Expat mortgage LTV is the percentage of a UK property’s value that is being financed for a borrower who lives overseas. There is no single maximum LTV that applies to every expat mortgage. The amount a lender is prepared to advance depends on the complete borrower, property and transaction profile.
This guide focuses on overseas-resident mortgage LTV and deposit requirements. If your main issue is non-UK citizenship rather than living abroad, see our foreign national mortgage deposit guide. If your deposit is held overseas, see our overseas savings source-of-funds guide.
What does LTV mean?
Loan-to-value, or LTV, is the mortgage amount divided by the property value used by the lender, expressed as a percentage.
For example, a £200,000 mortgage against a property valued at £300,000 is about 66.7% LTV. In a straightforward purchase, the deposit percentage is broadly the other side of that calculation: 100% minus the LTV. So a 75% LTV mortgage implies roughly 25% deposit before fees and other transaction costs. The remaining equity or purchase deposit is not the same thing as fees, taxes or other transaction costs, which need to be budgeted separately.
What is the maximum LTV for an expat mortgage?
There is no universal maximum. Different lenders can set different LTV limits according to country of residence, income, currency, property type, mortgage purpose and wider risk criteria.
A borrower should therefore avoid planning around a generic statement such as “all expats can borrow 75%” or “expat mortgages are capped at 60%”. Those numbers may not apply to the actual case or the lender being considered.
Can an expat get a 90% LTV UK mortgage?
A 90% LTV mortgage means the mortgage covers 90% of the lender’s accepted property value, leaving 10% equity or deposit before fees and other costs. Whether that level is available to an overseas-resident borrower is lender- and case-specific.
It should not be treated as a standard expat product or assumed to be available simply because a UK-resident borrower might qualify for high-LTV borrowing. Country of residence, income currency, property use, property type, credit evidence and the lender’s current policy can all affect the maximum LTV.
What can affect expat mortgage LTV?
- Country of residence: lender appetite can differ between jurisdictions.
- Income and currency: some lenders restrict particular currencies or income structures.
- Residential vs buy-to-let: owner-occupied and rental-property mortgages use different affordability and underwriting approaches.
- Property type: construction, tenure, condition, location and intended use can affect lender security requirements.
- Credit profile: limited UK credit history can change lender choice, although it does not automatically prevent borrowing.
- Existing borrowing: other mortgages, debts and property exposure can affect the overall assessment.
- Ownership structure: personal borrowing and SPV/company borrowing are not assessed identically.
- Purchase vs remortgage: the lender may assess the available equity and requested borrowing differently.
Does a bigger deposit help?
A bigger deposit reduces the LTV. A lower LTV can widen lender or product options in some cases and reduces the lender’s exposure to the property.
But a larger deposit does not automatically solve other criteria problems. An unacceptable country of residence, unsupported income, unsuitable property or unclear source of funds can still prevent a case from fitting a lender.
Residential expat mortgage vs expat buy-to-let LTV
Residential and buy-to-let mortgages should not be treated as the same LTV market. Residential borrowing is primarily assessed around personal affordability and the property. Buy-to-let lending also gives substantial weight to expected or actual rent and the lender’s rental stress test.
If the UK property will be rented, use our non-resident buy-to-let mortgage guide for the rental-affordability side.
Expat, foreign national and non-resident are not interchangeable
This page uses “expat” in the practical mortgage sense of someone living outside the UK. That is different from foreign nationality. A British citizen living overseas can be an expat borrower, while a non-British citizen living in the UK can be a foreign-national borrower without being an overseas resident.
The distinction matters because residence and citizenship can lead to different lender criteria. Where both apply, both should be disclosed at the start of the mortgage review.
How valuation can change the final LTV
The lender bases LTV on the property value it accepts for mortgage purposes. If the lender’s valuation is lower than the agreed purchase price, the effective LTV can rise and the borrower may need more cash to keep the mortgage within the permitted band.
This is why the planned deposit should not be treated as final until the lender has assessed both the borrower and the property.
Documents that may affect an expat LTV assessment
- passport and identification;
- proof of current overseas address;
- income evidence where required;
- bank statements;
- deposit and source-of-funds evidence;
- details of existing mortgages and properties;
- property details and purchase price or current value;
- rental evidence for buy-to-let cases; and
- company documents where an SPV is borrowing.
Common expat LTV mistakes
- assuming an advertised UK-resident LTV applies to an overseas-resident case;
- treating one lender’s maximum LTV as a market-wide rule;
- confusing foreign nationality with overseas residence;
- forgetting that buy-to-let uses separate rental-affordability criteria;
- moving overseas deposit funds without preserving the evidence trail;
- assuming a larger deposit guarantees approval; and
- ignoring the effect of a lender valuation below the purchase price.
Frequently asked questions
Is there a standard maximum LTV for expat mortgages?
No. Maximum LTV is lender- and case-specific.
Can expats get 90% LTV?
Potentially in some circumstances, but it should not be assumed. The available maximum depends on current lender policy and the complete application.
Does a larger deposit mean a higher LTV?
No. A larger deposit means a lower LTV.
Can overseas savings be used for the deposit?
Potentially, subject to lender and conveyancer source-of-funds checks. See our overseas savings mortgage deposit guide.
