I would be cautious if an older home has had upgrades inside very recently and then put on the housing market. I've seen waay too many shoddy remodels like that. I'd rather have an old home that has not been updated much, besides maybe some electrical and plumbing. Back when I lived in Mississippi we bought a house that was built in the 20's, it was electrified and plumbed sometime in the 40's. The wiring was old, but intact. A couple repairs to junction boxes and was serviceable for our needs. The plumbing was a different story, but its original install was wrong, as in sloped the wrong way for several feet. I was going to crawl under there and fix it, but needed to move back to PA quickly, so it never got done (and yes the new owners were aware of situation).
Come to think of it, the duplex we're in now that was built in the 90's has more questionable wiring than the knob and tube/cloth coated wiring in my old house, lol.
