Construction costs fluctuate with material markets, labor availability, and financing requirements.
Material and Labor Volatility
Lumber varied 385% (2020-2023). Labor accounts for 40-60% of costs and fluctuates 15-25% with cycles. Seasonal peaks add 10-15% in spring/summer. Verify material costs within 30 days of bidding.
Why it matters: Understanding this concept is essential for making informed investment decisions.
Financing Estimate Requirements
Hard money accepts preliminary estimates. Bank construction loans require detailed estimates with bids. FHA 203(k) requires HUD consultant estimates. Lender review takes 1-3 weeks.

Common Mistakes to Avoid
Using material prices from more than 30 days ago in estimates
Consequence: Volatile materials (lumber, copper, steel) can shift 10-30% in a month, invalidating the estimate
Correction: Verify material pricing within 30 days of bidding; lock pricing in contracts for key items
Not accounting for seasonal labor cost variations
Consequence: Spring/summer peaks add 10-15% to labor costs, creating budget overruns on warm-season projects
Correction: Factor seasonal pricing into estimates and consider scheduling renovations during off-peak months
