Done right, as a consumer education web site - with links to lenders mortgage.org could be very useful.
I know how I would monetize it. Informative articles, social interaction between new home buyers their experiences with people considering buying, and even more information ... Information, information, information, which is great for seo purposes and getting ranked as people will link to true value articles .. and then the 'loan resource links' subtly put in there
Contests like get a qoute from our lenders and be entered in a drawing to have all closing costs (besides points) paid for .... Would get people to get quotes and you the CPA ... List goes on, it has huge potential, but only if developed as a resource with the commercial aspect being a 'byproduct' to 'help cover server costs' as far as the surfer is concerned.
A helpful orginization showing you what pitfalls to avoid, talking about the status of the housing market, links to realtors (paid listings for big cities) - The list goes on ... Gotta think outside the box but this has potential, but if they are in the million range for the domain it will be A LOT tougher ...
Interested in seeing what that sale goes for, if it sales ..
Would love the ability to develop that - it would be a very fun site to develop with the right resources !
