Quick Answer

Castroville is a small city in Medina County, about 25 driving miles west of downtown San Antonio on US-90. The original 1844 town sits on the Medina River, and two master-planned communities north of the highway, Alsatian Oaks and Flat Creek, have builders selling from about $390,000. All three are inside city limits and in Medina Valley ISD. The 2026 combined tax rate is $2.322494 per $100, and Flat Creek adds a yearly public improvement district payment. Lackland's Valley Hi Gate is about 15 to 16 miles east.

Key Takeaways
  • The old town, Alsatian Oaks and Flat Creek are all inside Castroville city limits, so your electric, water, sewer, gas and trash service all come from the City of Castroville. Each of the electric, water and gas deposits is $200.
  • Homes in the old town, Alsatian Oaks and Flat Creek pay the same eight taxing units for 2026, $2.322494 per $100. On a $450,000 home you live in, that comes to about $8,850 a year after the homestead exemptions.
  • Flat Creek's first 138 homesites are in a public improvement district (PID), a fixed yearly charge on the tax bill that repays the streets, drainage and water and sewer lines built for them: about $2,360 a year on a 50-foot homesite and about $2,890 on a 60-foot homesite, scheduled through 2056 unless it's paid off sooner. Alsatian Oaks has no PID.
  • Chesmar, Highland and Perry are building at Alsatian Oaks; David Weekley, Beazer, Toll Brothers and Perry are building at Flat Creek. Base prices run from about $390,000 to the $580,000s.
  • From Flat Creek and Alsatian Oaks it's about 15 driving miles to Lackland's Valley Hi Gate and about 16 from the old town. Camp Bullis is about 32 to 33 miles away.

Living There

What's it like to live
in Castroville?

US-90 works as Castroville's main street. The Walmart Supercenter, Haby's Alsatian Bakery, the gas stations and the turn onto FM 471 all sit along it. Off the highway, the town grid Henri Castro laid out in 1844 runs down to the Medina River, with houses from the 1850s on lots big enough to hold two of today's new-build homesites. North of the highway on the east side, Alsatian Oaks and Flat Creek are filling in with new streets of homes on lots 50 to 70 feet wide.

Plan on the car for a lot of the week. The closest H-E-B is at SH 211 and Potranco Road, about 11 miles east, and the base, the Medical Center and downtown are all highway drives. In return, a quiet Saturday can mean the city's 126-acre park on the river or a walk around the Landmark Inn's grounds a few blocks from City Hall. It's a town of about 3,400 people, up about 16% since 2020.

More about how Castroville started

Henri Castro held an 1842 colonization contract from the Republic of Texas. On September 3, 1844, he and 50 men crossed the Medina River near today's Landmark Inn, and on September 12 he founded Castroville, 25 miles west of San Antonio. Between 1842 and 1847 he brought more than 2,100 colonists to Texas, many from Alsace, which is where the town's nickname, the Little Alsace of Texas, comes from.

That history still shapes the old town's streets. The original grid is laid out in ranges and blocks, and you'll see those words in the legal description of an old-town home's appraisal record.

Is Castroville a good fit for you?

Castroville is a good fit if you want:

  • A choice between a brand-new home, with base prices from about $390,000 to the $580,000s, and an older house on a bigger lot in the historic town
  • One utility bill from the city for electric, water, sewer, gas and trash
  • Lackland as your installation, about 15 to 16 miles east on US-90, knowing Camp Bullis, Fort Sam Houston and Randolph are long drives from here
  • A river park, a state historic site and a small-town main street close to home, with bigger shopping a highway drive away
Neighborhoods

What are Castroville's neighborhoods,
and who is building there?

For a home search, Castroville comes in three parts: the old town around City Hall, and the two master-planned communities north of US-90 on the east side. All three are inside city limits. The rural homes and land around them share the 78009 ZIP code and the Castroville mailing address, but they can sit outside the city; there's more on those after the three profiles.

Section Where Homes Building now?
Old town Around City Hall, down to the Medina River Pre-owned, from the 1850s on No, pre-owned only
Alsatian Oaks US-90 at FM 471 New, from 2024 on Yes, from about $390,000
Flat Creek North of US-90, just east of Alsatian Oaks New, first homes in 2026 Yes, from about $408,000

The old town

The original grid runs from around City Hall on Fiorella Street down to the river and the Landmark Inn. Lots here often run a third of an acre or more, and an 1850s or 1860s house can share a block with an early-1900s frame house that has a recent addition. The appraisal district files many of them under its "Castroville Historic Homes" neighborhood. Historic properties can need the city's Historic Landmark Commission to sign off on exterior work, so ask about that before you plan a new porch or an addition.

