Before accepting a take-home estimate for your Houston house sale, ask which property-tax figure is being used, what period it covers and whether it is final. A current-year proration, an overdue tax balance and money held by a mortgage servicer are different items. Mixing them together can make a good-looking offer comparison misleading.
A tax proration is the transaction’s allocation of an agreed share of taxes between buyer and seller. Your signed agreement and the closing team’s calculation matter. This guide is a worksheet for checking those assumptions, not a rule that every Cash As-Is agreement uses the same contract or allocates the same day to the same party.
Start with the bill, not the county value
The Texas Comptroller’s property-tax bill guidance explains that a current bill identifies the taxable property, applicable values, exemptions, rates and amount due. Those are different fields. An appraised value alone does not tell you the tax amount that will appear in your transaction.
For Houston-area property, identify the actual county, parcel and collecting offices. Do not assume a mailing city tells you every taxing jurisdiction or that one screenshot contains every account. Ask the closing team what it has verified and whether any current-year bill is still unavailable.
Our HCAD value versus cash-offer guide addresses the separate question of why a county value is not a buyer’s current purchase proposal.
Separate four entries before comparing offers
| Entry | Question for the closing team | Do not substitute |
|---|---|---|
| Current-year allocation | Which year, dates and calculation does the agreement require? | An old bill without identifying its year |
| Delinquent balance | What verified amounts and charges remain unpaid? | Only the original unpaid principal |
| Payment already made | Which account, tax period and receipt show it was credited? | A bank withdrawal with no matching account |
| Mortgage-servicer escrow | How will the lender reconcile funds it holds? | An assumed extra credit in seller proceeds |
If overdue taxes are part of the situation, use our Houston back-tax selling guide alongside this worksheet. A current-year allocation is not an explanation of a tax suit, foreclosure deadline or payment plan.
Make the estimate reproducible
Ask the closing professional to show the annual amount used, the allocated period, the day-count convention and the resulting debit or credit. Also ask whether the bill has been paid and how that payment changes the entry. The goal is to understand the calculation, rather than assume that a credit in one column is extra cash in your pocket.
Exemptions deserve a specific question. The Comptroller’s exemptions guidance explains that qualifying exemptions reduce taxable value and are administered through appraisal districts. Do not assume another owner’s future eligibility or use a neighbor’s bill to fill a gap. Ask which known exemptions and current information the estimate reflects.
Have the closing team explain how your agreement addresses any difference after the final bill is available. Identify who receives the bill, who is expected to make payment, what evidence is exchanged and whom to contact if the figures differ. Obtain advice about a disputed obligation rather than inventing a remedy from a blog.
A hypothetical seller-proceeds check
These invented numbers demonstrate arithmetic only. They are not a Houston tax rate, a quote or a prediction of your proceeds. Suppose a transaction assumes a $3,650 annual tax amount, 365-day basis and 180 days allocated to the seller. The calculated share is $1,800: $3,650 ÷ 365 × 180.
Now assume the applicable annual amount is instead $4,380 and every other assumption stays the same. The share becomes $2,160. That $360 difference affects the comparison even though the headline purchase price has not changed.
| Assumed item | First estimate | Revised example |
|---|---|---|
| Purchase price | $180,000 | $180,000 |
| Loan payoff | −$115,000 | −$115,000 |
| Allocated taxes | −$1,800 | −$2,160 |
| Other assumed seller items | −$2,200 | −$2,200 |
| Calculated proceeds | $61,000 | $60,640 |
Your transaction may use different dates, obligations and allocation terms. A change in closing date can also require a recalculation. Request an updated statement when material assumptions change.
Compare the complete sale, not one tax line
A cash proposal and a repair-and-list plan should use consistent known tax and payoff information. Then compare the expenses and timing that actually differ between the routes. Wider market exposure may produce a higher price; a current-condition purchase may reduce preparation and coordination. Neither route makes every tax obligation disappear.
Our cash-offer versus listing comparison helps organize that broader decision. If you request a Cash As-Is evaluation, share what you know about taxes and ask for a clear explanation of the proposed responsibilities. Check the closing estimate against the actual agreement before relying on a take-home number.
