How to Use a Secured Business Loan to Buy Commercial Property

When a UK business wants to acquire commercial premises or release equity from a property it already owns, a secured business loan and a commercial mortgage both use property as security. Understanding which product is more appropriate, and when, can save significant cost and time.
How a secured business loan differs from a commercial mortgage
A secured business loan uses property as collateral but is structured more like a conventional loan with a fixed term (typically 1-7 years) and fixed monthly repayments. The process is generally faster than a commercial mortgage and the product is more flexible in its use of funds. However, rates are typically higher than commercial mortgage rates because the term is shorter and the product is not designed specifically for property acquisition.
A commercial mortgage is specifically designed to finance the purchase of or investment in commercial property. Terms run from 3 to 25 years, LTV ratios go up to 75-80 percent, and rates are lower than secured business loans because of the longer term and property-specific underwriting. Commercial mortgages take longer to arrange (typically 4-8 weeks) and require more documentation.
When a secured business loan is the right choice for property
A secured business loan is appropriate when speed is a priority and the business cannot wait 6-8 weeks for a commercial mortgage. It is also suitable when the property acquisition is part of a broader business purpose (for example, buying a competitor's premises as part of a business acquisition) and the lender needs flexibility in how the facility is structured.
Secured business loans are also used as a bridge to a commercial mortgage: the business acquires the property quickly with a secured loan and then refinances to a commercial mortgage once the property meets the mortgage lender's requirements or the urgency has passed. This adds cost in the form of the interim financing, but can be the only practical route in a competitive situation.
"Property-backed lending gives UK businesses access to the largest amounts at the lowest rates available in the market. The question is whether the timeline and cost of arrangement fit the specific opportunity."

What lenders assess for property-secured lending
Lenders assess the property value (requiring a formal RICS valuation), the loan-to-value ratio, the business's ability to service the debt from trading income, the nature and condition of the property, and the purpose of the loan. Commercial properties with strong rental income or owner-occupier businesses with consistent turnover are viewed most favourably.
First charge means the lender has first priority over the property proceeds if it is sold or repossessed. Second charge means there is an existing charge (usually a mortgage) on the property, and the new lender takes second priority. Second charge secured lending is available but carries higher rates because of the subordinated risk position.
Typical rates and amounts
Secured business loans against commercial property are typically priced at a margin above the Bank of England base rate, with total rates ranging from approximately 5 to 12 percent APR depending on LTV, term, credit profile, and property type. Amounts start from 25,000 pounds and go up to 25 million pounds or more for commercial property with strong rental income or substantial equity.
Arrangement fees of 1-2 percent are standard. Valuation fees, legal fees, and potentially survey costs add to the upfront cost. Always model the total cost of the financing against the value being unlocked before proceeding.
