Where to search 2-4 units in Michigan?

[Zach Schwarzmiller]

I have a friend who asked me where he could search 2-4 unit properties to purchase in Michigan. I told him to check out Redfin, as people without MLS access have pretty good luck with that in Seattle; however, he said it hasn't really caught up there yet. Is anyone in Michigan using a website that doesn't require MLS access to view 2-4 unit properties? Thank You,
