Insurance about water damage in DFW area

[Jaimie Chen]

Hi,

I am shopping my rental property insurance and agent gave me a quote has this endorsement really confuses me: "Amendatory Endorsement water Damage" for $1000

The property is in DFW area and is covered @200k for Coverage A. Dwelling, Dwelling Extended coverage, and Dwelling Additional Extended Coverage. Shouldn't those coverage already take care water damage claim?

For 1% deductible, is $1000 for water damage sounds enough for you?

The liability only 50K, but we have umbrella insurance. Will that work?
I am new to insurances. Like to hear some inputs.

Thanks.
