Semi Commercial (Mixed-Use) Mortgages

Discover everything you need to know about semi-commercial and mixed-use property mortgages from the independent financing experts!

Financing Semi-Commercial Properties

A semi-commercial mortgage— also known as a mixed-use mortgage— is exactly as it sounds. These products are designed to finance the purchase or refinancing of a building split between residential and business use. For example, a flat above a shop or a pub with living space above would be considered a classic type of semi-commercial mortgage.

About Mixed-Use Property Mortgages

Semi-commercial mortgages are unique – they aren't the same as a mortgage you might take out against a residential property or building solely used for commercial trading. Their nature allows you to either buy or refinance properties for both uses.

Mixed-use mortgages also cover many property types, which are much more flexible than a standard commercial mortgage. If a home is attached to a premise that accommodates any business, from a shop to an office or storage unit, you might need a semi-commercial mortgage if both parts of the building fall under the same freehold agreement.

These apply to scenarios such as having a B&B or guest house where you live on-site as the owner. Because part of the property is a business rented to guests, and part is your home, you'll likely need a mixed-use mortgage to complete a purchase.

Mixed-Use Mortgage Rates

At Revolution Brokers, we pride ourselves on offering tailor-made semi-commercial mortgages catering to a wide array of client needs throughout the UK. A semi-commercial mortgage, or mixed-use mortgage, is ideal for properties that serve both residential and commercial purposes. This type of financing is an excellent choice for investors looking to diversify their portfolios with assets like shops with residential units above or mixed-use buildings combining offices and living spaces.

To qualify for a semi-commercial mortgage with us, you'll typically need a minimum 25% deposit of the property's value. However, this can vary depending on your circumstances and the lender's requirements. Our team of specialists is adept at navigating these complex lending criteria and can guide you through the process, ensuring that you secure the best possible terms.

We work with various lenders to provide up to 75% loan-to-value on these mortgages, accommodating first-time buyers and seasoned landlords. Our service is distinguished by our ability to handle complex cases, including those involving low personal income or less traditional income types, and we offer flexible terms to suit your unique investment strategy.

How Are These Mortgages Different From Other Mortgage Types?

From a mortgage lender's perspective, these mortgages are so different because any property purchase deal linked to a business premise needs to be approved by a provider who offers commercial lending. Residential mortgages are regulated and assessed very differently, so applicants for mixed-use mortgages are considered on a case-by-case basis since each scenario will relate to an alternative property.

It's also wise not to compare buy-to-let mortgages with these type of mortgages – even if you plan to rent out part of the semi-commercial property to help with the purchase costs, it remains a business venture, which carries a different profile than a property you're buying solely to rent out.

Semi-commercial mortgage lenders have multiple factors to consider before they make an offer to lend, from the viability of the business plan to the details of a lease agreement and the profitability you can reasonably expect to make.

Is A Semi-Commercial Mortgage Right for You?

While it might seem obvious that some properties will be eligible for commercial, residential, or buy-to-let mortgages, the reality is that this isn't always clear-cut. There are many situations where applicants are turned down for borrowing simply because they have applied to the wrong lender or for a financing option that isn't suitable.

Examples include situations where the property is split by significant percentages, such as 90% residential for a first-time buyer with a small workshop attached or a large building primarily used as a residential home but with one outbuilding used as a studio or production space. Assuming this property would be suited to a residential mortgage may need to be corrected.

The general rule is that you'll need a semi-commercial mortgage if there are any elements of a business within the property – irrespective of how much of the floor space or percentage it comprises.

Mixed-Use Property Mortgage Policies

To add to the confusion, some semi-commercial mortgage lenders also apply their own policies and lending terms, making it worthwhile speaking with our experts before you take any action to ensure you are fully informed. Variances between lenders can mean:

  • Some apply a policy called the 60/40 rule—if less than 60% of the property is used for commercial purposes, they'll consider it a residential mortgage and work to the standards regulated by the FCA.
  • Others work based on a financial split, requesting separate valuations of the different parts of the building. They might decide that the proportion of the premise worth the most dictates the type of mortgage lending they're prepared to extend.
  • Alternative lenders might take a different approach and offer two separate mortgage products, each covering a different proportion of the same building. However, this normally only works if you can divide the floorplans and have a separate entrance for each aspect of the property without any common areas.

As always, we recommend giving us a call or sending a message to determine which of the above applies or whether a lender you may be considering will use a different policy to evaluate the mortgage product that they feel is most appropriate.

What To Know Before Applying For Semi-Commercial Property Mortgage

Semi-commercial mortgages can be an excellent way to raise the financing required to purchase a home and simultaneously buy a business premise to trade from yourself or to let out to commercial clients or tenants.

Generally, semi-commercial properties perform well as investments and often better than buy-to-let residences, with average returns of roughly 8.7% compared to 5.8% on the median buy-to-let.

