Reletting Fee (Michigan lease break fees)

[Colin Petzold]

This is my first BP forum post and it is in regards to Michigan law on lease break fees in Michigan. It is my understanding that in the case your tenant breaks a lease contract early, as a landlord, you can only charge the tenant up until the apartment is re-rented (+ any expenses incurred like marketing the apartment)

Can anyone speak on the legality of reletting fees in Michigan (ie the costs the landlord faces due to an early termination) and how a landlord is to come up with this number to push onto the tenant? For example, could the reletting fee simply be "1 month's rent" which would be charged in addition to the rent for the time until the apartment is re-leased? In short, looking for the most effective legal way to deter lease breaks.
