Am I paying to much for a Lower West Side Chicago Multi-Unit?

[Nicholas Pascullo]

Hi BP!

I just went under contract for a gut rehab 4-unit in Pilsen, Chicago.  It may not technically be Pilsen but is definitely part of the Lower West Side neighborhood.  Basically, after the offer was accepted I became worried that I offered too high.  Is there anyone on here that knows west Pilsen/Heart of Chicago well?  I'd like some peace of mind that $600k on a gut rehab 4-flat isn't a crazy price.  It's hard to find comps for gut rehab 4-units in the area!
