Frequency and guarding against water Damage

[Adam Jaggers]

Hey BP,

Just wanted to get thoughts from the community. I've been investing for a couple years now and have about 15 doors (various types).

I've been hit with pretty bad water damage basically twice a year from various sources. Im averaging basically $1k a year per door in water damage. 

Does this seem typical ?  What things are you property managers doing to prevent this kind of thing?

thanks in advance
