Predicting Your Likely Interest Rate & Term

The commercial mortgage calculator will offer you accurate terms, based on the information input. If the figures inputted are incorrect, then the figures will be meaningless and of little help to you.

The rate offered will vary depending on whether your property will be owner-occupied or used as a commercial investment property.

Below are a number of products that can be used as example figures for the purpose of the commercial mortgage calculator.

Owner Occupied – Clean Credit History

Owner occupied loans for clients with clean credit history tend to be priced depending on the amount of money borrowed. For larger loans, the rate charged reduces as competition between lenders to secure your business increases.

Amount Borrowed£50,000 – £99,999£100,000 – £249,999£250,000 – £499,999£500,000 – £1,999,999£2,000,000+
Interest Rate4%3.50%3.25%3%2.50%

Commercial Investment – Clean Credit History

Commercial investment rates are usually slightly higher than mortgages for owner occupied properties. Very low interest rates are still available however, especially for larger loans.

Amount Borrowed£50,000 – £99,999£100,000 – £249,999£250,000 – £499,999£500,000 – £999,999£1,000,000+
Interest Rate4.75%4.00%3.75%3.15%2.85%

Commercial Property – Light Adverse

Commercial Property mortgages for those with minor adverse credit tend to be priced according to the loan to value (LTV). This is also true other minor demerits, such as struggles with traditional affordability calculators or short-leases for investment properties.

The below rates are a guide, although the rate charged may vary, and even drop for loans above £1,000,000.

Loan to Value (LTV)55% LTV60% LTV65% LTV70% LTV75% LTV
Interest Rate4.89%5.14%5.39%5.49%5.59%

Semi Commercial Property – Light Adverse

As with the rates above, commercial investment mortgages that won’t fit the high street tend to be priced according to LTV. Again, as above, for loans above £1,000,000 we may be able to offer lower rates.

Loan to Value (LTV)55% LTV60% LTV65% LTV70% LTV75% LTV
Interest Rate4.29%4.79%4.79%5.29%5.29%

Owner Occupied or Commercial Investment – Heavy Adverse

In situations where there is heavy adverse credit in the background, or other significant factors affecting the application, a rate of 7.9-9.9% is realistic. In many cases, loans at this sort of rate will be flexible and understanding of any historic problems.

Choosing the Right Term

The term depends on several factors. Each lender will have their own rules. But generally speaking, capital repayment applications are available for terms of 3-20 years, with some lenders allowing terms of up to 25 years.

Interest only tends to be available from 3-10 years – or even beyond this subject to a small loading to the interest rate.

Borrowers in certain industries may find that the terms offered are shorter. For instance, some lenders reduce the maximum term to 15 years for retailers. This is due to the perceived strength of the sector, and therefore the risks of lending to the sector over the long term.

Capital Repayment Or Interest Only

Whether you take your mortgage on a capital repayment or interest only basis is an important consideration.

  • Capital Repayment Mortgages have higher monthly payments. This is because each month, a portion of the amount owed is repaid, along with the interest. The amount owed therefore reduces each month, with the loan being fully repaid at the end of the term.
  • Interest Only Mortgages require the interest to be paid monthly, with no contribution to the repayment of the outstanding capital. As only interest is paid each month, the full loan amount remains outstanding and must be repaid at the end of the term. Interest only commercial mortgages tend to be restricted to a maximum of 75% loan to value (dependent on sector).

Commercial mortgages are available on interest only, or full capital repayment. The number of lenders offering interest only is limited, however. This means that by excluding any repayment mortgages from consideration, you may have to pay a higher rate.

When calculating your repayments, working from the capital repayment figure is usually advised. By contacting us, or heading to our commercial mortgage comparison page, we will be able to give you an idea of costs based on your circumstances.
