One SFR rental property LLC or no? Additional coverage?

[Bryan Christopher]

Greetings all, 

I've read a lot here and have heard conflicting opinions. Wanted to just gather some data and see where the current thoughts on the topic are landing...

I'm a California resident. I own a 3 bd SFR in the Las Vegas area. (Since 2016)

Currently I am not using an LLC for the property. I looked into it last year, but decided not to right now and I won't give the reasons... rather I'd like to hear any input.

I have homeowner's/hazard insurance on the property through my mortgage, but I do not have any additional landlord insurance or other coverages.  

We (wife and myself) do have an umbrella policy. 

Do I need to change anything in this scenario? (Add/change coverages, add LLC etc?)

With the market climate being how it is, and tenant quality becoming more challenging... I'd love to hear any input from those who have knowledge. 

Thanks in advance!
