A Scottish buy-to-let application is assessed against the lender’s own criteria, including borrower circumstances, deposit, property, experience and rental coverage. Budget for the purchase, ordinary LBTT, any applicable Additional Dwelling Supplement (ADS), finance, landlord setup and contingencies. Before letting, check registration, tenancy, repair and—separately—short-term-let rules. No approval, tax result or yield is promised.
What to check with the lender
Buy-to-let is an investment and borrowing decision, not a guaranteed route to home ownership. Eligibility, minimum deposit, maximum LTV, acceptable property, borrower age, income, portfolio size, personal ownership versus company ownership, rental calculation, stress rate, repayment type, fees and required experience are lender-specific and can change. A lender may use rent, personal income, or both, and may assess a vacant period or other commitments. A broker’s assessment is not an offer.
“Rental coverage” is also lender-specific. A lender may calculate interest coverage from rent and an assumed or stressed interest rate, with different treatment for tax status, repayment loans, fees, voids and property type. The worksheet below is arithmetic for a hypothetical property, not a lender calculation, affordability result, forecast or recommendation.
Deposit, eligibility and first-landlord preparation
Before an application, establish:
- Purpose and ownership: intended long let, short-term let or another use; individual, joint or company ownership; intended occupancy and exit plan. Do not assume that a residential buy-to-let mortgage permits short-term letting.
- Funds: deposit, source trail, ordinary LBTT, possible ADS, legal and registration costs, valuation, lender/broker fees, furnishing or safety setup and a contingency reserve. A deposit is not the whole cash requirement.
- Lender fit: ask about minimum deposit/LTV, property type, lease length, flats/factor restrictions, landlord experience, income and credit criteria, portfolio limits, repayment basis, early-repayment charges, valuation and rental-coverage method.
- Evidence: identity, income and tax documents where requested, bank statements, deposit trail, liabilities, property details/Home Report, projected rent evidence and a complete budget. Never omit commitments or assume an agreement in principle is an offer.
- Operational readiness: choose a managing approach, obtain suitable insurance advice, identify reliable contractors, understand safety obligations and plan for voids, arrears, repairs and a mortgage-rate change. A letting agent does not transfer every legal duty to the owner.
There is no universal deposit, rent multiple, yield, interest rate or acceptance threshold. Obtain current written criteria and a mortgage illustration before committing.
Acquisition, ongoing and contingency budget
Acquisition cash
Separate the purchase price and mortgage from acquisition cash. The acquisition budget should identify:
- deposit and any source restrictions;
- ordinary LBTT on the transaction, calculated under Revenue Scotland’s current rules;
- ADS separately, where the transaction and buyer meet the applicable conditions. ADS is an additional transaction tax, not a replacement for ordinary LBTT. This guide does not determine whether ADS applies, calculate an individual liability or give personal tax advice;
- solicitor/conveyancing, searches, registration and lender/valuation costs;
- broker, lender and product fees (quote-specific);
- initial furnishing, safety or compliance work, insurance and management setup; and
- a ring-fenced contingency, not money needed for completion.
Revenue Scotland’s page checked on 17 September 2026 states that the ADS rate is 8% for transactions on or after 5 December 2024, subject to a transitional rule tied to the contract and effective dates. Recheck the current rate, dates, conditions, exceptions and reliefs at transaction planning. Do not turn the worked percentage into a conclusion that ADS applies to a particular buyer.
Ongoing cash
Model mortgage payment or interest, insurance, factor/service charges, letting or management fees, repairs and maintenance, compliance checks, utilities where the owner pays them, accounting/admin, ground rent or other property-specific charges, expected voids and arrears. Ask the lender how its rental test treats each item: lender coverage is not the same as a personal profit calculation.
Contingency and downside
Keep accessible funds for a void, delayed repair, insurance excess, boiler or fabric failure, legal/possession costs where lawfully incurred, rate changes and an unexpected tax or compliance bill. A positive worksheet surplus does not establish affordability, tax treatment or a suitable reserve.
