The figures show that the average buy-to-let purchase loan increased between May and June by 1.3 per cent to £125,882. Despite this monthly rise, annually this figure was down 3.9 per cent.
Mortgage Advice Bureau head of lending Brian Murphy says: “Many key indicators for home movers and first-time buyers remained either stable or only marginally changed when compared to the previous month, although some year-on-year figures saw slightly more noticeable movements, albeit these were very much in line with data from other sources.
“As has been the case for the past 12 months or more, the regionally diverse picture continued in June, with the East and West Midlands, Scotland, Wales, Yorkshire and the Humber and the North still seeing purchase loan sizes increased on the previous month.
“However, it is a slightly different picture inside the M25. Whilst many areas of London continue to appear to be suffering from ‘Brexit fatigue’.”
