Yes. Property managers must understand and comply with provisions of legislation, such as the Americans with Disabilities Act and the Federal Fair Housing Amendment Act, as well as local fair housing laws. They must ensure that their renting and advertising practices are not discriminatory and that the property itself complies with all of the local, State, and Federal regulations and building codes. Property managers also have the resources and knowledge to help evict problem tenants.
In short, property managers know your rights and obligations as a landlord, which could limit your liability exposure.
