What’s wrong with 100 year old houses? As a carpenter I can tell you that newer houses aren’t always better. A house that has survived 100 years of neglect has probably got good bones, while modern construction is often all about slapping stuff together as quickly and cheaply as possible in order to maximize profit for the developer. As one extreme example of newer homes not being better, in Connecticut there are 15,000 houses less than 10 years old that were recently condemned because the builders used bad concrete on the foundations. Many brand new houses I see being built in Colorado are built so poorly I’d much rather own a 100 year old brick house instead. I’ve seen brand new patios slope back towards the house, joist hangers attached with deck screws instead of nails, brand new roofs that leak, etc. there are a ton of hack builders out there creating problems for whoever buys the houses they build that’s why it’s recommended to hire an independent 3rd party home inspector even for new construction. I love old houses with big moldings, cool original details and some character. Cookie cutter subdivisions and contemporary designs aren’t my thing. There were some periods of really bad construction over the years and some questionable materials used, just learn to avoid that and do due diligence on any home new or old, at least on the old ones it’s easy to see if the foundation is going to sink or not, if it was gonna sink it would have started by now. I feel like some of the new materials being used today like MDF which is basically glued together sawdust will be looked back on in the future like what were they thinking to use that stuff. Even the new automation and internet of things houses that are controlled by apps, I don’t want to use my phone to adjust my thermostat. I’d rather put another log in the wood stove. I’d much rather have a 100 year old brick building with good bones (and updated electrical, appliances and plumbing) that was built by true craftsmen than a new stick framed house covered in glued together sawdust built with poor workmanship and controlled by smart phones but maybe that’s just me.
