Buying a rental property in Scotland is not the same as buying one in England. The tax is different, the tenancy regime is different, the purchase process is different, and the landlord obligations are stricter. I have built my own portfolio here and advise landlords across Renfrewshire, Paisley and Lanarkshire, so this guide covers what actually matters before you commit.
What you need to get started
| Requirement | Typical position |
|---|---|
| Deposit | 25% is standard; a few lenders accept 20% at a higher rate |
| Minimum income | Commonly £25,000, though some lenders have no minimum |
| Age | Usually 21+ at application, often up to 75–85 at term end |
| Own your own home? | Many lenders require it; some accept first-time landlords who rent |
| Rental cover | Typically 125–145% of the mortgage interest at a stressed rate |
| Repayment type | Interest-only is normal for buy to let, unlike residential |
The rental stress test decides how much you can borrow
This is the single most misunderstood part of buy to let, and it catches people out constantly. Your borrowing is not primarily driven by your income. It is driven by the rent the property will achieve.
Lenders apply an interest coverage ratio: the projected rent must cover a set percentage of the mortgage interest, calculated at a stressed rate rather than the rate you will actually pay. A basic-rate taxpayer is commonly assessed at 125%, a higher-rate taxpayer at 145%, and the stressed rate is often around 5.5% or your product rate plus 2%, whichever is higher.
On a property in Paisley renting at £750 a month, a 145% requirement at a 5.5% stress rate supports roughly £112,000 of borrowing. At 125% the same rent supports around £130,000. Which bracket you fall into can change your purchase price by twenty thousand pounds — which is why lender selection matters so much here.
ADS: the 8% that catches people out
The Additional Dwelling Supplement is Scotland's surcharge on additional residential property. For transactions on or after 5 December 2024 it is 8%, and it applies where the price is £40,000 or more.
The critical detail is that ADS is charged on the entire purchase price, not just the portion above a threshold. On a £150,000 flat that is £12,000, payable on top of any standard LBTT. This is not a cost you can add to the mortgage — it must come from your own funds at settlement, alongside your deposit and legal fees.
| Purchase price | Standard LBTT | ADS at 8% | Total tax |
|---|---|---|---|
| £100,000 | £0 | £8,000 | £8,000 |
| £150,000 | £100 | £12,000 | £12,100 |
| £200,000 | £1,100 | £16,000 | £17,100 |
| £250,000 | £2,100 | £20,000 | £22,100 |
If you are replacing your main residence rather than adding a property, you may be able to reclaim the ADS — for transactions on or after 1 April 2024 the relevant window is 36 months. Your solicitor should confirm whether you qualify.
Your legal obligations as a Scottish landlord
Scotland regulates the private rented sector more tightly than England, and lenders expect you to be compliant.
- Landlord registration — you must register with the local council before letting, and renew every three years. Letting without registering is a criminal offence.
- Private Residential Tenancy — since December 2017 almost all new tenancies are PRTs. They are open-ended, there is no fixed end date, and you can only recover possession using one of the statutory grounds through the First-tier Tribunal.
- Repairing Standard — the property must meet a legal condition standard covering structure, installations, heating, safety and more.
- Safety certificates — annual gas safety check, electrical installation condition report every five years, working smoke and heat alarms to the Scottish standard, and a legionella risk assessment.
- Deposit protection — tenancy deposits must be lodged with an approved Scottish scheme within 30 working days.
- Rent increases — no more than once every 12 months, using the correct statutory notice.
Rent controls: where things stand
The Housing (Scotland) Act 2025 created a framework for rent control areas, but they are not currently in force. From 1 April 2026 local authorities must begin assessing rent conditions in their areas, with the first reports due to Scottish Ministers by 31 May 2027. Only after that can Ministers designate a rent control area, and only where they judge it necessary and proportionate.
Where an area is designated, increases would be capped at CPI plus 1%, to a maximum of 6%, applying both during and between tenancies, with designations lasting up to five years. Certain properties — including new-build and build-to-rent — are expected to be exempt. This is a moving area of policy, so check the current position before making assumptions about future rent growth.
Making the numbers work
A realistic appraisal on a £150,000 flat in Renfrew with a 25% deposit:
| Item | Amount |
|---|---|
| Deposit (25%) | £37,500 |
| ADS at 8% | £12,000 |
| LBTT | £100 |
| Legal fees and searches | ~£1,200 |
| Cash needed at settlement | ~£50,800 |
| Monthly rent | £750 |
| Mortgage interest (£112,500 at 5.2%) | £488 |
| Letting agent, insurance, maintenance allowance | ~£150 |
| Monthly surplus before tax | ~£112 |
That is before income tax on the rental profit and before void periods. Buy to let in Scotland works, but it works on a longer view than the headline yield suggests — and the ADS means your cash requirement is far higher than the deposit alone.
Common questions
This guide is general information, not regulated financial advice, and reflects our understanding of the rules at the date shown. Tax treatment depends on individual circumstances and may change. Your home may be repossessed if you do not keep up repayments on your mortgage. Not all buy to let mortgages are regulated by the Financial Conduct Authority.
