Why UK buyers reach for it
Since Brexit put British applicants into the third-country category, Greek lenders generally cap them well below what an EU resident can borrow, on a shorter term. Set against that, a UK homeowner with substantial equity often finds that raising the money at home is simpler, faster and available at a higher loan-to-value than anything a Greek bank will offer against a holiday property.
That reasoning is sound as far as it goes. The part worth slowing down for is what the choice does to your risk, because it is not a like-for-like swap.
The three routes, and how they differ
A remortgage replaces your existing UK mortgage with a larger one from a new or existing lender, releasing the difference as cash. It is usually the cheapest of the three if your current deal is ending anyway, because you are repricing the whole loan rather than adding an expensive slice. If you are locked into a fixed rate, early repayment charges can wipe out that advantage entirely, so the timing relative to your current deal matters more than the headline rate.
A further advance is additional borrowing from your existing lender, alongside the mortgage you already have. It leaves your current rate untouched, which is valuable if that rate is better than anything available today, and the additional slice is priced separately. It is generally quicker than a remortgage, but you are limited to one lender's appetite and criteria.
A second-charge loan comes from a different lender and sits behind your existing mortgage on the same property. It is the route most often used when the first mortgage is on a rate worth protecting and the existing lender will not extend further. It is typically priced above a first charge, reflecting its position in the queue if the property is ever sold in default.
All three are regulated borrowing secured on your home, and all three are assessed on UK affordability rules rather than on the Greek property.
How lenders view "buying abroad" as a purpose
UK lenders ask what the money is for, and the answer affects the outcome. Some are entirely comfortable with an overseas property purchase; others restrict the purpose, ask for more detail, or decline it. This varies by lender and by product, and it is not always visible in published criteria.
Affordability is assessed on your ability to service the increased UK borrowing, stress-tested at a higher rate than the one you are offered. Crucially, the Greek property does not help. Its value is not security for this loan, and any rental income you hope to earn from it will usually be discounted heavily or ignored altogether. You are borrowing more against your UK home on the strength of your UK income, and that is the whole of the test.
What the comparison actually looks like
It is tempting to compare the sterling rate with the euro rate and stop there. That is the wrong comparison, for two reasons.
The first is currency. Borrow in sterling and you convert a lump sum once, at whatever rate applies on the day, then repay in the currency you earn. Borrow in euros and you convert every monthly payment for the life of the loan, so the sterling cost of your mortgage moves with the exchange rate for twenty years. Neither is safe: the first concentrates your currency risk into a single moment, the second spreads it across the whole term. Which you prefer depends on your circumstances, not on which is cheaper today.
The second is what stands behind the debt. A Greek mortgage is secured on the Greek property. If the plan goes wrong, that is what is at risk. UK equity release secures the Greek purchase on your home in Britain, which is very likely the roof over your family. People underweight this because the paperwork feels routine and familiar, but it is the single most consequential difference between the two routes.
Cost, term and the thing people forget
Raising money over your remaining UK mortgage term can look inexpensive per month while costing considerably more in total interest than a shorter Greek loan would. Extending the term to keep payments comfortable quietly increases what you repay overall, and for buyers approaching retirement it can push borrowing past the point where a lender is willing to lend at all, or past the point where the income servicing it still exists.
Set against that, there are real savings. You avoid the Greek lender's arrangement fees, the mortgage-related portion of Greek purchase costs, the lender's valuation, and the requirement some Greek banks attach to hold accounts or take specified insurance cover. Buying without a Greek mortgage also removes a financing condition from the transaction, which can strengthen your position with a seller and shorten the timetable.
A combination is often the sensible answer rather than an all-or-nothing choice: enough UK equity to reach a comfortable deposit, with a smaller Greek loan covering the rest. That keeps some of the borrowing secured on the asset it paid for.
Before you release equity
- Check early repayment charges on your current deal before assuming a remortgage is cheapest.
- Ask your lender directly whether an overseas property purchase is an accepted purpose.
- Test affordability on the stressed rate, not the offered rate.
- Compare total interest over the full term, not the monthly payment.
- Check how the term interacts with your retirement date.
- Decide deliberately whether you want currency risk in one lump or spread across the term.
- Be clear that your UK home, not the Greek property, is the security.
- Price the combined route as well as the two pure ones.

This guide is general information, not personal financial, legal, tax or currency advice. Borrowing more against your home increases the debt secured on it. Think carefully before securing other debts against your home. Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it. Mortgage availability is subject to credit, income, valuation and lender criteria.
