I can't. When individuals in Chongqing buy family housing, the down payment ratio should not be less than 20%, that is, a 4 million house needs 800,000 yuan. If the down payment ratio of the first suite of commercial loans is 20%, it needs 3.2 million yuan, and deed tax, agency fee, house maintenance fund, decoration fee and moving fee need to be considered. Therefore, it is impossible for Chongqing to buy a 4 million house with an annual salary of 500,000.
