What 96 Real Flood Insurance Quotes Reveal About Cost in Tennessee
A first-party analysis of premiums, flood zones, home age, metro areas, carriers and purchase behavior from quotes issued between 2020 and July 2026.
Tennessee flood insurance pricing was more property-specific than conventional wisdom suggests
This research case study was designed to answer a simple question: What do real Tennessee flood insurance quotes show when we look beyond broad national averages?
Across 96 quotes, the median annual premium was $531, while the average was $918 because a small number of high-exposure properties produced four- and five-figure quotes. Private-market results varied by flood zone, but home age showed almost no median premium difference. Customers were also much less likely to purchase when the annual premium exceeded $1,000.
First-party agency data from 96 Tennessee properties
The study includes both purchased and unpurchased quotes so the results do not hide expensive outcomes simply because a customer declined coverage.
2020 through July 14, 2026
Quotes were drawn from The Flood Insurance Guru's agency CRM.
31 purchased, 65 not purchased
Both outcomes were included to show the full range of quoted premiums.
61 usable records
Only records with both a valid premium and populated year built were included.
| Category | Count | Notes |
|---|---|---|
| Quotes analyzed | 96 | Tennessee flood insurance quotes after exclusions |
| Purchased policies | 31 | Policies recorded as purchased |
| Quotes not purchased | 65 | Quotes that did not close |
| Excluded records | 3 | One home-insurance record, one duplicate and one purchased policy with an unverifiable premium |
Seven findings that stood out in the Tennessee book
1. The median was $531
About six in ten quotes landed between $250 and $700 per year.
2. The average was $918
A small number of expensive properties pulled the mean far above the median.
3. Zone AE led private pricing
Its $602 median was roughly twice the $300 median in Zone A and Zone X.
4. Home age barely changed the median
Pre-1981 homes were $599 versus $587 for 1981-and-newer homes.
5. Chattanooga ran slightly higher
Purchased Chattanooga-area policies typically centered around $631.
6. One program placed 44%
CatCoverage placed 14 of the 31 purchased policies in this book.
7. Four-figure quotes converted less often
22% of unpurchased quotes exceeded $1,000, versus 9% of purchased policies.
What did Tennessee flood insurance actually cost?
Median and average tell different stories in this dataset. The median reflects the typical quote more clearly, while the average reveals the effect of high-risk outliers.
| Dataset | Sample | Median | Average | Range |
|---|---|---|---|---|
| All quotes | 96 | $531 | $918 | $128–$10,019 |
| Purchased policies | 31 | $570 | $940 | $193–$9,304 |
“Most Tennessee homeowners in this book did not face a four-figure premium. The expensive tail was real—but it was concentrated.”
Did flood zone affect pricing?
The answer depends on the market. Flood zone is not an NFIP rating variable under Risk Rating 2.0, but it still showed a measurable pattern in this private-market dataset.
NFIP
Flood zone does not directly set the premium under Risk Rating 2.0. FEMA prices the property using individualized risk variables.
Private market
Private carriers can still use flood zone in eligibility, underwriting and pricing. In this book, Zone AE had the highest median.
| Flood zone | Quotes | Median | Range |
|---|---|---|---|
| Zone AE | 60 | $602 | $250–$10,019 |
| Zone A | 10 | $300 | $193–$1,654 |
| Zone X | 19 | $300 | $128–$2,175 |
Did homes built before 1981 cost more?
Contrary to the common assumption that older flood-zone homes are always more expensive, the median difference was only $12 per year.
| Construction group | Quotes | Median | Quotes above $1,000 |
|---|---|---|---|
| Built before 1981 | 33 | $599 | 24% |
| Built in 1981 or later | 28 | $587 | 25% |
Zone AE only
Pre-1981: $631 median, n=27
Post-1981: $858 median, n=14
Zone AE excluding quotes above $2,000
Pre-1981: $578 median, n=21
Post-1981: $617 median, n=10
“In this dataset, elevation and property-specific exposure mattered more than the year on the deed.”
Caveat: Only 61 of 96 records contained both year built and premium. The post-1981 Zone AE subgroup was small, so that comparison is directional.
Research question 4
How did Tennessee metro areas compare?
| Metro | Sample | Median or typical premium | Range | Context |
|---|---|---|---|---|
| Chattanooga area | Largest Tennessee market | About $631 purchased | $325–$951 typical | Tennessee River and creek exposure; many Zone AE properties |
| Nashville area | 29 | $486 | $282–$3,537 | Cumberland River, Mill Creek and growth near floodplains |
| Knoxville area | 7 | $609 | $275–$1,594 | River junctions and a small directional sample |
| Memphis area | 6 | $344 | $200–$753 | Mostly voluntary Zone X coverage in this sample |
Chattanooga uses purchased-policy results, while the other metro figures are quote medians. This is useful directional context, not a perfectly uniform market comparison.
Which private programs placed the most policies?
Every purchased policy in the dataset was placed with a private flood carrier or program. The results reflect which programs won these specific properties—not a statewide ranking of cheapest carriers.
| Carrier or program | Policies | Share | Median premium |
|---|---|---|---|
| CatCoverage | 14 | 44% | $325 |
| Superior | 5 | 16% | $880 |
| Argenia | 4 | 13% | $586 |
| Sterling Underwriters | 2 | 6% | $585 |
| TFIA | 2 | 6% | $582 |
| Dual, Neptune, AON Edge, Johnson & Johnson | 1 each | 3% each | — |
What did purchase behavior reveal?
The data cannot prove why every customer declined, but four-figure premiums were substantially more common among quotes that did not close.
9% exceeded $1,000
Only a small portion of purchased policies crossed the four-figure threshold.
22% exceeded $1,000
High premiums appeared more than twice as often among quotes that did not close.
Implications for homeowners, buyers, lenders and agents
For homeowners and buyers
A flood zone letter or construction year cannot predict your premium by itself. Compare property-specific NFIP and private options before assuming a quote is final.
For real estate professionals
Obtain flood insurance pricing early in the transaction. A four-figure surprise near closing creates a greater risk of delay or abandonment.
For lenders
The map determines when coverage may be required, but it does not determine the NFIP rate. Borrowers may have multiple compliant coverage paths.
For media and researchers
The dataset provides a first-party view of quoted and purchased Tennessee flood insurance, including outcomes often omitted from published averages.
