Help me analyze this property in Allentown, PA

[Brian Stefanelli]

I am thinking about investing in Allentown, PA and would love some help with analyzing property.  

Here is an example of something I came across:

http://www.zillow.com/homes/for_sale/2122-W-Libert...

Can someone give me an opinion on why this is a good/bad investment?

I don't plan on buying it at this point but I need to know if my analysis is accurate so I can learn what to look for in the future.

I appreciate any feedback!
