What is the difference between an owner-occupier and an investment commercial mortgage?

An owner-occupier mortgage is for premises your own business trades from and is assessed on the business. An investment mortgage is for property you let to tenants and is assessed on the rental income.

Which one gets better terms?

It depends on the deal. Lenders sometimes view owner-occupiers as lower risk, but a strong investment with reliable tenants can be very attractive too. The terms follow the specific case.

How does the lender assess an owner-occupier mortgage?

By looking at the trading business — its accounts and profitability — and its ability to afford the repayments, alongside the property's value.

What if I occupy part and let part?

That mixed-use position often points to a semi-commercial mortgage, which weighs both the trading side and the let side.

Commercial mortgages on business and investment property are typically unregulated. Housn Capital is not FCA regulated and does not lend or advise — we introduce you to a specialist commercial finance broker.

Owner-occupier vs investment commercial mortgage

Q: How does the lender assess an investment mortgage?

By looking at the rental income, the strength and length of the tenancies, and whether the rent reliably covers the loan.

The two kinds of commercial mortgage turn on one question: do you trade from the property, or let it out? Here is what changes.

The question that decides it

There is one question at the heart of it: will you trade from the property, or let it to someone else? If your own business occupies the premises, it is an owner-occupier mortgage. If you let the property to tenants and live off the rent, it is an investment mortgage. Everything else about how the lender looks at the deal follows from that.

How each is assessed

Owner-occupier

The lender assesses your trading business — its accounts, profitability and ability to afford the repayments — alongside the property's value.

Investment

The lender focuses on the rental income, the strength and length of the tenancies, and whether the rent comfortably covers the loan.

In short, an owner-occupier lender is lending against your business; an investment lender is lending against a tenant's rent. Each has its own view of risk, and the terms and on offer reflect that.

Which applies to you

You run a business needing premises
Buying the building your company trades from points to an owner-occupier mortgage.
You are building a property portfolio
Buying to let a commercial unit to tenants points to an investment mortgage.
It is a bit of both
Occupying part and letting part — say a unit you trade from with a flat above let out — can point to a semi-commercial mortgage.
