One-Acre Land Prices in San Antonio, Texas

One-acre lots in San Antonio currently list between $40,000 and $250,000, with location and infrastructure access creating most of that range. Properties inside Loop 1604 on the northeast side near Stone Oak and the 281 corridor command the highest prices per acre. Acreage along the southwest and far west corridors near US-90 typically falls between $50,000 and $120,000. The high-growth west side near Potranco Road and Masterson Road has seen asking prices rise as commercial and residential development pushes farther from the city center. Road frontage, flood zone status, and utility access shift the number on any given parcel.

Buyers comparing raw land to subdivided lots need to account for development costs the listing price does not show. A one-acre parcel outside city limits near Adkins or St. Hedwig might list at $60,000, but well drilling, septic installation, and driveway grading can add $15,000 to $35,000 before a foundation goes down. Inside city limits, utility tap fees and impact fees run $8,000 to $15,000 depending on the service district. That adds up. The gap between listing price and build-ready cost catches first-time land buyers off guard when they compare raw acreage to finished lots in established subdivisions.

Where Can You Find Available Land Parcels Near San Antonio?

Major listing platforms carry 800 to 900 active San Antonio land parcels at any given time. Zillow and Realtor.com show the broadest inventory, while Land.com tracks roughly 355 properties with acreage-specific filters. The strongest clusters of available land sit along corridors where development pressure has not yet absorbed available tracts, and each corridor fits a different buyer profile.

• West Side near US-90: The growth corridor around Masterson Road carries some of the largest available tracts in the metro, with parcels exceeding 30 acres still coming to market for buyers planning custom estate builds or agricultural operations. Per-acre pricing runs higher here than in outlying counties because municipal water and sewer infrastructure sits within reach, reducing buildout costs on large lots.
• South toward Atascosa County: Heading south past Loop 1604 puts buyers into Atascosa County, where parcels sit outside San Antonio city limits and carry lower tax bills. This corridor draws buyers who price out of Bexar County but still need a reasonable commute on I-37. Unimproved lots are more common here, so expect to budget for well drilling, septic installation, and potential road access improvements on top of the purchase price.
• East past Seguin: Guadalupe County east of San Antonio offers mid-range acreage with direct I-10 access. Buyers who commute into the city find this corridor practical since drive times from most parcels stay under 45 minutes. Lot selection runs smaller than the south and west corridors, but utility access tends to be more predictable because of existing rural residential development in the area.
• County tax sales: Bexar County and surrounding counties periodically auction tax-delinquent parcels at below-market prices, attracting cash buyers looking for raw land at steep discounts. The process requires title research, potential lien clearing, and patience with irregular auction schedules. Check each county’s tax assessor website for upcoming sale dates, and have a title company review any parcel before you bid.

Water Wells, Septic Systems, and Utility Considerations

Undeveloped parcels outside San Antonio city limits typically lack municipal water and sewer connections, which means buyers must budget for private wells and septic systems on top of the land purchase price. Drilling depth, soil type, and county permitting rules all influence infrastructure cost. A well in the Edwards Aquifer region might tap water at 150 feet, while lots in Medina County often require drilling past 300 feet.

Order a soil percolation test and a well depth estimate from a licensed driller before closing on raw land. Perc results determine whether the lot qualifies for a conventional gravity-fed septic or requires the costlier aerobic system with its ongoing maintenance contract. Parcels inside the Edwards Aquifer Contributing Zone carry additional permitting that adds 30 to 60 days to the schedule. Electric extension costs vary widely too. A lot half a mile from existing power lines might run $5,000, while a remote tract two miles out can exceed $25,000. Budget for every infrastructure line item during the option period.

Can You Finance a Raw Land Purchase in Texas?

Yes, you can finance raw land in Texas, but the terms look nothing like a standard home mortgage. Most lenders cap raw land loans at 15 to 20 years, charge interest rates 1 to 2 percentage points above residential mortgage rates, and require down payments of 20% to 50% depending on the parcel’s development status and road access.

