Check out INREIA as well as the Alpine meetup.  

With single-family homes there are constant repairs from new roof's to HVAC problems, to leaky basements, to peeling paint, to bug infestation, landscape issues, the list goes on and on.

You're not accounting for Landscaping that I see.

The broker you are supervised by, as well as the brokerage firm holding your license, would be similarly exposed, which is why many brokers will not hold the license of agents engaged in wholesaling.It is important to know and understand the legal landscape before undertaking any endeavor.

Looking for an affordable contractor and landscaper in PG County MD.

Condo associations generally take care of common areas like landscaping, pool areas, and routine maintenance/repairs of the exterior of the building.

The landscaping needed work too, I removed scraggly and overgrown bushes/trees, put in two block walls, a patio privacy fence, lots of work on the grass.
