How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Subject Property Sq Ft = 2000, Comp 1 Sale Price = 350000, Comp 1 Sq Ft = 1800, Comp 2 Sale Price = 380000 = 8 input(s) provided
  2. Calculate Estimated Value
    Estimated Value = baseValue * (1 + conditionAdj / 100)
    375051 = $375,051
  3. Calculate Avg $/Sq Ft
    Avg $/Sq Ft = (comp1Ppsf + comp2Ppsf + comp3Ppsf) / 3
    187.53 = $187.53
  4. Calculate Median $/Sq Ft
    187.18 = $187.18
