Cooling rather than broad acceleration is the central tension in ZIP 38637. Zillow’s June reading places ZORI, a typical observed asking-rent index blended across rental types, at $1,571 per month. The direct Zillow ZIP history’s exact same-month backward-looking change is 0.56% over one year, versus annualized 2.79% over three years and 4.04% over five years. Thus, recent direction breaks from, rather than confirms, the longer growth path. The monthly-return series has 3.41% annualized variability and a -3.44% maximum drawdown. It has 100% coverage across 64 observations, which supports a complete historical read, but cooling means one current snapshot deserves less weight as a summary of the multi-year path. Transparent national discovery ranks are 1,698 for momentum, 2,146 for stability, and 2,208 for balance, where a lower rank is higher. These are measurements, not forecasts or investment recommendations.
Resale does not show an identical near-term signal. In Redfin’s direct rolling-three-month ZIP for-sale observation, the median sold price was $219,850, up 2.26% year over year; 61 homes sold with a median 17 days on market. The report records 51 inventory homes and 2.5 months of supply. Average sale-to-list was 97.93%, 22.05% of sales were above list, and 50.1% went off market within two weeks. This is a for-sale/resale record, not rental transactions or rental comps. The 8.57% annualized-ZORI-to-median-price figure is only a cross-source screening ratio. Price appreciation and short marketing time challenge any simple reading of rental cooling as uniformly soft housing conditions, while neither establishes property economics.
Source boundaries explain some of the apparent gap. The Census ZCTA matched to ZIP 38637 is a statistical area, not identical to a USPS delivery ZIP. Its ACS 2024 five-year survey covers occupied renter homes rather than advertised units and reports $1,435 median gross rent, including selected utilities. That survey measure is 9.5% below the current asking-rent index. ZORI is instead a ZIP-level typical observed asking-rent index blended across rental types, so it should not be treated as a median leased rent or combined mechanically with ACS. Different survey and observation frames, utility treatment, and timing make the difference descriptive rather than a measure of change in any one home.
Affordability creates the sharper rental-side tension. At a 30% rent-to-income arithmetic screen, annual income of $62,840 corresponds to the current monthly ZORI, against a reported ZCTA median household income of $53,311; the annualized asking-rent-to-income calculation is 35.4%. This screen is arithmetic only, not advice and not an applicant qualification rule. Separately, ACS estimates 2,277 of 4,218 renter households, or 54.0%, as burdened at that threshold; its 90% margin of error is ±536 households for the burdened count. Burden is a household survey outcome, not proof that a particular available or prospective unit is unaffordable.
The supplied local HUD ladder provides a bedroom-shaped comparison, but it is an administrative FMR/SAFMR standard rather than asking rent. Scaling ZIP ZORI by that ladder produces modelled monthly estimates—not measured bedroom rents—of $1,313 for a studio, $1,425 for one bedroom, $1,571 for two bedrooms, $2,076 for three bedrooms, and $2,413 for four bedrooms. The estimates preserve the local HUD bedroom relationships while anchoring the level to the ZIP asking-rent index. They cannot establish the rent for a unit with any bedroom count, nor can the HUD standard be read as an advertised price, lease transaction, or utility-inclusive market median.
Aggregate housing composition supplies a different constraint on interpretation. The matched ZCTA contains 10,987 housing units, with an 8.3% vacancy rate and a 41.9% renter share among occupied homes. Its stock includes 8,403 single-family units and 353 large-multifamily units, while 526 vacant units are classified for rent. Those are area-level ACS counts and classifications, not a count of listings at a given moment. In particular, the vacant-for-rent figure cannot prove that a specific home is available, habitable, similarly priced, or suited to a renter’s terms; it only frames the aggregate stock and vacancy backdrop.
Context values widen the lens but do not replace direct ZIP evidence: the City of Horn Lake context rent is $1,571, the DeSoto County context rent is $1,676, and the Memphis, TN-MS-AR metro context rent is $1,435. Each is a contextual city, county, or metro measure rather than a direct ZIP observation or rental comp. County context also has a lower renter share and vacancy rate than the ZIP/ZCTA figures, while metro context reports a lower rent-to-income screen. Those comparisons reinforce that broader geographies can point in differing directions without resolving the rent, burden, or availability of an individual property.
The limiting question is how closely a specific property matches these aggregate measures. ZORI blends rental types; ACS describes surveyed occupied renter homes with selected utilities; HUD is an administrative standard; and Redfin captures rolling resale activity. Property-level facts that can alter interpretation include the advertised rent, bedroom count, property type, included utilities, lease term, concessions, current availability, and the timing and characteristics of any sale comparison. None of the series identifies a unit’s condition or transaction terms. The evidence therefore supports a bounded comparison of cooling asks, surveyed burden, modelled bedroom relationships, and resale liquidity—not a forecast. Does the specific listing’s rent and terms actually fit the source definitions behind this snapshot?
","findings":[{"body":"Zillow’s ZIP asking-rent index is nearly flat on the latest same-month comparison after stronger three- and five-year growth.
