New Construction and Homestead Cap: What First Year Homeowners Should Know

If you just bought a newly built home, your first year or two of appraisals can look confusing compared to what you'd expect from the 10% cap. Here's why, and what to actually check.

If you just bought a newly built home, or moved into a home you had built, your first year or two of appraisals can look confusing compared to what you might expect from the 10% appraisal cap. Here's why, and what to actually check.

This article is general educational information, not legal, tax, or appraisal advice. Always confirm your specific exemption filing date and cap start year directly with your county appraisal district, since exact timing can affect which tax year the cap first applies.

Why Your First Appraisal Can Jump Significantly

The 10% homestead appraisal cap only applies starting the year after you first qualify for the homestead exemption on that property. This means:

  • The purchase year (or the year construction is substantially complete) is not capped. The appraisal district can value the home at full market value in that first year.
  • New construction is often undervalued in the year it's built, since the appraisal district may only have partial information (an in progress build as of January 1, for instance), and then catches up to full value once the home is complete and sold.
  • The following year, once your homestead exemption is on file, is typically the first year the cap applies. Comparing year one to year two can show a large percentage jump that looks alarming but is often just the value catching up to where it should have been, before the cap starts protecting you going forward.

What to Check as a First Year Homeowner

  1. 1File your homestead exemption immediately after closing. This doesn't just reduce your taxable value, it starts the clock on the appraisal cap protection for future years. Don't assume it transfers automatically from a prior owner or gets applied without you filing.
  2. 2Confirm the appraisal district has accurate details on your build. New construction records are sometimes based on builder plans or permits rather than final as built specifics. Verify square footage, bedroom and bathroom count, and any options or upgrades are recorded correctly, since new construction records have more opportunity for error than an established home with years of accurate history.
  3. 3Understand that your purchase price is not automatically your appraised value, though it's often used as a strong data point. If your purchase price was below what the appraisal district assessed, that's a legitimate basis to protest using your own closing documents as evidence.
  4. 4Don't assume something is wrong just because year two's increase looks large in percentage terms. Compare the actual appraised value to genuinely comparable recent sales of similar new construction nearby, rather than reacting to the percentage change alone.

Common New Construction Protest Scenarios

My Home Was Appraised Above What I Paid for It

If your purchase was a true arm's length transaction (not a builder incentive heavy deal that might not reflect real market value, and not a below market sale to a relative), your closing statement is strong evidence for a market value protest.

The Appraisal Includes Upgrades or Options I Didn't Actually Get

Builders sometimes report a standard spec sheet to the appraisal district that doesn't match your actual build. Compare your final buyer's spec sheet or contract against what's listed on your notice, and file a correction or protest if there's a mismatch.

Comparable Homes in My New Subdivision Are Appraised Very Differently From Mine

New subdivisions built out in phases can have significant appraisal inconsistency between early and late phases, or between homes appraised before versus after full build out. This is a solid basis for an unequal appraisal argument once enough homes in the neighborhood have sold to establish a comparable data set.

Looking Ahead

Once your homestead exemption has been in place for a full year, your appraised value increases become capped at 10% annually going forward, and your protest strategy shifts toward the more typical approach covered in our other guides: comparing appraised value, not just market value, against similar nearby properties.

Frequently Asked Questions

Does the homestead appraisal cap apply in my first year of ownership?

No. The cap only starts applying the year after you first qualify for the homestead exemption on that property. Your purchase year, or the year construction is substantially complete, is not capped.

Why did my new construction home's value jump so much in year two?

New construction is often undervalued in the year it's built because the appraisal district may only have partial information. The following year often catches the value up to where it should have been, which can look like a large jump even though it's expected and not a sign of an error.

Can I use my purchase price as evidence in a protest?

Yes, if your purchase price was below what the appraisal district assessed and it was a true arm's length transaction. Your closing documents can be strong evidence for a market value protest.
