Duplex-my first analysis that looks worth anything

[Alison Koenig]

I don't plan on buying this property, I'm working on my analysis skills, so if anyone in Norwalk, CT likes it, go for it! That being said, IF I was ready I'd be jumping on this and I want some feedback on it, especially if I'm an idiot for even thinking it's a great deal. I want to learn as much as I can right now. TIA!
