Semi-Commercial Mortgages

Semi-commercial mortgages are designed for properties that are used in both residential and commercial terms – in other words, homes that are lived in by their owners but also used as their place of work.

This type of mixed-use mortgage agreement can be used to secure all kinds of properties that meet this description: semi-commercial mortgages can cover shops with flats above them, pubs or hotels with homes attached to them, or bed and breakfast hotels that are also used as residential properties. Other semi-commercial property examples include catteries and dog boarding kennels, as the pet accommodation will need to be separate from the main living area.

We understand that some applications are more complex than others. For example, if you’ve only been trading for a short time or if you have a confusing ownership structure, you may need to spend a little more time putting together an application that will convince your preferred lenders to take a view of your case. In addition, most lenders will usually want to see that at least 40% of the property is used for residential purposes, so you’ll need to ensure that you have the appropriate split in place.

Luckily, we have a specialist team of brokers on hand to introduce you to lenders who are more likely to accept your circumstances and offer competitive interest rates on semi-commercial mortgage deals.

Is a semi-commercial mortgage right for me?

If the property that you’re looking to mortgage has a combination of residential and commercial floorspace, then it’s likely this type of mixed-use mortgage will work for you. It’s worth bearing in mind that if your property has separate entrances for the commercial and residential parts of the building, these will be considered two separate entities, and you will need to take separate mortgages out against them: one for the commercial environment and one for the residential.

Mortgage lenders have very different understandings of semi-commercial and commercial properties, and there can be wide variances between them. As we mentioned earlier, some work on the 60/40 square footage rule, whereas some prefer to work on a monetary value perspective.

If you’re not sure what type of mortgage you need, we are more than happy to have a chat with you to understand what would work best in your specific circumstances.

What are the typical eligibility criteria for semi-commercial mortgages?

There are a few common eligibility criteria that lenders use to assess semi-commercial mortgage applicants, including:

  • Your deposit amount – how much you can afford to put down on the property to begin with
  • Your credit rating – and whether you have any severe black marks on your credit file that would ring alarm bells
  • The affordability of your mortgage – as in, whether or not you can afford your monthly repayments, based on your earnings and outgoings
  • Your trading history – how successful the commercial aspect of your property has been in terms of generating income
  • The overall strength of the investment

Let’s go into these in a little more detail.

Your deposit

As with any property purchase, you will need to organise a deposit. For semi-commercial properties, these are usually about the same as for a commercial purchase: between 20-40%. This figure can vary depending on the property and your own circumstances, as well as whether the property is owner-occupier or a commercial investment deal.

Owner-occupied commercial mortgages are for businesses that are buying premises with the purpose of working there, with a loan to value (LTV) of around 80%. Commercial investments have a slightly lower LTV of roughly 75%.

You can offset a semi-commercial mortgage with a higher LTV by putting down additional security measures, such as existing property or other assets you hold equity in.

Your credit rating

Your interest rate will usually be dependent on your own personal circumstances, so your credit report will have a bearing on your suitability for a mortgage. If you have a poor credit report, it may be more difficult to find a lender – but the key thing to remember is it’s not impossible. The team here at CLS Money works with a range of specialist brokers who have offered loans to people from all backgrounds and with all manner of past credit problems.

If you have a strong credit history, your options are likely to be increased, and you could access much better interest rates.


Any mortgage lender will want to have a good understanding of your current and projected income in order to assess the affordability of your semi-commercial mortgage. This will usually be worked out by looking at earnings before interest, depreciation, and amortisation (EBITDA).

Your lender will need to be reassured that your repayment schedule is both comfortable and doable. They may get the confirmation they need from the company’s own operating performance or from other legal income that you may have access to.

As always, it’s important that you look into a range of different mortgage providers to make sure you are getting the best deal.

Trading history

If this is a new venture for you and you are entering an industry that you have little to no experience in, this can work against you when seeking a semi-commercial mortgage. This is because some lenders want to see a proven history in the industry; it will give them more confidence that their investment will be safe.

This isn’t true all the time, and there are lenders who specialise in start-ups and first-time investors. However, you may need to provide a sturdy business plan and projections for expected revenue over the length of your mortgage term.

The strength and viability of the investment

Most lenders will only provide you with a mortgage if they are comfortable that the investment is sound, with many expecting around 190% forecast rental coverage for a business property, or 130% for a Buy to Let. It should be noted that these are averages and certainly not the expectations of all lenders.

What are the advantages of securing a semi-commercial mortgage?

Affordable interest rates

Mortgages on semi-commercial properties will usually have lower interest rates than other means of unsecured borrowing. Being able to secure fixed monthly repayments makes it easier to work these into your monthly forecasts and plan the finances of your business in a more concise way.

Capital gains

You can make quite a hefty amount of capital when you purchase a commercial property. This can be a great way of investing your money as, in most circumstances, property prices tend to rise over time, giving you a potential nest egg for the future.

Renting potential

If you own a commercial property, you can always choose to rent it out now or in the future if you wish, which will generate a continual income. You will need to take out a specific Buy to Let mortgage if you choose to go down this route, and you will need to bear in mind any existing leases that might already be in place.

No wasting money on rent

Your monthly repayment fees will be about the same, if not less than, what you would have been paying in rental fees. You will also benefit from the equity you have in your property growing over time, giving you more protection and security for the future.

Ending a mortgage is much easier

No matter the reason for ending your mortgage, there are more options available to you if you’ve taken out a semi-commercial option. For example, you can sell the property on to another investor or choose to rent it out to cover the mortgage payments instead.

We would always recommend that you speak to a specialist accountant to understand the tax benefits and implications for your specific circumstances.

What about the disadvantages of pursuing this kind of mortgage?

Your deposit

Deposits are usually higher for commercial properties than residential ones, and this is no different for semi-commercial properties. When you’re running a business, it can be a tricky decision to weigh up whether a big chunk of funds would be better invested in a property or spent on expanding your enterprises elsewhere.

Maintenance costs

As with any owned property, the general upkeep of the space will be down to you, so this can be an extra expense if any issues were to arise, such as a broken boiler. These additional (and often unexpected) costs will need to be factored into your overall affordability profile.

The potential drop in property prices

Any negative fluctuation in property prices could leave you in negative equity with your property. Although prices will usually rise again, if you find yourself in a rush to sell for any reason, this could reduce your capital and affect your future borrowing capacity.

Unsuitable or largely undesirable living space

Fewer people want to live in homes that are attached to busy and often noisy venues like pubs and hotels. If your semi-commercial investment includes a residential property, you’ll need to factor in its location and construction when marketing it to potential tenants; there may be a smaller pool of interested parties than you think.

Interest rates

If you choose a variable mortgage rate rather than fixed, there could be vast fluctuations in the amount you owe each month depending on how the interest rates change over time. The interest rates are based on the decisions of the Bank of England, so they are not something you will be able to negotiate with your lender if they start placing a squeeze on your finances.
