What should I do if I signed an apartment building contract when I bought a house and actually changed it into an office building when I handed over the house?

First of all, apartments are divided into business apartments and public welfare apartments. Business apartments are divided into residential, mixed and hotel. Residential apartment land belongs to residential land, with a service life of 70 years (50 years in some places); The land category of mixed apartment belongs to the comprehensive land use life of 50 years; The land category of serviced apartments belongs to commercial land, with a service life of 40 years.

If the residential apartment is going to do business office, it means that we not only have to bear the deed tax as high as 3%, but also bear the future commercial water, electricity, heating and property fees. Even if the property right expires after several decades, the state will recover it free of charge and has no right to renew it. In case of demolition, we don't even have the right to take compensation for demolition.

Personally, I suggest that owners need to get together to consult lawyers and feel that they should take the road of safeguarding rights.
