Let me answer it for you:

The so-called "special purpose" houses in the real estate management regulations are other buildings that are different from ordinary residences. They mainly include:

1. Office use refers to offices (buildings) and other land and buildings directly used for office use;

2. Teaching use refers to classrooms (teaching buildings) and other areas directly used for teaching. Land and houses;

3. Medical purposes refer to outpatient departments and other land and houses directly used for medical treatment;

4. Scientific research purposes refer to places for scientific experiments and Other land and buildings used directly for scientific research;

5. Military use refers to land and buildings used for military facilities and their ancillary facilities, including:

Above-ground and underground military Command combat engineering;

Military airports, ports, and docks;

Military warehouses, camps, training grounds, and testing grounds;

Military communications and navigation , observation stations;

Other land and buildings directly used for military facilities.

If your house belongs to one of the above special purposes, please fill in its specific purpose; if your house is an ordinary residence, there will be no special purpose marked on the property certificate.

Special-purpose houses are owned by the state and cannot be mortgaged.
