Dear @creativeblue, i remember when i was young that real estate market was drived by a kind of piramidal system where there was in special tourism area like Canaria islands, S.Domingo, Baleari islands some pour people engaged to find possible customers with the promise that you could by 2 weeks of vacation every year for all life long whatever you want by this real estate piramidal system.
There was a very big affairs about it because seems that who drive this business was something connected with criminal associations and use very strange methods to convince people to buy this package even with ipnotize or give drug to make them confused and more easy to let buy it.
Of course what you are talking about is not that kind of business, but what @crypto.piotr say is something connected with it and i think house property must be keep in the hands of each government because of taxes and ownership regulations...
