I tried to invest in real estate this year [it was a rental property, not my primary home] and I incurred some expenses in the process. I ended up not making the investment after all. Can I take tax right off on the expenses made [gas, food, etc]. If yes what form do I need to use for that?

I don’t think so; In order to properly determine the correct treatment income and expenses, it is first necessary to classify the type of investment (rental) activity occurring.
