Liability protection for main company

[Calvin Thomas]

I have my portfolio setup in a fairly complex, but prudent way. I have a main LLC, which is a c-Corp. It controls the financial reserves, expenses and payroll. Each property is in it's own LLC owned by the main LLC. Each LLC also have it's own property/liability insurance. The main doesn't have any insurance, however, I was thinking of adding a 4 million umbrella just in case. I just worry about claims or issues that can happen in the future its mold, structure issues, lead, etc. Properties are in NY, NJ and CT. Am I being a bit worrisome for no reason? I worry because my main company holds significant stocks and securities, as well as being the sole owner of all my other properties.
