Generally our goal is to maintain the existing sq footage and simply move a wall or two which doesn't always yield the highest ARV but it's quicker.

You can also look for other signs of potential cost or value, such as illegal square footage, large garages, or huge yards.Now it’s on to the neighborhood.

The one that can be seen on the page is that the average square foot is larger and larger homes tend to have smaller square footage price.  

You want to compare apples to apples, not apples to bananas.Calculate what the SELLING COST PER SQUARE FOOT of each of your comps was (as opposed to the listing price per square foot), then multiply the square footage of your subject property by the AVERAGE cost per square foot of the comps.  

For each of these, divide the Sales Price by the Square Footage, of Living Space.

types of homes: 4/3/2 bed, 2/1 baths, garages, sq footage, lot size/acreage, etc.
