ZIP-level traffic congestion and accident rates. Dense ZIPs along I-10, I-45, I-69/US-59, Beltway 8, and the Grand Parkway often carry higher base rates than outlying suburbs.
Hurricane and flood exposure. Houston's coastal proximity drives higher comprehensive premiums in flood-prone ZIPs; carriers price for that exposure.
Vehicle theft rates by ZIP. Several Greater Houston neighborhoods carry higher comprehensive premiums tied to local theft data.
Vehicle make and model. SUVs, trucks, and frequently-stolen models often carry higher comprehensive premiums.
At-fault accidents and tickets in the last 3 to 5 years.
Coverage gaps. A recent lapse adds risk to most carriers.
Credit-based insurance score. Texas permits credit-based scoring, so credit history can affect your rate.
