We did the research about LLC vs Umbrella Policy and ultimately decided on a $2mill umbrella rather than the LLC for this particular property.

I declined, and instead got a personal umbrella policy in addition to the standard policy.  

It is also a good idea to have an umbrella.- Some pools are high maintenance (debris from trees, plants, difficult to balance chemicals, etc). and require a pool service.

And make sure to account for the following in your operating expenses to get to the real cash flow:1) Mortgage2) Mortgage insurance (PMI or MIP) or FHA Risk base3) Property Taxes4) City Taxes5) HOA (Home Owner’s Association) Dues and Fees and Assessments6) Insurance   a) Property Hazard Insurance   b) Flood Insurance   c) Earthquake Insurance   d) Umbrella Insurance7) Vacancy Rate (usually 8% - the equivalent to one month a year, or 5-6% if multifamily and/or if experienced, if not use 8%)8) Utilities (you’ll have these if your tenant is not covering them and/or during vacancy)   a) Water § Sewer § Garbage   b) Electricity   c) Natural Gas   d) Propane9) General Maintenance (usually 5%)   a) Upkeep § Landscaping   b) Snow removal   c) Repairs   d) New Appliances10) Capital Expenditures (usually 5%, higher is the property is old and obsolete, less if fully rehabbed and all mechanicals and roof are new)11) Property Management (8%, even if you self manage, your time still has value and there might be a time when you'll want to be completely hands off or you'll not be able to do it, vacation, retirement, etc.), including...  

Some, like me, add umbrella liability that also protects your property from YOU - Third line of defense is having a mortgage. 

You may want to consider an umbrella policy with a lot of coverage.

My other thought is to invest without an LLC if it's going to be complex until i receive my green card and have an umbrella policy to cover myself.

To manage the personal risk, I am thinking of purchasing an excess (umbrella) policy of $2M that covers me and my personal assets (If I had LLC, I didnot have to worry about this)2.

On my first property I went with the umbrella insurance since at the time it was hard to get a loan and I would not get a loan buying as an LLC.

Example, could I hold all assets in one LLC (and add an umbrella policy for extended protection), and then operate from another?
