Is LOFT a 40-year commercial property right or a 70-year residential property right?

The basic property that can be made into a LOFT is a commercial house, with the longest property right of 40 years (the highest reason is that some land is bought early and developed late, so if you are ready to buy it, you must look at the service life of the plot). Property rights are generally calculated according to the bottom area of the house inside+the pool area, and the later-renovated jump floor is not included in the property rights area (the jump floor is usually decorated by itself or contracted by KFS after purchase, not the structure of the building itself). Many duplex houses are of the nature of ordinary houses, with the highest property right of 70 years, which is divided into two floors. Property right is calculated by two-story area+pool area, and its structure is the structure of the building itself, so it is counted as property right.
