First time investor...Came across a good opportunity to invest in a 4plex (with established tenants but inspection can only be done during the DD period).I am feeling uneasy as I have always envisioned starting with a single-family home. cons?

But it made me a bit uneasy because I thought maybe I should be doing more to protect the property itself.

Renting each room to unrelated people might make your insurance provider more uneasy causing rates to rise.
