ZIP 01915 presents an affordability tension before any bedroom or resale reading: Zillow's typical observed asking-rent index, which blends rental types, is $2,773 in June 2026. A simple 30% screen converts that monthly asking-rent index to $110,920 of annual gross income, above the matched ZCTA's $104,918 median household income. That screen is arithmetic only; it is neither advice nor an applicant qualification rule, and it does not establish a household's actual rent or eligibility. The five-digit label is both Zillow's ZIP market identifier and the matching Census ZCTA. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP.
The ACS record tells a materially different but not conflicting story. The matched ZCTA's ACS 2024 five-year survey places median gross rent at $1,770 for occupied renter homes, a measure that includes selected utilities and is not an asking-rent series. It records 6,761 renter-occupied homes and 3,484 households spending at least 30% of income on rent, or 51.5%. The current ZORI is 56.7% above the ACS median. Differences in timing, the survey's occupied-home universe, utility treatment, and the asking-rent construction prevent that gap from identifying a typical lease change or a burden level for any particular household.
Bedroom detail must retain that source distinction. HUD's local Fair Market Rent/Small Area Fair Market Rent ladder is an administrative, bedroom-specific standard rather than asking rent. It runs from $1,631 for a studio to $3,060 for four bedrooms, with a $2,311 two-bedroom standard. Applying that local HUD ladder proportionally to ZIP ZORI produces modelled monthly ZIP estimates of $1,957 for a studio, $2,113 for one bedroom, $2,773 for two bedrooms, $3,467 for three bedrooms, and $3,672 for four bedrooms. These are modelled estimates, never measured bedroom rents; they provide a transparent size pattern for the ZIP index but cannot substitute for unit-specific listings, HUD program determinations, or lease quotes.
The rent history puts today's reading in a high-variability setting rather than a straight-line trend. Through the stated June endpoint, exact same-month ZORI changes annualize to 4.34% over one year, 3.94% over three years, and 6.80% over five years. The latest annual pace therefore confirms the longer upward path but is slower than the five-year pace. Annualized monthly-return variability is 3.73%, maximum drawdown is -3.18%, and coverage is 98.9%. Transparent national discovery ranks among history-eligible ZIPs are 569 for momentum, 2,444 for stability, and 1,330 for the balanced measure, where lower ranks are higher. These are backward-looking measurements, not forecasts or investment recommendations; the variability means a reader should place less confidence in any single current rent snapshot than in a stable series.
Broader comparisons do not erase the direct ZIP distinction. The Beverly city-context asking-rent value nearly matches the ZIP index, while the Essex County context is $2,632 and the Boston-Cambridge-Newton, MA-NH metro context is $3,210; each is wider-area context rather than a substitute ZIP observation. The matched ZCTA has 17,302 housing units, including 9,214 single-family units and 2,526 units in large multifamily structures. Its 3.76% vacancy rate includes 130 units vacant for rent. Those survey aggregates describe stock and vacancy, not a claim that a particular unit is available, comparable, or affordable.
For-sale evidence supplies a separate resale-liquidity tension: the direct rolling-three-month ZIP resale observation reports a $776,824 median sold price, up 5.37% year over year, with 84 homes sold and a 20-day median marketing time. Inventory is 73 homes, 92.4% higher year over year, alongside 2.6 months of supply. The average sale-to-list relationship is 104.04%, and 67.14% of sales close above list. These are for-sale market observations, not rental transactions or rental comps. Annualized ZIP ZORI divided by median sold price is 4.28%, only a cross-source screening ratio—not a cap rate, net return, expected return, or property yield. Rising resale prices and strong sale-to-list signals sit beside expanding inventory, so the resale evidence aligns with the rent history's upward direction while challenging a simple, one-direction reading of resale conditions.
The evidence streams should be triangulated, not blended into a single rent claim. Zillow describes typical observed asking rent across rental types; ACS describes a five-year survey of occupied renter homes with selected utilities; HUD provides an administrative benchmark; and the city, county, and metro figures are context. History measures prior index movement, while Redfin tracks resale outcomes. None supplies a property's condition, exact bedroom configuration, utility package, concessions, lease length, tenant turnover, or transaction expenses. The ZCTA match is a geographic correspondence for survey comparison, but it does not convert the survey into a delivery ZIP, a current listing database, or a property appraisal.
Property-level checks are consequently necessary before applying this ZIP summary to one address. The record needed for a rental comparison is the current advertised rent, bedroom count, unit type, included utilities, concessions, availability date, and lease terms; the record needed for a resale comparison is the actual sale price, list history, property condition, and whether the observed home resembles the subject. Confirm the geography used by each record and keep survey, administrative, asking-rent, and resale evidence in their separate universes. The unresolved question is not whether a ZIP average decides a unit's terms, but whether the particular unit's current terms and characteristics genuinely resemble the measurement being used.
