Provisions for commercial and residential use: 1. Commercial and residential dual-use houses cannot move into hukou, which means that even if there are good educational resources around, children can't go to school nearby because of hukou. 2, there is no complete life supporting service facilities. Commercial projects generally do not need to design supporting service facilities, such as schools, businesses, neighborhood committees, etc. In other words, there are no supporting kindergartens, schools, medical care and old-age care services. This will bring a lot of inconvenience to daily life after purchase. 3. Mortgage loans are based on commercial housing standards. The down payment for commercial and residential dual-use houses is 50%, the loan interest rate is 1. 1 times that of ordinary houses, and the loan period is at most 10 years, so housing provident fund loans cannot be used. 4. Do not implement preferential tax policies when purchasing. There are many preferential tax policies for ordinary houses, but there are no corresponding preferential tax policies for commercial and residential houses.
