I have always wondered. Could someone from a cheaper part of the country go there, get a job and just live in a van for a year or so while making a high salary? Then go back home with a load of cash.
Thing is if you only have 1 property you don't benefit from a rising property market unless you move elsewhere or sell at peak, rent during recession then rebuy... which would be pure luck.
A house is a place to live if you own one so don't worry about the paper value. If you are renting you are fucked if live in an area with rising prices - which is happening here, but I own house now thankfully.
BigRo - if he sees this - saw my old place I was renting 2 years or so ago. Total shithole, poorly made, well located. €800/month rent (worked out to half that cos got a year free when property was dispossessed but that was market value). It is now €1100 for that piece of shit, per month. Bit of wood and brick with poor construction, mice and no insulation. Cheaper to buy if you can but you need around €80k savings to even meet minimum deposit requirements for a mortgage here - hard to do when paying high rents.
