Rentals in LLC Vs personal Umbrella

[Sayli Mulay]

I have 6 single family rentals, each has landlord policy (DP3 type) 500k liability coverage.

Last year I transferred (QCD) the properties from personal name to LLC so I added LLC as insured on those policies. The declaration page shows personal name and LLC listed.

Now I am trying to add them in Umbrella policy but the agent says - Rental properties would not be included under the personal umbrella because they are insured as LLC.

What is my best option ?

Do I need to change landlord policies to some sort of commercial policy ? 

TIA
