Property and moving abroad:
the complete FX guide.

Buying property abroad, selling an overseas home, or emigrating all involve transferring large sums of money across borders. These are often the largest financial transactions people make outside of their careers - and they are the transactions where the exchange rate matters most and where banks profit most.

A 3% bank margin on a £100,000 holiday purchase is inconvenient. A 3% margin on a £500,000 property purchase is £15,000. On a £300,000 emigration transfer it is £9,000. These are not edge cases - they are the standard cost of using a high street bank for large personal international transfers.

The currency risk in an overseas property purchase typically runs from the moment you agree a price to the day you complete. Between those two points - which can be weeks, months, or in some markets over a year - exchange rates can move significantly.

Reservation fee. Usually a small amount (1-5% of the purchase price) paid at the point of agreeing the purchase to take the property off the market. Often payable quickly, so the rate at time of payment matters.

Deposit. Typically 10-30% of the purchase price, paid at exchange of contracts or equivalent legal stage. This is usually the first large currency exposure.

Completion balance. The remaining purchase price paid on the day you become the legal owner. This is where forward contracts are most valuable - you can fix the rate for this payment months in advance.

In some markets (particularly parts of Spain, France, and Portugal popular with UK buyers), properties are sometimes quoted in sterling as a convenience. This doesn't eliminate the currency risk - the developer or agent still has to convert, and the rate they embed in the sterling price includes their own margin.

When you sell an overseas property and repatriate the proceeds to the UK, the same dynamics apply in reverse. You want to convert your euros, dollars, or other currency back into sterling at the best possible rate.

You may have some flexibility over when you convert after a sale completes. If you believe the rate will improve in the near term, you could hold the funds in a foreign currency account and convert later. If you want certainty, you can agree a rate in advance.

When repatriating proceeds from an overseas property sale, the conversion itself does not typically create a separate tax liability in the UK - but the gain on the property sale may be subject to UK Capital Gains Tax regardless of where the property is located, and foreign exchange gains on currencies can in some circumstances be taxable. Seek independent tax advice specific to your situation.

Emigration typically involves transferring a much larger and more varied pool of assets than a property purchase - savings, pension funds (in some cases), proceeds from selling a UK home, redundancy payments, and ongoing income that may continue to arrive in sterling for some time after you leave.

You don't need to transfer everything at once. Many emigrants move funds in stages - transferring an initial amount to set up in the new country, then moving more as UK assets are sold or UK accounts are wound down. This can be advantageous if you want to average your exchange rate across different market conditions.

If you continue to receive sterling income after emigrating - a UK pension, rental income from a UK property you are retaining, or contract income - you will need a reliable, cost-effective way to convert this regularly. A standing arrangement with an FX broker is usually far cheaper than allowing your overseas bank to convert incoming sterling.

UK State Pension and most private pensions can be paid directly into an overseas bank account. However, the conversion will typically be performed by your pension provider or their bank at a retail rate. Many pension recipients convert at a far better rate by having their pension paid into a UK account and transferring separately.

A forward contract is an agreement to exchange a fixed amount of currency at a pre-agreed rate on a future date. For property buyers and emigrants, it is the most important risk management tool available.

You identify the amount you need to transfer and the date by which you need it to arrive. You agree a rate with your FX broker today (close to the current spot rate, adjusted slightly for the forward period). You pay a small deposit, typically 5-10% of the total. On the agreed date, you pay the balance and the transfer is made at the pre-agreed rate.

The rate you lock will be slightly different from the spot rate - it will reflect the interest rate differential between the two currencies over the forward period. This is a standard, transparent adjustment - not an additional fee.

Forward contracts are most valuable when you have a fixed, known obligation in a foreign currency at a specific future date - a property completion, a school fees payment, a tax liability. They are less useful for discretionary or uncertain payments where flexibility matters more than certainty.

Whether you are buying, selling, or emigrating, the following steps apply:
