I have found that CONSUMER ACTION is an excellent resource for objective advice on all things credit related. You'll find free and sincere advice on everything from settling collection accounts to rebuilding credit to building credit from scratch on their website http://www.consumer-action.org/.
Beware of anyone offering to "repair" your credit! The Federal Trade Commission issued a stern warning last year that such offers are scams. Find more from the FTC HERE. http://www.ftc.gov/bcp/edu/microsites/moneymatters/dealing-wâ€¦
That will really depend on the landlord and/or property manager. I don't rely on just the credit score, therefore, something in the low 600's may be acceptable. Many good people have lower scores now if they had a short sale or foreclosure.
Good Luck in your search for a home to rent.
