Multi-family duplex | First time investor - Seeking Advices

[Maungmaung Y.]

Hello—

I'm a first-time investor here. We found a duplex property with tenants. Per our agent, rent is ~ $1500 for one unit and ~ $1700 for another. FYI, we don't feel like our agent is really investor-friendly. 

Can we request a financial summary/statement from the seller before making an offer? Are there any additional due diligence steps we should be doing before submitting an offer? 

We appreciate any advice and TIA.
