Credit crunchy

One wonders what the effect of the so called 'credit crunch' will have on social housing.

It would be interesting to do some research on whether those who purchased their social housing through the right to buy have disportionately more sub prime mortgages than other house buyers and will therefore be at more risk when the fixed term ends. I have a feeling a lot of right to buys were funded with dodgy sub primes.

On the flip side as sub prime mortgages are harder to get what effect will this have, if any, on the amount of social housing lost through right to buy?
