The point of making money at the end is to have consumption of things you want, now that might be food, gas money, your internet bill, and yes your housing. 

In addition, they always exclude energy and food, which for most families is the LARGE expenditures each month.

Your fav food.

Each room I charged the same rent rate for and rent covered all utilities.Kitchen: Fridge space was a little bit of a challenge, but it was more-so cleaning it out... we pooled food (split the bill) but all of us were the same eating style and one of our roommates directly benefited from us cooking his meals.

I have a commercial acre that a major fast food franchise wants to buy, but wants to wait 12 months for a hotel and a hospital that is coming with a mile.

I liked the tops for warming towels, or keeping food warm in the kitchen.

My biggest cost would likely be medical insurance, food being the second, quarterly tax payments, normal bills for the home.Is anyone here living off their rental properties?

Usually free food and free drinks.

What, if any, expenses are allowed as tax deductions ie: food, travel expenses, rental car, flights?

On the other hand I would be foolish to only buy my food at a gas station as the only method.
