2 Duplex deal evaluation

[Quinn Lamb]

Looking at two adjacent duplexes.  Listing for $580k, the four identical units are each 3 bed 1 bath renting for $1200 a unit.  Average rents in the neighborhood for comp houses are $600+ per bed.  Taxes are $9600.  Not sure on insurance or other expenses so if others have insights on that please share.  I'd be putting 20% down at 4.1% interest.  Does this seem like a good initial investment?  The properties are in decent shape in a great neighborhood, with minor cosmetics they'd look great.
