Steve Seal, managing director at Bluestone Mortgages, said: “It’s encouraging to see that the number of property transactions has remained at a healthy level as the market continues to recover.
“House prices are now experiencing a substantial boom, with the stamp duty holiday and demand for remote-work-appropriate properties both helping to fuel the market’s rebound.
“Rising house prices have, however, been detrimental to first time buyers, pushing their homeownership aspirations even further out of reach.
“Many younger borrowers have also experienced a financial setback during the crisis, which has only compounded the problem.
“As a result, demand for specialist mortgages is expected to rise among this cohort when they consider the lending options available to them.
“The specialist market must prepare for this increase, and lenders and advisers will need to work together to capitalise on the opportunities coming their way.”
Guy Gittins, chief executive of Chestertons, added: “May continued the exceptional transaction volume we have seen throughout the entire year with three times more buyers than usual.
“Viewings have been at a five-year high for the past three months. This has led to competitive bidding but with supply meeting demand, large price increases have been kept at bay.”
Gareth Lewis, commercial director of MT Finance, said: “The busiest May since 2007 is partly down to the lack of transactions last year, thanks to the pandemic, and the stimulus that the stamp duty holiday is giving the market.
“It is too early to say whether sentiment is such that we are now on a continuous upwards trend or it is a blip.
“However, on the positive side, people are looking to transact and are buying property. Even though there are still numerous people on furlough and many sectors are not working as they should, there is still confidence there.
“Until we get out of the other side of all this, and don’t have the stamp duty holiday and other stimulus, we won’t know exactly where we sit. Only time will tell if the market falls off a cliff.
“At some point, the government needs to think longer term and address issues such as the lack of affordable housing.
“This has been pushed down the line by COVID and we are not likely to see anything until next year at the earliest.”
