I want to ask about real estate!

You can put the property right of the house in your parents' name. Your parents go to the notary office where the house is located with their ID card, household registration book, marriage certificate and house ownership certificate, and make it clear that if two old people die, the property right of the house will be inherited by you alone and has nothing to do with others. In this case, it will not affect your buying a house in other areas, and it will also clarify the future ownership of the house.
