Flood insurance in Texas averages $791 annually through the National Flood Insurance Program (NFIP), with rates varying based on location, home elevation, and construction. Texas doesn't mandate flood insurance, but lenders may require it in high-risk flood zones. NFIP policies cover structural and personal property damage but exclude basement damage, sewer backups, and detached structures. Private insurers may offer lower rates and higher coverage limits. Flood insurance is advisable due to frequent flooding risks.