Several alternatives to conventional land loans work well in the San Antonio market. USDA loans cover eligible rural parcels with no down payment if you plan to build a primary residence in the qualifying area. Owner financing is common on San Antonio acreage listings and lets you negotiate terms directly with the seller, often with lower upfront costs. Local credit unions and community banks sometimes offer lot loan programs with 10% to 15% down for parcels with existing utility access. Construction-to-permanent loans consolidate the land purchase and build into a single closing if you break ground within 12 months.

What Zoning and Land Use Rules Apply Outside City Limits?

Most unincorporated land in Bexar County and surrounding counties has no traditional zoning. Texas law does not grant counties zoning authority, so parcels outside city limits face far fewer restrictions on what you can build or operate. That freedom comes with tradeoffs, because fewer rules also mean fewer protections from what your neighbor does next.

• ETJ overlay: San Antonio’s extraterritorial jurisdiction extends up to five miles beyond the city boundary. Within the ETJ, the city requires subdivision platting and enforces development standards even though traditional zoning does not apply. A 10-acre tract that looks completely rural may still fall under city platting requirements. ETJ boundaries also shift as the city annexes land, so a parcel outside city jurisdiction today could fall inside it within a few years. Confirm ETJ status with the city’s Development Services Department before making an offer.
• Deed restrictions still bind: Recorded deed restrictions run with the land and apply regardless of whether the county has zoning. Rural subdivisions across Bexar, Comal, Guadalupe, and Medina counties frequently restrict building materials, minimum square footage, livestock counts, setback distances, and commercial activity. These restrictions appear in the title commitment, but buyers should request and read the full recorded document during the option period because title summaries often omit critical details.
• Floodplain rules apply everywhere: FEMA floodplain designations apply to unincorporated land with the same force as city parcels. Bexar County enforces a local floodplain management ordinance that can restrict buildable area, require elevation certificates, and mandate flood insurance. Pull the FEMA flood map panel for any parcel before signing a contract because floodplain status directly affects construction costs, insurance premiums, and long-term resale value.
• Agricultural tax rollback: Land carrying an agricultural tax exemption receives a significantly lower assessment, but that benefit ends when the use changes. Converting ag-exempt acreage to residential triggers rollback taxes covering the previous five years of the difference between the ag rate and the full market-value rate. On larger tracts this amount can be substantial. Request the current ag valuation from the county appraisal district and factor potential rollback into the purchase budget.

Steps to Close on a Rural Acreage Purchase

Closing on rural acreage in the San Antonio area takes 30 to 60 days for financed purchases and as few as 10 days for cash deals. Cash closings move faster. The gap exists because title companies research unplatted tracts through decades of deed records, and most lenders require a completed boundary survey before they will fund the loan.

Cash buyers skip the appraisal and underwriting rows entirely, compressing the full sequence into roughly two weeks. Financed buyers should budget 3% to 5% of the purchase price for total closing costs on top of the down payment. Request a preliminary settlement statement at least five business days before the scheduled closing date so no unfamiliar line items appear for the first time when you sit down at the title company. One missing document can push the date back weeks.

The Bottom Line

Buying land near San Antonio comes down to three factors: price per acre, infrastructure costs, and financing terms. One-acre lots range from $40,000 to $250,000 depending on location and utility access. Parcels outside city limits typically require private wells and septic systems, which add real dollars on top of the purchase price. Raw land loans run 15 to 20 years with interest rates 1 to 2 percentage points above conventional mortgages, so the total cost of ownership looks different from a standard home purchase.

The upside is inventory and flexibility. With 800 to 900 active parcels available across major listing platforms, buyers have options in nearly every direction from the city. Unincorporated land in Bexar County and surrounding counties carries fewer restrictions since Texas law does not grant counties zoning authority. That freedom gives buyers room to build on their terms, but it also means doing the due diligence on water, utilities, and land use before closing.
