The U.S. market is certainly a different market from Australia but can be very lucrative even for us as foreign investors. 

Even small, common mistakes like renting below market, picking the wrong tenants, unwilling/unable to enforce lease terms, slow turnovers, or unscrupulous contractors can cost more than a good PM will charge, and that's before you account for your time and the stress.If you have the personality, I recommend self-management for anyone who lives within 1-2 hours of their investments.
