@Carlos Teves a landlord policy is usually less expensive than a homeowner's policy, however I don't know how the pool will affect that, because if god forbid someone in your own family had an injury or drowned you wouldn't sue yourself, where a tenant might.

Throughout our rental period we kept regular communication with the owners noting injuries from numerous nail pops, dislodged staples, ripped carpet seams and fraying carpet.  

Asking the borrower to cover those extra costs is adding insult to injury. 

Other then that there is the ambulance-chaser lawsuits, they came walking up to a property, slipped, fell now have some diagnoses by Dr Quack and sue for personal injury and want to attach all your income because your the "Big Bad Rich Landlord". 

I will PM you the companies you should start with.The General Liability portion of a Landlord/Rental Dwelling policy will respond to Property damage and Bodily Injury claims.   

Personal Liability: For claims due to Bodily Injury or Property Damage that you becomeLiable for and which is covered under the policy.

Most likely the state where the property is located is where lawsuits would be brought if they are something for personal injury like a trip and fall or something of that nature because the “cause of action” arose in that state.

If the city looked into it then and found the deck not to be permitted and the cause of injury or worse, you're in deep trouble my friend.

Part of being a PT is being very hands-on while working with patients as they recover from various injuries and surgeries.

It's not like the lawsuit would involve personal injuries so your exposure is not significant.
