Rather than go to war with costly litigation, consider an alternative that goes like this:The parties agree to accept appraised value as the valuation method The parties agree to who selects the appraiser and agree to split final appraisal costs The first appraisal comes in at a value that is acceptable to the first party but doesn’t meet the approval of the second party The second party chooses its appraiser and the parties still don’t agree on value The parties agree at the outset that if neither parties appraised values are acceptable to them, the first two appraisers select a third appraiser and agree at the outset that the valuation of the third appraiser is final Basically this approach to setting value has been called “my appraiser, your appraiser,Their appraiser Best of luck sorting this out

For all those following along...writing a lease condition that is in conflict with State civil code/law/order etc does not create a legal obligation on the tenant.

currently we are in litigation with Lima.  

This is easily litigated; we have 2 military police protection dogs, highly trained K9's, about $80,000 in total (and no, you can't finance dogs, you have to write a check).

A shortage of litigation and someone peaking over one's shoulder doesn't give anyone the excuse to break the law.I now decend from my soap box.

I'm a Civil Engineer.

@Bruno Alhasson this will not be easy to address.Yes, Michigan has laws that make squatting a felony.PROBLEM: the police have "better things to do", so will do everything they can to avoid getting involved and claim it's a "civil matter" - meaning you have use the court system to evict them.If you know what you are doing and contact the Neighborhood Precinct Officer, you have about a 50/50 chance of them helping you.Otherwise, hire an experienced eviction attorney!

I assume a 'Civil Case'  is similar to Small Claims?

Landlord and tenant end up in expensive litigation for years.  

As a current civil engineer, usually a scope of work is needed for any construction related project and a clause that I love to put in is a schedule penalty.
