ZIP 53718 enters June 2026 with a cross-universe mismatch that should be kept separate rather than smoothed over. Zillow’s ZIP-level ZORI is $1,690 per month, up 4.1% from the same month a year earlier, while Redfin’s direct ZIP resale median price rose more slowly. ZORI is a typical observed asking-rent index blended across rental types, not a transaction rent or a bedroom-specific quote. Annualized ZORI divided by the Redfin median sold price produces a 4.7% cross-source screening ratio. That arithmetic is not a cap rate, net return, expected return, property yield, or evidence of economics for an individual home. The gap requires distinct rental and for-sale readings, not a blended conclusion.
The five-digit label is both Zillow’s ZIP market identifier and this analysis’s matched Census ZCTA. The ACS 2024 five-year median gross rent for that ZCTA is $1,696. This five-year survey covers occupied renter homes and includes selected utilities, so its near match to ZORI does not make those measures interchangeable. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Wider context needs named scope: the City of Madison context rent is $1,656, Dane County’s context rent is $1,682, and the Madison, WI metro context rent is $1,676. Each comparator is wider than the ZIP and serves as context rather than substitute rental evidence.
HUD’s FY2026 local FMR/SAFMR ladder is an administrative, bedroom-specific standard rather than asking rent. Its two-bedroom standard is $1,182. Scaling ZIP ZORI across the local HUD ladder yields monthly modelled estimates of $1,222 for a studio, $1,288 for a one-bedroom, $1,690 for a two-bedroom, $2,274 for a three-bedroom, and $2,687 for a four-bedroom. These are modelled estimates, never measured bedroom rents. The two-bedroom alignment with the overall ZORI follows the model construction, while ZORI itself remains blended across rental types. Neither the HUD standard nor the scaled ladder establishes what any currently listed unit is asking.
Affordability signals answer a different question from the rent series. Applying the 30% screen arithmetically to a $1,690 monthly asking-rent index produces $67,600 in annual required income; it is not advice and not an applicant qualification rule. The ACS ZCTA median household income is $102,843. Among 3,619 surveyed renter-occupied homes, 1,140, or 31.5%, reported gross-rent burdens at or above that screen. This survey measure includes selected utilities and identifies a share of occupied renter homes, not the payment, burden, or eligibility of a particular household or unit.
ACS housing-stock evidence describes the ZCTA rather than a live inventory feed. It estimates 8,535 housing units and 454 vacant units, a 5.3% vacancy rate. Of the occupied stock, 3,619 homes are renter occupied, representing a 44.8% renter share; the balance is owner occupied. The stock spans single-family and large multifamily structures, and 174 vacant units are classified for rent. These classifications do not say when units become available, what they ask, or whether a vacancy applies to a particular property. Vacancy therefore cannot prove availability or conditions for any one unit.
The backward-looking Zillow history supplies a more measured reading of the rent path. Exact same-month annualized ZORI changes are 4.1% over one year, 3.1% over three years, and 5.3% over five years. Recent direction thus confirms growth relative to the three-year pace but does not fully match the stronger five-year path. The series has 100% coverage at the stated endpoint. Annualized monthly-return variability is 2.2%, which limits how much confidence should rest on a single current rent snapshot even within a fully covered history. Separately, the maximum drawdown from a prior peak was 1.5%. Transparent national discovery ranks among history-eligible ZIPs are 760 for momentum, 271 for stability, and 185 for the balanced measure; lower ranks are stronger. These backward-looking measurements are neither forecasts nor investment recommendations.
Redfin’s direct rolling-three-month ZIP resale observation ending June 30, 2026 has a $429,903 median sold price, up 1.8% from a year earlier. It records 92 homes sold, a 42-day median marketing time, 70 homes of inventory, and 2.3 months of supply. The average sale-to-list result is 100.94%, and 39.4% of sales closed above list. These are for-sale/resale observations, not rental transactions, rental comparables, or property economics. They challenge any assumption that the faster current ZORI increase automatically translates into equally fast resale-price growth, even as the ZIP’s resale record shows direct sale activity and above-list outcomes. The evidence sets a tension across universes rather than confirming a common transaction trend.
All of the figures are market-level indicators with source-specific limits: ZORI is a typical asking-rent index, ACS represents surveyed occupied renter homes, HUD is an administrative standard, and Redfin measures direct ZIP resale outcomes. ACS estimates also have published margins of error, and neither ACS vacancy nor burden can be assigned to an individual unit or tenant. Concrete property-level checks must establish the actual bedroom count and unit type, current asking rent, included utilities, lease terms, size and condition, and relevant sale-listing history before any ZIP statistic is applied to a property. The unresolved question is whether those property facts align with the modelled ladder and the separate rental and resale screens without treating either as a guarantee.
