I think thats a pretty phenomenal pickup.. I was in the RE industry for a while, and REFI is obviously the lingo used. .BIZ extension will hurt the value, but i think its a site you might want to develop. As far as an appraisal goes, it all depends on finding the right end user. I would say low xx wholesale. Goodluck. IMHO..... start Emailing mortgage companies. Search for the heavy hitters...
