Help me understand the benefit of a secondary rental agreement`

[Daniel Murphy]

Help me understand Rental Agreements, outside of Airbnb.

According to the Airbnb TOS, when a guest books with us, they are entering into an agreement directly with us as the host (the Airbnb TOS).

Does getting a secondary rental agreement through a management software really add any extra security or liability release? 

I understand the benefit of having guests' contact info for myself, but in 2 years we have not had much success yet with recurring guests coming back to book directly.
