Outside of the law what are the necessities to have tenants in a duplex pay their own utilities.

My true goal is to earn enough cash flow to 1) cover my necessities and general living expenses and 2) replace my W2 (I have the approximate numbers for these goals based on my own personal ambitions.)Based on your comment, it sounds like I should strive to own high quality real estate in medium-high barrier to entry (read desirable, appreciating, etc.) neighborhoods.

Need is the mother of necessity and we are all wishing you the best of luck!

It sounds like you moved not out of desire but out of necessity.

The property we have found is brand-new, never lived in, has parking (which is a necessity in the area and most properties do not have), but it isn't a bargain.
