If the purchase of commercial housing is paid in full, you can write the signatures of two people on the contract, and you can apply for the property right certificate when you apply for the property right certificate; However, if it is a loan to buy a house, it can only be handled in accordance with the principle of whoever signs the loan, so as to ensure that the signatures on the house purchase contract, loan contract and real estate license are unified. The reason is to avoid the risk of bank loans. If you want two people to own real estate, you can apply for a * * * property certificate, that is, there must be a person's name on the real estate certificate, and the attached * * * property certificate can legally indicate the ownership of the real estate.
