The pre-1981 cutoff is a useful approximation for the pre-FIRM/post-FIRM era in many Tennessee communities, but it is not the technically correct community-specific FIRM date for every address. We used it here as a consistent construction-age comparison.
| Construction group | Quotes | Median premium | Quotes over $1,000 |
|---|---|---|---|
| Built before 1981 | 33 | $599/year | 24% |
| Built in 1981 or later | 28 | $587/year | 25% |
| Zone AE group | Sample | Raw median | Median excluding quotes over $2,000 |
|---|---|---|---|
| Built before 1981 | 27 | $631 | $578 (n=21) |
| Built in 1981 or later | 14 | $858 | $617 (n=10) |
Even within Zone AE, older homes did not price worse. The raw medians tilted in the opposite direction because a few newer properties carried very high premiums. A 1935 Chattanooga home bound at $631, while a 2024-built property cost $9,304. A 2026 build received a $3,359 quote.
The finding is still useful: construction year by itself did not predict the expensive quotes. Elevation, foundation, distance to water, building value and carrier appetite were more informative.
| Metro area | Dataset size | Median or typical premium | Observed range | Main context |
|---|---|---|---|---|
| Chattanooga area | Largest Tennessee market | About $631 purchased | $325–$951 typical | Tennessee River and multiple creek systems; many Zone AE properties |
| Nashville area | 29 | $486 | $282–$3,537 | Cumberland River, Mill Creek and development near floodplains |
| Knoxville area | 7 | $609 | $275–$1,594 | Tennessee, Holston and French Broad river systems |
| Memphis area | 6 | $344 | $200–$753 | Mostly voluntary Zone X coverage in this sample |
Chattanooga, Hixson, Soddy-Daisy and Red Bank formed our largest Tennessee market. Among purchased policies, most premiums landed between $325 and $951, with a typical cost around $631. The metro also produced the highest purchased premium in the dataset: $9,304 for a high-exposure riverside property.
The Nashville-area sample included 29 quotes across Davidson, Williamson, Rutherford and Sumner counties, including Franklin, Smyrna, Murfreesboro, Hendersonville and Gallatin. The median was $486, and three out of four quotes landed between $300 and $950.
Knoxville's seven quotes had a $609 median. Because the sample is small, use that figure as a directional signal rather than a marketwide average. Availability can matter as much as price when private carriers change their appetite.
Video summary: Private flood insurance availability can tighten in a local market. Knoxville property owners should compare available private options with the NFIP and review policy terms, not assume every carrier will accept every property.
Five of the six Memphis-area quotes were in Zone X, with customers choosing coverage voluntarily. The sample had a $344 median and a $200–$753 range. The six-property sample is too small for a definitive metro estimate.

Every purchased policy in this dataset was placed with a private flood carrier or private program. None was written through NFIP Direct.
| Carrier or program | Policies placed | Share | Median premium | Range |
|---|---|---|---|---|
| CatCoverage | 14 | 44% | $325 | $193–$3,537 |
| Superior | 5 | 16% | $880 | $578–$1,872 |
| Argenia | 4 | 13% | $586 | $396–$831 |
| Sterling Underwriters | 2 | 6% | $585 | $570–$600 |
| TFIA | 2 | 6% | $582 | $520–$645 |
| Dual, Neptune, AON Edge, Johnson & Johnson | 1 each | 3% each | — | $599–$9,304 combined |
This is not a ranking of the cheapest companies. It shows which programs won the specific properties our agency quoted. Carrier appetite changes by property, construction, elevation, limits and risk model. A company that is competitive for one address may decline or price another address differently.
Use our guide to shopping NFIP and private flood insurance to compare more than the first-year premium.
Customers were much more likely to walk away when the quote crossed $1,000 per year:
| Outcome | Share above $1,000 |
|---|---|
| Purchased policies | 9% |
| Quotes not purchased | 22% |
A quote over $1,000 is a reason to investigate—not automatically a reason to go uninsured. Verify the building information, compare private carriers and the NFIP, and consider whether an elevation certificate or map review would add useful evidence.
Our resources on why flood insurance can be expensive in Zone AE and how to hire help for a LOMA or LOMR explain two common next steps.
These ranges are not quotes, but they can help you decide whether the number you received deserves a second review.
| Property profile | Dataset benchmark | How to interpret it |
|---|---|---|
| Zone X away from creeks | Median $300; low of $128 | Often at the lower end, but localized drainage and structure details still matter. |
| Rural Zone A near a small creek | Median $300 | The designation did not automatically create a high private premium in Tennessee. |
| Zone AE near a river or major creek | Median $602; many Chattanooga purchases $325–$951 | Expect more private-market sensitivity to elevation and water proximity. |
| Riverfront, low-elevation, commercial or high-value property | Several quotes from $1,600 to more than $10,000 | Compare carriers and terms carefully; outlier risk is property-specific. |
Compare private flood insurance options with the NFIP for your specific address, building and coverage needs.
Request a Tennessee flood insurance quoteWe analyzed 96 Tennessee flood insurance quotes recorded in our agency CRM from 2020 through July 14, 2026. The dataset contained 31 purchased policies and 65 quotes that did not close.
We excluded one home-insurance record, one duplicate quote record and one purchased policy with an unverifiable recorded premium. Year-built analysis used the 61 records that had both a usable premium and year built.
Important limitation: These are properties that contacted our agency, not a random sample of all Tennessee homes. The results describe our Tennessee book of business and should not be interpreted as an official statewide average.
For an official explanation of NFIP pricing, consult FEMA's Risk Rating 2.0 pricing page and methodology documentation .
Based on 96 real Tennessee quotes issued from 2020 through July 14, 2026, the median was $531 per year. About six in ten quotes fell between $250 and $700. Purchased policies had a median premium of $570.
No. Under FEMA's Risk Rating 2.0 methodology, flood zone is not an NFIP rating variable. The map still matters for lender requirements, floodplain management and understanding mapped hazards.
It can. In this Tennessee private-market dataset, Zone AE had a $602 median, compared with $300 for Zone A and $300 for Zone X. Each private insurer uses its own underwriting and rating model.
Not in this dataset. Homes built before 1981 had a $599 median, compared with $587 for homes built in 1981 or later. Both groups had nearly the same share of quotes above $1,000.
Among purchased Chattanooga-area policies in our dataset, most cost between $325 and $951 per year, with a typical premium around $631. High-exposure riverfront properties can cost much more.
A lender generally requires flood insurance when a building securing a federally backed mortgage is located in a Special Flood Hazard Area. Property owners outside those mapped areas can still buy coverage voluntarily.
Standard homeowners insurance generally does not cover damage caused by flooding. Flood coverage is purchased separately through the NFIP or a private flood insurer. Review our guide to flood insurance coverage for the basics.
Compare NFIP and private options, confirm that the building information is correct, review elevation and foundation details, and evaluate whether an elevation certificate or flood-zone review could add useful information. Compare coverage and exclusions—not only the first-year premium.
You came here needing a realistic Tennessee flood insurance benchmark. You now know that the median quote in our dataset was $531, the average was distorted by a small number of expensive properties, flood zone did not affect NFIP pricing but did show a difference in private-market results, and older homes did not carry a meaningful premium penalty.
Your next step is to compare the property-specific options. Read our complete NFIP versus private flood insurance guide , then request a quote when you are ready to see how your address compares.
The Flood Insurance Guru is a national flood insurance agency led by Chris Greene, a flood mitigation specialist with a master's degree in emergency management. The agency compares NFIP and private options and publishes original quote data to help homeowners, buyers, agents and lenders make informed decisions.
