Second, the second-hand housing market is still high, with more than 2,500 after 1998, and the residential buildings are dilapidated, and there is no property management (such as recreation or Cuiyuan), unless of course you buy a top floor. The price of a slightly better residential area (with property, water, electricity and gas) is also equivalent to a new property.
About the intermediary, the general intermediary is almost the same, mainly because you look at the house rather than the intermediary, and they usually charge a service fee (a few percent of the house price), which is almost the same.
4. Second-hand housing loans, first of all, you must ensure that you are an account in Kaifeng city or Kaifeng area (regardless of whether you have delivered the goods before), so the chances of successful payment will be greater. If you don't pay the down payment, it will be miserable if you can't approve it.
These are just personal suggestions. If you want to buy a house, you must come back and see for yourself. You must read more books to buy a satisfactory house.
I wish you an early wish.
