People who accept NOI<10% may never see AFFO>0, and therefore their Payback Time D is actually infinite. 

Assuming you are buying your properties right, you can then do a refi within 30 days and get all your money back, therefore giving yourself an infinite COC return because you have no cash in the deal!  

The reason I ask is that in the Bay Area, if you can get past the barrier to entry, you can get to an infinite ROI with BOTH cash flow and appreciation. 

We have in the past achieved infinite cash-on-cash return on deals using this strategy in our market and I believe we will again.This is usually called the BRRRR rental property strategy on this website.

However, i've found that a small directional sign to a house available for rent is infinitely more tolerable by nearby homeowners and any code enforcement, especially if it looks like it was hand written, simply because it DOESN'T say any of the commonly offensive Sales Pitches (We Buy Houses, Free Cell Phone, Medicaid Prescription Coverage, etc).  

For the Property Management course, you would get a textbook and access to take the quizzes for each chapter online (which you can review an infinite amount of times) and the final exam online. 

INFINITE!!!

Many get so focused on infinite ROI that they pass up 100% ROI "almost perfect brrrrs"

The ROI probability is infinite and there is no risk of losing money when you invest in yourself.

Just like the Universe the learning on here and knowledge is infinite and constantly growing.
