When you start you need to look at every expense (housing, transportation & taxes are the big ones) as dollars that could be invested into real estate, earning you more dollars. 

Any sort of bills - food, living expenses, medical, insurance, transportation etc will eat that up instantly.

You need to buy some kitchen equipment, one or two of the good basic cookbooks like "The Joy of Cooking" or Bittman's "How to Cook Everything," and build a sustainable repertoire of 10-15 cheap, healthy dinners with a few variations each that you can put together easily and quickly.Better for your pocket, better for your mental health because it will help ground you, better for your love life because smart, capable people appreciate personal cooking skills in others.The top three expenses of the American household, as @Scott Trench's book taught me, are housing, transportation, and food.

@Matthew Ruderman, a couple items I look at which are transportation and job growth as factors to steady to strong rentals.
