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 ACS median home value is what owners report their home is worth in a 5-year survey, while ZHVI is a monthly index of typical home value; ACS median gross rent is what sitting tenants pay including utilities, while ZORI is an index of asking rent on newly listed units. ZORI does not correct the ACS rent; neither is a better version of the other. Monthly series, revised in recent months, observed 2026-07, not live.

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.

Evidence, sources & limitations
Official geography: Great Falls CDP, Fairfax County. Analytical entity: the U.S. Census ZIP Code Tabulation Area (ZCTA) 22066, an approximation of the USPS ZIP delivery area, not its exact route boundaries. Model z2-gov-subscores-v1; data ACS 2024 5-year.
This ZIP Code area is primarily in Fairfax County (spans multiple counties), overlapping Great Falls 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.
