content: My question is if these building only stand max 10 years what does the process look like on the tailing end.  Do people just play chicken with these buildings or does the government condemn it and boom, your property is worth zero? I don't get why these people are talking about the property apreciating.  With such a narrow window it's much more like a car.  I just lost a car that lasted more years than those buildings and every one should be in agreement that an investment that breaks down in 10 years will depreciate. Speaking of socks I bet the concrete is more sand than anything else.  Throw in those socks and you've got stabilized earth with a little bit of binder.
