I'm looking for the lowest entry-point level to generate cash flow and learn the real estate business.

Have to have the right realtor and the right construction crews . 

I planned to develop another home in the back half but a contractor inquired about renting the lot for their construction trailer so I’m pausing my development. 

@Nathan Gesner I agree, because my rental is a business and I shouldn't waver away from the screening process even if its just a trusted contractor, but funding is what we need and I heard the SBA is a good source but is slow, thanks for responding.

Don't overpush your real estate business early to investors because you are there to learn first.

Example: If he is supervising construction crews - yes.

However its often easier to entrust those who do this as a business to buy the assets and provide you with a solid return. 

get more micro. we define a zip code as a market. there are about 7 zip codes in the city of columbus that we work in as well as about 15 in Miami. we look at the average housing unit delivered and try to develop under the median and average home or condo where there is a lot of absorption. that is mostly through smaller Floorplan design, smart floorplan design, etc. new construction and development you also have much more control over the overall development just my 2 cents. if you are just buying existing it's going to have some issues 

What is your experience in anything related to real estate, construction, development, etc.? 

This is a great way to learn about "construction", what it takes to make a property marketable (e.g., trades, remodeling, permits, taxes, settlement process, etc.).
