Hud Homes

I don’t know if you guys have much experience with HUD homes and the bidding process, but this is what I know. THere is some type of matrix that HUD uses to establish what price they will accept. Now the entire auction system is done a computer so wether an offer is accepted or rejected is based upon parameters pre-set into the computer. Does anyone have any idea of how the parameters are setup because I have seen some incredible deals happen in Ohio. Some of the properties are selling at 50% the appraised value and others will not. I can not seem to find a pattern. I talked to a lady who works for the managing law firm and she confirmed there is a matrix setup by HUD but she cannot disclose that information. Has anyone been able to find a pattern?
