Well, your asking for an appraisal on a developed site, thats a whole different kind of story. However, in general right now - refinances are becoming more and more crucial especially with so many people having takin out very poor loans the past few years to get in on the real estate boom.
These people are hurting right now with adjusting mortgages and very soon are looking like they will need to refinance (if they can).
I suspect the domain alone is worth a few hundred atleast, however if you factor in the revenue that the site generates, you could be looking at upwards of 12-24 x revenue....
$100k ish...
