In short: a deposit of £30,000 to £60,000 is 25% of a property worth £120,000 to £240,000. That reaches the average flat in Cardiff, at £161,000, and the average terraced house in Swansea, Newport and Rhondda Cynon Taf. Land Transaction Tax at the higher rates runs from £6,000 to £14,100 across the band if you already own a home anywhere in the world. Molo and West One lend at every point in it. At £50,000 a third lender comes in: a £200,000 property and a £150,000 loan are the smallest Skipton International will take. What then decides the loan is whether the rent covers the interest with room to spare, and on Welsh terraced houses that test is tight.
Read this first
This guide is education, not personal advice. It shows how the sums work for someone who lives outside the UK, using published tax rates, lender criteria and average prices on the dates shown. It does not know your income, your tax position or your plans, and it is not a recommendation to buy. We are not financial advisers, mortgage brokers or tax advisers. Nothing here promises a rent, a yield or a loan.
The 30-second version
- A deposit of £30,000 to £60,000 is 25% of £120,000 to £240,000.
- Cash to find with transaction tax, if you own a home elsewhere: £36,000 to £74,100 before fees.
- £50,000 is a threshold: it meets Skipton International's smallest loan and smallest property. Skipton does not take EU residents. Molo does.
- On ONS averages a Cardiff flat needs £911 a month to pass a 7.24% test. The average flat rent in Cardiff is £995.
- Of the seven averages below, only the Cardiff flat passes at 7.24%. All seven pass at 5.19%. The product you choose changes the answer.
What the deposit buys on paper
| Deposit | Property at 25% | Loan | Transaction tax if you own a home elsewhere | Transaction tax if you own no other home | Cash to find before fees |
|---|---|---|---|---|---|
| £30,000 | £120,000 | £90,000 | £6,000 | £0 | £36,000 |
| £45,000 | £180,000 | £135,000 | £9,000 | £0 | £54,000 |
| £50,000 | £200,000 | £150,000 | £10,700 | £0 | £60,700 |
| £60,000 | £240,000 | £180,000 | £14,100 | £900 | £74,100 |
Cash to find is the deposit plus the tax for a buyer who already owns a home elsewhere. Both tax columns are for a buyer who lives outside the UK.
Land Transaction Tax is charged in slices. Wales has no surcharge for buyers who live abroad. What matters is whether you already own a home, in Wales or anywhere else in the world. If you do, the higher rates apply: 5% up to £180,000, 8.5% from there to £250,000, 10% to £400,000 and 12.5% to £750,000. If you own no other property, the main rates apply and there is nothing to pay below £225,000. A company always pays the higher rates.
Legal fees, the survey, the lender's fee and any work the property needs come on top. Get quotes before you fix a budget.
Will a lender fund it?
Three lenders are not the whole market, and criteria change often. HSBC UK, for one, also lends to non-UK residents, but only to residents of 14 listed countries and regions, none of them in the EU, with income of £50,000 or more and a deposit of at least 25%, or 40% above £1 million. We are not mortgage brokers. Use this as a picture of how the rules look, then ask a broker who handles non-resident cases.
Read against this band:
- £30,000 or £45,000 deposit. Loans of £90,000 and £135,000. Both fit Molo on size, and West One for an expat with a UK credit record and a UK buy-to-let already. Both are under Skipton International's £150,000 minimum.
- £50,000 deposit. A £200,000 property and a £150,000 loan meet Skipton International's minimums too. It also wants income of £50,000 or more for a sole employed applicant, a home outside the EU, and an energy rating of A to C, or D with the potential to reach C.
- £60,000 deposit. A £240,000 property and a £180,000 loan fit all three on size.
If you live in the EU
From 11 January 2027 an EU rule known as CRD VI stops banks based outside the EU from lending to customers in the EU unless they have a licensed branch there. Loans agreed before 11 July 2026 are protected. Skipton International has already stopped taking applications from EU residents, and HSBC UK's list of eligible countries has no EU member state on it.
Molo is the exception among the criteria here. Its guide dated 23 September 2026 lists European Union countries among those it accepts, for property in England or Wales only. So an EU national living in the EU, a Maltese investor in Malta for example, has a published route to a mortgage on a Welsh property. The same criteria give no such route in Scotland, as our Scottish guide for the same deposit shows.
That can change. Lenders that are not banks may fall outside the rule, there is a narrow exemption where the customer approaches the lender entirely on their own initiative, and each member state writes its own version. Malta had not finalised its law as of mid 2026. Ask a broker which lenders will still take your application before you plan around a mortgage.
Does the rent carry the loan?
A lender looks at more than you. It tests the rent. Skipton International publishes its test: the rent must be 125% of the interest. On a five-year fix it tests at the rate you pay, from 5.19% on 2 October 2026. On other products it tests at 7.24%. Molo's guide does not print its test and points brokers to a calculator, so its rate appears here as interest only.
Here is that test on the average Cardiff flat, with a 25% deposit of £40,250.
