@Chris Oswald - You may want to check out this free BP course https://www.biggerpockets.com/courses/a-beginners-...Module 6 is about financing and there is a specific one on seller financing

We've just added a yellow-letters module to our REsimpli software to fulfill yellow-letters for great bang-for-your buck, I'll send you a PM offline as well. 

I use Insightly for CRM apart from proprietary CRM software modules as part of two seperate ERP systems in our other lines of businesses (brokerage and property management), but it is a lot of work to set up all processes (pipelines and activity sets for each activity).

I then started exploring Modular housing (NOT a mobile or Manufactured ones) and found that they are built more stronger and efficient,   mortgage lenders do not differentiate it,  public records and MLS lists them as regular houses,  personally visited their factories,  seen met home owners who has been living in modular homes past 10+ years,  almost all module companies offer a turnkey service that takes care of everything from preparing the site to permits to setting up the house.   

The one that I bought is basically a “SEO 101” course with different video modules on how to do on-page and off-page SEO.

They have eduational modules that teach you how to use Craig's List to drive traffic to your website for free. 

You get the next 11 modules one at a time!

The class was all web-based, consisted of 10 modules including a video (the coach speaking and discussing) and a matching power point presentation.

4) What modules? 

They offered an advanced training for $28K, several training modules, strategies for shifting markets, financing for up to 1 million dollars per deal.
