Definitely would not rule it out!  

As long as it's not my deal or one I'm more than 50% owner then that should be okay, right?

It appears we can easily get the 1% rule out of SFR rentals (I haven't seen any duplexes in that county) in that area.3.)

It's a not an exact science but a great rule of thumb to quickly determine feasiblity of a rental.

Since your dad is a contractor, your saving 50%.

I don't think I would do it if I eventually had 50 units.

Please note I include a 40 to 50-mile radius from downtown as part of Chicagoland so this picks up part of Indiana.

The issue with land in general is its stark trickiness, there's no way to set a general rule of thumb as to what prices ought to be offered or what an approximate value would be, the reason?
