the coop features I am awaare of are -- you pay cash for buying it and then through the year you pay a monthly fee to the cooperative towards the wrap-around mortgage ( that the building has ) and the property taxes that are paid on the whole property. Then at the end of the year you get a statement that tells you the percentage of you monthly amounts allocated to the mortgage interest and to the prop. tax. You sue these percentages to come up with your contribution to the deductible mortgage interest and to the property tax. That is how it works in MI
