Hey for Michigan where are you finding the rental lease agreements to use?
I used http://www.uslegalforms.com/
I joined RPOA (rental property owners association) it is located in Grand Rapids but they are service the whole state of Michigan. Well worth the membership fee for everything they offer.
Law Depot has state-specific leases.
Local associations that have forms that have been tried and tested in courts for years and that are updated and valid under Michigan law. (Be very wary of any other form you get online--most are not correct for use in Michigan.)