It's also worth thinking about the maintenance and running costs. Most business tenants are responsible for general repairs and business rates, meaning that a larger proportion of the rental income is profitable.

Renting to a residential tenant tends to mean higher expenses, as landlords are typically responsible for repairs, covering the costs of maintenance or replacing furnishings or appliances included in the rent.

However, it is also important to compare the mortgage costs and overall profitability alongside the slower capital appreciation normally associated with mixed-use properties, which tend to grow in value as a saleable asset at a slower rate than buy-to-lets.

Get A Property Valuations From A Trusted Commercial Mortgage Broker

Lenders may wish to arrange an independent valuation to assess the bricks-and-mortar value of the semi-commercial property.

However, suppose you have a mixed-use building where over half of the value is allocated to buy-to-let residential accommodation. In that case, the lender may waive this requirement if they can see evidence that the rental income will comfortably cover the mortgage costs.

Other lenders will decide to offer a buy-to-let mortgage for businesses for the entirety of the purchase or remortgage cost if they are happy the rental income is more than sufficient to offset their lending risk linked to the business element.

Although  depend on multiple factors, this could mean you gain a more competitive interest rate.

Lenders may also offer perks like free valuations and cashback. These incentives can be attractive, but it's imperative you consult an independent broker before you move ahead. That's because some 'free' services conceal the fact that product or application costs are far higher than other lenders, so you need to have complete oversight of the overall costs and total repayments associated with a semi-commercial mortgage to have full control of your finances.

Eligibility Criteria (Minimum Income,Deposit Value, etc.)

Lenders will typically need to see a deposit (or equity if you're refinancing) of between 20% and 40%, depending on factors like the amount of income you forecast generating from the property. If you have a lower risk profile, you'll generally be accepted with a deposit to the lower end of the scale, but applicants with greater risk will need as high a deposit as possible.

We cannot indicate any standard deposit because, as with all of these requirements, it depends on the lender. However, some niche semi-commercial mortgage providers take a flexible approach and may be better suited if you don't have 40% of the property value available as a cash down payment.

As a rough indication of the norms in UK mixed-use mortgage lending:

  • Owner-occupier mortgages, where you intend to run your own business from the property, typically need a minimum 20% deposit.
  • Investors buying a mixed-use property are often expected to have at least 25% as a down payment.

One factor here is that you can potentially borrow more as a total mortgage value if the borrowing comprises a lower proportion of the overall property valuation. For example, suppose you've owned a mixed-use property for some time and have built up equity. In that case, you may qualify for more competitive deals if your borrowing requirements amount to a smaller LTV of 50% or less than the property is worth on the open market.

Mixed-Use Mortgages, Affordability & Credit History

Like any mortgage application, a lender must assess whether they think you have the income and financial reserves to keep pace with your mortgage repayments. While commercial property mortgages aren't regulated like residential lending, the provider still needs adequate assurance that you are very unlikely to default and will consider a combination of residential and commercial elements and the loan-to-value proportions.

In essence, a repossession means a lender will need to sell the property below market value through a liquidation sale. If they have a large amount of debt secured against the property, and it sells for a low price, they may lose.

Therefore, the lender will require several pieces of information before evaluating whether you comply with their affordability policies. That might mean looking at your projected income, working on the basis of earnings before interest, tax, dividends, and amortization (known as EBITDA).

However, your EBITDA can't be used as a rock-solid metric to determine how much you can borrow since other lenders will use alternative assessment methods.

Your operating figures and how you intend to make your semi-commercial mortgage repayments will be needed. A few years of trading experience, along with budgets to quantify the accuracy of your forecasts, can help.

While new owners or landlords can apply for mixed-use mortgages, lenders will likely need additional information if you don't have an ongoing trading history. We can also review your finances and forecasts to provide more information on how much you can borrow.

FAQ
Frequently Asked Questions

Yes, shops and other business premises with a flat above are among the most common properties requiring a semi-commercial mortgage. As we've explained, the entrances will impact the most suitable mortgage.

Flats above shops that have independent entrances can be mortgaged separately as two standalone properties. However, you’d need a mixed-use mortgage to buy or refinance the property if the two parts of the building have shared entrances.

Lenders prefer applicants to have some experience either running the type of business concerned or renting commercial or residential properties – of course, depending on what they intend to use the property for.

Some mortgage providers will only accept applicants with a minimum level of experience, often ranging from six months to three years. Other lenders won't have any such requirements but will need to check carefully that you meet all the other eligibility criteria.

If you have a business plan or a full set of projections, this will assist with your semi-commercial mortgage application. There are numerous ways to utilise a mixed-use property, such as buying a business premise and letting out the residence, renting out both parts of the property, or letting the commercial unit while living in the other proportion.

