How to buy building insurance
Hire a certified professional to evaluate the worth of your building.
This person will take outside factors such as location and highway access into consideration when determining the value of your building.
Make an inventory of items inside the building that must be insured.
For instance, the owner of an apartment building that supplies kitchen appliances and/or laundry facilities should have them insured against catastrophic loss. Add in floor coverings and light fixtures as well as any other amenity provided that could be destroyed by forces beyond your control.
