Oh, no, better one, bring my hair back! 

Hi Steve, I am glad it is helpful and thanks for taking the time to provide me the feedback.To your question: on the top 10 bar chart, there is a green arrow on the bottom right after the "10th bar".

You can read all you want, but you just don't know until you are in the middle of the process (wanting to cry, pull your hair out, sweating profusely because it is phoenix in the summertime and 116 degrees and what were you thinking flipping a house?!)

There is about a dozen points that show an inverse relationship and a dozen other points that show the opposite in that chart.   

Almost every gray hair I get I attribute to the parks that I manage..

I like @Paul’s abacus and wall chart more and more. 

(a health, environmental, public nuisance and waste, liability among others issues,)Even if the lease doesn't directly disallow a business from R-1 there will be in contract something addressing tenant's responsibility to protect the landlord property , not creating waste, commit public nuisance, or damage.I would have no problem to a good, responsible tenant for use the residence address for ex. handyman or plumber since he does not physically conduct his business from the home, and all his tools might be in his truck or rented storage, but I still would make sure that I am not being liable for loss, damage to his tools...and request he has a rental insurance, compliance with city regulations.Conducting online seminars is not the same as doing a hair extension, or running car repairs shop from R-1.  

All this for a ROI of 1.6% and not the 3.75% as shown in your chart since $876 / $53,000 = 1.6%The only way you can make a profit with this property is if it appreciates, significantly.

From reading these comments, it looks like I'm not alone.I guess it's like how I don't do my hair and make-up for my husband during quarantine, taking people for granted is human nature!

The appreciation markets historically have achieved outstanding cash flow over long hold periods.Then there is the appreciation reflected in @amir M. chart.
