According to your description, your family already has 2 suites in Beijing. If both suites are 70-year-old houses, according to the purchase restriction policy, you can no longer buy a house, but you can buy a house for business and residence. If you have bought a set, signed a contract and signed it online, then the house is still in your name and you still can't buy it. Only after one of the parties has transferred ownership, can it be qualified to buy a house. I hope it helps you.
