Every year real estate agents see it happen: a buyer negotiates hard on the purchase price, saves a few thousand euros through good negotiation, and then loses several times that amount on a bad exchange rate simply because they didn't think about the currency transfer until the last minute — often right after finally getting their Portuguese bank account sorted, or their mortgage approved. This is one of the most overlooked parts of buying abroad, and it's also one of the easiest to get right if you plan for it early.
Why does it matter so much on a property purchase?
Because the sums involved are large enough that even a small difference in exchange rate translates into real money. On a six-figure transfer, a rate that's even half a percent worse than it needed to be can cost you thousands — often more than any fee you were trying to avoid by using your regular bank. The goal isn't to time the market perfectly; it's to avoid the two most common ways buyers lose money without realising it.
Bank or currency specialist — does it actually make a difference?
Usually, yes, and more than people expect. Banks tend to build their margin directly into the exchange rate rather than charging it as a visible fee, so you often convert at whatever rate applies on the day you instruct the payment, with the true cost hidden in the spread rather than an itemised charge. Currency specialists compete on rate rather than convenience, which generally means tighter spreads, an all-in rate quoted upfront so you know the real cost before you commit, and — for property purchases specifically — a dedicated contact who understands your timeline and can make sure funds land exactly when your lawyer or notary needs them.
The comparison that actually matters isn't the advertised fee on either side — it's the total amount of your home currency it costs you to end up with the euros you need. On a property-sized transfer, it's worth getting a comparative quote from at least one currency specialist alongside your bank before you commit to either.
What's a forward contract, and do I need one?
A forward contract lets you lock in today's exchange rate for a transfer that won't actually happen for weeks or months — useful if you've agreed a purchase price and want the number you budgeted at exchange of promissory contract to be the number you actually pay at completion, regardless of what the market does in between. The trade-off is straightforward: you give up any upside if rates move in your favour, in exchange for protection if they move against you. For a purchase with a real completion date on the calendar, that certainty is usually worth more than the small chance of a better rate later.
For your deposit specifically, you may want to move quickly with a straightforward transfer at the current rate; for the larger completion payment further down the line, a forward contract or a rate alert gives you more control over timing.
What should I actually do, practically?
Start the conversation early — ideally as soon as you've agreed a price, not the week of completion. This gives you the option of a forward contract or watching for a better rate, rather than being forced to transfer whatever the rate happens to be that day.
Get quotes from more than one provider — your bank and at least one currency specialist — and compare the actual amount that arrives in euros, not just the headline fee.
Ask about forward contracts and rate alerts if your completion date is more than a few weeks out — these are standard tools most currency specialists offer, not a premium extra.
Confirm who's paying any receiving-bank fees on the Portuguese side, so the full amount you expect actually lands with your lawyer or notary.
Never send funds based on instructions received by email alone — bank details for large transfers should always be confirmed by phone with your lawyer or the receiving party, since payment-redirection fraud targeting property buyers is a real and growing risk internationally.
That last point is worth taking seriously. It's not really a currency-exchange issue so much as a security one, but it belongs in the same conversation, since it happens at exactly this stage of a purchase — right around the same time you're finalising costs covered in our guide to the real cost of buying property in the Algarve.
FAQ
Is it cheaper to use a currency specialist instead of my bank to buy property in Portugal? Often, yes, particularly on larger, property-sized transfers, because banks tend to build their margin into the exchange rate rather than showing it as a separate fee. Getting a comparative quote from both before you commit is the only way to know for certain in your specific case.
What is a forward contract and should I use one? A forward contract lets you lock in today's exchange rate for a transfer happening at a future date, which is useful for matching the price you budgeted with what you actually pay at completion. It's most useful when you have a firm completion date and want certainty over the possibility of a better rate later.
How do I avoid currency transfer scams when buying property abroad? Always confirm bank transfer details by phone with your lawyer or the receiving party before sending funds — never rely solely on bank details received by email, since these can be intercepted and altered by fraudsters. This is especially important around completion, when large sums are moving.
When should I start thinking about currency transfer for a property purchase? As early as possible — ideally as soon as you've agreed a price — so you have time to compare providers, consider a forward contract if your completion date is weeks or months away, and avoid being forced to transfer at whatever rate happens to apply on the day you need the funds to move.
