How do you believe they damaged this door seal?

On the disclosure form, the seller had indicated “no” to any known damages.

Maybe they would/could take it upon themselves to pay for the repairs to the roof to salvage your unit and prevent further damage then they would go after the HOA to recoup costs.

Quote from @Alex Tang: One of my rentals was heavily damaged by a fire after Thanksgiving. 

I expect that I may have excessive damage on this home as well. 

The guests have a credit card on file and your policy should allow you to charge for damages or excessive cleaning.

Aircover is a mild form of property damage insurance where they MAY cover a guest's damage at their discretion, and you will have to fight for it. 

You are allowed to charge for ALL damages beyond ordinary wear-and-tear.

They offer a $10K repair fund to fix damages in addition to SD plus warranty for appliance repair etc.I have no say in whom they choose to move in, whether there are animals, limit on # of occupants etc. they reserve right to inspect property so i have no idea if they can tell me to remodel, paint etc.does this make sense i have a vacancy coming up in October (bad rental timing).

Houfy now has a damage protection plan that costs the guests $5 a night and does light identity screening through SuperHog.
