House Hacking a duplex.

[Morgan Martinez]

Hey BP, I am moving into my second investment property which is a duplex, and I was wondering how people would handle the tenant on the other side. Would you tell them you are the new owner, or just give them a number to reach me and tell them I am just renting that side I live in? I also would like to know if I added security system to the whole duplex, how would you go about it? Thank you in advance!
