How much deposit do I need for a commercial mortgage

Planning a commercial property purchase in Mayfair? Secure a prime commercial property by budgeting 25% – 40% for a deposit. Lenders typically require higher amounts (25% -35% minimum) for high-value locations due to the higher risks involved. A 30%+ commercial mortgage deposit improves your approval odds and helps secure better rates. Deposits vary depending on your credit ratings, the type of business you run, the amount you wish to borrow and the property type. Owner-occupied properties may find better terms than investment mortgages.

What is a Commercial Property Mortgage?

A commercial property mortgage is a secured loan used by businesses to purchase, refinance or develop commercial real estate, such as retail spaces, offices or industrial units. The property itself is used as collateral. These mortgages offer loan terms of 3 to 25 years, with a 60%- 75% LTV. Commercial mortgage deposits can range from 25% to 40% of the property’s value.

Commercial mortgage is different from residential loans in terms of the higher value of the land or property. The rate you pay depends on your individual circumstances.

• Interest Rates Structures

Fixed or variable commercial mortgage interest rates are available for London properties. Fixed rates offer stability or budgeting businesses, while variable rates offer lower initial costs, frequently ranging between 4% and 14%.

• Borrowing Range

Small business loans can start as low as £5000- £25000.

Commercial property mortgages have a minimum limit of £50,000-£250,000.

Large-scale loans can exceed £50M.

What are the Different Types of Commercial Mortgage?

• Owner-Occupied Mortgage

This standard commercial mortgage type is designed for businesses purchasing their own trading premises, such as offices, retail or industrial units.

• Commercial Investment Mortgage

Tailored for investors or landlords looking to buy or refinance a property, this is let out to third-party commercial tenants.

• Bridging Finance (Short-term Loans)

Bridging finance provides immediate, fast-acting, short-term loans to bridge funding gaps. It is ideal for businesses looking to move quickly on property deals, while waiting for long-term finance to clear, auction purchases, or refurbishment.

• Commercial Buy-to-Let

This mortgage type is specifically designed for limited companies or businesses interested in buying commercial real estate to lease to third parties (office, retail, healthcare). It allows investors to generate income while benefiting from long-term property appreciation.

• Development Finance

It is a short-term loan; specialised funding for building newer constructions, or renovating existing properties, with borrowing based on the Gross Development Value (GDV).

How Does Commercial Mortgage Work?

Approval Requirements 

Lenders conduct rigorous underwriting, focusing heavily on

• Property’s income-generating potential (rent).
• Business stability.
• Borrower’s credit history and net worth.

Documents Requirements

• Detailed business plans and financial statements.
• Existing lease agreements.
• An appraisal of the property.
• Environmental reports.
• Down payment typically ranges from 25% to 40% of the property value.
• Both fixed and variable mortgage rates for commercial property can be higher than residential units, with variable rates frequently ranging between 4% and 14%.
• Repayment structure includes amortisation over 15-25 years, but with a shorter fixed-rate term (5-10 years), where a balloon payment of the remaining principal may be due.

What do Lenders Consider?

Want to know why lenders fear low deposits? What do they really think when they see your commercial deposit?

Affordability and EBITDA

Lenders analyse adjusted net profit or EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation) to determine whether the business can repay the loan.

Trading History

Typically, three full years of audited or certified financial account statements are required, alongside current management figures.

Deposit Amount

Between 20%-40% of the property value, with 25% being the standard requirement.

Asset Type and Location

London-specific property demand is high, but specialist properties such as pubs and restaurants require higher deposits compared to standard office or industrial units.

Loan-To-Value Ratio

Most lenders prefer 60% to 80% LTV to reduce risks.

Business Plan

Evidence of future trading performance and stable turnover is crucial.

What Factors Influence the Deposit Amount?

Want to know what things can impact your deposit amount?

• Specialised, purpose-built or older properties often require higher deposits (up to 40%) or more due to lower liquidity, compared to standard offices.
• Commercial properties in high-risk sectors, such as health care facilities, necessitate larger deposits to mitigate lender risk.
• A strong trading history, high net worth, and good credit score can reduce the required deposit.
• Conversely, new businesses or poor credit history lead to higher deposit requirements.
• Lenders typically set a maximum LTV. A lower LTV(higher deposit) leads to better interest rates.
• Lenders scrutinise the source of the deposit to prevent fraud and ensure it does not come from high-risk, unverified, or prohibited sources.
• If the property is investment-based, a higher projected rental income, relative to the loan amount, can influence a lower deposit requirement.

How to Reduce Your Deposit?

Struggling to raise a commercial deposit? Whether you are a startup owner, a self-employed entrepreneur, a multi-unit rental investor or an owner-occupied business, we have good news for you.

• If your property is low-risk, such as modern, green, compliant buildings, some lenders may offer lower deposits.
• You can refinance existing assets to release capital from existing properties and fund the deposit for a new purchase.
• Short-term bridging loans can be used as high LTV bridging solutions to secure a property.
• Offer additional security, such as a personal guarantee or a second charge on another property, which can convince lenders to lower their deposit requirements.
• Partner with an investor to help fund a project in exchange for equity in the property.

Commercial Mortgage Rates in London

• Commercial mortgage rates in London currently start from approximately 5.24% for specialised products, with many lenders offering higher rates, depending on the property value and the risk involved.
• Specialist lenders’ starting rates are around 2.24% to 6.39% for standard commercial and semi-commercial properties.
•  Variable rates are often calculated as the Bank of England’s Base Rates (3.75%) plus a lender’s margin, with some reversion rates around 7.75% (BBR + 4%).
• Typical maximum LTV for commercial properties is around 65% to 75%.
• 5-year fixed rates on semi-commercial properties range from roughly 6.73% to 6.94%, depending on the fee structure and LTV.

Key Considerations for London Property Mortgages

• Due to high property values, even a 10% deposit can require substantial funds (£56,000+).
• In competitive, high-value areas, buyers often aim for 15%-20% or more to secure loans.
• Lenders are increasingly using a business’s net operating income (NOI), instead of LTV ratios, to structure deals, allowing for lower cash deposits.
• In 2026, energy-efficient properties (green-compliant) are favoured, which may influence better financing terms and lower deposit requirements.

Conclusion

Commercial mortgages typically require a deposit of 25% to 40% of the property value. A well-placed, prime property in London can be the most sought-after, high-performing, valuable asset. Engaging an independent broker is crucial for accessing lenders that offer tailored finance solutions.

FAQs (Frequently Asked Questions)

Commercial property values can rise or fall on slight market fluctuations. Uncertainty, economic downturns, changing demand, or sector-specific challenges can reduce property value, making refinancing or selling difficult.

Loan-to-value (LTV) ratio for London properties typically ranges between 60% and 75% for standard commercial mortgages, with prime assets occasionally securing up to 80%. 

What is a balloon payment in commercial mortgages?

Balloon payment in commercial mortgage is a large, lump sum payment due at the end of a short-term loan (typically 5-10 years) and occurs when regular payments only partially amortise the principal, leaving a significant balance due at maturity.

Do owner-occupied properties require lower deposits?

Yes, if you are purchasing the property to run your own business (owner-occupied), you may find better terms (potentially 20%-25% deposit) than buying to rent out (investment mortgage).
