Buy-to-Let Explained

What Is Buy-to-Let?

Buy-to-let involves purchasing residential property specifically to rent it out to tenants.

Returns come from:

Monthly rent
Long-term price growth

Buy-to-Let Mortgage Rules (2025)

Key features:

Higher deposit required (usually 25%+)
Interest-only mortgages common
Affordability based on rental income

Buy-to-let mortgages differ significantly from residential mortgages.

Interest Rates & Stress Tests

Lenders apply stress tests to ensure:

Rental income covers mortgage payments
Buffer against rate rises

This affects affordability calculations.

Rental Yields Explained

What Is Rental Yield?

Rental yield measures the annual rental income as a percentage of the property’s value.

Gross Rental Yield Formula

Net Rental Yield

Accounts for:

Mortgage interest
Maintenance
Insurance
Management fees
Void periods

Net yield is far more important than gross yield.

Typical UK Rental Yields (2025)

London: Lower yields, higher capital growth
Northern England: Higher yields
Midlands: Balanced returns
University towns: Strong demand

Location is critical to success.

Costs of Property Investment

Ongoing Costs

Insurance
Compliance costs

One-Off Costs

Ignoring costs leads to poor returns.

Mortgage Interest Relief Restrictions

Landlords can no longer deduct mortgage interest from rental income in full.
Instead:

This disproportionately affects higher-rate taxpayers.

Buy-to-let properties

Stamp Duty significantly impacts upfront costs.

Inheritance Tax (40%)

Planning is essential for long-term investors.

Property Ownership Structures
