Hi Stacy:
What is Arm's Length? Buyers and sellers dont know each other, not related, come from the market place, right.
If you have 3 sales, and they have been exposed to the market for a time period which is typical of your market area, and they were purchased by 3 different individuals, then I would say you have an arms length transaction.
When I do this type of appraisal, I do not limit myself to FHA forclosure sales only. We should look for the most similar and proximate sales, regardless of the seller or the motivation of the seller.
A home in forclosure is usually somewhat neglected. Can be only cosmetic neglect or can be long term deferred maintenence (sp?), or can be the object of vandalisim. In any case they tend to sell at somewhat of a discount due to the fact that they are vacant, and in some disrepair. That having been said, I would not ignore a house that sold, not in forclosure, which was more similar to the subject, and closer than one of your forclosures. You would have to make adjustments for condition, but after some good scrubbing, and lawn mowing, your forclosure may shine like a non forclosure.
Sorry wandered off the Arms Length part of your question. I dont think you have a problem. What I am saying is dont ignore non-forclosure sales.
Regards
Hal
