| the comparable for each thing it doesn't have that your subject home has, and subtracting for each thing it has that your subject home doesn't have.
This sounds confusing, but it will make sense once you try it a couple times. For example, if your subject home has a second bathroom, and the a comparable doesn't, you add the value of the bathroom to the sales price of the comparable. If a comparable home has a blacktop driveway, and the subject home doesn't, you take the value away. What you are doing is rectifying differences, to see what the comparable home WOULD have sold for if it was just like yours. Suppose a comparable sold for $140,000, with one less bathroom than your subject home, and a bathroom is worth $15,000 in your area (ask a real estate agent for help with these figures). You ADD $15,000 for the bathroom it doesn't have. You subtract, say $4,000, for the paved driveway it does have, that your home doesn't have. $140,000 plus $15,000, minus $4,000 gives you a comparable sales price of $151,000.
Do this with all differences between the subject home and each comparable. Once done, average the three comparable prices. If, for example, the three comparables now have adjusted sales prices of $151,000, 162,000, and 149,000, add the three figures and divide by three. The indicated value of the home is $154,000.
All appraisal is an inexact science. You might only find comparables sold over a year ago, and have to estimate appreciation in |
