Can I get a mortgage on a flat above a shop or commercial premises?

Why lenders treat these flats differently

The security for the loan is the flat, but the valuer is instructed to consider what sits underneath it. Lenders worry about three things: resale demand, because some owner occupiers and their lenders avoid flats above certain businesses, which thins the market the lender would sell into after repossession; nuisance, meaning noise, smells, vermin risk and late opening hours; and structural or fire risk, including commercial extraction ducting running past habitable rooms. None of this stops the flat letting well, and rental demand for these flats is often strong because they sit in parades and high streets, which is exactly the mismatch that creates a specialist lending market.

The hierarchy of what is underneath

Lender appetite follows the commercial use, roughly in this order. Offices, hairdressers, opticians and similar quiet daytime uses are the easiest, and several mainstream buy to let lenders will consider them. General retail, cafes and convenience stores sit in the middle. Hot food takeaways, restaurants, pubs, launderettes and anything with late hours or heavy extraction are the hardest, and these usually need specialist lenders. A small number of uses, for example premises with flammable storage, can rule out lending altogether. The valuer's comments on the specific unit usually decide the case, not the category alone.

What the underwriter asks beyond the usual tests

Expect questions on: whether there is separate street access to the flat, since access through the shop is a common decline; who owns the freehold and whether the flat's lease is separate from the commercial unit; the percentage of commercial use in the block, since a flat that is 30% of a building that is 70% commercial is a harder sell than one above a single small shop; the lease length and service charge terms; and the tenancy type intended for the flat. A flat on its own long lease, with its own entrance, above a quiet daytime business, is close to a standard case.

A worked example of the pricing difference

Take a flat above a hot food takeaway valued at £120,000, bought through a limited company at 75% loan to value, so a £90,000 interest only loan with a £30,000 deposit. For illustration, suppose a mainstream lender would price a standard flat at 4.5% and the specialist lender prices this one at 5.5%.

The premium is £75 a month, or £900 a year. The stress test also bites harder at the higher rate: at a typical limited company interest coverage ratio of 125% and a 5.5% stress rate, the £90,000 loan needs rent of £90,000 x 0.055 x 1.25 / 12, about £516 a month. Flats in this bracket often rent well above that, which is why the deals still work, and these flats also tend to sell at a discount to comparable standard flats, so the yield is often higher.

What slows these cases down

Valuation is the usual bottleneck. Valuers frequently apply a saleability discount or note the commercial use in terms that make the first choice lender withdraw, and the case then needs re-placing with a lender whose criteria match the specific use underneath. Leases split badly between the flat and the shop, missing fire safety information and freeholders who run the business downstairs all add weeks. Cases placed correctly at the outset, with the commercial use disclosed and the right lender chosen first, complete in a normal buy to let timescale. This placement judgement is a large part of what a commercial finance broker does on non-standard property.

Where these flats sit in a wider portfolio

Investors drawn to these flats for yield are often weighing them against other higher yield options, most commonly houses in multiple occupation. The trade offs are different: the flat above a shop carries a valuation and resale question, while an HMO carries licensing and management load, and the lender panels for each barely overlap. Our guide to how HMO mortgages differ from standard buy to let sets out that comparison. Lenders typically look at the whole picture, so one non-standard property rarely affects the rest of a portfolio application.
