The sharpest measured tension in 10031 is that ZIP asking-rent momentum and ZIP resale pricing point in different directions. Zillow ZORI for June 2026 is $3,128 per month, up 6.8% from the same month a year earlier, while Redfin’s direct ZIP resale observation reports a $624,859 median sold price, down 10.7% year over year. Its nine completed sales, 100 median days on market, and 17.3 months of supply describe the for-sale market rather than rental transactions. Annualized ZIP ZORI divided by median sold price produces a 6.01% cross-source screening ratio only; it joins unlike rent-index and resale-price sources and does not describe an individual property’s economics.
The rent history supports a positive longer path, although it is not a forecast. The one-year same-month annualized ZORI change is 6.8%, above the three-year measure of 5.3% but below the five-year measure of 7.1%. Recent direction therefore confirms sustained rent growth rather than breaking from it, while falling short of the full five-year pace. Monthly rent changes annualize to 2.7% variability, which supports somewhat more confidence in a current index snapshot than a highly erratic series would. Separately, the historical maximum drawdown reached 11.6%, showing that even this broadly rising series has experienced meaningful retreats. The history has 138 observations and 100% coverage. National discovery ranks among history-eligible ZIPs are 157 for momentum, 1,061 for stability, and 138 for the balanced measure, where lower rank is higher; these are transparent backward-looking discovery tools, not ratings or predictions.
Source scope explains why the current asking-rent index should not be treated as the same thing as household rent data. The five-digit 10031 label is both a Zillow ZIP market identifier and a matched Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Zillow ZORI is a typical observed asking-rent index blended across rental types, whereas the ACS 2024 five-year survey places median gross rent at $1,769, with a $86 margin of error, for occupied renter homes and including selected utilities. The ZORI level is therefore 1.77 times that survey median, not a like-for-like increase in a single unit’s rent. For wider context rather than ZIP substitution, City of New York asking-rent context is $4,133, New York County asking-rent context is $4,833, and New York-Newark-Jersey City, NY-NJ-PA metro asking-rent context is $3,573.
The bedroom figures are useful as a consistent modelled ladder, not as measured bedroom rents in 10031. Scaling ZIP ZORI with the local HUD ladder yields modelled monthly estimates of $2,269 for a studio, $2,632 for one bedroom, $3,128 for two bedrooms, $3,832 for three bedrooms, and $4,415 for four bedrooms. The corresponding local HUD two-bedroom FMR/SAFMR standard is $2,616, placing the modelled two-bedroom estimate 19.6% higher. HUD FMR/SAFMR is an administrative, bedroom-specific standard rather than asking rent, and the modelled ladder inherits the blended composition of ZORI. It cannot establish what a particular advertised unit, lease renewal, or building actually commands.
The affordability screen sharpens the difference between current asking rent and the resident survey. Applying the 30% arithmetic screen to annualized ZORI produces required household income of $125,120, compared with a ZCTA median household income of $65,283. Annualized current ZORI equals 57.5% of that median income before accounting for differences in household composition, unit size, utilities, or the timing of the datasets. This is an arithmetic comparison, not advice and not an applicant qualification rule. Separately, the ACS estimates that 49.6% of renter households pay at least 30% of income toward gross rent. That burden figure is a five-year survey statistic for occupied renter homes; it is not proof that any particular renter or available apartment has that payment burden.
The ACS housing profile indicates a renter-dominant stock rather than a predominantly owner-occupied ZIP. Of 24,305 housing units, the renter share is 85.9%. The estimated vacancy rate is 7.4%, and 674 units are classified as vacant for rent. These figures identify broad stock and vacancy conditions across the matched ZCTA survey universe, not a count of units that can be leased immediately at the Zillow index level. The structure data are also concentrated in large multifamily buildings, which is relevant to interpreting a blended asking-rent index but does not establish unit condition, turnover, concessions, lease terms, or bedroom mix for a specific property.
Redfin adds a separate liquidity check to the rent picture. Its direct rolling-three-month ZIP resale evidence shows 53 homes of inventory, down 7.6% from a year earlier, alongside the previously reported nine sales and long marketing time. The average sale-to-list ratio was 99.89%, while 22.2% of sold homes closed above list price. Those measures belong solely to the resale universe: they do not create rental comparables or verify a landlord’s asking rent. The resale evidence challenges a simple reading of rent strength because the ZORI gain occurred alongside a lower median sold price and ample months of supply. At the same time, the near-list average shows that the limited set of completed sales was not uniformly transacting at steep discounts to list.
Several limits remain material before applying these ZIP measurements to an address. Zillow reports an index rather than executed lease terms; ACS is a multi-year ZCTA survey of occupied homes; HUD provides administrative standards; and Redfin describes a limited rolling resale sample. None identifies building condition, legal bedroom count, concessions, utilities, fees, lease duration, or a unit’s actual availability. A property-level file therefore needs the current advertised effective rent, included utilities, bedroom layout, listing date, comparable recent listings or leases where available, and the specific property’s sale and listing history. The central check is whether those address-level facts align with the ZIP’s rising asking-rent history while the separate local resale evidence remains slower and more supply-heavy.
