If you are in PA and the house you wish to rent out is in zip 95111 (San Jose, CA) I would recommend you find a property manager. Traveling across the country to monitor the condition of your home would be more expensive than hiring a property manager.
If the home you wish to rent out is in PA, your best options may be quite different from the San Francisco Bay Area. (your question is posted under home selling in zip 95111). Locally craigslist.org is a very good place to offer homes for rent. If you advertise your personal email and/or phone number you may get unwanted questions for months or even years.
If you promote your rental over the internet, also consider hotpads.com. Many real estate web sites pull information from there.
