It is a hard fact that this country is suffering a chronic housing shortage, and its getting worse, daily. Therefore, in the long term, the core value of all homes will increase in a free market. However, the money available to lend to home buyers nearly ran out and the reins have been pulled in. Therefore, buying power has reduced and home prices (not value) have fallen to match the limited mortgages available. Potential house buyers cannot now get mortgages, but they should have the monthly income to pay back the mortgage that they cannot now have. Houses are not now being built due to the lack of credit available to the builders to build and the buyers to buy.
The only answer to 1st time buyers, with reasonable income, is to rent. Buy To Let landlords should not be adversely affected by this credit crunch unless their tenants are not paying the rent. In fact, their mortgages should reduce while the rental income remains constant (or even increases). The landlords should sit tight; potential home buyers will take up short assured tenancies.
However, the government will now restore most of the lending power (with restrictions) and I foresee, in the new year, house prices climbing again until the housing stock meets the demand. This is the core problem that needs to be addressed. It caused the credit crunch.
