How Buy-to-Let Mortgages Differ from Residential Mortgages
Buy-to-let mortgages are assessed differently.
Lenders focus primarily on:
Rental income
Property value
Market demand
Investor experience
Your personal income matters, but rental viability is central.
Key Differences
Feature | Residential | Buy-to-Let |
Deposit | 5–10% | 20–25%+ |
Assessment | Income-based | Rent-based |
Rates | Lower | Higher |
Fees | Lower | Higher |
Kilmarnock mortgage brokers in Ayrshire help investors compare these differences effectively.
Deposit and Capital Requirements
Most buy-to-let lenders require:
Minimum 25% deposit
Additional cash reserves
Proof of maintenance funds
For a £160,000 flat in Kilmarnock, you may need:
£40,000 deposit
£5,000+ fees and reserves
Planning capital properly is essential.
Local advisers help structure deposits efficiently.
Rental Stress Testing: How Lenders Calculate Affordability
Lenders test whether rent covers mortgage payments.
This is known as the Interest Coverage Ratio (ICR).
Typical Requirements
125%–145% of mortgage interest
Calculated at higher “stress” rates
Example:
Mortgage interest: £500/monthRequired rent: £625–£725/month
If rent falls short, borrowing is reduced.
