<p>I can pretty much confirm that the residency plan WILL NOT work so if the OP does not want to pay Out of State Tuition to attend U Mich he/she may wish to consider another plan. Having been through the residency process, I can assure the poster that U of Mich has one of the most rigorous residency requirements of all schools and that living with grandma is old hat to them. (Just those kinds of attempts are what caused U of Mich to ratchet up its policy.)</p>