Alsatian Oaks

A 435-acre community from Merit Commercial Real Estate where FM 471 meets US-90, next to the Walmart, planned for about 950 homes plus shops and offices along the highway. Homes in its first section date from 2024 on, on lots of about 6,500 square feet. The plan caps 50-foot homesites at 60% of the lots, and the rest are 60 and 70 feet wide. The amenities include a resort-style pool, a dog park, a community garden, pavilions, a playground and hike-and-bike trails, with a larger amenity center still planned, and the Alsatian Oaks Master Community Association runs the HOA. The city helps repay the community's streets and utility lines out of a share of the taxes the area already generates, so there's no PID here. Three builders are selling: Chesmar Homes from about $390,000; Highland Homes from the $390,000s for 50-foot lots and the $520,000s for 60-foot lots; and Perry Homes, whose 50-foot series starts in the $440,000s and 60-foot series in the $580,000s.

Flat Creek

About 255 acres north of US-90, directly east of Alsatian Oaks, planned for about 673 homes. The first phase has 138 homesites, 50 by 130 feet or 60 by 130 feet, and its first homes are finishing in 2026. The amenities are still to come: a resort-style pool, a community pavilion, playgrounds and walking trails, expected in 2028. HOA dues are $600 a year, billed $150 a quarter. Every first-phase homesite also pays the PID, a set yearly amount on top of property taxes, shown in the tax section below. On the 50-foot homesites, David Weekley Homes starts at about $408,000 and Beazer Homes at about $480,000; on the 60-foot homesites, Toll Brothers starts at about $530,000 and Perry Homes in the $580,000s.

Rural homes and land around Castroville

Past the city's edge, a 78009 address can be a house on a few acres or a tract of raw land. When the appraisal record has no City of Castroville line, the city tax drops off the bill, and the electric and water providers depend on the property; some rural places rely on a private water well and a septic system. Some land also carries an agricultural appraisal, which has its own rules if the land stops being used that way. The FAQ near the end of this page covers what to check before you make an offer on land.

What to know before you buy new here

The builder prices above are base prices: the lowest-priced plan a builder offers, on an ordinary homesite, with no upgrades, lot premium or incentive counted. Read them as the floor of each community, not the typical price of a finished house there. The 50- and 60-foot labels are the homesite's width, and the wider series cost more.

Both communities are early in their build-out. Flat Creek's plan has about 535 homes beyond the first 138, and all three Alsatian Oaks builders are still selling new homes. While they're still selling, a house you put on the market here within a few years would compete with brand-new homes a few streets over, and with the builders' incentives. Plan to hold it longer, or to rent it out after you move.

And call me before you walk into any builder's model home in Castroville. I come along to the model visits and negotiate with the builder for you, and the builder covers my commission. The full process is on my new construction page.

Drive Distances

How far is Castroville from Lackland,
the Medical Center and downtown?

About 15 driving miles from the two new communities to Lackland's Valley Hi Gate, which is open 24/7, and about 16 from the old town. Lackland is the only installation within 20 miles; the other three are 28 miles or more. The tables give rounded driving miles.

Property Taxes

What are property taxes
in Castroville?

For 2026, $2.322494 per $100 of taxable value inside Castroville city limits, the same in the old town, Alsatian Oaks and Flat Creek. Flat Creek's first-phase homesites also pay a fixed yearly assessment for the streets, drainage, water and sewer lines built for them. These homes are taxed by Medina County units, not Bexar County's, so San Antonio's rates and exemptions don't carry over.

  • Homestead: the house you own and occupy as your principal residence. Filing for the homestead exemption takes part of its value off the tax bill, unit by unit.
  • ESD (emergency services district): a fire and EMS district with its own tax line. In Castroville, Medina County ESD #1 is on the bill inside city limits too, at $0.100000.
  • PID (public improvement district): a district the city created to pay for the public improvements built for a subdivision. In Flat Creek it's the Castroville East Side Public Improvement District No. 2. Instead of a rate, each homesite carries a set assessment, paid in yearly installments that the city collects with your property taxes. Homestead exemptions don't reduce it. The old town and Alsatian Oaks have no PID.
  • TIRZ (tax increment reinvestment zone): a zone where part of the growth in property tax revenue goes toward the area's public improvements. Alsatian Oaks has one in place of a PID, and it shows on the bill at $0.000000, so it adds nothing to what you pay.

