Unit in place method
Approach to valuing property based on its replacement cost. The cost of each major element of the property per square foot is added together and multiplied by the total space to estimate what it costs to rebuild the structure. Assume the cost per square foot for the following components of a building: walls - $4.50, ceilings - 1.50, floors - 2.50, other - 8.00 , total $16.50. If the total square feet are 20,000, the property's estimated value is $330,000 ($16,50x20,000).
