Is this a good deal. Looking for a second set of eyes

[Robert Fountain]

I'm looking to make an offer on my first deal.  It's a 4 unit building with each unit having 1 BR / 1 BA.  The analysis is below.  The rent is a bit below market right now but all 4 units are occupied.

The house is listed at 170K but it's been on the market for a while and the agent thinks they will go much lower.  130K seems to be the numbers that will work for me.

Thanks in advance.
