What factors determine the value of a used modular building?

The value of a used modular building is determined by several key factors. These include the original purchase price, the year the building was manufactured, and how many years it has been in service. Depreciation is typically calculated over a 15-year schedule, with a minimum residual value for well-maintained units. The building’s physical condition—rated as excellent, good, fair, or poor—also affects value, along with floor plan features such as bathrooms, kitchens, HVAC systems, and private offices. Building size and layout, market demand, and location all play a role in estimating a realistic resale, donation, or insurance value.
