Commercial Investment Mortgage Guide
Financing Commercial Property to Let
Commercial property investment can provide an opportunity to own property that is occupied by another business and generates rental income.
This might involve purchasing a shop leased to a retailer, an office occupied by a professional business, an industrial unit rented to a trading company or another commercial property held primarily as an investment.
Financing these properties is different from arranging a residential buy-to-let mortgage.
With a commercial investment mortgage, the lender may need to assess not only the borrower and property, but also the tenant, lease, rental income, property value and overall quality of the investment.
This guide explains how commercial investment mortgages work and the factors lenders may consider.
What Is a Commercial Investment Mortgage?
A commercial investment mortgage is generally used to purchase or refinance commercial property that is occupied by a third-party business.
The borrower owns the property.
The tenant occupies the property and pays rent under a commercial lease.
The mortgage is secured against the commercial property.
Examples could include:
Shops
Offices
Warehouses
Industrial units
Workshops
Retail units
Business units
Professional premises
Other commercial investment property
Different property types and sectors can attract different lender criteria.
Commercial Investment vs Owner-Occupied Commercial Mortgage
The distinction is important.
An owner-occupied commercial mortgage is generally used when your own business will trade from the premises.
A commercial investment mortgage is generally used when you own the property but another business occupies it.
For an owner-occupied transaction, the lender may focus heavily on the trading business's ability to service the mortgage.
For a commercial investment, the lender may place greater emphasis on:
Rental income
Tenant
Commercial lease
Property
Investment value
Borrower's experience and financial position
The underwriting approach can therefore be very different.
How Does a Commercial Investment Mortgage Work?
Imagine an investor wants to purchase a commercial property for:
£500,000
The property is occupied by a business paying:
£35,000 per year in rent.
The investor provides part of the purchase price and applies for a commercial investment mortgage for the remainder.
The lender may then consider questions such as:
What is the property worth?
Is the rent sustainable?
Who is the tenant?
How long does the lease have left?
Does the rental income adequately support the proposed borrowing?
What happens if the tenant leaves?
This is why commercial investment lending is about considerably more than simply comparing the purchase price with the deposit.
What Types of Commercial Investment Property Can Be Mortgaged?
Potential property types include:
Retail units
Shops
Offices
Warehouses
Industrial units
Storage facilities
Workshops
Business units
Mixed commercial premises
More specialist properties may also be financeable, but lender appetite can become narrower.
The property itself is an important part of the lender's risk assessment.
How Much Deposit Do I Need?
There isn't one deposit requirement that applies to every commercial investment mortgage.
The amount of equity required can depend on:
Property type
Property value
Rental income
Tenant
Lease
Borrower
Experience
Loan size
Location
Lender appetite
Rather than assuming a particular deposit will be sufficient, the complete transaction should be assessed.
What Is Commercial Investment LTV?
LTV means loan-to-value.
It compares the mortgage with the value used by the lender.
For example:
Property value: £600,000
Mortgage: £390,000
The LTV would be:
£390,000 ÷ £600,000 × 100 = 65%
The remaining equity would need to come from the investor or an acceptable transaction structure.
However, the amount a lender is prepared to advance can also be restricted by rental-income requirements.
Why Isn't LTV the Only Limit?
Commercial investment lending can effectively have more than one constraint.
The property value might support a certain mortgage based on LTV, but the rental income may support less borrowing.
For example, the lender could be comfortable with the proposed LTV but decide that the rent doesn't provide sufficient coverage for the requested mortgage.
In that situation, rental affordability rather than property value may restrict the loan.
How Do Lenders Assess Rental Income?
Commercial lenders use their own methods to assess whether rental income adequately supports the proposed debt.
They may consider:
Current annual rent
Market rent
Mortgage interest
Required coverage
Lease
Tenant
Property
Vacancy risk
The precise calculation varies between lenders.
This is one reason a simple online mortgage calculator may not accurately determine commercial investment borrowing.
What Is Interest Cover?
Interest cover broadly compares the income generated by the investment with the interest cost of the borrowing.
A lender may want the rental income to exceed the mortgage interest by an appropriate margin rather than simply equal it.
The precise calculation and required margin vary between lenders.
What Is DSCR?
You may encounter the term Debt Service Coverage Ratio, or DSCR, in commercial lending.
