I've bought property in Lodz but I'm living here and I'm hoping to keep the property until well into my retirement rather than flogging it off in 5 years' time. I sure as Hell don't want the other flats in my area bought up and filled with foreign workers who contribute nothing other than (some) money to the local community.
I am well aware of the situation in Lodz, my girlfriend lives there, we all know what the level of earnings are. I have bought these properties partly because I need somewhere to live because I am there for one week in every four, and partly for long term investment - but I don't have to justify that to anyone.
Regarding the property market in the UK. You are wrong. The market is driven by supply and demand, we have greater demand than supply, driven by more people living by themselves, people living longer, divorces and net influx of people to this country. Mass property acquisitions by French is unheard of and the Russian's - will yes there are some high profile billionaires that have bought here but really I don't think that will effect me. Oh - I do have 30,000 Polish people living in my town - that may have any effect - but good luck to them
