Tennessee housing market: reading the state and city data

This page publishes no market statistic. Not a median, not a change on the year, not a days-on-market figure, not a forecast. That is deliberate, and it is the most useful thing a page like this can do, because by the time any of those numbers reaches an article they are describing a period that has closed, a geography you probably do not live in, and a measure most readers have been mis-sold.

What this page does instead is teach you to read a market claim. After this you should be able to take any sentence beginning "the Tennessee housing market is…" and work out, in about a minute, whether it means anything.

1. Before any number: period, source, geography

Three questions, always in this order. If a claim cannot answer all three, it is not evidence.

• What period does it describe, and when was it published? These are different dates and the gap between them is often months. A statistic about a quarter that ended in March, published in June, read by you in October, is a year old in everything but its headline.
• Who produced it, and from what transactions? Every source covers some transactions and misses others. The omission is usually the interesting part.
• What geography is it? A state, a metro area, a county, a city, or a set of postcodes. These nest inside each other and they do not behave alike.

2. What each measure actually is

Median sale price is the middle of the prices that closed in a period. It is not the value of a typical house and it is not an average. It moves when the mix of what sold changes, with no change in any individual property's value: a quarter in which more large new-build houses close will show a higher median even if nothing anywhere became more expensive. Read a change in the median as a change in the market only after you have ruled out a change in the mix, which most published commentary does not do.

Median list price is a measure of what sellers are asking. It tells you about seller expectations and about what is currently unsold, which makes it a description of the leftovers rather than of the market.

An automated valuation — the on-screen estimate attached to an address on a listing portal — is a model output, not a price and not an appraisal. It is produced by an algorithm from public records and prior sales, it carries an error range, and it has never seen the building. Use it to notice that a number exists, never as the number.

Inventory and months of supply. Inventory is how many homes are listed at a moment. Months of supply divides that by the rate at which homes are selling, which makes it the more meaningful of the two, and it is also the one most sensitive to how the counter defines "active".

Days on market is the time between listing and contract, and its definition varies by who publishes it: whether it resets when a listing is withdrawn and relisted is a choice, and that choice changes the number.

Price per square foot is only comparable between buildings of similar type, age and condition on similar lots. Across those differences it is arithmetic without meaning.

3. Why a statewide figure tells you nothing about a street

Tennessee runs from the Mississippi River to the Appalachians and contains everything from the state's largest consolidated city-county to small incorporated places. A single statewide number is an average across all of it, weighted by wherever the most transactions happened to be. It cannot rise or fall for the street you are considering, because it was never about that street.

The narrowing is the whole job. State, metro, county, city, and then the actual comparable sales for the property type you want within a short distance and a recent window. Each step down is a smaller sample, so it is noisier and more honest at the same time. Tennessee REALTORS, which compiles the statewide monthly snapshot, says so itself: "While all real estate is local, Tennessee REALTORS compiles statistics to provide a snapshot of the statewide residential market. You may also want to contact your local association for specific market statistics."

Want to see what is actually listed? This site has no listings and runs no search. Recently sold homes in Nashville on Zillow — recent closings are closer to evidence than asking prices, but confirm anything you rely on against the county register of deeds.

4. The sources, and how current each one really is

Ordered roughly from most primary to most processed.

1. The county register of deeds. Recorded deeds are the actual transactions. This is as primary as it gets, and it is public. The trade-off is that it is one parcel at a time and the recording itself lags the closing.
2. The county assessor of property. Holds parcel records, characteristics and sales used for assessment. The Tennessee Comptroller's Division of Property Assessments also publishes a statewide property assessment data search and a county-by-county assessment index. Note that an assessor's appraised value is set on a reappraisal cycle — the Comptroller states counties run on a six, five or four year cycle — so it is not a current market value, and how appraisal, assessment and the tax bill fit together explains why the two are different numbers.
3. The FHFA House Price Index. A repeat-sales index built from mortgages purchased or securitised by Fannie Mae and Freddie Mac since 1975, published monthly and quarterly down to state, metro, county, postcode and tract level. Because it tracks the same properties over time, it is largely immune to the mix problem that distorts medians. Because it only sees conforming conventional mortgages, it does not see cash sales, jumbo loans or most government-backed lending.
4. Tennessee REALTORS. Publishes a monthly statewide residential snapshot, with earlier months archived. Compiled from member transactions, which means sales outside that reporting are not in it.
5. The U.S. Census Bureau's American Community Survey. Housing tenure, values and costs. One-year estimates cover areas of 65,000 people or more and are the most current; five-year estimates cover every geography including census tracts and are the more reliable, at the cost of describing a sixty-month window. The Bureau's own guidance is to use one-year data when "currency is more important than precision" and five-year data when "precision is more important than currency".

Two habits will keep you out of trouble. Write the vintage next to every figure you copy. And never compare two figures from different sources, because you will be measuring the difference between their methods and calling it a market movement.

5. What the data can and cannot decide for you

It can tell you the general direction of a large area over a long period, whether a specific asking price is unusual against recent closings of a similar property nearby, and roughly how long similar homes have been taking to go under contract. It is genuinely useful for those.

It cannot tell you what a particular house is worth, what will happen next, or whether now is the right time for your household. The first of those needs an appraisal and an inspection; the second is a forecast, which this site does not publish; the third is a question about your own circumstances, not about the market. The purchase process from offer to closing and preparing and pricing a Tennessee home for sale are where that reasoning actually gets applied.

6. How this page is maintained

This page carries definitions and sources, which change slowly, rather than figures, which change constantly — that is why it can be trusted between reviews. It is not cloned per year and it will not gain a forecast. Where a city has enough supportable local data to be worth its own dated page, it gets one — Nashville's local market context and Knoxville's local market context are two of them. The cities without such a page do not have one because the data to support it has not been established, which is a gap this site states rather than fills. From here, the rest of the Tennessee guide covers the decisions the data feeds into.
