Some PM companies advertise their rental houses online, some in the newspaper, some in both media.
Your profile, Blitz, says you are home owner. so you confused the Trulians as to why you are asking this question. Either you clicked the wrong box, or ?
If you're looking for rental listings, check each mgmt. company's web site, or google "Sacramento rentals". If you're trying to establish the rent value of a home you own, do the same google search, and call the management companies and ask them for their advice. They'll want your business, so will be happy to help.
When you say "can you get listings from property management companies"... what are you trying to accomplish...?
Are you trying to compare rents in an area where you own a property, or are you looking to rent a property...or have someone manage your property...
I'm not sure exactly what information you need...
