What Is A Residential Appraisal?
Sales Comparison Approach - QUICK START GUIDE
Starting with the basic "Market Approach" (cost and income approaches not included at this time), we go straight to comparing comparables to the subject property and making adjustments for the differences. Following in this page and in a number of links to other pages, I will detail much of the "Sales Comparison" appraisal process in the page below and links to other pages.
Adjustments are made for individual differences between the comparable sales and the subject property. The comparables (the sale usually less than 1 year old) are always adjusted to compare more equally with the subject property. The adjustments are added or subjected from the sales prices of the comps to derive an adjusted sales price to compare to the property being appraised.

The main adjustment principal: |
|
|
|
| Comp Difference is ...Superior |
= |
-- Negative Adjustment |
|
|
|
| Comp Difference is ...Inferior |
= |
+ Positive Adjustment |
__
Mantra: 1. Comp superior - Negative Adjustment !
2. Comp Inferior - Positive Adjustment !

The 2nd page of the URAR is where you develop the market approach "estimated value", which on most residential appraisals is the most important value. Adjustments are made on the second page of the URAR form as shown below:

The information that is in the adjustment grid comes from:
- The initial research, searching for comparables, pulling the subject tax sheet, mapping for driving directions, questions for the homeowner.
- Inspecting the Subject Property, measuring the house, taking pictures inside and out, and drawing the floor plan which is all just the tip of the iceberg.
- Inspecting and analyzing the neighbor, studying aerial photos, looking for good maintenance or lack thereof, real estate mixes, trend changes, etc.
- Choosing 6-8 comparables to drive by: taking pictures, making notes, running an MLS sheet and a tax sheet on the comparable properties, and calling the listing agent to clarify information.
- Keying in the information on the subject property, choosing at least 3 comparables for comparison in the report. Confirming data and proceeding with the report. Loading pictures of the subject and comparables, drawing the sketch on the computer, mapping the final comparables with the subject.
