Use the rate in the question. Rates are negotiable, not standard.

Set by the Texas Department of Insurance. Commonly a seller cost, but negotiable by contract.
Release of the seller's deed of trust and the buyer's deed. Not a percentage of price.
LTV is the loan over value. Down payment is the cash gap between price and loan.
Name the day-count method (360 or 365) and who owns the closing day before using the worksheet.
Seller debit, buyer charge, and total transaction math are different totals. No transfer tax in Texas.
The exam setup rule
- Name the topic for each line item before calculating it.
- Circle the base: sale price, loan amount, value, annual amount, or days.
- If seller days are not given, calculate the day count first.
- Calculate each line separately before combining totals.
- Label buyer charges and seller charges as separate buckets.
- Add only the bucket the final sentence asks for.
Five worked examples
$425,450 x 0.06 = $25,527 total commission.
Fixed dollar costs: $2,750 + $130 = $2,880. These do not scale with the sale price.
LTV: $340,000 / $425,450 = 79.92%. Down payment: $425,450 - $340,000 = $85,450.
$4,380 / 365 = $12 daily tax. $12 x 196 = $2,352 seller debit and buyer credit when taxes are unpaid.
Add seller-side commission, title, recording, and seller tax proration only if the question asks for seller math.
Traps to check
- Do not add a state transfer tax line. Texas has no state transfer tax.
- Do not combine buyer and seller charges unless the question asks for a total transaction number.
- Do not confuse loan-to-value (a ratio) with down payment (a dollar amount).
- Do not treat title or recording as a percentage of price. They are fixed dollar costs.
- Do not guess proration days. Derive seller days from the closing date and closing-day ownership first.
- Do not answer the first subtotal you calculate. Re-read the final ask.
Work it without the answer showing
Build separate buyer and seller ledgers. Label every amount as a debit or credit before calculating either final balance.

Answer key
- Commission is $25,527, points are $3,400, and unpaid-tax proration is $2,352. Seller credits are $425,450; seller debits are $286,167; seller net is $139,283. Buyer debits are $432,480; buyer credits are $352,352; buyer cash to close is $80,128.
- $3,650 / 365 = $10 per day. $10 x 120 = $1,200 buyer debit and seller credit because the seller prepaid taxes covering the buyer-owned period.
- LTV is $400,000 / $500,000 = 80%. Down payment is $100,000. Points are $400,000 x 0.015 = $6,000. Buyer debits are $510,000 and credits are $410,000, so buyer cash to close is $100,000.
Sanity check
- Every number should have a side: buyer, seller, loan, sale price, or day count.
- Commission should follow the sale price. Loan-to-value should follow the loan over value.
- Down payment plus loan amount should equal the sale price.
- A proration amount should equal daily rate times the exact days used by the stem.
- Seller-only totals should exclude buyer financing charges.
- If a number looks like a transfer tax, drop it. Texas has no transfer tax.