Broadly, it is a measure of the income available to service debt compared with the required debt payments.
Different lenders and transaction types may calculate coverage differently.
The important principle is that lenders generally want evidence that the investment has sufficient financial capacity to support the proposed borrowing.
Why Does the Commercial Tenant Matter?
When purchasing a commercial investment, you're not simply buying a building.
You're often buying an income stream connected to a lease and tenant.
The lender may therefore want to understand:
Identity of the tenant
Tenant's business
Financial strength
Trading history
Rental-payment history
Lease obligations
Remaining lease term
A property occupied by an established tenant on a suitable lease can present a different proposition from the same property standing empty.
What Is Tenant Covenant Strength?
Covenant strength broadly refers to the perceived financial ability and reliability of a tenant to meet its obligations under the lease.
The lender may consider information about the tenant when assessing the security of the rental income.
This can be particularly important where the property's investment value is heavily dependent on the lease.
Does a Well-Known Tenant Guarantee a Mortgage?
No.
A recognisable tenant can be relevant, but the lender still needs to assess the entire transaction.
It may also consider:
Lease length
Break clauses
Rent
Property
Location
Valuation
Borrower
LTV
Overall lending proposition
No single factor guarantees approval.
Why Is the Commercial Lease So Important?
The lease governs the relationship between landlord and tenant.
For a commercial investment lender, it can therefore be a fundamental part of the security.
The lender and its solicitor may want to understand matters including:
Lease commencement date
Lease expiry date
Current rent
Rent-review provisions
Break clauses
Repairing obligations
Assignment provisions
Other material lease terms
The precise legal review is a matter for the solicitors.
What Is an Unexpired Lease Term?
This is the amount of time remaining before the tenant's current lease expires.
For example, if a ten-year lease was granted four years ago, approximately six years may remain, subject to the actual lease terms.
The remaining term can affect how the lender and valuer view the investment.
Why Do Break Clauses Matter?
A break clause can potentially allow a tenant or landlord to terminate a lease before its contractual expiry date, subject to its terms.
Suppose a property appears to have eight years remaining on the lease but the tenant has an exercisable break option considerably earlier.
The lender may consider that when assessing the security of future rental income.
The actual lease should therefore be reviewed rather than relying solely on the headline expiry date.
What Is a Rent Review?
Commercial leases can contain provisions allowing rent to be reviewed during the lease term.
The review mechanism depends on the lease.
A lender and valuer may consider the current rent, market rent and lease provisions when assessing the investment.
Don't assume future rental increases are guaranteed.
What Is Market Rent?
Market rent is broadly the rent that a property could reasonably be expected to achieve in the market under appropriate letting conditions.
The current contractual rent and market rent aren't necessarily identical.
A tenant could be paying:
Above-market rent
Market rent
Below-market rent
This can affect valuation and underwriting.
What If the Tenant Is Paying Above-Market Rent?
A high contractual rent can look attractive.
However, a commercial valuer may consider whether that rent is sustainable and what rent could reasonably be achieved if the existing tenant left.
The lender may therefore not simply capitalise an unusually high rent without considering the wider market.
What If the Property Is Vacant?
Vacant commercial investment property can still potentially be financeable, but the proposition changes.
Without a tenant, there may be no current rental income supporting the mortgage.
The lender may want to understand:
Proposed tenant
Expected rent
Letting strategy
Investor's experience
How mortgage payments will be covered during vacancy
Demand for the property
Exit strategy
Alternative or short-term finance may sometimes be considered depending on the circumstances.
What Is Vacancy Risk?
Vacancy risk is the possibility that the property stops producing rent because there is no tenant.
Commercial investors should consider what would happen if:
Tenant leaves
Tenant fails
Lease expires
Property requires refurbishment
Finding another tenant takes several months
Mortgage payments and other property costs can continue even when rental income stops.
What Happens If the Tenant's Business Fails?
The consequences depend on the circumstances and lease.
From a mortgage perspective, the key issue is that the property's rental income could be interrupted.
Investors should therefore avoid treating the current rent as guaranteed income for the entire mortgage term.
What Is Commercial Property Yield?
Yield is one method of considering the income generated by a commercial investment relative to its value or purchase price.
