Common Mistakes Overseas Investors Make (And How to Avoid Them)
Most of the money lost by overseas buyers is lost on the same handful of ordinary errors, and almost all of them happen before contracts are exchanged.
The expensive mistakes aren’t exotic. Nobody loses money on an obscure clause in a lease. They lose it by paying too much, trusting someone who is paid by the seller, and budgeting for a gross yield that never arrives net. Here are the ones I see most often and what to do instead.
1. Treating the asking price as the value
UK asking prices are opinions, and in slower markets they’re optimistic opinions. 23 Beech Grove was first listed at £125,000. It was reduced to £109,500. My client bought it at £90,000, which is 28% below the original figure. Nothing about the house changed in that time.
Instead: get sold comparables from the last six to twelve months on the same street type, and ask why the property is still on the market. Time on market is one of the most useful numbers in a negotiation and it’s rarely volunteered.
2. Taking advice from the person paid by the seller
The estate agent showing you round works for the vendor and is paid a percentage of what you pay. They aren’t being dishonest by talking the property up, they’re doing the job they’re paid for. The mistake is treating their view as neutral.
Instead: have someone on your side of the table whose fee doesn’t come from the seller, and ask any sourcer or agent directly whether anyone other than you is paying them on this transaction. Get the answer in writing.
3. A fee that rises with the price you pay
A sourcer on a percentage of purchase price is worse off every time they negotiate you a discount. That conflict doesn’t need bad intent to cost you money, it just needs a tired negotiator on a Friday afternoon.
Instead: fixed fee, agreed before work starts, staged so most of it depends on completion. Mine is set out in full, including the parts that aren’t in my favour.
4. Buying the yield without buying the demand
A high yield can mean a cheap house in a street with strong rental demand, or it can mean a cheap house nobody wants to live in. The number looks identical on a spreadsheet.
Instead: before you offer, get a letting agent who isn’t selling you the property to tell you what it would actually rent for and how long it would take to let. Then check the street on foot, or have someone check it for you and film both directions, not just the front elevation.
5. Forgetting that tax comes out of the rent at source
If you live abroad for six months or more a year, your letting agent must deduct basic rate income tax from your rent and pay it to HMRC, unless HMRC has approved you to receive it gross. Individual landlords apply on form NRL1i. If there is no agent and the tenant pays you over £100 a week, the tenant operates the scheme instead.

People model their cashflow on the gross rent and are then surprised by a fifth of it going missing. Apply early rather than reclaiming later.
6. Underbudgeting the purchase costs
Non-UK residents pay stamp duty at rates 2 percentage points above the UK resident rates on residential property in England and Northern Ireland, in place since 1 April 2021, on top of any other rates that apply. It can be reclaimed if you go on to spend 183 days in the UK in a continuous 365 day period within two years. Checked on GOV.UK on 25 August 2026: rates of stamp duty land tax for non-UK residents.
Other stamp duty rates change from budget to budget, so ask your solicitor for a calculation on your specific purchase rather than relying on any figure you read online. Then add the solicitor, searches, survey, lender fees and the cost of getting the property lettable.
7. Skipping the survey because there is a mortgage valuation
A lender’s valuation protects the lender. It isn’t a condition report and it won’t tell you the roof has two years left.
Instead: commission your own survey, read it yourself, and price the work before you exchange. A survey that stops you buying has paid for itself several times over.
8. Ignoring the EPC
You cannot let a property with an EPC below band E unless a valid exemption is registered, and the improvement spending cap is £3,500 including VAT. Government has stated an aim of moving as many private rented homes as possible to band C by 2030, though as of the guidance we checked that remains an aim rather than a dated legal requirement. Checked on GOV.UK on 25 August 2026: minimum energy efficiency standard landlord guidance.
A cheap house with a G rating and solid walls isn’t cheap. Get the current rating and a realistic view of what improving it costs, before you offer.
9. Buying through an overseas company and forgetting the register
An entity formed outside the UK that owns UK land must register on the Register of Overseas Entities at Companies House and disclose its beneficial owners. If it does not, it faces restrictions on buying, selling, transferring, leasing or charging the property, and non-compliance can carry a fine or a prison sentence. Checked on GOV.UK on 25 August 2026: register an overseas entity.
This one is entirely avoidable and it only bites when you try to sell, which is the worst moment to discover it.
10. Assuming it will be quick
My fastest conveyance was six weeks. That’s the fastest, not the average. At 55 Hunt Lane the offer was accepted on 16 July 2024 and completion was 28 October 2024, on a cash purchase with no chain.
And deals fail. I’ve sourced 16 properties and not every one of them completed, for reasons outside my control, because nothing is binding in England until exchange. Anyone quoting you a 100% success rate is either new or not counting properly.
11. Instructing a firm you have not checked
Property sourcing attracts people with a website and no supervision. Before money moves, check that the firm is supervised by HMRC for anti money laundering, belongs to a redress scheme, and holds professional indemnity insurance. Ask for the registration numbers and verify them on the registers themselves rather than trusting a badge on a page. Ours are on compliance.
12. Sending money on emailed instructions
Conveyancing fraud is real and it works by intercepting an email and changing the bank details at the last minute. Confirm your solicitor’s account details by telephone, on a number you obtained independently, and never act on a change of details sent by email.
What to do next
Work backwards. Decide what the money is for, then set the criteria, then look at property, in that order. Two pages worth reading before you start: five questions to ask before buying, which are the questions to put to whoever is selling you the deal, and what documents overseas buyers need, which is what to have ready so the checks don’t slow you down.
Nothing here’s tax or legal advice. Your position depends on where you’re resident and how you hold the property, so take it to a solicitor and an accountant.
