We do this primarily by building extensive networks to helps us get the best deals, honing in our rehab processes, buying things wholesale, doing the same work on every property every time to maximize efficiency.

Err, well as many units as you can (4 is ideal) same loan and the cash flow and efficiencies really add up.  

Basically GCs don't systemize their businesses, partially because if a system is too efficient then they eliminate themselves as a middle man in that system.

More crisply, what is a ROFR is worth to a nextdoor neighbor who'd love to have control of what's next to his fancy spread and who could build a $3,000,000+ house on the land, very efficiently,  with his eyes closed (and not have to drive to the job site)?

The vision is for an easy and efficient networking meetup that professionals can squeeze in over lunch.

@Kristen Graham the opportunity to increase efficiencies of an building should always be part of our evaluation.

I want to make other peoples money work for me as best I can, but I want to expand out and build out this passive income stream in a extremely time efficient manner so that I can limit the time I'd spend in a Duplex and get closer to my dream home and car.

Our profits are made by doing things more efficiently than the investor can do themselves.   

You're able to realize efficiencies of scale, reduce your risk, and scale faster.I'm personally not a fan of paying off your properties completely, because your Return on Equity (ROE) is usually pretty bad.

The house has baseboard electric heat throughout but it seems to not be efficient and runs up the electric bill dramatically.
