They are a neutral, third party facilitator.  

If you do go the HML I would definitely pay to get a broker to facilitate the process which will like cost an additional 1-3 points but will make sure it closes. 

I have gained lots of knowledge from all the great forum posts that this site facilitates.

I have been calling title companies for the last two days and no one facilitates double closings (that I can find).

Second what Marco Santarelli said, above - we're complete turnkey (including management and exit strategies, all done in-house) - and the vast majority of our clients are diversely hedged all over the world - they wouldn't dream of trying to manage anything themselves - they do bottom lines and executive calls, and are quite happy to remain in this position, entrusting the ongoing sourcing, facilitating and managing of deals to reliable contractors like ourselves.Takes all sorts, I don't think there are any concrete rules about who uses turnkey and why.

btw: Quickbooks will facilitate this for you.

The realtor who facilitated the purchase of my house, and the rehabber who fixed it up.  

It also lets users see how their activity is connected to how busy their profile is, and since this is a site designed to facilitate networking, we wanted to make that connection more obvious.

It’s critical to build a community for yourself as a Note Investor.This community will serve you through time with deal flow, vendor resources, strategies, due diligence & workout support…you get the point.In my opinion a MMG needs to holds the following to be successful:1)A series of consistent meetups in-person & through video conferencing (i.e. once a month)2)Have a veteran player facilitating the call to help move the discussion along while they smell out opportunities3)Have a safe and open environment so nobody feels dumb bringing up any topic for discussion4)Synergy formation through positive discussion.This could lead to forming buying partnerships, teaming, shared resources, and a whole host of other positive moves5)NO SELLING POLICY.The MMG should not be a forum for selling products and services to each other.Any one else have any thoughts on this?

Get some third party price opinions and then get a lawyer to facilitate the transaction for you.
