I don't have personal experience with this kind of land trust but since you're in CO I have a personal recommendation of a real estate attorney here in CO who has helped me with seller finance deals and is very responsive and has been great to work with in general - Jeromy Geraghty - https://www.geraghtylawoffice.com/

Bought the lot cash and found a bank who referred a builder to put down on paper to be responsible for a fee but understood that I would be a first time builder for my own personal build.

Take them out for lunch and see the kind of person they are.

I feel the Bowie/Upper Marlboro area offer great value for flipping and/or rentals because the costs are lower yet you can sell to the DC buyer.  

In short, the best Real Estate CRM to use is the one that fits your personality and habits in my opinion. 

One-year leases are very common in smaller spaces, as you're most often working with tenants in the trade industry that need a garage styled space for tools and equipment, some with a small 1-person styled office adjacent the shop.

I don't know anyone as a consultant personally, but an outstanding resource is PM Build with Marc Cunningham.
