Things to look at on Quadplex showing and put contingency

[Jaekwan Lee]

Hi folks,

I am new on buying a property and trying to househack on fourplex property that is 40 years old(1980's). The showing is scheduled and as long as no big concern arises, I am going to make an offer. So I have a few questions. 

- What are the things to look for while we are in showing the property other than kitchen & bath room update?
- What are the typical/favorite contingencies do you add for four-plex property?
- Any useful questions to buyer/seller agents?

Here are some details about the property.
Price: 480k
Age: 1986
Rent: 1100 ~ 1200/unit
CoC: 3%
CAP: 7%

I am a first time buyer and house hacker so any insight are appreciated.
