I'm not sure thenQXrV
When we got married in 1968 our new house was £4,250 being a 10% deposit (I think) and a mortgage 3 times my salary. That was all that was allowed.
A few years later the government removed that constraint, so many people took out mortgages far greater than 3 times their salary. That brought about gazumping and the consequent rapid inflation of house prices.
I am afraid you are as far out of touch as it is possible to be if you think the housing shortage is overstated.
I am a landlord. On the rare occasion that i advertise a property (most are let to friends/family of existing tenants) i will receive 50 requests for a viewing within 24 hours.
I have had people crying and begging for me to rent to them. I always give NHS workers first pick but otherwise i end up putting a handful of names into a hat.. Thats the lottery of housing.