Ordinary LBTT and ADS: keep them separate
Ordinary LBTT is the land and buildings transaction tax that can apply to a chargeable Scottish purchase under the relevant bands and rules. ADS is a supplement that can apply in addition for certain additional-dwelling or other transactions. They are separate questions with separate conditions and time-sensitive guidance. This guide makes no personal tax conclusion, does not decide whether a buyer owns an “additional dwelling”, and does not advise on relief, repayment or company treatment. Use Revenue Scotland or qualified tax advice for the actual transaction.
Labelled hypothetical worksheet — arithmetic only
Not a forecast, quote, lender decision or supported market yield. Illustrative date: 17 September 2026. Replace every input with a dated written quote or current official rule before use.
| Input / calculation | Hypothetical input | Arithmetic / result | Caveat |
|---|---|---|---|
| Purchase price | £250,000 | £250,000 | Example only; no market claim |
| Deposit (input) | 25% | £62,500 | Lender minimum and source rules vary |
| Mortgage balance | price − deposit | £187,500 | Assumes valuation equals price; valuation may differ |
| Ordinary LBTT | £0 input pending calculation | Not totalled | Must calculate current bands; no personal tax conclusion |
| ADS rate for this dated illustration | 8% | £20,000 (250,000 × 0.08) | Official rate checked 17 Sep 2026 for qualifying transactions on/after 5 Dec 2024; transitional rule and personal applicability remain unresolved |
| Legal/search/registration placeholder | £1,500 | £1,500 | Obtain quote; not a typical-cost claim |
| Valuation placeholder | £500 | £500 | Lender/product-specific |
| Broker/lender/product fees | £0 input | £0 | Do not assume free; check illustration |
| Initial setup/furnishing placeholder | £3,000 | £3,000 | Property and letting model vary |
| Contingency reserve | £5,000 | £5,000 | Not a recommended reserve or guarantee |
| Cash before ordinary LBTT | sum above excluding ordinary LBTT | £92,500 | £62,500 + £20,000 + £1,500 + £500 + £3,000 + £5,000 |
| Gross monthly rent (input) | £1,500 | £18,000 annual | Hypothetical; not a rent estimate |
| Gross rent yield arithmetic | £18,000 ÷ £250,000 | 7.20% | Gross only; not a forecast or investment recommendation |
| Interest-only rate (illustrative input) | 5.00% | £9,375 annual interest | Not a quote; repayment basis and lender stress differ |
| Simple rent/interest coverage | £18,000 ÷ £9,375 | 1.92× | Not any lender’s rental test; excludes operating costs and tax |
| Example operating costs input | £4,800/year | £13,200 before tax/finance surplus | Hypothetical; does not prove profit or affordability |
The arithmetic is reproducible: £250,000 × 25% = £62,500; £250,000 − £62,500 = £187,500; £250,000 × 8% = £20,000; acquisition cash subtotal = £92,500; £1,500 × 12 = £18,000; £18,000 ÷ £250,000 = 7.20%; £187,500 × 5% = £9,375; £18,000 ÷ £9,375 = 1.92×. The 8% figure is dated official input, not a personal ADS conclusion. ADS and ordinary LBTT must not be double-counted or treated as interchangeable.
Private residential long lets are not short-term lets
For a private residential long let, check the Scottish landlord-registration requirement, the private residential tenancy framework and repair duties before marketing or granting a tenancy. The official Scottish Landlord Register, private residential tenancy policy and guidance, and mygov.scot repairs and maintenance guidance are the starting points. Confirm property-specific duties with the relevant council and qualified advice.
A short-term let is a separate planning and licensing question. Check the official when a short-term-let licence is needed and exclusions pages, plus the relevant council. Do not imply that landlord registration, a private residential tenancy, or a buy-to-let mortgage authorises short-term letting. Do not imply that short-term-let licensing replaces long-let tenancy or repair obligations. Unsupported EPC, council, planning or licence detail is intentionally omitted pending property-specific verification.
Local due diligence
Before offering, inspect the Home Report and title/tenure, factor or common-repair arrangements, insurance position, access and parking, permitted use, lease restrictions, local demand evidence and comparable achieved rents. Check flood, coastal, infrastructure, maintenance and licensing/planning questions with appropriate official or professional sources. A listing price or asking rent is not evidence of achievable rent. The council responsible for the property—not the mortgage broker—must answer local registration, planning and licensing questions.
