Apparently the previous owner didn’t feel the need to have one either. Note that we are discussing a house that was rebuilt from a barn in 1938 (no one really knows how old the barn was at the time). There are no kitchen cabinets into which a microwave might be built, just open shelves, which I find quite satisfactory.

When I redo the kitchen, I’ll add a range hood, but the next owner will also be buying a house without a microwave.
