I will continue to evaluate my plan as time goes on and remain flexible, as many people advocate as being key.  

Just got back from looking at a 4plex in a suburb of Chicago (nice neighborhood). Building is completely tenant occupied with 3-2bedrooms and 1-1bedroom, unit comes with new boiler, water tank and new coin operated wa...

That is what I found in Chicago too but I haven't spent a ton of time evaluating properties there yet. 

I can send you performance evaluations or links to several past deals to check out! 

.- On the surface, 17 occupied lots for $250k doesn’t seem crazy but there are many other factors to evaluate, such as: —> Are lot rents $200+/month?  

Every really successful investor of these towers evaluates the property independently.

You must also evaluate what B's possible Chapter 13 bankruptcy would mean, in terms of not being able to foreclose and in terms of having legal fees. 

Overall, i'm thrilled with the possibilities of this house and its location - and I really want to evaluate this thoroughly but not sure how to calculate this ceiling/roof situation.Any thoughts?

The agent said that the seller is liquidating his portfolio to move and retire.I am evaluating this based on NOI and cap rate like a normal commercial property, but some of my research says to evaluate it based on price per unit as well.

Don't do that...You have to remember that every investor looks for something different in the data on the deals they evaluate.
