Never compare homes on principal & interest alone. Compare the full expected payment, with a realistic tax estimate for the completed home, including any MUD or PID on the lot.

1. The payment on the flyer may not be the payment you keep
New homes are often quoted using a tax figure tied to land or a partially built home. Once the county values the completed house, the tax portion of your monthly payment can rise. The quote isn't necessarily wrong, it just may not describe the home you'll actually live in.
2. Three numbers set your tax, and they are not the same number
They're connected, but each is set by a different party. Confusing them is where most surprises begin.
| Number | What it is | Who sets it |
|---|---|---|
| Purchase price | What you agree to pay the builder | Your contract |
| Expected appraised value | What the county expects the completed home to be worth for tax purposes, related to price, but not identical | The appraisal district |
| Combined tax rate | School district + county + city + any MUD or PID, expressed as one rate | Each taxing entity |
3. Land today, house tomorrow
The appraisal district generally values the land and any improvements that exist as of January 1. A home that's incomplete on that date may appear at a partial improved value rather than its eventual completed value, so a quote built on that partial value understates the settled tax. Not every purchase follows this pattern; your timing depends on when the home is finished relative to the appraisal date.
4. Two things can push your payment up
When a monthly payment increases after move-in, it's usually one, or both, of these. They're different, and the fix is different.
Ask your lender which is which. Knowing the split tells you what your settled payment will look like.
5. MUD vs. PID: know which applies, and verify it
Both are common in new communities. They are not the same, and they show up on your bill differently.
| MUD, Municipal Utility District | PID, Public Improvement District | |
|---|---|---|
| Usually | A value-based property tax | A property-specific assessment |
| Amount | Rate adopted annually | Amount and term depend on the assessment plan |
| Verify | Current debt, rate, exemptions, service responsibilities | Balance, annual installment, term, prepayment rules |
6. Run the math (one minute)
Estimated annual taxes = estimated taxable value × combined tax rate (as a decimal). Rate as a decimal: 2.8% = 0.028.
| Line | Your number | |
|---|---|---|
| A | Expected completed value (what the finished home should appraise at) | $__________ |
| B | Combined rate as a decimal (all districts, e.g. 0.028) | 0.________ |
| C | Estimated annual taxes (A × B) | $__________ |
| D | Estimated monthly taxes (C ÷ 12) | $__________ |
| E | Amount used in your lender quote | $__________ |
| F | Potential monthly difference (D − E) | $__________ |
7. Where to verify each number
Each figure in your payment has an authoritative source. Confirm them independently, builder or lender marketing is a starting point, not verification.
| Source | What to confirm |
|---|---|
| County Appraisal District | Appraised value and whether the home is recorded as complete |
| Tax Office (Assessor-Collector) | The combined adopted rate and the actual tax statement |
| TCEQ / District Records | Whether a MUD applies and its official filings |
| PID Documents | The service & assessment plan, balance, and installments |
| Your Lender | The exact value and tax figures behind the tax line in your quote |
| Title Documents | What the closing paperwork discloses about MUD/PID |
8. 10 questions before signing
Print this and bring it.
9. Three situations, three lessons
| Situation | Lesson |
|---|---|
| Comparing communities, two homes at the same price, one in a MUD/PID | The monthly payments are not the same. Compare the full expected payment, not the sticker price. |
| Incomplete assessed value, quote used land value, home finished after Jan 1 | Estimate taxes on the completed value so the later bill isn't a surprise. |
| Escrow shortage + future collection, payment jumped for two reasons at once | Ask which part of an increase is ongoing (higher taxes) and which is a one-time catch-up. |
10. The five numbers to verify before you trust a payment quote
- Expected appraised value of the completed home, not land.
- Combined tax rate, all districts, as a decimal.
- Tax figure used in your quote, ask what value and rate produced it.
- MUD rate and/or PID installment, if either applies to your lot.
- Escrow amount and any shortage, ongoing cost vs. one-time catch-up.