On averages the Cardiff flat passes both tests. Interest alone would be £522 a month at 5.19% and £663 at Molo's 6.59%, before letting fees, insurance, repairs, empty months and tax. A £120,750 loan is under Skipton International's minimum, so the pass only matters if another lender takes the case. Our guide to the buy-to-let stress test explains the method.
Where £120,000 to £240,000 sits across Wales
In much of Wales the average flat costs less than this band, so the table mixes Cardiff and Vale of Glamorgan flats with terraced houses elsewhere.
| Area and property type | Average price | Average rent a month | A year's rent as a share of price | Rent a lender wants at 7.24% | Rent a lender wants at 5.19% |
|---|---|---|---|---|---|
| Cardiff, flats | £161,000 | £995 | 7.4% | £911 | £653 |
| Vale of Glamorgan, flats | £156,000 | £806 | 6.2% | £882 | £633 |
| Rhondda Cynon Taf, terraced houses | £143,000 | £733 | 6.2% | £809 | £580 |
| Wrexham, terraced houses | £160,000 | £731 | 5.5% | £905 | £649 |
| Swansea, terraced houses | £169,000 | £824 | 5.9% | £956 | £685 |
| Newport, terraced houses | £190,000 | £922 | 5.8% | £1,075 | £770 |
| Cardiff, terraced houses | £262,000 | £1,177 | 5.4% | £1,482 | £1,062 |
Prices and rents are ONS averages for each council area and property type: prices for July 2026, private rents for August 2026. A real property will differ from an average. The last two columns assume a loan of 75% of the average price and rental cover of 125%, which is Skipton International's published test. The share-of-price column divides one average by another. It is not a forecast of what any property will earn.
The Cardiff terraced house sits just above the band and is shown for comparison. On these averages only the Cardiff flat clears the 7.24% test. The Vale of Glamorgan flat and the five terraced houses fall short of it, and all seven clear 5.19%. Where the rent falls short, a lender lends less, and the gap is filled by a bigger deposit.
Three routes people take at this level
None of these is a recommendation. Which one fits depends on facts this page does not have.
| Route | What it needs | What can go wrong |
|---|---|---|
| One property at 75% borrowing | A lender for your country and income, and rent that passes its test | The largest loan means the largest interest bill. A rate rise at the end of a fix lands on a thin margin |
| One property with a bigger deposit | A deposit of 35% to 40% instead of 25% | More of your cash sits in one property. A cheaper property, or a longer wait |
| Wait and buy for cash | £90,300 for the average flat in Rhondda Cynon Taf with transaction tax, more elsewhere | No borrowing means no lender test, and no gearing either. Prices and rules move while you save |
What comes with a Welsh let
- Purchase tax is Land Transaction Tax. The higher rates apply if you already own a home in Wales or anywhere else in the world, and to every company purchase of £40,000 or more. Wales has no separate surcharge for non-residents.
- Every landlord registers with Rent Smart Wales. It costs £60 online and lasts five years. Failing to register is an offence.
- If you let or manage the property yourself you also need a Rent Smart Wales licence, which comes with training. If you do not, you must appoint a licensed agent.
- Tenants in Wales are called contract-holders. You must give them a written statement of the occupation contract within 14 days of the start.
- A no-fault notice must give at least six months, cannot be served in the first six months, and cannot be given unless you have met the Rent Smart Wales and deposit rules.
- A deposit must be protected in an approved scheme within 30 days.
- Your letting agent or tenant takes basic rate tax off the rent before paying you, unless HMRC approves you to receive it gross. See our guide to the Non-Resident Landlord Scheme.
- When you sell, you must report the sale to HMRC within 60 days, even if there is no tax to pay.
This guide is general education for people who live outside the UK. It is not personal, financial, mortgage, tax or legal advice, and it is not a recommendation to buy any property. Tax rates, lender criteria and prices change. Take regulated advice in the UK and in your country of residence before you commit money.
Common questions
How much deposit does a non-UK resident need for a buy-to-let mortgage in Wales?
It depends on the lender. On the criteria we read on 2 October 2026, Molo lends from £45,000 on a property worth £75,000 or more, which is a deposit from £18,750 at 75% borrowing, and it accepts EU residents. West One lends from £50,000 to expats who already own a UK buy-to-let. Skipton International starts at a £150,000 loan on a £200,000 property, which is a £50,000 deposit, and does not accept EU residents.
Does the average rent in Cardiff cover a 75% buy-to-let loan?
On ONS averages, yes for a flat. The average Cardiff flat was £161,000 in July 2026, so a 75% loan is £120,750. With rental cover of 125% a lender testing at 7.24% wants £911 a month, and the average flat rent in August 2026 was £995. The average terraced house does not pass at 7.24% and does pass at a 5.19% pay rate.
How much Land Transaction Tax is there on a £180,000 buy-to-let in Wales?
£9,000 if you already own a home in Wales or anywhere else in the world, which is the 5% higher rate. If you own no other property there is nothing to pay, because the main rates start at £225,000. Wales has no surcharge for non-residents.
Is this guide advice on what I should buy?
No. It is general education using published tax rates, lender criteria and average prices. It is not personal, financial, mortgage or tax advice, and it does not take your circumstances into account.
