Depending on your budget, there are lots of great rental options in Grand Rapids, and more being developed as we speak. As you move outward from downtown Grand Rapids, the options with the updates you're looking for might be fewer, but the prices should certainly be better.
If you've tried your luck with searching here on Trulia, Zillow, Craigslist, RentGR.com and the like, and need some additional help, let me know. We can talk about additional tools I'll have as a Realtor, the most important of which may just be the time I can put into your search and the love I have for doing it.
I have a two bedroom/1 bath in Grandville with a lot of modern updates. Feel free to shoot me a message if you would be interested. I also have it listed in my rental listings section.
