I took a fancy to a resettlement house. Can I buy it?

Whether the demolition and resettlement houses can be bought or sold depends on whether the property rights can be registered in the real estate management department. If you have obtained the house ownership certificate, you can of course buy and sell it. Otherwise, you can't, but you can obtain property rights by "renting first and buying later".

You need to investigate the property right of the house, that is, whether all the documents are complete.
