Expect to have your time wasted by endless people that think that Grandma's house is somehow worth 600k despite needing a huge amount of renovation.

Much better to buy from the council.
Lofts and roof spaces are still a good ploy, where you have to install water, leccy et al yourself. I am negotiating a buy in a German built block in Gdansk at 2,000 zl a sq. metre, though there are added costs re: communal renovations.......
