New Duplex in Ann Arbor should I build on or just rehab?

[Kit Klekamp]

Hello,

I was able to purchase a duplex in Ann Arbor that is completely value add.  It is almost a double lot down town and I was wondering, should I just fix it up or should I pay to get another building built next to it.  The duplex is a 2/1 and a bit small, 1440, so each unit is only 720.  Any suggestions would be greatly appreciated.

Thanks.
