Rental Income numbers

[Alexandre Medrano]

Estimating rental income is something that I am struggling with when analyzing deals. Any tips on estimating rental income? 

So far i have been using rentometer and craigslist for listings of similar properties for rent in the area. The issues that I'm having is that there is not enough examples in certain areas on craigslist and rentometer doesn't take into account for square footage of the units when comparing rent prices. Rental income is a BIG factor in analyzing deals so I wanted to ask the community for any tips and advice before moving on.
