How to modify/ adjust Comps to match my subject house

[Doug Haisten]

I have had a few responses from DM and D4D. In looking at comps (recent sales using iComps, Zillow or Realtor) I truly have a hodge podge of past sales. The site iComps gives me the most past sale to refer to . The problem is difficulty in matching houses sold to the house I am working with (there's actually 3 houses in the same 1 mile radius). One of the house I am going to offer on is built in 1957, well maintained and is a 3/1 house of 1400 sq ft. The recent sales are either over 6 months ago, are 3/2 houses or built in the 80's or 90s. There is one recent sale that is on the same street and a 3/1 but only 1032 sq ft sold almost a year ago and another 3/1 about a 1/3 mile away that is 1550 sq ft sold 7 months ago and another 3/1 1.3 miles away 1146 sq ft sold. How do I make adjustments in looking at the comps?

Thanks, Doug