A simplified gross-yield calculation is:
Annual rent ÷ Purchase price × 100
For example:
Purchase price: £500,000
Annual rent: £35,000
Gross yield:
£35,000 ÷ £500,000 × 100 = 7%
This is only a simplified gross calculation.
It doesn't account for all the costs associated with owning the property.
Gross Yield Isn't the Same as Profit
An investor may need to pay for:
Mortgage interest
Repairs
Insurance
Professional fees
Management
Void periods
Legal costs
Service costs
Taxation where applicable
Capital expenditure
A headline yield should therefore not be confused with the investor's actual return.
Does a Higher Yield Mean a Better Investment?
Not automatically.
Yield is only one measure.
A higher yield can sometimes reflect additional perceived risk.
For example, investors may consider:
Property condition
Tenant
Lease
Location
Vacancy risk
Future demand
Capital expenditure
Mortgage advice shouldn't be treated as investment advice about whether a particular commercial property represents a good investment.
How Is a Commercial Investment Property Valued?
Commercial investment valuation can differ significantly from a conventional residential valuation.
The valuer may consider:
Property type
Location
Current rent
Market rent
Tenant
Lease
Remaining lease term
Break clauses
Comparable transactions
Investment yield
Marketability
Condition
The valuation methodology depends on the property and transaction.
What Does Capitalising the Rent Mean?
In simplified terms, commercial investment valuation can involve considering the property's income and applying an appropriate market yield to determine an investment value.
This is more sophisticated than simply multiplying the annual rent by a fixed number.
The appropriate yield can depend on the:
Property
Location
Tenant
Lease
Market
Risk
The lender relies on its professional valuer rather than a simple online yield calculation.
What Is Vacant Possession Value?
The lender may also be interested in what the property could be worth without the benefit of the existing tenancy.
This is commonly referred to as vacant possession value.
It can help the lender understand its security if the existing rental arrangement no longer exists.
What If the Property Is Down-Valued?
Suppose you agree to purchase a commercial investment for:
£600,000
but the lender's valuation supports:
£550,000
The lender may calculate its maximum mortgage against the lower figure.
That could require:
Additional investor equity
Renegotiation of the purchase price
Reduction in borrowing
Review of the transaction
Another lender isn't guaranteed to produce a different valuation.
Can I Buy Commercial Property Through a Limited Company?
Potentially.
Commercial investment property can be held through different ownership structures.
A limited company may be considered, but the appropriate structure depends on:
Investor
Property
Existing portfolio
Tax position
Long-term strategy
Lender requirements
Mortgage advice shouldn't replace tax or legal advice.
Discuss ownership structure with appropriate professionals before exchanging contracts.
Does It Have to Be an SPV?
Not necessarily.
SPVs are widely discussed in residential buy-to-let, but commercial investment lending can involve a variety of corporate structures.
Lenders may consider:
Existing companies
Newly incorporated companies
Property investment companies
Other acceptable structures
Criteria vary considerably.
Don't incorporate a company solely because you assume every commercial lender requires an SPV.
Can I Buy Commercial Property Personally?
Potentially.
Individuals can also own commercial investment property.
The appropriate ownership structure should be considered alongside tax and legal advice.
Changing ownership later can have financial, legal and tax consequences, so consider the structure before purchase rather than afterwards.
Will Directors Need to Give Personal Guarantees?
Potentially.
Where a limited company is borrowing, a commercial lender may request personal guarantees from directors, shareholders or other relevant individuals.
A personal guarantee can create personal liability if the borrowing company doesn't meet obligations covered by the guarantee.
Understand the legal consequences and obtain appropriate independent legal advice where required.
Can I Buy a Commercial Investment With a New Limited Company?
Potentially.
A newly established property company may not have its own trading history.
The lender may therefore consider other factors, including:
Directors
Shareholders
Experience
Personal financial position
Property
Tenant
Lease
Deposit
Overall transaction
The lack of historic company accounts doesn't necessarily mean every lender will decline the case.
Does Commercial Property Investment Experience Matter?
It can.
An experienced commercial property investor presents a different profile from somebody buying their first commercial investment.
The lender may consider:
Existing portfolio
Property-management experience
Previous commercial investments
Borrowing history
Financial position
First-time commercial investors may still have options, subject to lender criteria.
