Adjusting comparables based on relative value to the target property

[Sean Dezoysa]

Hi everyone;

I wanted to ask if you adjust comparable property valuations based on "feel" or a more rigorous method aka:

Comparable 1 is on a main road. Main road properties average $4 less per square foot in this town.

Comparable 2 has a 4th bedroom. 4 bedrooms carry a $10 per sf premium in this area
