Very easy to use and a nice interface. 

Sounds like the FSBO seller hasn't figured out the Zillow interface.

Regardless it would be wise to interface with your potential QI now since they must be in place prior to the sale if you continue with a 1031.

They are inexpensive and seem to have a nice interface. 

The capabilities I need in place are:CRM (Customer Relationship Management) system able to interface with listing management softwareDeal analysis software capable of producing cash flow projections, DCF analysis, ROI calculations, etc.Customizable marketing solution that creates external materials to distribute to customers and clients (created automatically based off listing)Project management tracking that interfaces with CRMMaximum exposure for our listingsMaximum exposure for our company brandI have been analyzing the following software, but I know there are many others out there:Costar, RealNex, Salesforce, Commercial Search, CIMLS, Commrex, Loopnet, BizBuySellI really appreciate any feedback or experiences people are willing to share. 

Best you can do is to interface with your PM's attorney directly to make sure you have all the information correct.

He knows I do real estate investing but unfortunately my work is currently primarily residential so I don't interface much with these types of organizations.

Their interface and features are dated, and the worst of all they lock you into a 1 year contract.

Google had (10 years ago) a pretty straight forward interface where I did my ads myself.

The loan is through the LLC so you'll need to interface with a commercial bank, another private lender, or hard money lender, or family.
