The vast majority do want to buy in the uk as renters rights are shit, and as I pointed out, there is a need for a private rental housing sector.
We rent abroad, and I think tenants in the UK get a better deal in terms of what landlords do, than exists where I live. Yes, we will get three months notice if my landlord wants the house back, but we pay for everything that a landlord pays for in the UK, as tenants.
We end up paying for the same things twice, in the UK as landlords, as we rent out our house there, and in Europe, where we are tenants.
