When a Property Manager is hired, they perform a variety of different services on behalf of the Owner. In general, the Property Manager does not have a financial interest in the home as they are not part Owner. However, they do take on the risk and liability as if they were a Homeowner. Assuming the Property Manager does carry E&O Insurance and General Liability insurance, this only offers protection from claims that are a result of the services provided by the Property Manager. It does not offer any protection against matters concerning the home itself.
So in essence, the Property Manager assumes all the liabilities of a Homeowner but their insurance policies do not offer the same type of protection as a Landlord insurance policy. This leaves them vulnerable to claims and lawsuits arising from the property itself. Some examples of where the Property Manager would not be covered by their insurance policy include someone injuring themselves at the property, burglary, fire, water leaks, etc.
