How is my analysis logic?

[Thomas Daly]

I have spent the past 12 months reading the forums, particularly on how to sharpen up my skills on crunching the numbers on potential deals, to mitigate the risk of making a poor investment decision. I made a resolution that 2020 is the year that I will make my first real estate purchase, and I plan on going through with it! My plan is to buy a property, live in it as my primary residence, and to eventually move out of the property but keep as an investment. As such I did my analysis on the assumption for this future scenario, where I have moved out and all units are being rented.

I have found that investors have many different ways of crunching the numbers. What I have done is taken the different aspects of several calculators I have seen on this website and tailored it to my own criteria. My long term goal is not to manage a rental property empire, but to own a few properties to diversify my investment portfolio away from only stocks, bonds, etc.

Are there any glaring mistakes in the below? Something that is a risky assumption? Note the the property mentioned below is completely made up and not real, the purpose of the below is to validate assumptions and formulas on cost.