Can a First-Time Landlord Buy Commercial Property?
Potentially.
Not every lender requires previous landlord experience.
However, some transactions can be more suitable for experienced investors than others.
A straightforward tenanted commercial unit can present a different proposition from a complex multi-unit or specialist investment.
Can I Use a Commercial Mortgage for a Shop With a Flat Above?
Potentially, but this is usually a different category.
A property containing both commercial and residential accommodation is often described as:
Semi-commercial
Mixed-use
Mixed commercial and residential
Different lender criteria can apply.
Our Semi-Commercial Mortgage Guide covers this separately.
Can I Finance Multiple Commercial Units?
Potentially.
An investor might own:
Several individual commercial properties
A multi-unit industrial estate
A parade of shops
A mixed commercial portfolio
The lender may assess the portfolio as well as the individual property.
The structure becomes increasingly important as the portfolio becomes more complex.
Can I Refinance a Commercial Investment?
Yes, subject to lender criteria.
Reasons could include:
Existing mortgage approaching maturity
Reviewing borrowing costs
Raising capital
Restructuring debt
Releasing equity
Funding another purchase
Replacing short-term finance
The lender will need to understand the purpose of additional borrowing.
Can I Release Equity to Buy Another Property?
Potentially.
Suppose a commercial investment has increased in value or the mortgage balance has reduced.
There may be equity available.
A lender could potentially consider refinancing and releasing part of that equity, subject to:
LTV
Rental coverage
Property
Borrower
Purpose
Lender criteria
Equity isn't automatically available simply because the property value exceeds the mortgage.
What If the Existing Commercial Mortgage Is Expiring?
Commercial mortgages don't necessarily operate in exactly the same way as residential mortgage products.
If your existing facility is approaching maturity, start reviewing it early.
The refinance may require:
New underwriting
Updated valuation
Financial information
Lease information
Legal work
Waiting until shortly before the existing facility expires can unnecessarily restrict your options.
Can I Use Bridging Finance to Buy Commercial Investment Property?
Potentially.
Bridging finance may be considered where the transaction requires short-term funding, for example because:
Completion is required quickly
Property is vacant
Works are required
Long-term finance isn't immediately available
However, bridging finance is short-term borrowing and normally requires a credible exit strategy.
Its costs and risks should be properly understood.
What Is the Exit Strategy?
Where short-term finance is involved, the exit strategy explains how it will be repaid.
For example:
Purchase with bridging finance → secure suitable tenant → refinance onto commercial investment mortgage
might be a proposed strategy.
But the refinance shouldn't simply be assumed.
The likely long-term mortgage needs to be considered before entering the short-term borrowing.
What Fees Are Involved?
Potential commercial investment costs can include:
Deposit
Lender arrangement fee
Commercial valuation
Legal fees
Lender's legal costs where applicable
Searches
Adviser/broker fee
Survey
Property taxation
Insurance
Other lender or transaction-specific charges
The total cost matters, not simply the interest rate.
Will the Lender Require Its Own Solicitor?
Potentially.
Commercial mortgage transactions can involve more extensive legal work than standard residential mortgages.
The lender may have its own representation or specific legal requirements.
The borrower can potentially be responsible for some or all associated lender legal costs depending on the terms.
Establish this early when budgeting.
What About VAT on Commercial Property?
VAT treatment can be relevant to some commercial property transactions and leases.
This can materially affect the cash required for a purchase.
It is a specialist tax matter and shouldn't be assumed from the mortgage structure.
Your solicitor and appropriately qualified tax adviser/accountant should establish the position for the specific property and transaction.
What About Stamp Duty Land Tax?
Commercial property purchases in England can be subject to Stamp Duty Land Tax.
The treatment depends on the transaction and current rules.
Tax rules can change, so obtain an up-to-date calculation from your solicitor or appropriate tax professional before committing to a purchase.
What Insurance Might I Need?
Commercial property owners may need appropriate insurance for the building and associated risks.
The requirements depend on:
Property
Lease
Lender
Occupation
Business activity
The mortgage lender may impose specific insurance requirements as a condition of lending.
What Happens If Interest Rates Rise?
If the borrowing has a variable interest rate, an increase in the applicable rate can increase the cost of servicing the mortgage.
