First of all, such a house has low property rights. General housing ownership is 70 years, which can be automatically renewed after expiration, while commercial and residential dual-use housing ownership is only 40 to 50 years, which cannot be automatically renewed after expiration and must be supplemented. This is no different from renewing a long-term lease.

Secondly, the cost of water, electricity and public maintenance funds of this kind of property is relatively high. Because the water and electricity prices of commercial and residential dual-use houses are subject to commercial standards, which are higher than the general living standards; Moreover, property charges are rarely restricted by government departments, and there will be mixed situations; The public * * * maintenance fund also shares all parts of the maintenance with the merchants. These reasons lead to the high cost of commercial and residential dual-use houses in daily life.
