I have a praticular desire to see the BTL's suffer. My last house was a period terrace in a lovely street in the centre of Leamington Spa. That was until a developer bought the workshop at the end of the road and converted it into 8 terraced houses. Great, we thought, as the workshop was pretty run down. However, all 8 houses were sold to BTL's who promptly filled them with students. Completely destroyed the street, and probably cost me £10K when I sold up earlier this year.
Anyways, what goes around, comes around. I hope they enjoy the rising mortgages, falling rents and tracking the 'value' of their investment.
