>saw a stat saying average new house had $24,000 added cost from higher lumber prices.
LJ, that's an older stat. Most recently (a few weeks ago) economists for the NAHB.org (National Assn of Home-Builders) calculated the extra cost for avg size home to be an added $36,000.... And that stat is already obsolete, because lumber prices jumped an extra 15%-20% since the calculations were done.
I build some big arse houses. 4000 sq ft house adds $80-100K for me. 7/16” osb at $49 , last year $8-10. I use 400 plus in a house. Thats just one item. I am adapting to more concrete build. It used to be 20-30%. Not any more.
