I run three vertically integrated financial businesses:
Minnesota Real Estate-http://www.selling.mn
Minnesota Mortgage Broker-http://www.ventureloanapp.com
Minnesota Financial Planner-http://www.investments.mn
Minnesota Mortgage Broker Blog-http://www.minnesotamortgagebrokerblog.com
Twin Cities Real Estate News Blog-http://www.twincitiesrealestatenews.com
I like the idea but I would be afraid of the liability. I can't believe that some overzealous attorney couldn't attribute liability to the wiki for his/her clients home not selling and therefore damages. Maybe I'm just paranoid. If you can create a wiki and have zero liability for the content posted, then I'm all for it. If there is an insurance policy for this type of thing, let me know. I think the need for more "truth in advertising" is obvious so the concept is sound.
This will be a great boost to home sellers and home buyers as it will provide a replacement product for the subprime and higher LTV conventional products which are now next to impossible to find.
