Trouble Getting Good Estimated Numbers for Analyzing Properties

[David Franco]

Hello, I am new to real estate investing and I keep running into trouble when it comes to estimating the expenses of the potential rental properties I'm look at. I've been looking for a good estimate of the expenses to make the deals cash flow theoretically, but I still don't understand why any of the properties aren't yielding cashflow. Am I missing something? Or maybe something I don't know? I would really appreciate some help.
