Affordable housing is equivalent to the government subsidizing some money to households to solve the housing problem. So, you can only live on your own. If it is sold, the nature will change and the government will not subsidize it. Subsidies to families will be returned to the government. That's what it means.

If you sell 3000 yuan/square meter of affordable housing now, a set of 100 square meter house will cost 300 thousand yuan. Five years later, the price of affordable housing will rise to 5000 yuan/square meter, and your house can sell 500 thousand yuan. At that time, you bought the house for 300,000 yuan, deducted 300,000 yuan, and then deducted half of the 654.38+million yuan from 20 Wan Li to give it to the government, which means you have to give it to the government.
