However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

@Michael Plaks Kudos to you for creating this post and countless others that provide infinite value to the real estate investor community!

It will only cash flow about $150/door/month, but I tell you this to point out that cash-on-cash returns are nice to analyze, but I am getting to the point that something that cant be an infinite cash-on-cash return at some point in the near future just doesnt sound that appealing.  

You have an infinite ROI bc the property was free, but you are generating a 4% annual return ($100x12) on your 30k equity position. b.

If I had infinite capital it would still likely take me another 6-7 years to buy 150 units.

its mostly focused on retail, but the inputs are infinitely adjustable for whatever asset you are going after.   

However not finishing the rehab or in those areas the top rehab contractors wont even work there.. that's another thing most people don't understand your not going to get top shelf contracting or rehabbing in assets that don't warrant it or have the funds to do a full rehab.I fund a few turnkeys in Indy the average rehab to do a proper rehab is 25 35k per house.. so stands to reason these 5 to 10k rehabs we seen talked about or even 15k.. u can only patch and fluff and paint over etc.. those houses if you think you just rehabbed them that wont be the case you will have continuing cap ex that will kill the investments.

If you've enjoyed a lot of appreciation in the value of your primary home, you may want to start a timer to sell before losing the "lived in the house for 2 of the last 5 years" capital gains exemption (limited; not infinite, but big).  

That to me is the simplest deal structure and the least "risk to you" as you aren't waiting for the final home to complete to be paid, as I understand it most construction loans close on the "dirt" up front....although like everything in real estate its infinitely negotiable and changeable.
