Calculating Closing Costs in Nampa

Nampa is in Canyon County — the same rate structure as Ada County, with ten title companies filing with the Idaho DOI. Here’s how to estimate your specific costs on a Nampa purchase.

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

Commissions (5.5%): $18,700

Escrow share: $550

Mortgage release: $15 (Idaho Code § 31-3205)

Prorated taxes: $1,000 (estimate)

Transfer tax: $0 — Idaho has none

Seller total: approximately $21,435 (6.3%)

Canyon County Rate Options

Per Idaho DOI 2025 Filed Short Term Escrow Rates: eight companies at $3.00/thousand, two at $3.50/thousand (two national underwriters). Choosing $3.00 over $3.50 saves $170 on a $340,000 transaction — same coverage, lower price.

Discounts

Simultaneous issue: $100 off. Reissue: up to 40% off the owner’s premium within 2 years (per IDAPA 18.05.01.013). Seller concessions: up to 3% of purchase price on conventional loans.
