Multifamily residential rental properties in Chicago - Expenses and Cash flow

[Elizabeth Joiner]

I have a few questions about investing in Multi-families in Chicago. What are the monthly expenses when owning a multi family in Chicago. I know you have to pay mortgage, taxes, home insurance, and utilites. Im looking for a more detailed listing of the costs. How do you determine cash flow for the property? How do you determine what to rent each unit for? I've heard that Multi families have a different determination for value than single family homes do. I have read that the value of a multi-unit is based on how much it rents for as a whole. Is this true?
