He's spot on. If you've looking to the West or South of DTW, little to no traffic to deal with to get to the airport. Downriver (ie, close to the river/water) is cheaper, but for a reason - just not as nice. North of the airport is intense suburbs and I don't think you get a lot for your money. Yes, Ann Arbor is pricey, but it's got good schools, vibrant downtown and a nice town feel. Northville is nice, but more for the younger crowd or those without kids for some reason.

Dexter/Chelsea (which are west) is not too far from the airport and more rural - you can get a nice house with some acreage and have a nice lifestyle.
