Can non-standard units buy and sell normally?

First of all, to answer your question, non-standard units, that is, non-standard units, can buy and sell normally and have real estate licenses.

Non-standard apartment is non-standard apartment, that is to say, for example, a building is full of one apartment, and a few different apartments are non-standard. It's just that the pattern and area of the house are different, which does not affect the sale and transfer.
