What we can and cannot show here
Population is 0 (below the 500 floor for ranking), so survey estimates are too noisy to rank reliably.
This is a coverage limit in the source data, not a judgement about the area. We publish scores for 20,132 of the 33,659 ZCTAs the Census Bureau defines; this one falls outside that set, so there is no score, grade, rank or trend to report and none is invented here.
Data vintage: ACS 2024 5-year.
Underwrite with these as starting points
No ACS median value is published for this area, so nothing is pre-filled; 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 94128
4 ZIP Code areas share a land boundary with 94128 in the official Census 2020 ZCTA map, ordered by shared-boundary length, not ZIP-number proximity or driving distance. 3 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 94128, and this list is ordered by border length, so it is not a ranking and no neighbour is called best.

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.
