A man with low income—how should he respond to the woman’s demands for a house and a car when they get married?

To show your sincerity, register the house and car only under the mother-in-law’s name. You need to notify them in advance that they have a certain economic foundation and capability.
Solution: if you buy a house and a car with a 0 down payment, what if you don’t have money to make the payments? The answer is simple: the mother-in-laws—they should handle the issues they raise.
