Buying A Duplex For Sale By Owner (Inspection and Due Diligence)

[Asher Knudson]

I'm looking to purchase my first duplex property for sale by owner and I'm a little nervous about navigating the inspection process. The house was built in 1920 in Minnesota. 

I want to make sure I know everything is up to code and I have a thorough check for asbestos, lead paint, etc.

Does anyone have a list they like to check off for inspecting homes of this type?

What kind of due diligence steps would you take to make sure you can limit surprises later on?

Thanks in advance!
