Michigan State has alot of house moving going on. Most of the older frats/sor have established housing. Some of the new and smaller chapters however do the move up whenever possible. Houses are scattered all over the place, so there isn't really a greek row, but there definitely isn't room for one either because there are soooo many chapters. I've heard the university is planning to buy up an entire block of old student housing, which also encompasses a couple of frats. So far I haven't heard of any plans to help these frats rebuild.
My sorority, Sigma Alpha, did the move up. Our landlord at our very first house loved our chapter. When he had a MUCH bigger house come available we were offered first. He worked with the chapter to create a budget for the lease, and he did a bunch of remodelling. This house is really awesome, it topped all of our expectations.
