Mortgages Abroad
The home you already own is usually the answer.
When people imagine moving abroad, they think about the destination. But the single biggest financial lever is almost always their UK property — and the mortgage attached to it. Here's how it actually works.
The starting point
Your mortgage is a relationship, not a product.
Most UK residential mortgages contain a clause requiring the property to be your main home. The moment you move abroad, that clause technically no longer applies — and how your lender responds depends entirely on the conversation you have with them.
There are four routes most relocating homeowners explore: keeping the existing mortgage with permission to let, switching to a buy-to-let, remortgaging before leaving, or selling and starting fresh. None of these is automatically the right answer.
"I assumed I could just keep my mortgage and rent the house out. My lender saw it very differently."
Option 1
Keeping your existing mortgage
If your move is short-term or genuinely uncertain, keeping the mortgage you already have is often the path of least friction. Your rate, your term and your monthly payment all stay the same.
The catch: if you intend to rent the property out, you almost certainly need Consent to Let from your lender first. Renting without it can void your buildings insurance and breach your mortgage terms.
Option 2
Consent to Let — the most common bridge
Consent to Let is a short-term permission, usually granted for 12–24 months, that allows you to rent your home while keeping a residential mortgage. Most high-street lenders offer it — but the criteria, fees and rate uplifts vary widely.
Illustrative example
A 12-month relocation trial
- Property value
- £420,000
- Remaining mortgage
- £190,000
- Existing rate
- 2.4% fixed (3 years left)
- Likely rent
- £1,650 / month
- Lender's Consent to Let fee
- £250 + 0.5% rate uplift
- Net monthly position after costs
- +£820 / month

Consent to Let suits people who want optionality — to try life abroad without burning the bridge home.
Option 3
Switching to a Buy-to-Let
If the move feels longer than two years, a proper Buy-to-Let (BTL) mortgage is often the better fit. Lending is assessed on rental income rather than your salary, which can actually make BTL easier to qualify for once you're overseas.
Expect a higher rate than a residential mortgage, larger arrangement fees, and a 25% minimum deposit. The trade-off is permission to let indefinitely, often on more flexible terms.
Option 4
Remortgaging before you leave
This is the option most people don't realise they have. Remortgaging while you're still a UK resident — and ideally still in UK employment — is dramatically easier than doing it from overseas. A lot of relocating homeowners use the months before their move to:
- Lock in a longer fixed rate for stability
- Release equity to fund the move itself
- Switch onto a product that explicitly allows letting
- Reduce monthly payments to make rental cover easier
"Sorting the mortgage before the move was the single best thing we did."
Borrowing once you're overseas
Yes, it's possible. No, it's not the same.
UK lenders are noticeably more cautious with expatriate borrowers. You'll typically need a larger deposit (30–40%), proof of stable overseas income in a recognised currency, and a UK bank account that's been kept active.
There's a small but specialist set of lenders who serve expats well. Rates are higher than residential equivalents, but the market is more open than most people assume — especially for buy-to-let purchases or remortgages.
Common mistakes we see again and again
Strengths
- Speaking to your lender before you move
- Sorting Consent to Let in writing
- Keeping a UK bank account active
- Locking a long fix while still UK-resident
Watch-outs
- Renting your home out 'quietly' without permission
- Cancelling the UK bank account on day one
- Assuming your residential mortgage 'transfers' to BTL
- Trying to remortgage for the first time once already abroad
Questions worth asking
Frequently asked
Do I need to tell my lender I'm moving abroad?+
Yes. Most mortgage agreements require you to notify the lender of any change in occupancy or residency. It's a short phone call, not a formal application.
Will my rate change if I ask for Consent to Let?+
Often yes — usually a small uplift of 0.25%–1%, plus a one-off fee of £100–£300. Some lenders waive it. Always get the answer in writing.
Can I keep my UK residential mortgage forever while renting it out?+
Almost never. Consent to Let is a temporary permission. If you let long-term, your lender will expect you to switch to a Buy-to-Let product.
What happens to my fixed rate if I switch?+
You'll typically pay an early repayment charge unless you're at the end of your fixed term. This is often the deciding factor in timing the move.
Can I get a new UK mortgage once I'm living abroad?+
Yes, through specialist expat lenders. Rates are higher and deposits larger, but the products do exist.
