You are the second to suggest PA so I think I will begin looking into it.

@Eric Hathway Great suggestion by Account Closed.

that's rare, but it suggests a lot of things about your building...like the condition, assessed valuation, upside potential, etc...I've personally never seen a 6-unit in a good area with taxes that low...Overall, I think your returns look really low, so I would say this is a relative investment...if it's in great condition in a great area, maybe it makes sense...hard to tell much more without the full property information...
