Onslow County delivers one of the most favorable tax rates in coastal NC. Most Holly Ridge mainland properties sit in Zone X with no flood insurance requirement. Here is the complete carrying cost picture.
Holly Ridge's carrying cost structure is among the most straightforward on this platform. Onslow County's tax rate is low. Most Holly Ridge residential properties are in Zone X, meaning no mandatory flood insurance. Wind insurance is required as a coastal county but runs lower than barrier island positions at comparable values. The primary variable that buyers sometimes miss is subdivision HOA fees, which vary widely across Holly Ridge's active development areas and are not always clearly disclosed in listing presentations.
Onslow County's combined property tax rate for Holly Ridge properties runs approximately $0.44-$0.50 per $100 of assessed value as of 2025, including the county rate and the Holly Ridge town overlay. This is among the lowest coastal county rates in North Carolina and a genuine structural advantage that compounds meaningfully over a long hold period.

On a $700K Holly Ridge property versus a comparable $700K property across the bridge in Pender County (Surf City), the annual tax savings is approximately $840. Over a 10-year hold that is $8,400 in tax alone, before any insurance or HOA differential is considered.
Onslow County is in North Carolina's coastal wind insurance zone. Separate wind coverage from homeowners insurance is required. Because Holly Ridge is a mainland community rather than a barrier island community, wind insurance rates run meaningfully lower than comparable Surf City or North Topsail Beach properties:
New construction in Holly Ridge's active phases typically qualifies for wind mitigation credits from the start, which is one of the carrying cost advantages of buying new over resale in the corridor.
This is Holly Ridge's most significant carrying cost advantage over the Topsail Island barrier island communities. Most Holly Ridge residential properties, particularly in the newer subdivision areas, carry FEMA Zone X designations. Zone X means no mandatory flood insurance for federally backed mortgages. Buyers can elect optional coverage at $400-$800 per year or carry none at all.
The exceptions are Stump Sound-adjacent and lower-lying creek properties on Holly Ridge's eastern edge, where Zone AE designations appear in some positions. Verify the specific flood zone for any address before modeling carrying costs. Do not assume Zone X because the property is in Holly Ridge; confirm it.
Holly Ridge's active new construction subdivisions have varying HOA structures that are not always clearly communicated in listing presentations. Some phases have no HOA. Some have modest community maintenance fees of $500-$1,500 per year. Some have more comprehensive HOA structures with amenity access fees. Before modeling any Holly Ridge subdivision purchase, request and review:

The same $700K that buys a Zone X subdivision home in Holly Ridge with an estimated $19,000 annual carrying cost would buy a Surf City oceanside or sound-adjacent property carrying Zone AE flood insurance, higher wind rates for the barrier island position, and Pender County's higher tax rate. The all-in Surf City annual cost on a comparable value property would typically run $28,000-$36,000. Over 10 years that gap is $90,000-$170,000 in cumulative carrying costs before any appreciation or equity difference is considered.
That is not an argument for Holly Ridge over Surf City in every case. Direct ocean access and island living have genuine value that does not show up in a carrying cost comparison. But it is an argument for running the full numbers honestly before concluding the Surf City purchase is the right trade for your specific goals.
