This is a house that I’d tell others to run from, but since we already own it we’re just trying to determine best options.  

This was done to protect senior citizens on fixed incomes from being forced to sell their homes due to unaffordable property tax increases.Since the passing of this amendment, all properties in Michigan have two property tax values associated with them:State Equalized Value (SEV): supposedly equal to 50% of the market value of a property, not based on recent sales price.Taxable Value: the SEV annually capped as long as there is not a transfer of ownership.City Assessors are charged with determining how much property values have changed each year.

In a similar vein, how would you determine what "market rate" for your units are? 

You will also need to determine how much you want to raise.

Some people need 2% above the borrowing cost (8% cost of hELOC you gotta then make 10% + etc) and others will want to double their cost of capital or 200% so it depends.Everyone's going to give you their anecdotal experience or what their preferences are so its good to hear it all and determine your own.

I second this, if asking for the identification is for the sole purpose of verifying one’s identity then it’s not a violation of the fair housing act, however, if it were to verify someone’s citizenship or something that is not required in order to meet the housing requirements then it could be determined as housing discrimination .Quote from @Steve K.: Quote from @David Spurlock: Hey @Fareen E.