Your selected lender will look at your figures to ensure the investment is sound and will generate a profit, so they'll ask for the following:

  • Projections and budgets
  • A copy of the business plan
  • Information about your business experience

Semi-commercial properties with an anticipated rental income of 190% of the monthly mortgage costs are often the minimum for this type of mortgage. However, if you’re buying a buy-to-let as a business asset, a lender might accept rental returns of around 130% of the mortgage repayments.

In any scenario, you'll need to show that the rent will reach 110% to 125% of the mortgage as a minimum threshold. However, other eligibility criteria apply, and the rental cover required by the lender might also depend on your tax bracket.

Working from home or running a business from your residence is becoming far more common, and we’re often asked whether that means a residential mortgage is no longer appropriate. Generally, you won’t need to remortgage onto a semi-commercial mortgage if you haven’t changed the property or made any modifications to make it suitable for business use.

Self-employed people often work from home and don't need to remortgage – instead, they can claim a proportion of the running costs as a tax-deductible expense.

However, this might change if you need to make modifications, such as building an outbuilding or creating a space specifically designed for a business that is not used for residential purposes.

The best way to verify your position is to contact your lender or get in touch with an independent broker who can provide further information. Most lenders will be happy to grant consent for you to work from home, which verifies your mortgage is suitable and won't need to be refinanced.

Potentially, yes. If you change the use of a building or alter a home into a business, you'll normally require planning permission. Change of use requires approval even if you don't make any changes to the appearance or layout of the property.

Mixed-use mortgage lenders may ask to see a copy of the planning permission if:

  • You intend to sell services or goods from the property.
  • Your premise will receive regular deliveries or visitors.
  • You want to advertise the business at your home address.
  • You’re running a business that requires a licence.

It’s also important to contact your insurer since you may need business insurance to safeguard any assets or inventory you store in your home – they won’t often be covered by household contents insurance.

Applicants running a business from home may not necessarily need a semi-commercial mortgage – we’ve explained this above in a little more detail. However, you may need to check with your lender to ensure you have the right type of mortgage for your property.

If you’ve not made any modifications, you're unlikely to need to remortgage since many people run small businesses from home or manage their admin or bookkeeping for a small business from their residential property.

However, we'd suggest taking out business insurance and checking with your local council whether they expect you to pay business rates. In most cases, business rates apply only to a proportion of the property used solely for commercial purposes. These costs may be tax deductible, including things like broadband, utilities and local council taxes, although this is best confirmed with an accountant.

An accountant can also advise if you are potentially liable for capital gains tax if you sell the property and a part of it is designated for business use – although this would be fairly unusual.

There are some scenarios when you will be obliged to remortgage to a semi-commercial product, either because your residential mortgage lender will not grant approval for you to run a business from the property or because the mortgage isn't a suitable option.

Other reasons to remortgage might be because it is financially advantageous. While commercial borrowing is generally more expensive than residential and carries higher interest rates, you may find that refinancing and repurposing part of the property for business use is considerably more cost-effective than buying or renting a separate building.

You might also find that building an extension or adding an outbuilding to run your business is the most viable solution, even if that means remortgaging. These solutions tend to be most suitable where you’re using 30% or more of your home for business use, in which case you may be eligible for a semi-commercial mortgage.

As always, we'd advise getting in touch for more information or to run through some like-for-like comparisons to see how varied options stack up.

Online mortgage calculators are handy tools if you'd like an indication of how much you're likely to be able to borrow, the minimum deposit required, and what the monthly costs may look like. However, we often reiterate that these calculators are generic and give you a rough idea – you shouldn’t make any financial decisions based on this information.

When you come to submit an application, you'll often find the rates offered, deposit requested, and other terms vary significantly from those displayed online since calculators can't factor in your credit rating, financial status and other elements relevant to the lender's eligibility assessment.

A far better option is to speak to a whole-of-market broker. We can ask a few background questions to get a more specific idea of what a lender might be prepared to offer – and which lenders are most likely to approve your application.

No – a semi-commercial mortgage is unlikely to be the best option unless you're operating a business from your home or using part of the property as a trading premise. Likewise, you can't apply for a business mortgage if you want to buy a property you intend to live in or have a living space within it.

Lenders will ask to review the property particulars and for some information about the business before they consider a semi-commercial mortgage application.

Changes in the way we work have meant a large number of people now run businesses from home. This trend is one reason semi-commercial mortgages have become in much higher demand and are available from a broader range of lenders.

Another factor is that landlords recognise the profitability of commercial buy-to-lets, particularly where changes to legislation affecting residential landlords and the expenses they can deduct from their income before paying taxes make this less appealing.

Mixed-use properties are treated as commercial investments for tax purposes, which means a landlord can reduce their tax liability by including the costs and mortgage interest in their accounts. They also do not need to budget for the 3% additional stamp duty levy payable against second homes, so there are several benefits.
