Costs to Rehab - Pittsburgh (Help a new guy out)

Hello,

I may have come across a deal in the wider Pittsburgh surrounding area. It is a foreclosure for a good price, but it needs some work and this is my first time.

To help me run numbers, is anyone familiar enough to give me a rough cost per square foot for rehabbing/renovating in the outlying Pittsburgh areas? This house runs the chance of being a gut, but if I do it, I'd like to try it as a live and flip, so some upgrades could be stretched across about two years.

I'm weighing this versus a duplex further south and would appreciate some help from those who have worked in the area.

Also, any tips for getting comparable numbers? Right now I'm just looking at what Realtor offers, but I know I could have better data.

Thanks,
