Douglas,
Take a hard look at Northwest, Indiana. NW Indiana is NOT Indianapolis. It's basically suburbs of Chicago. Generally speaking, the commute time to downtown Chicago is about 30 minutes. There are a tremendous amount of people that have moved from Illinois, over to NW Indiana. Why? Because the taxes are much lower, cost of living is lower, quality of life is great and home acquisition prices are lower than Illinois. However, the rental rates aren't much lower than Illinois. So your cash on cash return is very good. Plus the area is growing, due to the exodus out of Illinois. That can only help home prices rise. Take a look at cities such as: Crown Point, Merrillville, Hobart, Griffith, Highland, Hammond and many others. Crown Point is mostly for flipping, but can also be a great rental area. It's mostly upper income. The other cities are good for rentals and some are also good for flips as well. Best of luck to you.
