I guess I'd ask how you got a house without a microwave. I've never lived without a microwave, but I have never purchased a microwave either.
An oven, a microwave, and a fridge are the three appliances I have been able to count on always being present when I move in somewhere. Typically the microwave is build into the cabinetry.
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.
I think it's a regional thing. Every house I have owned came with the washer, dryer, fridge and stove. Even after I substantially upgraded the stoves in my first two houses, I left them there when I moved. Those houses were built in the 1950's and 1980's. Only my current house, built in the early 2000's came with a microwave.
OTOH, I'm told it's common in other parts of the country (I'm in the upper Midwest) to take major appliances when you move.
