My recommendation would also be to get the highest liability coverage available on your landlord policy and then to follow that up with an appropriately sized umbrella policy considering all your assets, future wages and growth of both.

A standard homeowner’s policy probably does not provide coverage for an investment property, a property that is vacant or a property that is under construction or being renovated.

Our goal is to secure properties (amount tbd) to help supplement our retirement.

Syed,I would advise that you require Workers Compensation coverage as well as General Liability coverage. 

It acts as a homeowner's policy and an STR policy, and their coverage areas seems broader than other products. 

Interest income funds using dividends to supplement her income.....

Property Coverage (internal & external)?

One thing about the analysis as actuals, is that the debt coverage is only 1.14.

I am looking to start investing in real estate to supplement my income, pay off my student loans, and eventually develop a substantial "passive" income stream.

@Kristen Ray - get a good general liability policy on top of any dwelling coverage you get for properties your LLC owns.
