We're at 13 properties now, and property management has been huge for us as we're infinitely scalable now.I know I didn't answer your question haha, but still wanted to give my two cents from my experience.

However, those with good credit can have solar installed with 0 down, and where a zero down system pays for itself (taking in to account the hidden costs, risks, vacancy etc), they offer very high (infinite) ROI.  

.$30k down$50k appreciation$100 cash flowCOC Return = 4%YEAR 1 ROI = 166%# of BP investors pushing this strategy = 1 # of times I’ve heard Phx has no deals = infinite

More over its more about an "infinite game", it does not end in an year or two, decade or two.

Too many details to discuss here, but we use our paid up policy whole-life dividend paying life insurance policy as our own infinite banking system with a "death-benefit" attached to it.

@Steven Cruz If you get a chance, read "Becoming Your Own Banker: Unlock the Infinite Banking Concept" by R.

Your infinite wisdom, and how much experience you have in RE will not stop this from coming.

Infinite!

The stock market on the other hand provides an infinite pool to buy, no limits, completely passive   And your illiquid 198k equity gain is subject to the same inflation effects as my liquid 300k stock gain.

It's an infinite ROI.
