Do not know what State you are in, but the best thing you could do is join your local Apartment Asscociation. There you will have sources pertaining just to your State and locality. They have coures on everything that relates to your being a landlord, State laws, Building and Health Codes, Fair Housing, Etc. You will also have people that can be a mentor to you for those little problems that grow into big ones. Most books are written in general terms and do not really relate to the small day to day problems that a landlord has.
