The prices, while not easy pickings, are much better than Denver, and I think there's still room for some good appreciation.

Finding buyers pretty simple. 

Really, anyone that is willing to let me pick their brain a little bit and come see their projects in person.

*note - this is assuming I can find the same deal as my second (just to keep it simple).

Pick a solid B-Class suburban area.

I've found that, once a property hits any list, it's already picked over and there's competition because others also have the list.The best wholesale deals are properties you can buy very cheap in order to resell low enough that an investor can buy it from you and still make their own profit.

So here’s what I think you should to: pick two actual cities and optimize around “want”.

For simple math, $80K/2 buildings = $40K per unit.

We are new to this, initially we built the office for ourselves to use, but after retirement is presently rented .ORKeep it simple (KISS), pay about 120k in taxes (pay forward) and then invest the net proceeds of S 600k .  

Currently at this time this area is not desirable and this is only an opinion of mine, but if this plan picks up speed and the city of Milwaukee decides to revitalize it wouldn't it be something you wish you had invested in?
