What are the disadvantages of a commercial mortgage?
While commercial mortgages can provide long-term ownership benefits and help businesses build equity, they come with several notable disadvantages. One of the biggest barriers is the large deposit requirement, usually between 0% and 40%, which can tie up a substantial amount of capital that could be used elsewhere in the business. The interest rates on commercial mortgages are typically higher than those on residential or buy-to-let mortgages, reflecting the greater risk lenders take on. In addition to that, borrowers often face higher upfront fees, including arrangement, valuation, and legal costs, which can make the initial setup quite expensive. The application process itself tends to be slower and more complex, often taking 6 to 12 weeks, and requires extensive documentation, financial scrutiny, and legal due diligence. Most commercial mortgage products come with variable or short-term fixed rates, which can lead to uncertain monthly repayments, a potential issue in times of rising interest rates. For owner-occupiers, there is the added risk that if the business struggles or defaults on payments, the property could be repossessed, potentially disrupting operations. Some lenders may also ask for personal guarantees, putting directors’ or owners’ personal assets at risk. Finally, commercial property is subject to market fluctuations, so if property values drop or it becomes difficult to secure or retain tenants (in the case of investment properties), the borrower could face reduced equity or rental income, impacting the overall return on investment.

Frequently asked questions
Can you get a 90% commercial mortgage?
Yes, 90% loan-to-value commercial mortgages are possible, but only in limited sectors such as healthcare properties, pharmacies, or certain convenience stores with strong trading history. For most other commercial properties, maximum lending is typically capped at around 70% to 75% LTV.
What is a commercial mortgage?
A commercial mortgage is an asset-backed loan secured against commercial, semi-commercial or large-scale investment property. Lenders assess it on income sustainability and asset risk rather than personal income multiples, and pricing is set case by case, usually as a margin over Bank Rate.
What is commercial lending?
Commercial lending refers to loans secured against property used for business purposes, such as offices, retail units, or industrial premises. Terms, rates, and deposits are individually assessed and typically differ from residential mortgages.
What is a commercial bridge?
A commercial bridge is a short-term, property-backed loan used to purchase, refinance, or stabilise commercial or mixed-use property when a standard commercial mortgage is not immediately available. It is exit-driven, typically runs for 3-12 months, uses rolled-up interest, and is repaid through sale or refinance rather than ongoing affordability.
What is a semi-commercial mortgage?
A semi-commercial mortgage is a loan on a property that combines commercial and residential parts, such as a shop with a flat above, and is also called a mixed use mortgage. Lenders assess the combined rental income, the residential proportion and the commercial tenant's lease, or the business where the owner trades from the premises, and it is usually arranged with commercial or specialist lenders. A loan to an individual or trustees is a regulated mortgage contract where at least 40% of the property, measured by floor area, is lived in by the borrower or a related person; otherwise it is usually unregulated business lending.
