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.

It the tenant causes a fire and damages my house and neighboring houses then their renter's insurance will conver all the costs.My HOA has insurance.

Like deferred maintenance, (bad roof, worn out water heater/AC Unit, warped flooring, water damage) etc, unpaid utilities,  unpaid taxes, a second loan, unpaid HOA fees, a bad pool, bad reputation, sometimes squatters, sometimes they were drug houses, and so on.

If a company, it would be great to know of a reputable non-recourse lender.

They are very likely to respond, but keep in mind you can't get dollars from a turnip.My experience is wear and damage are higher with some S8 tenants and not at all with others, just like regular tenants.
