How do you count the square footage for a Mother in Law suite. 

If you fail to follow the rules, you may open your personal assets to a lawsuit.

You're spending way too much energy figuring out how to protect something you don't even have against enemies you haven't even made.I've been on BiggerPockets since 2010 and haven't found anyone that lost their equity to a lawsuit.

Anyway, he used to say, "We'll invite everyone to the law suit party and find out who's got the money".

In which case every  llc you own would be lost to the lawsuit. 

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Any lawsuits should be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced, some debate as to SMLLC).

Lawsuits sound great in theory, but in practice they are expensive, time consuming, stressful, and rarely end well for anyone. 

Lenders have checklists they send to the HOA and master insurance policy to check for pending lawsuits, pending assessments, the reserves of the HOA budget, and the financial footings of the HOA.

Additionally at that price point in VA ,I would also recommend finding a property that has either an additional dwelling unit, casita, or mother in law suite that you could convert into a Short Term Rental like an Airbnb or a VRBO. 

If you fail to follow the rules, you may open your personal assets to a lawsuit.
