Yeap, foundation is huge. Older homes might have limestone instead of cinder block as it didnt become standard until late 30's and just beyond. Limestone is ok, but it will break down over time and needs to be watched and maintained.
If the house has a wood foundation, just walk away. I dont care how cute the breakfast nook is. Get away from it now!
I don't know that I have ever seen a wood foundation before. Everything here has stone. Though some of the very old buildings have more of a crawl space situation, so no basement
