Theoretically, yes, but in view of the current credit situation, if you want to buy a house with a loan in Tianjin. The income certificate issued by your work unit in Beijing will not be superior to that in Tianjin. And it is more troublesome. I suggest you open an income certificate in Tianjin. Some intermediaries can provide this one-stop service. It is nothing more than paying an intermediary fee, but it is worry-free. I hope you can buy a satisfactory house in Tianjin.
