Why wouldn't anyone want house prices to fall anyway?
An older person with no children who is looking to be able to sell their property to fund long-term care?
An estate agent who makes their money from commission on the value of the house?
A Government who is gaining significant revenue from Stamp Duty?
But generally, yes, I agree that high cost of housing is a bad thing. Part of the problem around here seems to be that people are apparently unable to stay married to each other for more than 20 minutes, there are far more single-occupancy homes than there used to be, I think.
