How to calculate the housing appraisal price?

Appraisal method of house appraisal: Calculate the complete replacement value (original value) of the house according to the total building area (square meters) and the measured replacement unit price, and calculate the present value (net value) of the house according to the appraisal degree of the house. The calculation formula is as follows:

Total value of housing replacement (original value) = total construction area × housing replacement unit price+housing increase or decrease value.

Present value of the house (net value) = complete replacement value of the house (original value) × appraisal degree of the house (%)

Accrued depreciation of house = full replacement price of house (original value)-present value of house (net value)

Annual depreciation amount = full replacement value of the house (original value) ×( 1- residual value rate) ÷ service life.

Annual depreciation rate = annual depreciation amount ÷ complete replacement value (original value) × 100%.

The serviceable life = the durable life of the house × the old and new degree of the house being evaluated (%)
