Just off the top of my head, I wouldn't feel super comfortable with non-US properties because properties in the US are held to HUD code (at a minimum).

Here is a recommendation I have for you as you begin to figure out what area you want to invest in.This website is a great reference point for figuring out what each area is like. https://www.areavibes.com/It gives you a total LIVABILITY score for each street and zip code & discusses crime rate, schoolsUse this rating and classification system I have created over time to get an idea of the "Class" for the area - A class B class & so onHere is my rating & classification for each livability score.80 and above A+78/79 A76/77 A-74/75 B+72/73 B70/71 B-68/69 C+66/67 C64/65 C-60/63 D59 and below FBest of luck and let me know if I can help answer any questions! 

Very good point.In the case of Arizona, I have been unable to locate any state law / code that suggests Arizona may have additional regulations. 

Your first challenge is - you shouldn't buy based upon zip code!

So, create status codes for both of these and a few in-between codes to help you work smarter, not harder.

Based on the rents, I would guess the $1350 house is in a C+ or maybe B- area, and the $950 is in a C- area.What neighborhoods or zip codes are these in?

Guys have heard that ad nauseum and its now a code word for "Do it cheap".

That entire 78741 zip code is good and has been in high demand historically due to its location. 

Of course you always ensure good living conditions for your tenants which is a matter of honor! 

Maybe also include City and Zip Code as columns in the sheet.
