​QUOTE: I need you to look at 2 properties and tell me how much it would cost to make the upstairs an apartment and the main floor and apartment.  Bones are already there, main floor you would need to extend bathroom to a full bathroom, make possibly the family room into master bedroom and walk in closet and laundry room.  Upstairs, would need kitchen, living, laundry and dining maybe a fireplace.
