Commercial mortgages in Cambridge: a guide for business owners and investors

A commercial mortgage is a loan secured against a property used for business purposes. Whether you’re buying an office, retail unit, workshop, warehouse, or a mixed-use building in and around Cambridge, the lending process is different from residential mortgages.

This guide explains how commercial mortgages work, what lenders typically look at, and what to consider when financing commercial property in Cambridge—whether you’re buying to occupy the premises or to let to a tenant.

How commercial mortgages differ from residential

Commercial mortgages follow the same core principle as residential lending—borrowing against property security—but the terms, assessment and risk factors are usually more complex.

Deposit and loan-to-value (LTV)

Commercial lenders commonly require a deposit in the region of 25–40%, depending on the property type, the strength of the rental income (if relevant), and the borrower profile. This often results in maximum LTVs around 60–75%.

Interest rates

Commercial mortgage pricing is typically higher than residential. Rates can vary based on the lender, the LTV, the property category, and how robust the borrower’s ability to service the debt is.

Term length and repayment structure

Commercial mortgage terms are often shorter than residential. 15–25 years is common, and some facilities are structured with a balloon payment due at the end of the term.

Assessment approach

Instead of focusing mainly on personal affordability, lenders look at a combination of:

• the property’s value and condition
• the borrower’s financial position and track record
• the business’s ability to generate income (for owner-occupied cases)
• the rental income and lease strength (for investment cases)

Regulation

Most commercial mortgages are not regulated in the same way as residential mortgages. That means the protections and processes you may expect from a regulated residential mortgage can differ.

What lenders look at

Commercial lending is built around risk management. Lenders want confidence that the loan can be serviced and that the property provides reliable security.

1) The business (owner-occupied lending)

If you’re buying commercial property to run your business from, lenders typically assess:

• trading performance and profitability
• cash flow and ability to meet repayments alongside existing commitments
• business stability and experience

Many lenders prefer at least two years of filed accounts, though some may consider newer businesses where the financial position and plan are clear.

2) The property

The property is central to the decision. Lenders consider:

• property type (office, retail, industrial, mixed-use)
• condition and any required works
• location and marketability
• current rental value and potential rental value (where applicable)
• how easily the property could be sold or re-let if circumstances change

In general, straightforward, standard commercial premises in established locations are easier to finance than highly specialist or unusual assets.

3) The borrower

Lenders assess the borrower’s overall financial position, credit history, and experience.

For limited company borrowers, lenders may also require personal guarantees from directors depending on the structure of the deal and the risk profile.

4) Rental income and lease strength (investment lending)

For commercial investment properties, lenders often focus on whether the rent can support the mortgage payments with an appropriate margin.

Key factors include:

• the tenant’s covenant strength
• the length of the lease remaining
• lease terms and any rent review provisions
• void risk and how quickly the property could be re-let

Owner-occupied vs investment commercial mortgages

Understanding which category your purchase falls into helps shape the lender’s assessment.

Owner-occupied commercial mortgages

You buy the property to use for your business. In these cases, lenders place greater weight on:

• the business’s trading performance
• affordability and cash flow
• the relationship between business income and mortgage repayments

Commercial investment mortgages

You buy the property to let to a third-party tenant. Here, lenders place greater weight on:

• rental income
• tenant quality and lease terms
• the property’s ability to retain value and generate income

Mixed scenarios

Some borrowers occupy part of the property and let the remainder. This is common in mixed-use buildings and can affect how the lender treats the application—particularly where the split between commercial and residential elements is significant.

Semi-commercial and mixed-use properties in Cambridge

Cambridge has many buildings with both commercial and residential components—for example, retail or office space at ground level with residential accommodation above.

Lending on mixed-use properties often sits between residential and commercial criteria. Lenders may treat the property as commercial, residential with additional conditions, or use a dedicated mixed-use approach.

A key practical factor is the split between commercial and residential floor space. That split can influence which lenders are most suitable and how the deal is structured.

Commercial property and mortgages in Cambridge

Cambridge’s commercial market is influenced by the city’s wider economic ecosystem, including the technology and life sciences sectors and the university and innovation environment.

This can support demand across different property types, including:

• offices and business space near major innovation hubs
• industrial and logistics-style premises serving local businesses
• retail and hospitality premises in established city centre locations
• mixed-use buildings where ground-floor commercial space supports residential accommodation above

For borrowers, the local market context matters because lenders consider how marketable the property is and how confidently it could be let or sold if needed.

What does a commercial mortgage cost?

The total cost of a commercial mortgage is more than the interest rate. Typical components include:

• Interest rate: varies by lender, LTV, property type and borrower strength.
• Arrangement or facility fees: often charged as a percentage of the loan amount.
• Valuation fee: commercial valuations are usually more detailed than residential valuations.
• Legal fees: commercial conveyancing can be more complex, involving both borrower and lender legal work.
• Broker fee (if applicable): any broker charges should be clear before proceeding.

When comparing options, it’s important to look at the overall cost of the facility on a like-for-like basis, not just the headline rate.

Frequently asked questions

How much deposit do I need for a commercial mortgage in Cambridge?

Deposits of around 25–40% are commonly seen, which can translate into maximum LTVs of roughly 60–75%. The exact deposit depends on the property type, the lender, and—where relevant—the strength of the business or rental income.

Is it easy to get a mortgage on a commercial property?

It depends on the property, the borrower, and the structure of the deal. Financing is often easier where the property is standard and marketable, the business has a clear trading record (for owner-occupied cases), or the tenant and lease are strong (for investment cases).

What determines the term and repayment structure?

Commercial lenders commonly prefer shorter terms than residential lending, and some facilities include a balloon payment at the end. The term you can access may depend on the property type, the borrower profile, and how the lender views exit risk.

Can I get a commercial mortgage through a limited company?

Yes. Many commercial mortgages are taken through limited companies, including structures such as special purpose vehicles (SPVs). Lenders may assess the company’s financials and may require personal guarantees from directors depending on the circumstances.

What is a semi-commercial mortgage?

A semi-commercial or mixed-use mortgage is for a property with both commercial and residential elements. Lending criteria can vary depending on the split between commercial and residential floor space and the lender’s approach.

Key points to consider before applying

• Confirm whether the purchase is owner-occupied, investment, or mixed-use, as this changes lender assessment.
• Expect higher deposits and potentially shorter terms than residential lending.
• Be prepared for a more detailed review of the business, property, and (where relevant) the tenant and lease.
• Consider the impact of mixed-use floor space on how the property is categorised.

If you’re planning a commercial purchase in Cambridge, understanding how lenders evaluate risk can help you approach the process with realistic expectations about structure, costs and documentation.
