Determining rent rolls from MLS?

[Paul Spangler]

I've been looking for a multifamily in the Portland, Oregon area and browsing the listings on realtor.com, and some of them have an "actual gross income" value in the info. Should I take that as the annual rent roll when determining if I want to look further into the property? I'm trying to buy using an FHA loan and they need the PITI to be less than 85% of the market rent for the property and I'm having trouble figuring out if a property will meet that at first glance.
