The issue with this logic is that
A) It just encourages house prices to keep going up. As long as people will pay the price they will keep going up.
B) In that 18 months the price of a house will probably have gone up £15k making your deposit even less.
C) The country needs people all over doing different jobs. We can't send all the poorer people up north to live and work. Its also mean to make people live North of the wall.
D) Its not addressing the core issue. Houses shouldn't be this expensive. There should be controls over rent, more houses should be built and policies that increase the price of houses should be massively discouraged.
The stamp duty holiday was mind blowingly ******* stupid and I struggle to believe that people didn't tell them it was at the time. Be understand so little about money that they think house prices going up is a good thing. Almost nobody benefits from house prices going up apart from rich landlords with multiple properties. The rest of us, homeowners included are completely screwed by the system.
