Understanding your Portsmouth commercial mortgage estimate.
The calculator above models a standard amortising commercial mortgage at the LTV, term and rate you set. Actual terms depend on the property type, the lease (for investment), your trading history (for owner-occupier), and the lender selected from our 90+ lender panel. Indicative Portsmouth rates currently sit at 6.0-9.0% pa.
Loan-to-value (LTV)
LTV measures the loan as a percentage of the property value. Most Portsmouth commercial mortgage lenders cap LTV at 65-75% for owner-occupier and investment deals, with semi-commercial reaching 75%.
Debt-service coverage (DSCR)
For commercial investment mortgages, lenders typically need DSCR of 130-145%, annual rent must cover the annual mortgage payment by at least that margin.
Term and amortisation
Commercial mortgages typically run 5-25 years. Owner-occupier deals often choose capital + interest over 15-20 years. Investment deals frequently choose interest-only with a refinance at term.
Interest rates
Portsmouth commercial mortgage rates currently sit at 6.0-9.0% pa. High-street lenders (Lloyds, NatWest, Barclays, Santander) sit at the lower end for prime cases; specialists (Shawbrook, InterBay, Cynergy) cover semi-commercial and HMO blocks.

How Portsmouth property buyers and investors use this calculator.
The calculator is most useful at three points in a deal: when you're sizing what you can borrow against a target property; when you're comparing repayment vs interest-only cost over the life of the term; and when you're stress-testing what a +1% rate move would cost on your monthly payment.
For owner-occupier deals, model the LTV around what your business can support on a 15-20 year repayment basis. For investment mortgages, drop the rate to interest-only and compare to your annual rent, the gap is your DSCR cushion.
For portfolio refinances covering 5+ assets, model the blended LTV first then call us, portfolio underwriting prices differently than per-asset, and the calculator tells you where the headline number lands but not where a portfolio lender will actually price.