The table runs one example, a $450,000 house you live in, through each kind of Castroville tax bill.

Where the home is 2026 rate per $100 Where you'll see it Yearly tax, $450,000 homestead Per month
Inside Castroville city limits $2.322494 The old town and Alsatian Oaks About $8,850 About $735
Inside the city, Flat Creek PID, 50-foot homesite $2.322494, plus about $2,360 a year Flat Creek's first phase (David Weekley, Beazer) About $11,200 About $935
Inside the city, Flat Creek PID, 60-foot homesite $2.322494, plus about $2,890 a year Flat Creek's first phase (Toll Brothers, Perry) About $11,740 About $980

The PID part is a set dollar amount, so it stays the same whether the Flat Creek house costs $450,000 or $600,000; only the tax-rate part grows with the price. The monthly column is taxes only. Insurance and HOA dues are extra, on top of the mortgage and taxes; get an insurance quote early.

Those figures use the general homestead exemptions on a Castroville bill: $140,000 off the Medina Valley ISD value, $25,000 for ESD #1 and $3,000 for the county road tax. The City of Castroville, the county's general fund, the hospital district, the groundwater district and the Precinct 2 road tax show no general homestead exemption, and neither does the PID.

If you move out and keep the house as a rental, the homestead exemptions end once it's no longer your main home. The same $450,000 house in the old town or Alsatian Oaks would go from about $8,850 a year to about $10,450, and a Flat Creek house would add its PID installment on top of that.

More about the taxing units on a Castroville bill

The eight units for 2026: Medina Valley ISD $1.126600, City of Castroville $0.510000, Medina County $0.360400, Medina County Hospital District $0.100000, Medina County ESD #1 $0.100000, the County F.M. Road tax for farm-to-market and lateral roads $0.083000, the Medina County Precinct #2 special road tax $0.036400, and the Medina County Groundwater Conservation District $0.006094. Together they come to $2.322494. The city's rate dropped from $0.523300 last year, and Medina Valley ISD's from $1.152700.

To see the units on a specific home, look it up in Medina CAD's property search and read the taxing jurisdiction table. No "City of Castroville" line means the home sits outside the city, even with a Castroville mailing address.

On a new build, the first bill can cover the lot alone or a half-finished house, because the appraisal district values what's there on January 1. Budget for the year after, when the finished home is on the roll.

More about the Flat Creek PID

The city adopted the district's service and assessment plan in August 2026. Each of the first 138 homesites carries an assessment of $27,502.80 on a 50-foot lot or $33,789.16 on a 60-foot lot. The first installments, due by January 31, 2027, are $2,355.76 and $2,894.22, and the schedule keeps them close to that level each year through 2056. Paid on schedule, the 30 installments add up to about $70,800 on a 50-foot lot and about $86,900 on a 60-foot lot, interest and collection costs included. The amounts are updated each year when the city reviews the plan, and you can pay off the balance at any time instead.

Spread over the home values the plan assumed, the installment works out to about $0.45 per $100. The seller has to give you the PID notice before you sign a contract, and on a new build the builder's paperwork will include it.

Flat Creek's later phases, about 535 more homes, sit inside the same district. Their assessments haven't been set yet, so ask the builder for the figure on your homesite.

More about homestead filing and veteran exemptions

Once the house is your main home, send the homestead application (Form 50-114) to the Medina Central Appraisal District in Hondo.

When it kicks in depends on the house. On a resale, the seller's exemption usually stays on the bill for the year you buy; yours begins on January 1 of the following year, and the application is due by April 30 of that year. On a Flat Creek or Alsatian Oaks new build, no one held the exemption that year, so you can claim it for the months left in your closing year, provided you file before your closing's one-year mark.

After your first year with the exemption, a cap kicks in on the homestead's appraised value: it can't climb more than 10% a year unless you add on or improve the house. Owners 65 and older, and owners with a disability, get at least $60,000 more off the Medina Valley ISD value.

Disabled veterans can add an exemption on one property based on their rating (Form 50-135): $5,000 for 10% to 29%, $7,500 for 30% to 49%, $10,000 for 50% to 69%, and $12,000 for 70% to 100%. A veteran rated 100% disabled, or individually unemployable, who is paid 100% disability compensation pays no property tax on the homestead, and a surviving spouse who doesn't remarry keeps the exemption.

