Check out some small towns if you want to see pre war homes. I almost bought a craftsman but ended up with a house built sometime around 1900 (the documents I've seen list varying dates) it got an expansion in the 40s and a detached garage in the early 50s, and at some point someone enclosed the porches creating some nice mud rooms and the main floor bathroom appears to have been redone around the 80s or 90s.

My in-laws lived in a 19th century log cabin which had seen several expansions and renovations over the many decades it stood. Ultimately that was it's downfall though as some old electrical wire caught fire and as it burned the fire just got stuck deep in the layers of wall and ultimately had to be knocked down in order to put out the fire

Most prewar homes that are still standing have seen many expansions and updates and as such are just teaming with character and charm
