Just quickly looking Merc 3 properties empty/up for sale in Hazelmere to start and that is just a quick look on one website (Mike Rogerson) One thing you highlight is "what of those who live in their parents homes now and, in a few years, will have jobs, families and such - and parents still living - an want their own home in their home town?" They may want to live in the area but will they work in the area, socialise in the area? Personally I think not because there is no decent shopping provision only Morrison or Tesco, no industrial work (I mean warehousing, factory work, etc. before anyone goes "christ he is on about the pits again") Why I think that because there is no plan for Business or industry, thus people will be drawn away closer to where they work when everything rises in price (which it will), which is sadly out of the town.
