Buyer Cost Calculation
For a $340,000 home, $272,000 loan (80% LTV), $3.00/thousand rate:
Lender’s title insurance: $272,000 ÷ 1,000 × $3.00 + $150 – $100 simultaneous = $866
Loan origination (0.75%): $2,040
Appraisal: $500
Inspection: $400
Recording: $15 + $45 = $60 (Idaho Code § 31-3205)
Prepaid items: $2,400
Buyer total: approximately $6,266 (1.8%)
At $3.50/thousand (companies filing at $3.50): lender’s insurance increases to $1,002 — $136 more.
Seller Cost Calculation
Owner’s title insurance: $340,000 ÷ 1,000 × $3.00 + $150 = $1,170

Escrow share: $550
Mortgage release: $15 (Idaho Code § 31-3205)
Prorated taxes: $1,000 (estimate)
