How the commercial mortgage calculator works
The calculator takes the property price and your loan to value to work out the loan and the deposit. On capital and interest it then applies the standard amortising repayment formula, so the loan is fully repaid over the term. On interest only it charges interest on the full loan each month and leaves the loan outstanding at the end, to be cleared by sale or refinance.
The capital and interest monthly payment is the loan multiplied by the monthly rate, divided by one minus one plus the monthly rate to the power of minus the number of months. The monthly rate is the annual rate divided by twelve. Interest only is simply the loan multiplied by the annual rate, divided by twelve.
What drives a real rate on a care or supported living mortgage
A lender prices a supported housing mortgage on the lease and the counterparty. The lease length, the indexation mechanism, whether repairs genuinely sit with the provider, and the registered provider's regulatory standing and accounts all feed into the rate, with term loans indicatively from around 5.5 to 6 percent. Loan to value, typically 65 to 75 percent on a strong association lease, sits on top of that. The variable that most often surprises buyers is the valuation basis: where a lender ignores the lease and values the property as an ordinary home, the loan falls accordingly. Use the calculator to model both, then send us the deal for a real view on terms.
Worked example
On a 900,000 pound block of supported living units at 65 percent loan to value, the loan is 585,000 pounds and the deposit is 315,000 pounds. At 6 percent over 20 years on capital and interest, the monthly payment is roughly 4,190 pounds. On interest only at the same rate the monthly cost falls to about 2,930 pounds, with the 585,000 pound loan still outstanding at the end. This is illustrative only and not an offer of finance.
Commercial mortgage calculator: common questions
How accurate is this commercial mortgage calculator?
It gives a realistic illustration of the monthly repayment on a commercial mortgage from the price, loan to value, rate and term you enter. Real rates on a supported housing asset depend on the lease length, the indexation and the strength of the registered provider covenant, with term rates indicatively from around 5.5 to 6 percent, so treat the result as a guide rather than a quote.
What loan to value can I get on a supported living asset?
Indicatively 65 to 75 percent on a long index-linked lease to a substantial housing association, and less where the provider is small. The bigger variable is which value the lender uses: capitalising the lease rent, or the vacant possession value of the property as an ordinary home. Run the calculator on both figures to see the real equity requirement.
Should I choose capital and interest or interest only?
Capital and interest repays the loan over the term, so the balance reaches zero and the monthly cost is higher. Interest only keeps the monthly cost down but leaves the full loan outstanding at the end, to be repaid by sale or refinance. On lease-backed supported housing there is a specific case for amortising, because the lease has an end date and a loan that repays alongside it is structurally safer. Several lenders in the sector require at least partial amortisation. Toggle between them above to compare.
