Demand for two and three-year fixed rate mortgages from a UK independent estate agent is now averaging 70% for the first 7 months of 2011 - up 7% on the start of the year.
What's more, demand for five-year fixed rate mortgages rose to a five month high of 7.4% in July.
Tracker mortgages proved more popular with buy to let investors, reflecting the increasing competitiveness of products in the market. haart Financial Services has also begun to see signs of a greater appetite among customers for re-mortgaging.
David Miles, Managing Director of haart Financial Services, says:
"The increasing popularity of fixed rate mortgages, particularly two and three year deals, reflects the desire for a degree of financial certainty among customers in a period of relative economic uncertainty as a whole across the country.
"We are expecting this trend to continue, particularly in light of the Bank of England recent economic forecasts for the remainder of 2011."
