To buy a rental property, you’ll typically need:
- 25% deposit of the purchase price
- 75% mortgage from a buy-to-let lender
So for a £200,000 property:
- Deposit = £50,000
- Mortgage = £150,000
You can raise the deposit from:
- Savings
- Remortgaging your own home to release equity
- Inheritance or gifts from family
- Joint venture partnerships
🧾 Can I Afford It?
- Residential mortgages are based on your personal income
- Buy-to-let mortgages are based mainly on the rental income the property is expected to generate
- Lenders usually require the rent to cover at least 125–145% of the mortgage payments, at a “stress-tested” rate (often 5.5–6%).
Rental Stress Test Requirements:
Lenders typically require your rental income to cover 125% to 145% of the monthly mortgage payment, using a stress-tested interest rate (in this case, 5.5%).
Minimum required rental income (125%):
£687.50 × 1.25 = £859.38/monthStricter requirement (145%):
£687.50 × 1.45 = £997.88/month
To pass the Buy-to-Let mortgage affordability test, your property’s monthly rental income should be at least between £859.38 and £997.88.
If the actual rent falls below this range, the lender may reduce the loan amount, require a higher deposit, or reject the application.
🔒 Fixed or Variable Rate Mortgage?
You’ll choose between:
- Fixed Rate – The interest rate stays the same for 2, 5, or 10 years
- Variable Rate – Follows the Bank of England base rate (currently 4.5%)
🔑 Tip: Most investors prefer a fixed-rate mortgage for predictable monthly payments and easier budgeting.
📌 How long do you need to repay a buy-to-let mortgage? How much is the monthly payment?
- Property purchase price: £200,000
- 25% deposit: £50,000
- Loan amount (mortgage): £200,000 – £50,000 = £150,000
- Interest rate: 5.5% (fixed for the first 5 years)
- Loan term: 25 years (interest-only for the first 5 years)
- Repayment method: Interest-Only Mortgage — Monthly payment of £687.50 (only interest during the first 5 years)
This amount only covers the interest and does not include any repayment of the principal.
🏦 Why Interest-Only Mortgage Works for Investors
Buy-to-let investors often use interest-only mortgages, where:
- You only pay interest monthly (not the loan itself)
- Monthly payments are much lower
- After years of property growth, you can refinance or sell to repay the loan
💡 Example:
Buy at £200,000 → In 20 years, it may be worth £400,000
You sell or refinance and keep the profit!
📉 What Upfront Costs Should I Expect?

📈 How Do I Know If It’s a Good Investment?
Simple calculation:
Monthly Rent – Monthly Costs = Monthly Cashflow (Profit)
💡 If your rent is £1,000 and expenses total £800, your cashflow is £200/month profit.
You want positive cashflow, so the rent covers your costs and leaves you income.
🏠 What Type of Property Should I Start With?
Best for beginners:
- A single-let house or flat, rented to a family, couple, or individual
Advantages:
- Easy to manage
- Steady monthly rent
- Good resale potential
- Lower risk
Other strategies (for later):
- HMO (House in Multiple Occupation) – More tenants, more income, more rules
- Serviced Accommodation – Short-term lets like Airbnb (higher income, higher work)
📍 Where Should I Invest?
Stick to areas where you:
- Live or work and know the local market
- Understand where demand is high
- Can identify good vs. bad streets
Ask yourself:
- Is there strong rental demand?
- Will your ideal tenant want to live in this area?
Good transport, schools, shops, and job opportunities = higher rental demand.
