Understanding Texas Title Insurance Rates
In Texas, title insurance premiums are not determined by individual title companies. Instead, they are strictly regulated by the Texas Department of Insurance (TDI). This means that regardless of which title company you choose, the "Base Premium" for your policy will be exactly the same based on the coverage amount.
The rates are known as "promulgated rates." These rates act as a tiered system, decreasing per thousand dollars of coverage as the property value increases. This calculator uses the official formulas provided in the Texas Title Insurance Basic Premium Rates (Rate Rule R-1).
How the Rate Calculation Works
The calculation is cumulative based on the value of the property (for an Owner's Policy) or the loan amount (for a Lender's Policy). Below represents the tiered structure used for the calculation:
Policy Amount Range
Rate Calculation Logic
Up to $100,000
Base rate starts at $238 (min) and scales up to $832 at $100k.
$100,001 to $1,000,000
$832 base + ($5.27 per $1,000 over $100k)
$1,000,001 to $5,000,000
$5,575 base + ($4.33 per $1,000 over $1M)
$5,000,001 to $15,000,000
$22,895 base + ($3.57 per $1,000 over $5M)
$15,000,001 to $25,000,000
$58,595 base + ($2.54 per $1,000 over $15M)
Over $25,000,000
$83,995 base + ($1.52 per $1,000 over $25M)
Simultaneous Issue
If you are purchasing a home with a mortgage, you will typically need two policies: an Owner's Policy (protecting you) and a Lender's Policy (protecting the bank). In Texas, if these are purchased simultaneously, you do not pay the full premium for both. You pay the full premium on the Owner's Policy, and a nominal fee (usually $100) for the Lender's Policy, provided the Lender's coverage does not exceed the Owner's coverage.
Who Pays for Title Insurance in Texas?
Who pays the premium is a negotiable term in the real estate contract. In many Texas markets, it is customary for the seller to pay for the Owner's Title Policy, while the buyer is responsible for the additional cost of the Lender's Policy (typically the $100 simultaneous issue fee) if applicable. However, this varies by county and specific contract negotiations.
