It was not just the increase in lumber.
Everything went up in price:
Labor
concrete
windows
doors
appliances
carpet
flooring
electrical romex and components
rebar
plywood
osb
cabinets
roofing
drywall
basically every component to new home construction
Just this week I was told by a customer in northern Idaho that a big job was delayed because the local concrete companies could not get enough Portland Cement
I keep hoping prices will drop back down so I can become a homeowner again, but all the “experts” keep saying home prices will never fall again.
