The range now includes a five-year fixed rate product and a Base Rate tracker. The end dates on all the mortgage products have been extended to 30 June and all the changes are effective immediately.
The five-year fixed has a rate of 4.89 per cent until 30 June 2010. It has a £599 acceptance fee with no higher lending charges up to 90 per cent and a maximum advance of £500,000.
There is a facility to make part repayments of up to 5 per cent of the loan amount borrowed without incurring an early repayment charge for each 12 month period from completion of the loan until 30 June 2010.
Helen Shaw, group communications manager at the Portman, said: “Fixed rate mortgages have traditionally provided borrowers with the ability to budget and the security of knowing their repayments will not change should interest rates move.
“The five-year fixed rate mortgage offers an exceptionally good rate which is a clear market-leader and borrowers concerned about rate rises in the longer-term should seriously consider this deal.
“We have sharpened the rate on the Base Rate tracker mortgage again, making it an equally attractive choice.”
Rod Murdison, proprietor of Murdison & Browning, said: “Portman generally has an efficient service. However I have found myself getting increasingly riled by a growing lender trend of releasing ranges with some products available for direct business only. This puts us, the broker, in a difficult position.”
