Vicki, if you can tolerate a furnished apartment in the metro area, that would be your best short-term arrangement. Either pick up a copy of the Apartment Guide or visit the link below. I'm not aware of any furnished corporate homes for rent. Best of luck!
There are some rental properties on the Jackson MLS in the Madison area. If you are working with a realtor I would ask them to email me some of these listings. If not I would be glad to do so. You can call or email me and I will get that set up for you.
