Why landlords use limited companies

Holding buy-to-let in a limited company can be more tax-efficient for higher-rate taxpayers, since mortgage interest is a deductible business expense and profits are taxed differently to personal income. The best company BTL mortgage depends on your structure — most lenders want a special purpose vehicle (SPV) set up purely to hold property.

1. SPV buy-to-let mortgages

Most company BTL lending requires a special purpose vehicle with specific SIC codes for property. Best for landlords setting up a clean company structure to hold rentals — the widest lender choice. Always take tax advice before incorporating.

2. Trading company buy-to-let

A smaller group of lenders accept mortgages through an existing trading company rather than an SPV. Best for business owners wanting to buy property through their existing company — fewer lenders, so a broker is essential.

3. Director's personal guarantee lending

Company BTL almost always requires personal guarantees from the directors, so your personal finances still matter. Best to understand: the company borrows, but you remain personally accountable.

4. Portfolio limited company lending

For landlords building a portfolio in a company, some lenders specialise in multiple-property company structures. Best for scaling investors — these lenders understand portfolio cash flow and complexity.

Key things to weigh

  • Tax — company ownership suits some, not all; get specialist tax advice first
  • Rates — company BTL rates can be slightly higher than personal
  • Personal guarantees — directors remain liable
  • SPV setup — most lenders require the right company structure and SIC codes

Is it better to buy property through a limited company?

It can be more tax-efficient for higher-rate taxpayers, but not for everyone. Always take specialist tax advice before deciding.

What is an SPV?

A special purpose vehicle — a limited company set up purely to hold property, which most company BTL lenders require.

Are company buy-to-let rates higher?

Often slightly, but the tax efficiency can outweigh this for higher-rate taxpayers. Compare the overall position.

Do I need a personal guarantee?

Almost always — directors personally guarantee company BTL mortgages, so your personal finances still matter.
