How the semi-commercial mortgage calculator works

The calculator takes the value of your mixed-use property and the loan to value to set the maximum loan, then the difference between value and loan is the deposit you fund yourself. On a £500,000 shop with a flat above at 70 percent loan to value, the loan is £350,000 and the deposit is £150,000. Loan to value on a semi-commercial asset typically runs up to 70 to 75 percent of value, with the rest covered by your deposit.

How the monthly payment is calculated

On interest only the monthly payment is simply the loan multiplied by the annual rate and divided by twelve, and the full loan is still owed at the end of the term. On capital and interest the calculator uses the standard amortisation formula, so each payment clears a little of the loan as well as the interest and the balance reaches zero at the end of the term. Interest only keeps the monthly cost down; capital and interest costs more each month but leaves nothing to refinance.

From estimate to a real semi-commercial mortgage

These figures are a starting point. We are a finance arranger and introducer, not a lender. A real semi-commercial mortgage is sized on the valuation, the split between the commercial and residential parts, the rent and your profile, and we place it with the specialist lenders and high street banks that back mixed-use property. Semi-commercial finance for business and investment borrowers is unregulated lending, outside the FCA's regulated mortgage perimeter. Where an individual borrower will personally occupy the residential element, the loan can fall under FCA-regulated rules, and we refer those cases to a regulated firm.

FAQ

Semi-commercial mortgage calculator: common questions

What is the deposit for a semi-commercial mortgage?

Most semi-commercial mortgages run to 70 to 75 percent loan to value, so the deposit is typically 25 to 30 percent of the property value. On a £500,000 shop with a flat above at 70 percent loan to value, that is a £150,000 deposit and a £350,000 loan. A stronger asset, a lower loan to value or a clean rental profile can move the figure within that band.

How much mortgage can I get on a semi-commercial property?

The starting cap is the loan to value, so up to about 70 to 75 percent of value on a mixed-use asset. A second test then applies on investment deals: the combined commercial and residential rent has to cover the interest at an interest cover ratio, commonly 125 to 140 percent stressed. The maximum loan is the lower of the loan to value cap and the figure the rent supports, which is why we run both tests before quoting.

Can an older borrower get a 20 year semi-commercial term?

Often yes. Semi-commercial finance for investment and business borrowers sits outside the residential age caps that worry some applicants, and terms of 5 to 25 years are common. Lenders look at the asset, the rent and the exit rather than the borrower's age in isolation, and limited company structures remove the personal age question on many deals.

Is interest only or capital and interest cheaper on a semi-commercial mortgage?

Interest only keeps the monthly payment lower because you only pay the interest, but the full loan is still owed at the end of the term and has to be refinanced or repaid from a sale. Capital and interest costs more each month but clears the debt over the term. This calculator shows both so you can compare the monthly payment and the total interest side by side.
