Average. Which means lower than average for some and higher for others.Sorry the 100k number was primarily around the coastal metro cities. But even in cheap towns where a single family home is 100k total, an increase of 30k in just lumber material is a huge percentage increase of the total value.
More like 15k additional cost for 100k average price home and 45k additional for a 300k home. Or scale something along those lines.
Similar for higher prices in East (where real people live
) and West Coast.
