Public housing data can help a buyer compare Atlantic Beach, Neptune Beach, Jacksonville Beach and Ponte Vedra Beach. The mistake is assuming that the highest city or ZIP number identifies the best market, the strongest investment, or the value of a particular home.
The top-tier ZHVI report shows August 2026 modeled values ranging from about $1.017 million in Jacksonville Beach to $1.850 million in Ponte Vedra Beach. The ZIP listing report shows median asking prices from $459,900 in 32233 to $1,297,500 in 32266. Those are not contradictory tables. They measure different things over different geographies.
City and ZIP are not interchangeable
Zillow's city ZHVI models the value of a defined part of the housing stock. Realtor.com's ZIP file summarizes listings offered during a month. A ZIP can cross or differ from a municipal boundary. The properties listed in one month can also be a very different mix from the full housing stock.
That is especially important on the coast. A month with more smaller inland homes listed can lower an asking-price median without changing the value of a renovated oceanfront property. A month with several large estates can move the median in the opposite direction.
Use a four-layer comparison
Layer 1: geography. Confirm whether the number describes a city, ZIP, county or metro. Ponte Vedra Beach is in Saint Johns County; Atlantic Beach, Neptune Beach and Jacksonville Beach are in Duval County.
Layer 2: metric. Separate modeled value, asking price, completed-sale price, active inventory and market time. Never substitute one for another.
Layer 3: property type. Review single-family and condo data separately. The property-type report shows that the direction and magnitude can differ.
Layer 4: property-specific evidence. Once an area is selected, narrow to similar location, condition, lot, water relationship, age, size and ownership structure.
What a careful comparison can answer
It can show whether selected city-level value indexes are moving together or diverging. It can show the current supply and asking-price context within selected ZIPs. It can identify where more property-level diligence is needed.
It cannot answer which community will appreciate most, whether a listed home is fairly priced, or whether one area is more desirable. Those conclusions require matched evidence and a buyer's own priorities.
The best comparison is not a leaderboard. It is a decision map. Public data narrows the field; property-specific records, inspections, insurance, association documents and comparable sales complete the decision.
