Which housing disaster?
Concrete cancer, where people ended up paying for condemned houses
Radon - where people bought houses that killed them with radioactive gas
Cladding - where people ended up paying for overpriced new build apartments that were then declared death traps that they had to pay more than the flats were worth to rectify the issue
New builds - where people paid for overpriced homes that turned out to be shoddily built, with no other amenities, no council maintenance of the roads as they were on a private estate, where the maintenance companies take extortionate fees and do nothing or the promised amenities weren't built
Buy to Let - where naive people overstretched themselves to buy more properties, hoping the rental income would pay the mortgage, without realising the area was undesirable and decent tenants would not pay to live there, legislation would change and fees, insurance, taxes and landlord licensing weren't taken into account
Compulsory purchase schemes for building that may or may not have happened (Westway A40 Corridor and HS2, looking at you) - Homes were effectively undervalued, owners weren't given enough money to buy anywhere equivalent and the homes in the area that were available to buy went up in value as there was a sudden and significant decrease in the number of properties to buy
Homes falling into the sea/succumbing to climate change
Right to buy - where eligible council tenants bought there own homes at significant discounts, but local councils were legally forbidden from using the money to buy or build more homes, resulting in a dearth of council housing and people on low incomes having to rely on private, possibly BtL landlords who are gouging the local Housing Benefit rules as far as they dare, taking advantage of lack of council overview to 'offer' substandard and sometimes uninhabitable accommodation
Elderly homeowners refusing to move from large homes to smaller homes
There is a massive shortage of affordable housing to rent or buy for any number of reasons
These issues have been building up since the 'greed is good' days of Thatcher and no one, Labour or Conservative, have done anything about it
