Aside from the standard BR/BA count and square footage, I always focus heavily on the listing pictures for any comps I pull in my area - finding a comp that's as close to your property's condition and finishes will give you the best apples-to-apples comparison possible.I also wanted to second @Tim Swierczek's input: nobody in Minnesota likes moving in the middle of winter.

To avoid the risk management/insurance that comes with tenants' wood fire use:I'm thinking to seal the chimney cap on roof and run a cord putting an electric Infrared heater fireplace in there, so they can still open the glass and get heat and watch TV over the mantle, but can't burn anything or have any flame.