Even where the initial borrowing is fixed, investors should consider what could happen when that arrangement ends.
Commercial investment should therefore be assessed with some resilience rather than assuming today's borrowing cost remains unchanged indefinitely.
Should I Choose Fixed or Variable Commercial Borrowing?
That depends on the products available and your circumstances.
Considerations can include:
Certainty of payments
Expected ownership period
Early repayment provisions
Flexibility
Refinancing plans
Overall cost
The structure should be considered alongside the investment strategy rather than based on a prediction of future interest rates.
What Are Early Repayment Charges?
Some commercial mortgages can impose charges if the borrowing is repaid before an agreed point.
This can matter if you expect to:
Sell
Refinance
Reduce the mortgage substantially
Restructure the investment
Understand the early repayment provisions before accepting the loan.
What Happens When the Commercial Lease Expires?
That depends on the lease, tenant and legal circumstances.
From an investment perspective, consider the possibility that the existing tenant may not remain indefinitely.
A future letting could involve:
Different rent
Void period
Refurbishment
Legal fees
Agent fees
Incentives to a new tenant
Commercial investment should therefore not be assessed on the assumption that today's rental income will continue unchanged forever.
What Is a Void Period?
A void is a period when the property doesn't have a rent-paying tenant.
During a void period, the owner may still have expenses.
Potential costs can include:
Mortgage
Insurance
Security
Maintenance
Utilities
Certain property-related charges
Maintaining adequate financial reserves can therefore be important.
What If the Tenant Wants to Leave Early?
The legal position depends on the lease.
This is why break clauses and other lease provisions should be properly understood before purchasing the investment.
Your solicitor should explain the lease and your rights and obligations as landlord.
Should I Read the Lease Before Making an Offer?
For a tenanted commercial investment, the lease is fundamental to what you're buying.
Obtain appropriate professional advice rather than relying solely on an estate agent's marketing summary.
The actual lease may contain information that materially affects the investment.
Questions to Ask Before Buying a Commercial Investment
Consider:
Who is the tenant?
How strong is the tenant financially?
How much rent is being paid?
Is that rent consistent with the market?
How long remains on the lease?
Are there break clauses?
What happens when the lease expires?
How easily could the property be re-let?
What would the property be worth vacant?
What repairs might be required?
Can I afford the mortgage during a void?
How much cash will remain after the purchase?
What are the tax implications?
What is my long-term exit strategy?
The mortgage should be considered alongside the commercial characteristics of the investment.
Commercial Investment Mortgage Process
A typical transaction may involve:
1. Establish the Investment
Property, purchase price, rent, tenant and lease are reviewed.
2. Establish the Borrowing Requirement
Deposit, mortgage amount and ownership structure are considered.
3. Review Potential Lenders
Commercial lender appetite is assessed against the property and transaction.
4. Indicative Terms
Where appropriate, indicative commercial lending terms may be obtained.
These aren't necessarily a mortgage offer.
5. Full Application
The lender receives the required information and documentation.
6. Underwriting
The borrower, property, tenant, lease and financial proposition are assessed.
7. Commercial Valuation
An appropriate commercial valuation is completed.
8. Legal Due Diligence
Solicitors review the title, lease, security and other relevant legal matters.
9. Formal Offer
The lender may issue formal terms once its requirements have been satisfied.
10. Completion
The mortgage completes once the lender's conditions and legal requirements are met.
The exact process varies between lenders.

Commercial property involves considerations such as:
Commercial leases
Tenant covenant
Commercial valuation
Business occupation
Different legal arrangements
Specialist lender appetite
A residential buy-to-let approach shouldn't automatically be applied to a commercial investment.

Important Information
This guide provides general information and shouldn't be treated as personalised commercial mortgage, investment, legal, accounting or tax advice.
Commercial property values and rental income can fall as well as rise. Tenants can leave or fail to meet their obligations, and periods without rental income may occur.
Commercial mortgage criteria, interest rates, loan-to-value requirements, rental-coverage requirements, fees and security requirements vary between lenders.
Some forms of commercial mortgage and business lending aren't regulated by the Financial Conduct Authority. The regulatory position depends on the circumstances of the transaction.
Where personal guarantees, debentures or other security are required, appropriate legal advice should be obtained.
