When I first saw this story I assumed the development was somewhere like Solihull, where you expect the residents to be NIMBYs. I nearly fell off my chair when I saw the houses were in Netherton! Now there is nothing wrong with Netherton, but it is a typical Black Country town with a lot of Victorian terraces in poor condition, post-war council housing estates and pockets of new developments on brownfield sites, interspersed with small factories (often metal working), small industrial estates and warehouses.
How these new home buyers must have lapped up the advertising from the developers " Contemporary waterside living" - next to the canal, inevitably complete with rats, "Great transport links to Birmingham" - slapbang in the middle of the West Midlands conurbation with miles of gridlock in every direction at 5 o'clock every evening and you can imagine the drawings of beautiful children playing under trees next to the gorgeous houses.(No sign of the major road running straight past though!) They were sold the dream by the developers, by the telly and by the papers. Own your own home and you will suddenly be in this glamorous new world.
Then down to earth with a bump, because once you come out of your shiny new front door I am afraid you still live in the same old town with its mixture of people, poor and better off, council tenants and owner occupiers. This is the real world (and always has been) Its not that house prices will drop because of the tenants - it's that you overpaid for a reality that never really existed.
