This paper examines the time-series properties of house price to earnings ratio (HPER) in the UK using aggregate and regional data. Specifically, we utilise a series of unit root tests to examine the null hypothesis of nonstationary HPERs. These include linear tests as well as a nonlinear test and also a test which accounts for abrupt structural change. The results are against the notion of stationary HPERs. This implies that house prices may permanently diverge from earnings.
