Yes, US citizens can borrow in Portugal
Portuguese banks lend to Americans. Nationality is not the deciding factor — residency is. A US buyer who has not yet moved to Portugal is treated as a non-resident, with tighter loan-to-value limits and a more conservative reading of income.
One important difference from the US market: the loan is always in euros, terms are usually shorter than the 30-year American standard, and there is no equivalent of a nationwide credit score. Banks build their own picture from your documents.
How much a bank will lend
Expect financing of 60% to 80% of the purchase price or the bank valuation, whichever is lower. That means a 20–40% deposit, plus acquisition costs. If you move your residency to Portugal, the same banks can go to 90% — worth planning around if a move is already on the cards.
Dollar income, euro loan
Banks recognise dollar income, but apply a haircut for currency risk. Self-employment, RSUs, bonuses and rental income each need two years of history and are weighted conservatively. Repayments are in euros, so build exchange-rate movement into your budget rather than assuming today's rate.
US paperwork Portuguese banks expect
- Passport and a Portuguese tax number (NIF) — obtainable remotely.
- Last two federal tax returns (form 1040), with schedules if self-employed.
- Recent pay stubs or W-2s, and six months of bank statements.
- A credit report from a US bureau.
- FATCA and source-of-funds declarations when opening the Portuguese account.
FATCA reporting makes some banks slower with US clients than with other nationalities — one reason to approach several at once rather than one at a time.
The 7.5% IMT on non-primary residences
Since 2026, property that will not be your primary residence is taxed at a flat 7.5% IMT rate. Add 0.8% stamp duty on the purchase, 0.6% on the loan, plus notary and registration fees. Run the whole figure in the mortgage simulator before you commit.
Timeline
Two to six weeks from a complete file to a formal offer, then a few weeks to the deed. US applicants most often lose time on apostilled documents and bank compliance checks, so start early and send everything in one batch.
