Until 2000 they were independent of any affiliations with companies or people selling products, with the exception that they might charge a small fee to “speakers”.At or around 2000 the National Real Estate Investors Association (NREIA) was formed as an “umbrella” organization in which local REIAs would be members.  

They also have my auto insurance, and I took out an umbrella policy with them as well.

Maybe think of the fact that if you put all those properties in an LLC, you'll have a heck of a time getting an umbrella policy so you'll have exposure.

Insurance would cover it, I would pay the deductible, and no assets would be lost.If you are in an area like San Diego where people are more likely to sue, a judge is more likely to find you guilty, and the payout is expected to be higher, you may consider an umbrella insurance policy.

I had analysis paralysis yes it’s a real thing, even if it’s just an umbrella term for a multitude of factors.

Make sure you have great disability insurance (Guardian is top notch), a great umbrella insurance policy, and an LLC with a thick corporate veil (and great property insurance). 

In adddition to requireing my tenants to have a renters' policy, I have umbrella insurance that provides additional liability protection (above and beyond what your homeowners provides for your rental).

Right now, for the liability coverage, we have an umbrella insurance in place. 

Maximum liability coverage and a good umbrella policy is going to take care of 99.9% of your needs and exposure.

Search for LLC vs umbrella insurance policy to get an idea of how controversial the topic is. :)Hope that helps!
