Multi-family Investing Due Diligence

[Grant T.]

Hey everyone, I am seeking advice from anyone who knows about Multi-family investing. Just hypothetically speaking, say you found a place you think is a great investment, all of the numbers make sense to you, and there are currently tenants renting out 9/10 of the units. Aside from the finance side, what is some other due diligence you would do before going forward? Any tips, advice, and stories would be greatly appreciated.
