What I know of Greenfield is that they have a large manufacturing base for job prospect, so should be plenty of renters. 

I learned a ton about construction and permitting.

An S corporation is not permitted to generate more than 25 percent of its gross receipts from passive income in any given year if it has accumulated earnings and profits.

You need to call the assessors office and building and permits to dig for info.If the 3 plex is grandfathered in or was never allowed to begin with then you can't buy based on the seller shown cash flow model because if you will not be allowed to do that you will not make that gross income for rents.You need to see if it is even allowed and then if it was remodeled is it up to code and permitted??

Areas that I know on an intimate level would be Arlington Heights, Prospect Heights, Wheeling, Mount Prospect, and Palatine.

glad to be of help :)I also agree that concord has better appreciation prospects than inland areas, as it's more central to SF and Silicon Valley, plus BART access is a big plus.Good luck!

The place is going to need 25-30k of renovations to make the place livable and to past permits .

Looking at a property that has 3 units on it but only 2 are permitted.

Creating an air of confidence for your prospective tenants can be a tipping factor in them choosing you over another landlord.
