The buy-to-let sector has, however, been particularly vulnerable in the current
recession. There was a significant expansion of capacity in major city centres to
the point where there was probably overcapacity.
This undermined prospects for rental growth and when interest rates started to move,
profit margins got squeezed or disappeared. Much of the buy-to-let was for investment
purposes supported by liberal lending policies of some financial institutions.
This part of the market is currently experiencing a painful period of adjustment
as rental growth has stalled and selling prices fallen.
