The buy-to-let market has been described as a slow motion train crash with a landlord exodus and much higher rents.

Charles Curran, principal at Maskells Estate Agents in London, said landlords will quit the market en masse as regulatory, mortgage and tax changes kick in.

He is forecasting that “high” numbers of rental properties will be disposed of between April 2018 and 2019 as the first and second tranches of capping of mortgage interest relief come into effect.

He also says that an increase in capital charges for banks under Basel will push mortgage rates up.

As a result of the exodus, rents will jump dramatically in 2018/19, and house prices will be depressed by the potential addition of 163,000 homes on the market.

Curran said: “The buy-to-let market has provided so much of the rental stock the country depends on, but the Government’s tinkering could lead to a sell-off.

“This situation does seem akin to a slow motion train crash. BTL landlords with mortgages are standing on the track in a game of chicken with a regulatory locomotive, hoping to time their exit as best as possible.

“This high-risk game will almost undoubtedly leave casualties.”
