The Real Cost of Owning Property in Rockport-Fulton, TX

Purchase Price: Three Different Numbers, Genuinely

Home prices in Rockport show real volatility depending on which statistic and which month you look at, and this page won't pretend to reconcile them into one clean figure. Zillow's typical home value (its smoothed ZHVI statistic) for Rockport was reported at $263,460, up 14.2% year-over-year. A separate average-home-value figure covering roughly the same period was reported at $312,318, down 2.7% year-over-year -- a different metric entirely, and one moving in the opposite direction. Meanwhile, the median sale price across all home types was reported at $384,265 in May 2026, up 4.0% year-over-year, with the median list (asking) price that same month around $399,000. Those are three genuinely different numbers from different sources measuring different things -- a smoothed value index, a simple average, and an actual transaction median -- and none of them should be treated as this market's single settled price. What they do show consistently is a market still appreciating, several years after Harvey, with real spread between waterfront/canal-front property (Key Allegro and similar bay-and-canal communities command a premium for direct water access and dock potential) and inland Live Oak Peninsula lots further from the water. Get current, address-specific comparables from a local agent rather than anchoring to any one of these headline figures.

Aransas County's median household income has also been reported two different ways in recent snapshots -- $58,168 per 2022 ACS data and $63,434 per a 2023 estimate -- and Aransas County's total population (23,830 at the 2020 Census) is small enough that these figures can move meaningfully year to year. What that means practically: this is not a market with the deep, liquid transaction volume of a major metro, and pricing statistics here will naturally show more month-to-month noise than a bigger city's numbers would. Budget with a range, not a point estimate, and expect a local agent's read on a specific block or canal to matter more than any citywide average.

Property Tax: A Real, Cited Range, Not a Refusal to Answer

Aransas County's effective property tax rate has been reported at approximately 1.09% (median effective rate, per Ownwell's aggregated property-record analysis) and, by a separate collection-rate calculation, around 1.29% of assessed fair market value. That's a real, source-attributed range worth stating plainly rather than hedging away from: on today's roughly $384,265 median sale price, an effective rate in that 1.09%-1.29% band implies an annual property tax bill somewhere around $4,190-$4,955 -- a genuinely material cost, and higher than what a comparable-priced home would carry in most non-Texas coastal states, precisely because Texas has no income tax to offset it. A separately cited median Aransas County tax bill of $1,849 appears to be calculated against an older, lower median home value baseline (around $129,900) reported by the same source, so treat that $1,849 figure as historical/baseline rather than representative of what a buyer at today's prices would actually owe. Texas voters approved Proposition 13 in November 2025, raising the school-district homestead exemption from $100,000 to $140,000 for all homeowners, plus a separate measure, Proposition 11, adding a further $60,000 exemption for owners 65 and older or disabled -- a combined $200,000 exemption for a qualifying senior or disabled owner -- both for the 2025 tax year onward -- a real, current reduction in taxable value for anyone making the property their genuine primary residence, though it only applies to the school-district portion of the bill and only to a homesteaded primary residence, not a second home or rental. This market's property-tax subpage goes deeper on the mechanics; the specific combined city/county/school millage rate for a given Rockport or Fulton address was not independently confirmed in the research behind this page, since the City of Rockport's own tax-rate notice could not be fetched directly this pass -- pull the exact current combined rate for a specific parcel from the Aransas County Appraisal District (aransascad.org) or the Aransas County Tax Office before finalizing a budget.

Insurance: TWIA, Flood, and the Real Cost of Harvey's Legacy

Insurance here is not a routine line item -- it's a structurally different cost than a buyer moving from an inland market will expect, and Harvey is the reason. Aransas County is one of 14 Texas counties designated first-tier coastal, making Texas Windstorm Insurance Association (TWIA) coverage available where standard private windstorm coverage may be thin or unavailable; any structure built, altered, remodeled, or added to since January 1, 1988 needs a WPI-8 Certificate of Compliance (issued through the Texas Department of Insurance's Windstorm Inspection Program since June 2020) to be TWIA-eligible at all. Flood insurance is a second, separate cost: First Street Foundation's modeling puts 77.7%-77.8% of Rockport properties (6,291 of them) at some level of flood risk over a 30-year horizon, and any property in a FEMA-mapped Special Flood Hazard Area (Zone AE or VE) with a federally backed mortgage is legally required to carry flood insurance, not just advised to. No specific current TWIA premium, standard homeowners premium, or NFIP flood-insurance premium figure for a Rockport or Fulton property was confirmed in the research behind this page -- these vary too much by construction date, elevation, distance from water, and roof/wind-mitigation features to state a representative number honestly. Get written, current quotes from a Texas-licensed agent for the specific property before budgeting; this market's coastal-insurance and storm-prep-costs subpages go deeper on both.

Ongoing Costs: HOA, Docks, and Salt-Air Maintenance

Homeowners association fees are not a market-wide constant here the way they are in a planned resort community -- Key Allegro and some other canal-front and bayfront communities on the peninsula have their own associations and dues, but plenty of Rockport-Fulton housing stock, especially older inland lots, carries no HOA at all. Confirm HOA status, dues, and any dock or canal-maintenance assessments directly with the specific community or a local agent rather than assuming a figure. For anyone buying a property with an existing private dock or pier -- a real, common feature on Aransas Bay, Copano Bay, and Key Allegro's canals -- ongoing maintenance is a genuine, recurring cost: saltwater and occasional storm exposure age wood, hardware, and boat lifts faster than freshwater use would, though this research did not find a representative annual maintenance-cost figure to cite. This market's dock-pier-guide subpage covers the permitting side of that in detail. More broadly, salt air and humidity along this stretch of coast are a real, if unquantified in this research, driver of higher-than-inland maintenance costs on roofing, exterior paint, HVAC equipment, and metal fixtures -- a standard coastal-Texas reality worth budgeting a maintenance reserve for, even without a specific dollar figure to cite here.

What This Means for a Real Budget

Put together, a realistic Rockport-Fulton ownership budget has four real, sourced pieces and at least two honest gaps. The sourced pieces: a purchase price that, depending on the property and the month, could reasonably be read anywhere from the high-$200,000s (Zillow's typical value) to the high-$300,000s or more (current median sale price); an annual property tax bill in the neighborhood of $4,200-$5,000 on a median-priced home at the county's reported effective rate, reducible for a genuine primary residence via the new $140,000 school-district homestead exemption (or $200,000 combined for owners 65+ or disabled, via Propositions 13 and 11); mandatory or near-mandatory flood insurance given that roughly three-quarters of Rockport properties carry some 30-year flood risk per First Street; and TWIA-eligible windstorm coverage requiring a current WPI-8 compliance certificate. The honest gaps: no confirmed combined city/county/school millage rate for a specific address, no confirmed representative insurance premium figures, and no confirmed dock or salt-air maintenance cost baseline. None of that is a reason to avoid this market -- Texas's lack of state income tax is a real, structural advantage this page states plainly -- but a serious buyer should build a written, current, address-specific budget with a local agent, the Aransas County Appraisal District, and a Texas-licensed insurance agent before making an offer, rather than relying on any of the ranges cited here as a final number.
