I agree 70% rule is kind of simplification, but finally i see the main difference between flipping and building is that while flipping goes you earn money on buying with cheapest repairing, but while new development/deep rehab goes you earn money getting adding value for highest market price comparing of rounded properties in this location. 

Not sure how property management would fall.Separately, there may be some local development money available for real estate (more often renovation than acquisition, but every bit helps!).

Hopefully @Brandon Turner will answer, if not, shoot him an email.I was thinking about developing one, since I haven't found a good one yet.

Crowd funding is also a way to find out what the crowd funding firms are getting from developers. 

I do know that developers are very focused on the I-10/1604 area right now, which is just south of Leon Valley.Building Classes...very short descriptions:A: top-quality building, getting the highest rents, very well-maintained, best locationsB: One-step below "A".

Developing a trusted team is probably the most important step.

@Aaron McGinnis Exactly what I thought it will be, another useless tool that app developers think works. they are always a dreamer, hoping for the next best thing.

You need to develop a plan on how to generate 90k per year through real estate.  

Initially I wanted to wholesale to build capital to fix and flip and then develop.

I tend to lean that way as well and don't mind jumping into the trenches and getting my hands dirty as I'm also a general & manufactured home contractor, manufactured home dealer and developer, real estate broker, investor and property manager.
