I self manage my properties with an LLC and have additional umbrella insurance.

And I carry an umbrella insurance policy.  

As of now i carry a 4 Million dollar umbrella policy for liability.

I also have umbrella in case things get taken to the next level.this is why trampolines are a landlord's nightmare, not good clean fun:

Do I need umbrella insurance if my liability limits on my properties are already 1 mil/property, 2 mil aggregate?

Plus he won’t need all the umbrellas that he did in your area.

Umbrella insurance, a quick explanation would be nice, from what I understand it's just a bigger coverage for your property.

Only thing was when I hit more than 4 I was required to remove the liability off each policy onto an umbrella policy but it's cheap. 216/year for 1 million.

My limit requirements are:Commercial General Liability Insurance$1,000,000 Each Occurrence Limit (Bodily Injury and property Damage) $2,000,000 General Aggregate per Project" $2,000,000 Products & Completed Operations Aggregate"$1,000,000 Personal and Advertising Injury Limit"Business or Commercial Automobile Liability Insurance$1,000,000 combined single limit per accidentWorkers' Compensation and Employers' Liability Insurance$100,000 Each Accident$100,000 Each Employee for Injury by Disease$500,000 Aggregate for Injury by DiseaseExcess or Umbrella Liability$1,000,000 occurrence/aggregateAm I asking too much?

I have all of my personal insurance (car, home, umbrella) policies with them also.
