Like @Nathan G. said, is your bank going to discount your mortgage payment if you did the same? 

LOL - big G at its finest.

I suggest posting signs as @Nathan G. recommended and placing "No Swimming" rules in your online house rules on your Airbnb and VRBO listings.I would even include the "No Swimming" sign in your pictures too.Doing this MAY reduce your risk to an acceptable level.
