My current house was built in '82. Is that a new house? That's 41 years old at this point. Its a pretty average single family suburban build for the time, not anything especially fancy even for its day. Loads of houses we looked at in the area were built in the 70s and 60s and often had electric 240V appliances in the kitchen. That's about 60 years old, is that a new? A single car garage 1500sqft 3bdr house in a suburb sound like a high end house?

And yeah, my house is full of 120V circuits, but once again the house has 240V at the panel and could run 240V anywhere in the house if needed. As you pointed out, they probably do have a 240V plug for the dryer, ergo they've got 240V service at the property, so they could wire the kitchen if there's no wiring already. Once again, practically nobody has only 120V service at their home.
