Owning a home comes with tax perks. But are there unique advantages to buying a newly built home instead of a resale? The short answer: yes. Both have perks, but a newly built home might be the winner. Here’s what you need to know.

1) Construction Loans

  • Some buyers take out a construction loan, which converts into a permanent mortgage after building is complete.

  • Tax benefit: Interest paid during the first 24 months may be deductible.

  • Limit: Only for primary or secondary residences, up to $750,000 in mortgage debt ($375,000 if married filing separately) for loans originated after Dec 15, 2017.

2) Mortgage Deductions

  • Mortgage Interest: Deductible on loans up to $750,000 ($375,000 if married filing separately).

  • Mortgage Points: Prepaid interest equal to 1% of the mortgage; deductible in the year paid if IRS criteria are met.

  • Mortgage Insurance Premiums: Deductible within the same $750,000 loan limit.

3) Energy Efficiency Credits

  • Residential Energy Efficient Home Improvement Credit: Up to 30% of qualifying costs.

  • Annual limits (2023‑2025):

    • $1,200 for general improvements (windows, insulation, roofing, HVAC).

    • $2,000 for certain heat pumps, water heaters, biomass stoves/boilers.

    • Combined max: $3,200 per tax year. Up to 30% of qualifying costs.

  • New homes advantage: Some newly built homes may include energy-efficient systems, but many credits apply primarily to improvements on existing homes.

  • Products must have manufacturer certification to qualify.

4) Property Taxes

  • Deductible on both new and resale homes.

  • New construction edge: Taxes incurred during construction may also be deductible if paid in the same tax year.

  • Cap: Combined state and local tax deductions (SALT) are limited to $10,000 ($5,000 if married filing separately).

5) Quick Comparison: New vs Resale Home Tax Benefits

Bottom line: Newly built homes offer tax perks that can start even before moving in: deductible construction loan interest, energy-efficient features, and property taxes paid during construction. Resale homes offer many of the same deductions, but new builds often maximize early-year tax savings. Always check current IRS rules and consult a tax professional to confirm eligibility for your situation.
