Key Takeaways

  • Labor typically makes up 40%–60% of the total, so negotiating bids and prepping the space yourself can meaningfully move the number.
  • The project pays back best when it fits your home's style and your holding period. Check the ROI section before committing.
  • Always get at least three bids and verify contractor licensing before signing a contract.

Frequently Asked Questions

\n
\n
Most homeowners spend 5%–15% of their home's value on a whole-house renovation. Smaller scopes (single room) typically run $5,000–$30,000 depending on finishes and labor.
\n
Yes. Aim for at least three bids. Prices for the same scope can easily vary 20%–30% between contractors, and the lowest bid is not always the best value.
\n
Plan for 10%–20% contingency above your base bid. Older homes (pre-1990) typically need 15%–25% because hidden issues (plumbing, electrical, asbestos) are more common.
\n
This guide reflects national averages. For state-specific labor rates and material costs, use our state cost calculator or look up your region's prevailing wage data.
\n
Cash avoids interest but ties up liquidity. Financing options (HELOC, cash-out refinance, personal loan) can make sense if the renovation increases home value and you can comfortably carry the payment.
