What does it mean to buy a house and see small property rights and big property rights? Is there a difference in price?

Teacher Wang said: Small property houses cannot be divided into property rights. As far as we are concerned, we can't do real estate licenses. Usually sign a house lease contract, usually 30-50 years; The price is cheaper than that of commercial housing, but because there is no property right certificate, it is impossible to buy or sell, usually for its own use or re-lease.

Large property houses can be divided into property rights, handle real estate licenses, and sign commercial housing sales contracts. The residential property right is 70 years, and the non-residential property right is generally 50 years. The price is high, but because of the property right certificate, it can be traded, used for personal use or rented for profit.
