The advice website’s figures also showed that remortgage advice enquiries dropped from 37% in March to 30% in April.
Karen Barrett, chief executive of Unbiased, said: “Last year we saw a similar “spring time” rise in searches for first-time buyer mortgage advice. This year despite three months of consecutive falls in searches for first-time buyer advice, April has seen the first rise in demand in 2012.
“Over the past weeks we have seen lenders raise mortgage rates and tighten their lending criteria, putting further strain on people wanting to get on the property ladder, which will be a contributing factor to the rise in first-time buyer enquiries.”
