I did talk to Don R. at DHM and listened to his whole sales pitch. I think they are legit, and they offer an incredible amount of tools. A couple things have changed though (and not in their favor). The buy-in member price is now $3495, and that is NO LONGER A DEPOSIT. That's a huge shift from their prior business model.
That being said, if you need the 100% cash-to-close model to get the ball rolling, and you can find a deal that will net you $25k plus or more, this may be the only path (assuming you can pay the member fee and can't find any other HMLs that offer the services they do w/o a member fee). The $650 local site visit and eval I don't think is a bad thing as this confirms that it's a good deal. Anyone should be able to do a pretty thorough analysis of any deal with BP calculators before you'd even put a deal in front of DHM.
I know there have been complaints however they do have a great BBB rating too. Would love to hear other thoughts as well!!
