Deposit size is usually the first question expats ask, and reasonably so – it’s the biggest single number standing between you and a mortgage offer. The honest answer is that it depends heavily on your specific situation, but there are clear patterns worth knowing before you start saving or house-hunting.
Typical Deposit Ranges by Situation
As a general starting point:
- Residential purchase, straightforward profile: often 20-25%
- First-time buyer expats: also typically 20-25%, sometimes higher without a prior UK mortgage track record
- Buy-to-let: commonly 25% or more, since rental cover requirements often push lenders toward a lower loan-to-value
- High value purchases (£1M+): often 25-40%, particularly for larger or more unusual properties
These are starting points, not guarantees – your actual required deposit depends on the specific lender, your income currency, and the property itself.
Why Expats Often Need Larger Deposits Than UK Residents
Lenders price in additional risk for non-resident applicants – harder income verification, currency exposure, and less straightforward legal recourse if something goes wrong. A larger deposit reduces the lender’s exposure and often opens up a wider range of lenders willing to consider your application at all, not just better rates.
Does Your Income Currency Affect the Deposit Required?
Often, yes. GBP, USD and EUR income tends to attract more standard deposit requirements. Income in less common currencies can push the required deposit higher, since lenders factor in additional currency and verification risk. Our Foreign Passport Holder Mortgages page covers how currency and visa status interact with lending criteria more broadly.
Can a Gifted Deposit Count?
Yes, and it’s common – particularly for first-time buyer expats. Lenders will want a signed gift letter confirming the money is genuinely a gift, not a loan, plus evidence of where the funds came from. This needs setting up correctly from the outset, not as an afterthought once your application is already underway. Our First-Time Buyer Expat Mortgages page covers this in more detail.
Does a Bigger Deposit Actually Get You a Better Rate?
Usually, yes – loan-to-value bands genuinely affect pricing, and dropping from, say, 85% LTV to 75% LTV can meaningfully improve the rate on offer. Beyond opening up more lenders willing to consider you at all, a larger deposit often pays for itself over the life of the mortgage through a lower rate. If you’re already a homeowner looking to release equity rather than raise a fresh deposit, our Expat Residential Remortgage page covers how that loan-to-value calculation works on a remortgage instead.
Frequently Asked Questions
What’s the minimum deposit for an expat mortgage?
There’s no single figure across the market, but 20% is a realistic minimum starting point for most straightforward residential cases; buy-to-let and more complex situations often require more.
Can I use savings held in a foreign currency as my deposit?
Yes, though you’ll need to show the funds converting into sterling with a clear paper trail, and be aware that exchange rate movements between now and completion can affect exactly how much you end up with once converted.
Will a smaller deposit mean fewer lenders will consider me?
Often yes – some lenders set higher minimum deposits specifically for expat and non-resident applicants, so a smaller deposit can narrow your options considerably.
Does the deposit requirement change for buy-to-let versus residential?
Yes, buy-to-let typically requires a larger deposit than residential, partly reflecting the rental cover calculations involved.
