TAX INFO FOR NORMAL PEOPLE
A plain-English look at Rockwall CAD property-tax and appraisal records for 1602 Mariah Court, Heath, TX 75032, including CAD market value, appraised value, exemptions, taxing entities, improvement records, and value history.
View Official Rockwall CAD Property Record
1. CAD Big Picture: Land + Improvements = Market Value
This shows what the CAD market value is made of. Appraisal districts usually separate value between the land and the improvements. Improvements may include the home, garages, shops, patios, pools, decks, storage, and other structures.
Land Value $200,000 + Improvement Value — = CAD Market Value $200,000
3. Current Tax Exemptions & Statutory Limitations
Property tax bills reflect two distinct types of CAD adjustments: local taxing jurisdiction exemptions (which reduce taxable value below appraised value) and statutory appraisal limitations (which limit the annual growth of appraised value itself). Each taxing entity establishes its own exemption amounts and tax rates.
No standard exemptions or CAD reductions were detected in the current record.
Each taxing jurisdiction may apply its own exemptions, limitations, and taxable-value adjustments. The figures shown reflect the current CAD record. Specific exemption details are displayed when available from the source. A buyer’s exemptions and future tax obligations may differ.
4. Value After CAD Reductions
This is where CAD reductions, exemptions, limitations, or special-use valuation may affect the value used for tax calculations.
CAD Market Value $200,000 − All Current CAD Reductions $0 = Current Taxed Starting Point $200,000
This reflects the CAD net appraised value after current CAD reductions. Individual taxing units may use different taxable values when exemptions apply.
5. Who Taxes It?
These are the local entities included in the current CAD/tax estimate. A property tax bill can include a city, county, school district, municipal utility district, public improvement district, or other special district. Each entity may use its own taxable value, rate, and exemption treatment.
| Entity | Taxable Value | Rate (per $100) | Est. Tax (No Ex.) | Savings | Est. Tax (Current) |
|---|---|---|---|---|---|
|
City
CITY OF HEATH |
$200,000 | 0.2757 | $551 | — | $551 |

County
ROCKWALL COUNTY |
$200,000 | 0.2510 | $502 | — | $502 |
|
School District
ROCKWALL ISD |
$200,000 | 1.0669 | $2,134 | — | $2,134 |
Each taxing jurisdiction may apply its own exemptions, limitations, and taxable-value adjustments. The figures shown reflect the current CAD record. Specific exemption details are displayed when available from the source. A buyer's exemptions and future tax obligations may differ.
6. Estimated Tax Bottom Line
Est. Taxes (No Exemptions) $3,187 − Est. Tax Reductions / Savings — = Est. Taxes (With Current Exemptions) $3,187
The current CAD record does not establish an exemption tax savings calculation. A buyer’s future tax bill may differ.
7. CAD Values Over Time
YOY Change reflects the change in CAD Market Value from the prior appraisal year. Taxed / Appraised reflects the CAD net appraised value after CAD reductions, or the certified capped appraisal value where jurisdictions differ. Individual taxing units may use different taxable values when exemptions apply.
| Year | Land | Impr. | Market | Taxed / Appraised | YOY Change |
|---|---|---|---|---|---|
| 2021 | $165,000 | — | $165,000 | $165,000 | +$50,000 / +43.48% |
| 2022 | $200,000 | — | $200,000 | $200,000 | +$35,000 / +21.21% |
| 2023 | $210,000 | — | $210,000 | $210,000 | +$10,000 / +5.00% |
| 2024 | $200,000 | — | $200,000 | $200,000 | -$10,000 / -4.76% |
| 2025 | $200,000 | — | $200,000 | $200,000 | — |
| 2026 | $200,000 | — | $200,000 | $200,000 | — |
8. List Price vs CAD Value
The current list price and the county’s CAD market value are not the same thing. CAD market value is used for property-tax context and may lag the open market, reflect prior protests, exemptions, caps, agricultural or special-use treatment, or other appraisal district methods.
How does the list price compare with the CAD value?
CAD values are appraisal-district values used for property-tax purposes and can differ from current asking prices and eventual sale prices.
Current List Price $1,349,900 − Current CAD Market Value $200,000 = Over CAD Value +$1,149,900 (+575.0%)
A sale price can become part of the appraisal district’s future evidence. A buyer’s future taxable value and tax bill may change after purchase, especially if exemptions, caps, or special-use valuation change.
For tax planning, buyers should confirm future taxable value, exemptions, and special-use treatment with the appraisal district, tax office, lender, CPA, or other qualified advisor.
