Cost of living in Tennessee: build a household housing budget

Most cost-of-living comparisons fail for the same reason: the two sides of the comparison were not built the same way. One includes property tax and the other does not. One is a metro average from a three-year survey and the other is a quote someone got last week. The numbers then differ by a lot, and the difference is entirely method.

This page is the method. It is the same sheet every city budget on this site uses, so the city pages can supply local inputs without re-arguing the structure. It publishes no figures of its own — the inputs are yours, and the sources are named so you can pull them at the address you actually care about.

1. Define the household before you define anything else

Write four things at the top of the sheet and keep them fixed for every place you compare:

• The household. How many people, how many vehicles, how many earners, and whether anyone has a recurring medical or care cost. A budget built for one household does not transfer to another.
• The tenure. Owning and renting are different cost structures, not different numbers. Decide which one you are pricing, and price the other separately if you genuinely have a choice.
• The year. Put a date on the sheet. Every input has a vintage and mixing vintages is how a comparison quietly becomes fiction.
• The comparison area. A specific address, a city, a county or a metro. These are four different geographies and they produce four different answers. Most published "cost of living" figures are metro-level, which means they average across places you would never consider.

2. Separate the purchase from the monthly run rate

Two budgets, not one. The purchase budget is a one-off: deposit, loan costs, inspections, the moving expense, and the settlement items that appear at closing — what Tennessee buyers and sellers actually pay at closing sets out which of those are which and who customarily pays them.

The run rate is what leaves the account every month once you live there. Confusing the two is the single most common budgeting error, because a purchase you can afford and a house you can hold are different tests.

3. Build the housing line from its six parts

The housing line is not "the mortgage". It is six separate items, and the last two are the ones people leave out.

1. Principal and interest, at a rate you have actually been quoted for your circumstances, not a headline rate.
2. Property tax. In Tennessee this is a local number with a fixed structure. The county assessor of property appraises the parcel; residential property is assessed at a percentage of that appraised value; the county commission and city governing bodies set the rate, expressed in dollars per hundred dollars of assessed value. Because the rate is set annually and varies by jurisdiction, look it up rather than estimate it — how to find the record, the jurisdiction and the current tax information for an address walks through it.
3. Insurance, quoted for the actual structure. Get a real quote: the building's age, roof, construction and flood exposure move this number far more than the postcode does.
4. Utilities, from the providers that serve that address. Ask the seller or landlord for twelve months of actual bills, which is a fact, rather than an average, which is not.
5. Association dues and any special assessment. If there is an association, the dues are only half the question; ask for the reserve study and the assessment history.
6. The maintenance reserve. The roof, the heating and cooling system, the water heater, the septic system if there is one. Each has a replacement cost and a remaining life. Put a monthly number against them, because the building will spend the money whether or not the sheet does.

4. Transport and everything else, counted consistently

Transport is usually the second largest line, and it is where a cheaper house further out gets expensive. Count the whole thing: vehicle payments, fuel at the real mileage your commute implies, insurance, maintenance, parking and tolls where they apply, and the cost of a second vehicle if the location requires one.

For the remaining categories — food, healthcare, childcare, personal, entertainment — use your own bank statements from the last twelve months as the baseline and adjust only what genuinely changes with the move. If you need a structure for the categories, the Bureau of Labor Statistics' Consumer Expenditure Surveys are the federal source for what households spend and on what. Note the vintage when you use them: the 2024 annual release was published in December 2025, so even the current federal data describes a year that has already finished.

One Tennessee-specific note for the tax line. The Department of Revenue's list of administered taxes contains no individual income tax, and the Hall income tax on interest and dividends is listed as archived, repealed for tax periods beginning on or after 1 January 2021. Sales tax has a state component and a local one that the Department says varies by county and city. So in a Tennessee budget the state-level income line is absent and the local property and sales lines carry more weight than they might elsewhere.

5. Compare cities on one sheet, with one set of assumptions

Put the candidate places in columns, not in separate documents. Same household, same tenure, same year, same six housing lines, same transport method. If one column has an input you cannot find, leave the cell empty and mark it — an empty cell is honest, and a guessed one contaminates the whole comparison.

The city budget pages supply the local inputs without repeating this method: the Nashville housing-based budget and the Memphis housing-based budget are two of them, and the fifteen-city comparison is where you pick which columns to fill.

6. Verify at the address, not at the state

Before you act on the sheet, take the three biggest lines to their sources. The tax line goes to the county assessor and the county trustee. The insurance line goes to an actual quote on that structure. The utility line goes to the providers that serve that parcel. Everything else can be estimated; those three should not be, and they are the ones large enough to change the answer.
