If they paid on time and didn't damage the unit don't waste your time or money pursuing this.

But it will ebb and flow, responsiveness is certainly important (both for tenants and damage to building).

It is the worst on the block.

No expense was spared as this home was only two blocks from the beach.

Also, does anyone have suggestions on how to minimize damage to the unit while they're in there?

We made sure our gutters were always cleared and have leaf blocks over them.When it still continued, my contractors noticed that my neighbors gutters were blocked and that there was a 4" by 2" by 2"  hole behind the gutter where the wood or brick had disintegrated. 

We just added a 2 bed 2 bath condo in Breckinridge. in the village two blocks to gondola.

Turns out that the HUGE tree in the backyard is dead and needs to come down before it does serious damage.

Hello,I had a tenant last winter and the heat in his unit was supplemented by the unit above him.It gets really cold down there in winter but he chose not to have free heat and sealed the vents tightly with an aluminum foil without  letting me know , I could have easily adjusted the thermostat to lower  per his needs if he had told me and supplemented my apartment above with any additional heat but he chose to seal without letting me know inspite of my warning later on and obviously it can have detrimental effect on the tubing inside the walls due to excess pressure build up.He also complained about high electricity Bill's (obviously he would incur high utility bills when he turns on his electric radiator without using the free heat he was getting) I ended up having an oversight from my end as I did not verify if sealing vent caused any damage . 

They left the unit in pretty rough shape: smoke damage in every room, ceiling fan broken, bedroom door broken in half, trash left behind, food rotting in fridge, and just general damage throughout.
