David Newnes, director of Your Move and Reeds Rains, said: “Help to Buy has helped to infuse new energy into the UK housing market.
“The scheme has helped increase higher loan to value lending, which is giving borrowers with smaller deposits a vital leg-up onto the property ladder.
“Despite rigorous new mortgage criteria, demand for first-time buyer property will not lose steam – helped along by lower deposit requirements and affordable mortgage interest rates coupled with wage growth strengthening.
“The traditional stumbling block for many prospective buyers is saving for a deposit, but we have seen the average first-time buyer deposit fall by over £2,000 in the last year.”
