Your bigger issue as as I touched on above is maintaining your corporate veil, otherwise this whole exercise of using a LLC is moot and you'll have a big surprise if you are ever sued.As far as choosing a name, certainly using the street address is very common. 

Anecdotally, this has been very surprising to some people who previously associated Natick with the mall & not much else. 

(Which is surprising in the Live Free or Die state) While I have no doubt that what you are saying about your personal situation is true, in NH, the situation is quite different.   

It often surprises me to find out how many people have viewed my profile.

I’m surprised no one has mentioned house hacking your current place to generate more cash to invest.

You might be surprised and ask them if they would charge an extra fee to do that property management.Good luck to you!
