Highland Farms is one of the few places left in Galveston County where the median lot is 93,240 square feet. That is 2.14 acres, on 75 single-family properties, roughly fifteen minutes from the I-45 corridor. For buyers who have been told that acreage in this county means driving to Alvin or Hitchcock, Highland Farms is the answer that sits inside Santa Fe ISD and keeps a Galveston County address. It is also a market where the listing photos tell you almost nothing, because what you are buying is the dirt, the water, and the wastewater, and none of those photograph well.
Acreage is a diligence purchase, not a house purchase
The house on an acreage tract is often the least consequential part of the transaction. Highland Farms has a median year built of 1999 and a median of 1,791 square feet, which means a modest house on a very large piece of land. The value sits in the land, so the diligence has to sit there too.
| Diligence item | Why it decides the deal | When to resolve it |
|---|---|---|
| Water source | Well versus public supply changes the appraisal and the loan | Before the option period opens |
| Wastewater | On-site septic requires a permit record and a functioning drain field | First week of the option period |
| Survey and fence lines | Occupied lines on large tracts rarely match the recorded plat | Order the survey day one, not at closing |
| Agricultural valuation | A tract carrying ag exemption triggers rollback tax if the use changes | Before you sign, not after |
| Floodplain and drainage | Galveston County coastal drainage affects buildable area | Alongside the survey |
| Deed restrictions | Large-tract restrictions govern livestock, outbuildings, and subdividing | Pull the recorded restrictions for the specific plat |
The rollback issue is the one that catches buyers. If a tract carries an agricultural valuation and you change the use after closing, Texas can assess rollback tax on the difference between the ag value and market value for prior years, plus interest. Ask for the current valuation status in writing and price the exposure before you make an offer, because the seller will not volunteer it.
What the Highland Farms numbers actually say
| Metric | Highland Farms | Santa Fe (citywide) |
|---|---|---|
| Single-family properties | 75 | n/a |
| Median lot size | 93,240 sq ft (2.14 acres) | n/a |
| Median square feet | 1,791 | n/a |
| Median year built | 1999 | n/a |
| Median market value | $319,510 | n/a |
| Median appraised value | $280,832 | n/a |
| Median appraised price per sq ft | $156.80 | n/a |
| Median sold price per sq ft | $150.00 | n/a |
| Neighborhood value range | $83K to $540K | n/a |
| Median sale price, September 2026 | n/a | $325,095 |
| Median days on market, September 2026 | n/a | 24 |
| Sale-to-list ratio, September 2026 | n/a | 97.2 percent |
| Homes sold, September 2026 | n/a | 49 |
| School district | Santa Fe ISD | Santa Fe ISD |
Read the $83K to $540K range carefully. On a 75-property subdivision, that spread is not noise. It is the difference between a raw or minimally improved tract and a finished home on a comparable lot. Three listings were active at the time of writing, at $579,000, $199,550, and $950,000, and two of those three are land rather than houses. That mix is normal here and it is exactly why a city-level median sale price tells you nothing useful about what you should pay for a specific Highland Farms tract.
Also note that the median sold price per square foot ($150.00) sits slightly below the appraised figure ($156.80). On acreage, per-square-foot pricing of the structure is close to meaningless. Price the land first, then price the improvements as a separate line.
The acreage factors most buyers never check
| Factor | What to verify | Where buyers get hurt |
|---|---|---|
| Lender type | Whether the loan treats the tract as residential or land | Conventional financing caps acreage and outbuilding value on some products |
| Appraisal comparables | Whether comps are genuinely acreage tracts | A 7,000 square foot lot comp will not support a 2-acre value |
| Access and easements | Recorded legal access, utility and pipeline easements | A pipeline easement can sterilize the part of the tract you wanted to build on |
| Road frontage | County-maintained versus private | Private road maintenance is your cost forever |
| Santa Fe zoning | The city has zoning, a zoning map, and a P and Z department | Assuming "country means no rules" is the expensive mistake |
| Tax stack | Galveston County at 0.3227 percent and Santa Fe ISD at 1.1014 percent, plus other units | The full rate varies by property and parcel |
| Electrical service | Distance from the pole to a planned structure | Service extension on a 2-acre tract is a four-figure to five-figure item |
That zoning point deserves emphasis because it is widely misunderstood. The City of Santa Fe does have zoning, a zoning map, and a planning and zoning function. If your plan involves a shop, a second dwelling, livestock, or a home business, confirm it against the actual ordinance for that parcel rather than against what a neighbor tells you they got away with.
The financing trap is worth one more paragraph, because it ends more acreage contracts in this county than inspections do. Many conventional loan products will finance the home and a limited amount of surrounding land, then treat the remainder as excess acreage that contributes little or nothing to the appraised value. On a 2.14 acre tract where most of your purchase price is the land, that gap becomes a cash requirement you did not plan for. The fix is to get the loan product settled before you write, not after the appraisal comes back short. Ask your lender directly how they handle acreage above the conforming threshold, whether they will give value to a detached shop or barn, and whether they require a well potability test and a septic inspection as a condition of funding. Lenders who do this routinely in Galveston and Brazoria counties answer those questions in one call. Lenders who do not will discover the problem on your timeline.
Tradeoffs: Highland Farms versus the alternatives
| Option | Upside | Trade-Off |
|---|---|---|
| Highland Farms acreage | 2.14 acre median lot, Santa Fe ISD, Galveston County address, established since the late 1990s | 75 properties means thin inventory, well and septic diligence, modest median home size at 1,791 square feet |
| A large suburban lot in a platted subdivision | Public water and sewer, conventional financing, predictable comps and resale | A quarter-acre is not acreage; no room for a shop, livestock, or real separation |
| Raw land in Highland Farms and building | Full control, and land listings here have ranged well below finished-home pricing | Construction financing, utility extension, septic permitting, and a timeline measured in quarters |
| Driving further out for cheaper acreage | More land per dollar | You leave Santa Fe ISD and add commute, and resale depth thins quickly |
The agent landscape for acreage, described plainly
| Type of brokerage | Typical strength | What to ask before you hire |
|---|---|---|
| Farm and ranch specialists | Land valuation, ag exemption, survey fluency | Do they close residential acreage in Galveston County specifically |
| Large residential franchises | Marketing reach and buyer volume | Have they handled well, septic, and rollback tax on a real file |
| Local independent brokerages | Plat-level and road-level knowledge | Bench depth if your agent is out mid-contract |
| Online and discount models | Low fee, fast listing input | Who negotiates the septic repair and the survey discrepancy |

Why The Mandie McMillan Team, Client for Life and not just "best agent"
Acreage rewards an agent who has actually worked the county. Mandie McMillan was born and raised in La Marque, the center of Galveston County, and has spent 50 years in this area and 26 years in the business. She knows which Santa Fe roads are county-maintained, which tracts carry drainage problems that do not show on a sunny Saturday, and which lenders will actually fund two acres with a shop on it.
In 2025 the team closed 75 sides and $22,127,458 in production volume, with Mandie personally closing 30 sides and $11,676,748. Across 6 producing agents, that is roughly 12.5 closed sides and $3.7 million per agent, which is depth over headcount. Mandie is a RE/MAX International Hall of Fame inductee and a repeat RE/MAX Chairman's Club and Platinum Club honoree, holds the SRS and CLHS designations, and served as 2017 President of the Women's Council of Realtors Bay Area chapter and 2018 Texas District Vice President.
Client for Life means she stays your advisor after closing, which matters on acreage more than anywhere, because the questions about easements, exemptions, and expansion keep coming for years.
