You should contact the property manager directly. How did you find the home? Was it listed for rent or is there a sign out front? There should be contact info either in the ad or on the sign.
Be aware there are a lot of scams on rentals being posted on Craigslists and other sites and turns out the property is not really for rent. If it seems too good to be true, it probably is a scam. If there is no property manager or if the landlord won't meet you at the property or doesn't have keys chances are it is a scam.
post the link if you found it on Trulia
