Need a precise figure?
Calculator results are estimates only and should be used as a planning guide before speaking with a specialist. Lending criteria and subsequent interest rates vary by country and depend on an applicant’s overall personal financial profile, property location, property valuation, amount borrowed and loan-to-value (LTV).
Why International Mortgages Are Different From Local Loans
Don’t rely on standard “at-home” figures
If you’re used to a local mortgage market, financing a property in a different country can be challenging. International lenders often assess risk differently, and many standard calculators miss key factors:
- Lower loan-to-value (LTV) for non-residents: Local-resident mortgages often offer higher LTVs because borrowers live and work in the country, earn in the local currency, and pay local taxes. Non-resident mortgages are typically capped at around 60–80% LTV, which means a larger deposit is usually required.
- Currency movements: If your income is in one currency and your mortgage is in another (for example, EUR or USD), exchange rate movements can change your effective monthly cost.
- Eligibility and age limits: Some countries impose stricter age limits, and life insurance may be required as part of the lending structure.
Get a Decision in Principle
To know exactly how much you could borrow, move beyond online estimates. A Decision in Principle / Agreement in Principle (AIP) helps you understand your realistic budget and can strengthen your position with sellers and agents.
How Much Can I Borrow for an International Mortgage?
Calculating your budget for an overseas property involves more than simple income multiples. International lenders typically look at:
Debt-to-income (DTI): This typically includes your existing mortgage(s), any other personal debt repayments, and the new overseas mortgage. Many lenders aim to keep total debt repayments below 33–35% of net monthly income, though this varies by country and lender.
Rental income: In most countries, projected rental income is not used (or is only used very cautiously) to support affordability for non-residents. The main exceptions are typically the UK and the USA, where rental income is more commonly used in affordability models.
Assets and liquidity: For higher-value purchases — often £2 million+ (or local-currency equivalent) — and high-net-worth/private banking routes, affordability may be assessed on a case-by-case basis, and the stricter DTI-style rules may not apply in the same way.
What Mortgage Types Are Available Overseas?
Products vary by lender and country, but you’ll typically see combinations of:
- Repayment mortgages
- Fixed-rate and variable-rate options
- Interest-only (rare and usually case-by-case)
Rather than quoting rates on the page (which change frequently), the most accurate approach is to use the calculator for planning, then confirm live pricing once your profile, property, LTV, and currency are known

Frequently Asked Questions
What is the minimum deposit for an overseas mortgage?
It depends on the country and your residency status. As a non-resident, it’s common to need a 20–40% deposit (around 60–80% LTV) in many markets, including parts of France and Portugal. Some lenders and countries may require more, depending on risk, property type and currency.
Do overseas mortgage rates differ from local mortgage rates?
Yes. Non-resident borrowers are often assessed differently from local residents, and pricing varies by country, currency, lender appetite, property type, loan term and LTV. The most reliable figure will come from a lender’s assessment of your exact scenario.
Will currency exchange rates affect my mortgage repayments?
Yes. If your mortgage is in a foreign currency but your income is in another currency, exchange rate movements can increase or reduce your effective repayment cost. Currency planning is an essential part of overseas property finance.
