Finding and/or aggregating Price-to-Rent Info

[Mark Hamrock]

My partner and I are looking for out of State markets to purchase buy/holds and we are currently in the process of gathering macro metrics. Does anybody have any advice for a good way of aggregating price-to-rent data? I don't really trust zillow or trulia for accurate data... I've been going on realtor.com, CL, and looking at prices and rents for comparable props but there has to be a more efficient way or a pre-existing resource that has this data combined, preferably on a map. Thanks in advance!
