We've never collected rent electronically, but we'd like to start.  

. $40/door, landscaping - am I missing anything?)

Landscaping would help.

After the land, site prep, set up, and delivery you still have to build porches, driveways, landscaping maybe, etc.  

I should have added I guess that the rehab costs (roof, deck, floors (refinishing), kitchen (cabinets/counter/floor), bathroom (tile), deck, AC unit, water heater, some minor modifications to the interior space, complete painting on interior and exterior, new front and back doors, some landscaping) would cost about $40,000, which would put me all in around $90,000.  

The long term goal is to build a network inside a large buy/hold portfolio to be able to set up other enterprises and P.E.O (billing, land scaping, rehab etc).

A customer called my landscaping company looking for a quote on some landscaping rehab.  

@Tushar Shah @Ian Ippolito's site is an excellent resource for navigating the real estate crowdfunding landscape; I learned a great deal there myself as someone new to real estate (with some experience in crowdfunded startup and P2P loans).

The tenant essentially pulls their own report and shares it electronically  (I would not recommend allowing the tenant to bring their own report as it could have been easily altered).  

But I can tell you that if you are a first-time landlord the major benefit to townhomes is that the HOA is likely responsible for major structural issues, yard/landscaping/driveways, all significant plumbing, etc.
