The Towns are not deserted but have a history of depopulation with younger people moving away to find work and more exciting lives in bigger more prosperous cities, leaving an older demographic behind. Properties are abandoned, with the villages being owed back taxes and the properties are slowly deteriorating, becoming eyesores and dangerous. Most of these villages are out of the way, smaller, so don't expect tourism or a rental market to supplement ownership.
This has been an interesting experiment, there doesn't seem to be a landslide of successful experiences being reported so far, non-refundable deposits with very short timelines with quick starts required and completion of renovations no longer than 3 years, large expenses in paperwork, while good for the town doesn't bode well for someone actually trying to make this happen. This first wave got a lot of press and hype, lots of activity but doesn't seem like much actual property changing hands, the 2nd wave underway now seems to reflect a re-evaluation by the towns trying to sweeten the deal, some are easing deadlines, some are helping reduce the paperwork costs and red tape, they got lots of inquiries but not enough actual buyers so back to the drawing board.
