Can I get a 100% commercial mortgage?
Getting a 100% commercial mortgage meaning borrowing the entire purchase price without putting down any deposit, is very rare, but not completely impossible. Most lenders typically require a deposit of 25% to 40% of the property’s value, since commercial lending is considered higher risk than residential lending.

Can I get a 100% commercial mortgage?
Getting a 100% commercial mortgage meaning borrowing the entire purchase price without putting down any deposit, is very rare, but not completely impossible. Most lenders typically require a deposit of 25% to 40% of the property’s value, since commercial lending is considered higher risk than residential lending.
However, there are some exceptions where 100% commercial funding may be available, usually when the borrower can offer additional security. This might include another property with substantial equity, a very strong business track record, or a low-risk property with reliable, long-term tenants in place. In some cases, a lender may consider 100% funding if the borrower is able to provide a personal guarantee or other collateral that reduces the risk.
One notable exception is in the healthcare sector, where 100% commercial mortgages are more commonly available, particularly for dentists, doctors, opticians, and pharmacists. This is because healthcare businesses are considered low risk, with steady demand and reliable income, making them more attractive to lenders.
Outside of healthcare, 100% commercial mortgages remain uncommon and typically require creative structuring or specialist lender involvement. A commercial mortgage broker can help assess whether it’s possible based on your specific situation.

Frequently asked questions
Can you get a 90% commercial mortgage?

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.
