I'm assuming its the same situation in most/all university towns/cities, but where I live there are dozens, nay, hundreds of To-Let signs in almost every street. These are Houses of Multiple Occupancy (HMOs), which ALL used to be family homes. The University here has in recent years built new Halls of Residence, but they are too expensive and so some lie empty. (I know at the end of last academic year, two whole blocks lay unoccupied). The Uni here is seen by many of the city residents as being the cause of all the housing ills, and they may have a point. Every time we read a pub, hotel or shop has closed or a plot of land becomes vacant, in goes an application for "student accommodation". The town is at saturation point with HMOs. The council is in the usual "no money" situation, with more refuse/rubbish being generated by HMO dwellers, yet landlords pay no or little council tax. Consequently almost all housing stock is now HMO with nowhere for youngsters to buy or even afford. The town is an absolute mess with rubbish everywhere you look. Basically, the town has become a campus and I'm certain it's not alone.
