The price of lumber is literally changing by the minute. In a single week in April, lumber prices fluctuated between $1,075.40 and $1,205.50 per 1,000 board feet. It’s not just lumber prices that have skyrocketed. Other homebuilding materials have as well. Crude oil, a starting point for paint, drainpipe, roof shingles and flooring, is up from $36.40 per barrel in October to $59.16 per barrel in March.
