You can buy a house and get a marriage certificate. These are the same as general independent permanent residence.
However, some collective accounts do not allow children to enter the house, and some can, depending on the situation, which is different from permanent accounts. General accounts are linked to real estate!
It is easy for you to move back to your hometown! Because you are from your hometown, you should first go to the household registration department of the public security organ of your hometown to issue a certificate, that is, you are allowed to move in.
Then move out to the police station where the current account is linked. During this period, you may need the proof of the registered permanent residence affiliated unit to let you go, which is also very easy to handle!
My situation is similar to yours!
Alas, China's household registration management system is really rigid! Trouble.
