Buying my first Duplex, is it a good idea?

[Shane Welch]

Hello,

I am starting my first adventure with a 1975 Duplex.  One story, mirrored 2 Bed 1 Bath Units.
This property is in Norfolk, Virginia and is being listed for $183,500.  Each side is currently being rented for $750.

What amount should my offer be for? ( I wanted to offer $160k)
Would renovations be a good ROI for both increasing home value and to raise rent?

Any general advice for me before going forward?
