How It Works

Title Insurance Explained

Title insurance protects property buyers and lenders against losses arising from defects in the title, such as liens, encumbrances, or ownership disputes.

Two Types of Policies

  • Owner policy: Protects the buyer for the full purchase price, lasts as long as you or your heirs own the property
  • Lender policy: Required by most mortgage lenders, protects only the lender for the loan amount, and decreases as the loan is paid down

    • Simultaneous Issue Discount

    When both policies are purchased at the same time, most title companies offer a significant discount on the lender policy (30-50% off). This is because the title search only needs to be performed once.

    Rate Variations

  • Rates are regulated in some states and negotiable in others
  • Typical rates range from $3.50 to $8.00 per $1,000 of coverage
  • Some states use flat-rate schedules while others allow market pricing

    • Worked Example

    $400,000 purchase with $320,000 loan, owner rate $5.50 per $1,000, lender rate $3.50 per $1,000, and 40% simultaneous issue discount on the lender policy.

    purchase_price = 400000loan_amount = 320000owner_rate_per_thousand = 5.5lender_rate_per_thousand = 3.5simultaneous_discount_pct = 40
    1. 01Owner policy: $400,000 / 1,000 x $5.50 = $2,200
    2. 02Lender policy (full): $320,000 / 1,000 x $3.50 = $1,120
    3. 03Simultaneous discount: $1,120 x 40% = $448
    4. 04Lender policy (discounted): $1,120 - $448 = $672
    5. 05Total title insurance: $2,200 + $672 = $2,872
