Duplex with Foundation Issue

[Austin Smith]

I'm considering buying this duplex. https://pittsburgh.craigslist.org/reo/6107512007.h...

It's almost completely gutted besides 1 kitchen and a bath. It's a 2/1 on each side. The back portion of the house is an addition, and the foundation is caving in. When I first saw this, I pretty much decided I was not interested. But after I talked to a foundation guy, he said it may not be as expensive as I think to fix. He came back with a $2700 price to remove the block and pour a new foundation with new supports so it shouldn't bow again. 

Here is a quick break-down of the costs I'm expecting:

Roof-6000

Electrical-7500

Foundation-4000(just going high here)

Drywall-4000

Flooring-3000

Plumbing-2000

Kitchen/Baths-10000

Misc-10000

So a total of around 50k in rehab costs. The only thing that scares me is the foundation. But if I could pick it up for 10k, I'd be all in at 60k. And I think the ARV would be around 100-110k. Rents would be around $1200 combined. Let me know your thoughts!
