There are services online that are free or for a fee.Some title companies can provide you with access to their system to pull up data.

Zillow uses a simplistic data feed from Rent Range. 

Over decades of data multifamily has averaged 10% vacancy, 50% op ex, 1 to 2% rent increases annually.

Also factor distance to schools, nice shopping centers, crime, etc. and other important data.7.

I've been able to manipulate the data in some way to get it to positively cash flow (rental incomes higher & lower purchase price), but I guess the question is how do I know what is too aggressive when it comes to adjusting prices during the analysis phase of a rental property?

(I believe the data says 4/5 of DO NOT exercise their option).Business owner will place himself in a position where he's given up $150,000 in equity and received $40,000 in cash for it. 

I'm having a fairly tough time finding useful data on these items.

@Marilyn Mike For comparables, Trulia or Zillow are OK, but the gold standard is MLS data.

And it also helps to have someone who understands your situation and startegy to validate your deal before you make an offer.I set up MLS Portals for my clients so they can browse inventory and have real time data, which basically gives them MLS access for their target area.
