Forecasting Expenses for Buy and Hold Deal

[James Danchus]

BP,

So I'm trying to break down these deals in the "Rental Property" calculator and it's asking me for things that I can't really answer. For instance, how do you know what the electric bill is going to look like? Insurance? How do you find the vacancy rate for the area? What are you suppose to put aside for cap ex? 

It's a lot of stuff I am not sure you can find until are at the table, talking to the seller. Any advice?
