Buy-to-Let Mortgages for Limited Companies Explained (2026)

As tax rules and lending criteria evolve, understanding how limited company buy-to-let mortgages work is becoming essential for landlords looking to scale their investments.

What Is a Limited Company Buy-to-Let Mortgage?

A limited company buy-to-let mortgage is a mortgage taken out by a company rather than an individual.

Most landlords use an SPV company structure specifically created for property investment purposes.

The company owns the property, collects rental income, and pays corporation tax on profits.

Why Are Landlords Using Limited Companies?

One of the main reasons landlords use limited company structures is mortgage interest tax treatment.

Within a limited company:

Mortgage interest is usually treated as a business expense Profits are subject to corporation tax Retained profits can be reinvested into additional properties

This can be attractive for higher-rate taxpayers and portfolio landlords.
