up to 15% of the loan amount to your bank. That guarantee lets the bank lend you 100% of the purchase price, with no deposit out of your own pocket.
The scheme isn’t a free gift. You still take out a real mortgage with a real bank. You still pay interest. The state isn’t paying for your home. It’s removing the single biggest barrier most young buyers face: the 20% deposit that takes a decade of saving to assemble.
Close to 100,000 under-35s have already been helped onto the property ladder through Portugal’s combined young-buyer measures, between the IMT tax exemption and this public guarantee. In 2025 alone, 25,000 new mortgages were signed under the guarantee, covering 42% of all under-35 home purchases in Portugal.
The eligibility most expats get wrong
I keep meeting young expats in the Algarve who assume this scheme is closed to them because it’s a Portuguese government programme. It isn’t. Here are the actual conditions:
- You are between 18 and 35 years old (inclusive)
- You are tax resident in Portugal with a Portuguese tax domicile
- You are buying your first permanent residence
- Your annual taxable income is up to €80,000 (the 8th IRS bracket)
- The property is priced up to €450,000
That’s it. No nationality requirement. If you have residency, an NIF, and you file your taxes in Portugal, you qualify. I have clients from the Netherlands, Ireland, Brazil, France and the UK who all meet these criteria. Most just didn’t know to ask.
Why I’d push you to act before year-end
Three reasons.
First, the Bank of Portugal is preparing to tighten. They’ve flagged a sharp rise in credit risk: the proportion of new young-buyer mortgages classified as high-risk jumped from 3% in 2024 to 21% in 2025. That’s the kind of jump that gets regulators nervous. When the central bank gets nervous, eligibility narrows.
Second, the envelope is filling. The government has now committed €2.3 billion to the guarantee. By March 2026, roughly two thirds had been used. If the current pace continues, the budget runs out before the deadline.
Third, the contract deadline. Every mortgage signed under the guarantee has to be formalised by December 31, 2026. After that, even if the budget isn’t exhausted, the scheme closes to new contracts. You don’t want to be the buyer who decided “next spring” and missed the window.
The mistake I see young expats making
The biggest one is renting “for one more year” while waiting for prices to drop. They won’t. I’m going to be direct here because I’d rather be useful than polite: if you’re under 35 in Portugal, on a stable income with your partner, and you’re still paying rent in 2027, you are paying someone else’s mortgage. With this scheme, you can flip that math.
Your first home doesn’t need to be your dream home. That’s the part most people get wrong. A T2 apartment in central Lagos, a renovated village house in Lagoa, a coastal flat in Portimão. None of these are forever homes for most of my clients. They’re the lever that gets you onto the property ladder, builds you equity for ten years, and then finances the move to the villa, the larger family home, or wherever life takes you next.
In the Western Algarve, €200,000 to €350,000 still buys you real options. A modern one-bedroom apartment in Lagos sits comfortably under €250,000. A two-bedroom in Lagoa or Portimão sits in the €250,000 to €320,000 range. A small village house, often around €280,000 with a renovation budget on top. None of these are dream homes. All of them are first homes that build equity.
What this actually costs you to start
The most common follow-up question is what the monthly payment looks like in real life. For a €280,000 purchase financed at 100% over 35 years at current rates, you’re looking at roughly €1,300 to €1,500 a month, depending on the bank and your profile. That’s not far off what you’re paying in rent for a T2 in Lagos right now. The difference is that one of those numbers builds your equity. The other builds your landlord’s.
If you want a fuller breakdown of how the buying process works in Portugal as a foreign resident, including NIF, banking, and timelines, I’ve covered that in the full Portugal buyer’s guide.
The action step
If you are under 35, tax resident in Portugal, and you have ever asked yourself whether it makes sense to stop renting, this is the conversation to have this month. Not next year. Not after summer. This month. I have a one-page document that explains the eligibility conditions in plain English. Get in touch through the form on this site or on WhatsApp and I will send it across.
Your first home finances your dream home. That is not a slogan. It is how the people I know who own villas in their forties got there.
