I'd say around $1,000. Hardly any overture but it's a great generic in one of the highest margin industries online.
Would definitely be a candidate for development. I would follow a similar approach as Realtor.com does with real estate companies. Get your own site YourCompany.Realtor.com. I could see the same strategy working well here if you ever decide to go the development route: A1HomeLoans.MortgageFirm.com, HometownMtg.MortgageFirm.com, etc.... There are plenty of small-sized mortgage companies like this that might be able to use packaged sites like this. Just a suggestion, great name- Good luck!
