Rent and resale are moving in opposite directions in this ZIP. Zillow’s June 2026 ZORI was $2,028 per month, down 2.3% from a year earlier. In Redfin’s direct rolling-three-month ZIP resale observation, median sold price was $524,881, up 3.1% year over year. Annualized ZIP ZORI divided by that median sold price is 4.6%, a cross-source screening ratio only. It combines a broad asking-rent index with a resale median and does not describe a transaction, an individual property’s economics, or a property-level outcome. The price increase confirms firmer resale pricing over the reported comparison period, while rent cooling challenges any simple read-through from sales to asking rents.
Zillow ZORI is a typical observed asking-rent index blended across rental types, so it is not interchangeable with the matched Census measure. Current ZORI is 11.0% above the $1,828 ACS median gross rent. That ACS figure comes from the ACS 2024 five-year survey of occupied renter homes and includes selected utilities, whereas ZORI reflects asking-rent conditions rather than occupied-household payments. The five-digit label 37174 is both a Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. These source, timing, occupancy, and utility differences limit direct rent-level comparisons.
Exact same-month ZORI history through the stated endpoint shows a -2.31% annualized change over one year, -0.82% over three years, and 2.40% over five years. Recent direction therefore confirms the shorter three-year cooling path but breaks from the positive five-year path. Annualized monthly-return variability was 2.38%, maximum drawdown was -4.91%, and coverage was 99.3%, indicating a nearly complete historical record while still documenting meaningful downward movement. Transparent national discovery ranks among history-eligible ZIPs were 2,783 for momentum, 508 for stability, and 2,152 for the balanced measure, where lower rank is higher. These are backward-looking measurements, not forecasts or investment recommendations. The low reported variability and high coverage give more confidence in the consistency of the index record than in any single current rent snapshot as a universal property benchmark.
The resale observation provides direct ZIP-level liquidity signals, but only for for-sale transactions. Redfin reported 300 homes sold, a median marketing time of 58 days, and inventory of 469 homes, up 10.3% year over year. Months of supply stood at 4.7. The average sale-to-list relationship was 98.95%, while 15.1% of sales closed above list price. These are direct rolling-three-month resale observations, not rental transactions, lease comparables, or evidence of rental-property operations. Together with the rising sale-price measure, they challenge rather than confirm the cooling rent-history signal; inventory and sale signals do not resolve that cross-universe tension.
Bedroom planning requires a separate model rather than a relabeling of the all-types ZORI. Modelled monthly ZIP estimates, produced by scaling ZIP ZORI with the local HUD ladder, are $1,741 for a studio, $1,791 for a one-bedroom, $2,028 for a two-bedroom, $2,582 for a three-bedroom, and $3,037 for a four-bedroom. HUD FMR/SAFMR is an administrative bedroom-specific standard, not asking rent. The modelled two-bedroom estimate is 98.9% of the local HUD two-bedroom standard of $2,050 because the ZIP index is used as the scaling anchor. These are modelled estimates, never measured bedroom rents, and they cannot establish what a currently advertised unit commands.
The required-income screen is arithmetic: applying a 30% rent-to-income threshold to the current ZORI produces required annual income of $81,120. Relative to the ZCTA median household income of $105,181, the reported asking-rent-to-income screen is 23.1%. This is not advice and is not an applicant qualification rule; household income and a broad ZIP rent index do not identify an individual renter’s circumstances. ACS nevertheless reports that 2,067 of 5,061 occupied renter homes, or 40.8%, had gross-rent burdens at or above the threshold. That burden measure remains a five-year survey statistic for occupied renter homes, includes its own survey uncertainty, and cannot prove the burden associated with a particular available unit.
The ACS ZCTA housing base contains 20,269 housing units, with a 3.7% overall vacancy rate and a 25.9% renter share. Its structure mix is weighted toward single-family units rather than large multifamily buildings. Those aggregate stock and vacancy figures are not a count of currently rentable listings or evidence that a specific address is available. For wider context, Spring Hill city’s context rent is $2,030, Maury County’s context rent is $1,688, and the Nashville-Davidson--Murfreesboro--Franklin, TN metro context rent is $1,810; these are city, county, and metro values, respectively, rather than ZIP observations. The ZIP index is near the city context level and above the county and metro context values, but wider geographies should not replace the ZIP reading.
Source limits matter most where the figures appear to align. ZORI does not identify an available dwelling, its lease duration, its included utilities, or its physical condition; ACS does not provide current listing terms; HUD does not provide asking rents; and Redfin does not provide rental transactions. Concrete property-level checks are to match the advertised rent with the actual bedroom count, lease term, included utilities, condition, and current availability; to compare that bedroom count only with the modelled ladder rather than treating the ladder as a quote; and to keep recent resale evidence separate from rental evidence. Does the specific listing’s current asking rent and lease structure actually match the separate index and modelled scenario being used?
