@Michael Blackwell great information, yeah the challenge with house hacking multiple bedrooms is finding our own privacy...but I understand that the basis of a house hacking strategy is temporary inconvenience for a long term benefit! 

I've been doing a lot of research on setting up an LLC structure to hold the properties for personal asset and privacy protection. 

A double closing has more anonymity and privacy, but you will pay for it with closing costs.

Last year the ground level patios and privacy walls were $19k per unit, made the roofs seem like a deal. 

For a str, definitely a pool with privacy is always preferred.

LLC does not provide much protection, mainly for privacy.

The tenants will want privacy in their space and not worry about the other tenants stealing.6.

Also almost 99% of the notes out there say the borrower has to be current for the past 12 or some 24 months- this one they are many months behind and late.Other note:No listing agent is going to give interested parties copies of a seller's note and the riders because of privacy issues.

(3) How big of a difference for privacy for property of 2 acre size vs 10 acre？

Consult your legal counsel.Another item to Google is "FinCEN"If you think privacy today is getting reduced, wait till the govt starts using their own digital currency and know every transaction you make.
