Quote from Picaso:
Haven't heard about this in Spain, do you have a link/source? Thanks
[What I've read about is banks taking possession of developers' unsold properties and renting them out with a purchase option (i.e. have a 5-year window in which the tenant can decide to purchase the property and have the money paid in rent deducted from the property price). This was common in the 90's too.]
got it from a trader in L/S hedge fund, I know the guy and seems quite reliable
