Buy-to-let landlords who are leaving the market because of a government clampdown have been cashing in with an average profit of £80,000 for each property sold.
In England and Wales, landlords made £79,770 before tax last year, having owned the property for an average of just over nine and a half years.
In London, they gained £248,120, according to research by Hamptons International, an estate agency.
