It stays searchable; available government estimates remain below (data tier: Profile).

Each point is one ACS 5-year estimate on the same 2020-Census ZCTA boundary. Adjacent releases overlap, so the release-to-release differences are not independent annual market movement.

Missing releases remain gaps and are never interpolated. Home value is owner-reported; gross rent describes renter housing stock; population is a ZCTA estimate. Dollar figures are nominal.
Measured market data
Measured observations for this ZIP Code, published beside the government survey figures above rather than replacing them. They measure different things and will legitimately disagree; the reconciliation below states on which axis, one axis at a time, instead of leaving a reader to guess. ZORI does not correct the ACS rent; neither is a better version of the other. Monthly series, revised in recent months, observed 2026-08, not live.
| Figure | ACS survey estimate | Zillow measured index |
|---|---|---|
| Typical home value | $988,300±$52,000, the Census Bureau’s published 90% margin of error | $1,429,619no published margin of error |
| Methodology typical home value | The median of what owners themselves estimate their own home to be worth, across owner-occupied homes only. | A smoothed index of the typical value of homes in the middle tier (35th to 65th percentile) of the local stock, whether or not they sold. |
| Source | U.S. Census Bureau, American Community Survey 5-year estimates. | Zillow Economic Research public research data. |
| Vintage | ACS 2024 5-year: one estimate pooled over 2020–2024. Restated once a year, not monthly, and adjacent releases overlap. | Monthly series, observed 2026-08 and revised in recent months. Not live. |
| Geography | 2020 Census ZIP Code Tabulation Area 11577. | USPS ZIP code 11577: a related, but not identical, area. |
The index for typical home value is $441,319 higher than the survey estimate, whose own 90% margin of error is ±$52,000: the two are separated by more than survey sampling error alone accounts for. A gap of either size is expected when the source, vintage, methodology and geography all differ, and is not evidence that either figure is wrong. Neither figure corrects the other, and no margin of error is implied for the index, which publishes none.

Underwrite with these as starting points
Opening a calculator pre-loads the ACS median owner value and median gross rent as a survey-level starting point; every calculator input is editable. Owner-occupied median value and renter median gross rent describe different housing stock: the median-valued home is not the typical rental, so this is a screen, not a listing, appraisal, asking rent, cap rate, or forecast. Bring your own entry price and rent.
ZIP Codes bordering 11577
6 ZIP Code areas share a land boundary with 11577 in the official Census 2020 ZCTA map, ordered by shared-boundary length, not ZIP-number proximity or driving distance. 4 of them are in CE’s ranked set and are listed below, each with its own Rental Investor ZIP Score, grade and national rank, read from the same published dataset as this page. The rest are counted here and searchable from the ZIP Code explorer. A neighbour’s score is a score for that area, never for 11577, and this list is ordered by border length, so it is not a ranking and no neighbour is called best.
Evidence, sources & limitations
Official geography: Roslyn Heights CDP, Nassau County. Analytical entity: the U.S. Census ZIP Code Tabulation Area (ZCTA) 11577, an approximation of the USPS ZIP delivery area, not its exact route boundaries. Model z3-measured-v1; data ACS 2024 5-year.
This ZIP Code area is primarily in Nassau County, overlapping Roslyn Heights and other places, by land-area overlap from the official Census 2020 ZCTA relationship files (not population or address share).

Class: survey = ACS estimate (with margin of error); derived = computed from ACS. The survey gross-rent yield is a proxy (renter gross rent vs owner-occupied value, different housing stock; ACS top-codes very high values/rents) and is not a cap rate. Subscores are national percentiles among data-eligible areas; ranks are competition-ranked with deterministic ties. No vendor, listing, parcel, or school data. Not investment advice.
