What drives the risk for expensive homes in Tennessee
- Catastrophe exposureTornadoes are Tennessee's signature catastrophe. On the night of March 2-3, 2020, ten tornadoes touched down across the state, including an EF-3 that tracked more than 60 miles across the Nashville metro area east to Smith County and an EF-4 that struck between Baxter and Cookeville. The storms moved at up to 65 mph. Source
- FloodOn May 1-2, 2010, Nashville received 13.57 inches of rain, more than double its previous two-day record, and the Cumberland River crested at 52.55 feet downtown on May 3. The flooding killed 18 people in Middle Tennessee and caused damage in the billions. Flood is excluded from homeowners policies, and NFIP building coverage stops at $250,000, so expensive homes near Middle Tennessee rivers and creeks may need excess or private flood coverage. Source

When the standard market says no, and what earns credits
- Insurer of last resort and wind poolsTennessee does not have a FAIR Plan: it is not among the states in the 2024 FAIR Plan data compiled by PIPSO and published by Triple-I. A home the standard market will not insure generally goes to the surplus lines market. Source
- Mitigation credits and programsTennessee has adopted the 2018 International Residential Code. The State Fire Marshal's office enforces it for one- and two-family homes where the local government does not enforce its own codes, but a city or county can opt out of state residential codes and enforcement by a two-thirds vote of its legislative body.

Worth knowing in Tennessee
Earthquake is excluded from standard home policies and must be bought separately, which matters most in West Tennessee near the New Madrid Seismic Zone. The Department of Commerce and Insurance cites a 25 to 40 percent chance of a magnitude 6.0 or larger earthquake in the central United States within 50 years, and says earthquake deductibles are usually 10 to 20 percent of the coverage limit.
