In short: a deposit of £125,000 to £300,000 is 25% of £500,000 to £1,200,000 of property. As £200,000 flats, that is two to six properties 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, and one lender alone will not fund all of it. The second is that the sum you need in cash for the 8% supplement runs to tens of thousands of pounds.
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 flats at £200,000 need £268,400 in cash before fees: the deposit, £4,400 of transaction tax and £64,000 of supplement.
- 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 and will not lend if you hold more than ten buy-to-lets.
- 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 | Supplement | Cash to find before fees |
|---|---|---|---|---|---|
| £125,000 | £500,000 | 2 at £250,000 | £4,200 | £40,000 | £169,200 |
| £150,000 | £600,000 | 3 at £200,000 | £3,300 | £48,000 | £201,300 |
| £200,000 | £800,000 | 4 at £200,000 | £4,400 | £64,000 | £268,400 |
| £300,000 | £1,200,000 | 6 at £200,000 | £6,600 | £96,000 | £402,600 |
The split uses £200,000 flats 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. A £250,000 flat carries a £187,500 loan. Tax columns are totals across the purchases. Separate purchases from different sellers are assumed. 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 flat 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, and does not lend in Scotland.
So six flats at 75% borrowing needs more than one 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.
So on the three sets of criteria here, an EU national living in the EU, a Maltese investor in Malta for example, has no route to a mortgage on a Scottish property: Skipton International does not take EU residents, West One takes EEA nationals only if they live in the UK, and Molo, which does accept EU residents, lends only in England and Wales. HSBC UK's list of eligible countries has no EU member state on it.
Other lenders may differ. 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 Greater Glasgow is £1,089 a month, and in Lothian £1,324. So at full 75% borrowing on a £200,000 flat, the average Glasgow two-bedroom rent falls just short on the tougher test and passes with room on a five-year fix. The table turns the question round: how large a loan does the average rent support?
| Rental 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% |
|---|---|---|---|---|
| Greater Glasgow | £1,089 | £1,340 | £144,400 | £201,400 |
| Lothian | £1,324 | £1,703 | £175,600 | £244,900 |
| West Lothian | £836 | £1,103 | £110,900 | £154,600 |
| South Lanarkshire | £741 | £976 | £98,300 | £137,100 |
| Fife | £738 | £968 | £97,900 | £136,500 |
| Aberdeen and Shire | £776 | £965 | £102,900 | £143,500 |
| Dundee and Angus | £750 | £984 | £99,400 | £138,700 |
ONS average rents by rental area, August 2026, mostly advertised new lets. Loan sizes assume rental cover of 125% and are rounded to the nearest £100. An average is not a valuation of any flat.
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 flat by flat, on the rent each one can show.
Spreading it, and running it
- Concentration. Skipton International's limit of three flats in one postcode district is one lender's view of how much to hold in one place. Rent controls, if they come, will be set area by area. See our guide to Scotland's rent controls.
- Management. Four to six tenancies in another country is a job. Our guide to self-managing or using an agent sets out the trade-off.
- Records. Six flats 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 flats at 75% borrowing | More than one lender, and rent that passes each test | The most debt. Every loan is tested again when its fix ends |
| Fewer flats, 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 flats carry debt | More moving parts. Cash flats can be borrowed against later, at the lender's terms then |
What comes with a Scottish let
- Purchase tax is Land and Buildings Transaction Tax, plus the 8% Additional Dwelling Supplement if you already own a home anywhere in the world. Scotland has no separate surcharge for non-residents. Our stamp duty guide for non-resident buyers sets out how England differs.
- You must register as a landlord with the council before you let, and renew every three years. Letting without registration is a criminal offence with a fine of up to £50,000.
- A tenancy deposit can be up to two months' rent and must be protected in one of three approved schemes.
- 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.
- Every owner registers as a landlord, and each property is listed on the registration.

Common questions
What is a portfolio landlord?
Lenders use the term for someone with four or more mortgaged buy-to-let properties. Skipton International and Molo both publish that definition. A portfolio landlord is assessed on the whole portfolio as well as the property being bought.
How many buy-to-let mortgages can a non-UK resident have?
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.
How much cash do I need to buy four £200,000 flats in Scotland?
With a 25% deposit on each, the deposits come to £200,000. Land and Buildings Transaction Tax is £1,100 on each flat, and the 8% Additional Dwelling Supplement is £16,000 on each if you own a home elsewhere. That makes £268,400 before legal, survey and lender fees.
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.
