That's a problem caused by the low interest rates - it has pushed the price of houses much higher than where they should be. Builders couldn't keep up with the demand for new housing, so they increased their prices (which in turn increases the demand for older houses, thus increasing the price). Demand for builders increases, their pay increases, more kids take up the trade. 10 years time, there's enough builders to cope with the demand for new houses. So now that a house can be built on demand, the price falls (or stops increasing). If interest rates don't change in that period, housing will have become more affordable. If they rise; Firstly you'll see the price of houses fall quickly as people start to default on their loans and sell up. Secondly you'll see a bunch of young and unemployed carpenters.
