Buy-to-Let Guide: Returns, Tax & Getting Started
Is Buy-to-Let Still Worth It?
Buy-to-let can still be profitable but the margins are tighter than a decade ago due to tax changes, higher interest rates, and increased regulation. Success depends on location, purchase price, and your approach to management.
Understanding Rental Yield
Gross yield = annual rent / property value x 100. Net yield accounts for all costs (mortgage, maintenance, voids, management fees). Aim for 5-8% gross yield. Below 4% is generally considered too low to be worthwhile once costs are factored in.
Buy-to-Let Mortgage Requirements
Most BTL mortgages require a minimum 25% deposit. Lenders typically require the rental income to cover 125-145% of the mortgage payment. Interest rates are usually 1-2% higher than residential mortgages. You will need to pass affordability checks based on a stressed interest rate.
Tax Implications
Rental income is taxed as income at your marginal rate. Mortgage interest relief is limited to a 20% tax credit (no longer fully deductible). You pay 5% stamp duty surcharge on the purchase. Capital Gains Tax applies when you sell (18% or 24%). You must register with HMRC and submit a Self Assessment tax return.
Running Costs to Budget For
- Letting agent fees: 8-15% of rent
- Maintenance: Budget 10-15% of rent
- Insurance: Landlord insurance costs £200-400/year
- Void periods: Typically 4-8 weeks between tenants
- Safety certificates: Gas, electrical, EPC — £200-500/year
- Ground rent and service charges for leasehold properties
