Private lenders would be your best bet...but your play on the rental would be a cash-out re-fi more than likely...I really don't like the concept of assigning debt to your holdings just to buy more properties...your one rental paid off entirely will cash flow more than the next 5 you acquire with debt. 

@Jessica Roland BRRRR isn't exactly a sustainable concept...and it appears you've found out.

@anthony LadsonA lot of the same concepts some different terminology.

You can sell now on potential but proof of concept always pays better than potential.

Each bank works differently but the concept is the same. 

I live in Omaha and am frustrated with zoning here, but I really like the concept of conversions/ADU's. 

While his business model wasn't completely interesting to me in a practical sense, I agreed with some of his concepts.

@Daniel M Gibson sticking to fundamentals and your "gut" is always the best course.Unlike 99% of the investors on this site, my take is that investing for cash flow is a bad idea...it creates a jaundiced view of how things work...meaning that investing is about controlling assets as wisely as possible...not immediate cash flow.I use seller carried loans routinely because I'm in for the long haul (and I don't need rental income to survive)...as long as the purchase price makes sense, I could care less about income...the concept is debt paydown and future equity.