More about Castroville utilities and water rules

Inside city limits, the City of Castroville provides electric, water, sewer, natural gas and residential garbage service, all on one bill. You'll pay a $200 deposit each for electric, water and gas, and bring proof of ownership or a lease to open the account at City Hall, 1209 Fiorella Street. Flat Creek is inside the city's water and wastewater service area.

Castroville falls under the Edwards Aquifer Authority's critical period rules, and the city moved to Stage 3 water restrictions on September 1, 2026. Under Stage 3, sprinklers can run every other week on your assigned day, from 7 to 11 a.m. and 7 to 11 p.m., with the day set by the last digit of your address; the city posts the watering calendar. The stage moves up or down as the aquifer changes, so check the current one before you plan landscaping. If a new lawn comes with a new build, ask the builder how they handle it under the current stage.

Outside city limits, confirm the electric, water and sewer arrangements for that exact property before closing.

Before you tour Castroville

A brand-new house at Flat Creek and a 19th-century house near the river can be the same price and still be very different purchases. These are worth settling before the first showing.

  • The payment, with taxes and the PID in it. Your lender's approval is the most you can borrow; the payment you're comfortable with is your call. In Flat Creek, add the yearly PID installment to the tax estimate, about $2,360 to $2,890 for the first phase.
  • How much the school district weighs in your choice. The old town, Alsatian Oaks and Flat Creek are all in Medina Valley ISD, so the question is the campus: put the address into the district's zone map, and for a house in a section still being built, look at next year's zone too.
  • HOA rules that would stop you. Alsatian Oaks and Flat Creek both have an HOA. If a leasing limit would wreck your plan to rent the house out at your next PCS, or you need room for a boat or RV, or a fence or pet rule matters, let me know up front and I'll get the answer before the tour.
  • New, or old and full of character? Decide which matters more, a builder's warranty and an open floor plan, or a bigger lot and a house with a long history. Then list your must-haves and the things you'd walk away over.
  • The US-90 drive at your real hours. Drive from Castroville to your gate or office at the time you'd actually leave for work, then drive back during the evening rush.
  • Plans for an older house in the old town. If you'd change the outside of a historic property, ask the city's Community Development Department whether the Historic Landmark Commission needs to review it. Work it covers can be stopped until the commission approves.
Working With Tiffany

What working with me looks like
in Castroville

A Castroville search often comes down to a new build north of US-90 or an older house near the river. Plenty of my clients buy and close before they ever set foot in San Antonio, moving from places like California, Virginia, Guam, Germany and Korea. I'm Tiffany Reed, a REALTOR® at Real Broker who holds the Military Relocation Professional (MRP) certification. A Castroville purchase with me looks like this.

  • Older houses get extra homework. Before a resale tour, I get the seller's disclosure and whatever inspection reports already exist, and I look into how many years are on the roof, the air conditioning and heating, and the water heater. On a house built in the 1800s, that paper trail counts for a lot.
  • Inspections on every purchase. I recommend at least a general inspection and a sewer scope, a septic inspection instead on a home with septic, and an inspection at each stage on a new build. In my transactions, general inspections have cost $400 to $900, more for a bigger house, and a sewer scope about $99 to $150.
  • New builds start before the model home. Call me first. I go with you to the model visits, take on the negotiation over price, incentives, closing costs and upgrades, and follow the build as it goes up. I'm at every walkthrough with the inspection report in hand, and I go through it with you line by line. Already visited a builder on your own? I'll check whether I can still be added.
  • Tours you can take from far away. If you can't be here, I tour the homes with you on video so you can decide from wherever you are.
  • Thinking ahead to your next PCS. If you'd keep the house and rent it out after your next PCS, I pull rental comps for the homes on your list you're serious about, to show how a likely rent lines up with your monthly mortgage.
  • Financing and the finish line. For the loan, I'll connect you with lenders, VA lenders too. After that I write and negotiate the offer, coordinate the inspections, and do the final walkthrough with you before closing day.

What should I check before buying land around Castroville?

Start with the property's Medina CAD record, which shows its taxing units and whether the land has an agricultural appraisal. If it does and the land is later changed to a non-agricultural use, Texas charges a rollback tax for each of the previous three years that had the lower appraisal. Outside city limits, a property may rely on a private well and a septic system instead of city utilities, so ask about both, and plan on a septic inspection.
