I kept it simple enough when I bought a commercial building. Its in an industrial area, a long building with 10 units, lots of parking space around back, some street parking out front. Each unit has an office area up front, and then a large rectangular area in the back that can be customized. A bit of everything is in there, from a kitchen cabinet shop, auto repair, wholesale bearings store, appliance repairs, to a gym for people who work in the area. It has been a blessing and great tenants.
