Housing affordability in the South East of England. Although housing affordability across the South East is often cited as a serious concern among policymakers, this study has been commissioned by Moat to quantify the extent of the problem. We are pleased to deliver the preliminary findings of this work, with the full report to be made available in November 2014. Mortgaged home owners who are already financially stretched will struggle if interest rates rise. It is likely that a high proportion of people who cannot service their mortgages will drift into the PRS and accelerate the overall trend towards the PRS over the medium term.
