In short: a deposit of £125,000 to £300,000 is 25% of £500,000 to £1,200,000 of property. As £200,000 properties, that is two to six of them and a real portfolio. Two things change at this level. Lenders treat you as a portfolio landlord from the fourth mortgage and look at every loan you hold. The second is that the average Welsh two-bedroom rent falls short of the tougher lender test on a £200,000 property in every area in the table below, so the rent decides more than the price does.
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 £125,000 to £300,000 is 25% of £500,000 to £1,200,000.
- Four properties at £200,000 need £242,800 in cash before fees if you own a home elsewhere: the deposit and £42,800 of transaction tax.
- Four or more mortgaged buy-to-lets make you a portfolio landlord. Lenders then test the whole portfolio.
- Skipton International funds five properties at most. Molo caps one customer at £5 million of borrowing and accepts EU residents.
- A £150,000 loan needs rent of about £1,131 a month at a 7.24% test, or £811 at 5.19%.
What the deposit buys on paper
| Deposit | Buying power at 25% | Example split | Transaction tax in total | Cash to find before fees |
|---|---|---|---|---|
| £125,000 | £500,000 | 2 at £250,000 | £29,900 | £154,900 |
| £150,000 | £600,000 | 3 at £200,000 | £32,100 | £182,100 |
| £200,000 | £800,000 | 4 at £200,000 | £42,800 | £242,800 |
| £300,000 | £1,200,000 | 6 at £200,000 | £64,200 | £364,200 |
The split uses £200,000 properties because that is the smallest property, with the smallest loan of £150,000, that Skipton International will lend on to someone living outside the UK. In Wales that is above the average terraced house in every council area except Cardiff, Monmouthshire and the Vale of Glamorgan. Molo and West One lend on smaller properties. A £250,000 property carries a £187,500 loan. Transaction tax is for a buyer who lives outside the UK and already owns a home elsewhere, on separate purchases from different sellers. Legal, survey and lender fees are extra on every purchase.
The fourth mortgage changes how lenders see you
Skipton International and Molo both define a portfolio landlord as someone with four or more mortgaged buy-to-lets. From that point the lender looks past the property you are buying.
- Skipton International funds at most five properties for one borrower, will not lend if you hold more than ten buy-to-lets in total, and allows three in one postcode district. It checks rental cover on all your buy-to-let borrowing, wherever it is held.
- West One does not limit how many properties you hold with other lenders, but the portfolio must pay for itself. It lends up to £1 million to an expat or foreign national on standard terms.
- Molo caps what one customer can borrow at £5 million. A borrower buying more than four properties may be asked to show more than 12 months as a landlord.
So six properties at 75% borrowing is beyond Skipton International alone. It needs a second lender, or less borrowing.
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.
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.
What the rent has to do
The average two-bedroom rent in Cardiff is £1,085 a month, in Newport £863 and in Swansea £797. So at full 75% borrowing on a £200,000 property, the Cardiff and Newport averages fall short of the tougher test and pass on a five-year fix. The Swansea average falls short of both. The table turns the question round: how large a loan does the average rent support?
| Council area | Average two-bedroom rent | Average three-bedroom rent | Largest loan a two-bedroom rent supports at 7.24% | Largest loan it supports at 5.19% |
|---|---|---|---|---|
| Cardiff | £1,085 | £1,211 | £143,900 | £200,700 |
| Vale of Glamorgan | £888 | £997 | £117,700 | £164,300 |
| Newport | £863 | £965 | £114,400 | £159,600 |
| Swansea | £797 | £897 | £105,700 | £147,400 |
| Wrexham | £711 | £840 | £94,300 | £131,500 |
| Bridgend | £701 | £816 | £93,000 | £129,700 |
| Rhondda Cynon Taf | £675 | £758 | £89,500 | £124,900 |
ONS average private rents by council area, August 2026. Loan sizes assume rental cover of 125%, which is Skipton International's published test, and are rounded to the nearest £100. An average is not a valuation of any property.
Where the rent supports less than 75% of the price, the lender lends less and the deposit grows. That is why a portfolio plan is built property by property, on the rent each one can show.
Spreading it, and running it
- Concentration. Skipton International's limit of three properties in one postcode district is one lender's view of how much to hold in one place.
- Management. In Wales this is a legal point as well as a practical one. Unless you hold a Rent Smart Wales licence yourself, a licensed agent must let and manage every property. Our guide to self-managing or using an agent sets out the trade-off.
- Records. Six properties at about £1,000 a month is £72,000 of rent a year, above the Making Tax Digital threshold. See Making Tax Digital for landlords.
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 |
|---|---|---|
| Several properties at 75% borrowing | More than one lender in most cases, and rent that passes each test | The most debt. Every loan is tested again when its fix ends |
| Fewer properties, lower borrowing | A deposit of 40% to 50% on each | Less property for the same cash. Easier tests, lower interest |
| A mix: some bought for cash, some borrowed | A plan for which properties carry debt | More moving parts. Cash purchases can be borrowed against later, at the lender's terms then |
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.

Common questions
How many buy-to-let mortgages can a non-UK resident have in Wales?
It depends on the lender. On the criteria we read on 2 October 2026, Skipton International funds a maximum of five properties for one borrower and will not lend to someone with more than ten buy-to-lets in total. West One sets no limit on properties held with other lenders but requires the portfolio to pay for itself. Molo caps one customer at £5 million of borrowing. Skipton International and Molo both treat four or more mortgaged buy-to-lets as a portfolio.
How much cash do I need to buy four £200,000 properties in Wales from abroad?
With a 25% deposit on each, the deposits come to £200,000. If you already own a home anywhere in the world, Land Transaction Tax at the higher rates is £10,700 on each property. That makes £242,800 before legal, survey and lender fees.
Does the average rent in Cardiff support a 75% loan on a £200,000 property?
On ONS averages for August 2026, it depends on the test. A £150,000 loan with rental cover of 125% needs £1,131 a month at a 7.24% test and £811 at a 5.19% pay rate. The average two-bedroom rent in Cardiff was £1,085, which passes the second and falls short of the first. That is one lender's published test set against an average, and a real property will differ.
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.
