How to Buy Land to Build Your Home in Wilson County, Texas
Buying land to build your own home in Wilson County, Texas is one of the most rewarding paths to rural ownership — and one of the more complex ones if you've never done it before.
Unlike buying a finished home, you're making two major decisions instead of one: first, finding and purchasing the right land; second, designing and building the home you actually want on it. Done right, you end up with exactly what you envisioned in the location you chose. Done without the right guidance, you can end up with land that won't support what you planned, utilities that cost more than you expected, or a site that doesn't finance the way you assumed.
James Peterson, ALC and Barbara Peterson are broker-owners of United Country Real Estate | Texas Ranch and Home in Floresville, Texas. Helping buyers find and purchase land for building is one of the most common buyer requests they handle throughout Wilson County. This guide walks you through what the process actually looks like.
Step 1: Get Clear on What You Actually Need the Land to Do
Before you look at a single listing, be specific about what you're buying land for — because it changes everything about which properties are viable.
Ask yourself:
How much land do I actually want? Some buyers want 2 acres for privacy and a modest homesite. Others want 20 acres for horses, a shop, livestock, or hunting. Knowing your real number before you start prevents you from falling in love with properties that don't fit your life.
Am I planning to build immediately or hold and build later? If you're building within 12 months, financing, utilities, and buildability are immediate concerns. If you're buying land to hold and build in 3–5 years, the considerations shift slightly.
What kind of home am I planning to build? A modular or manufactured home has different site requirements than a site-built custom home. Some Wilson County areas or deed-restricted communities have minimum square footage, construction type, or exterior material requirements. Know what you want to build before you evaluate where you can build it.
Do I want to be in a deed-restricted community or on unrestricted land? This is one of the most important decisions for Wilson County land buyers. Both options exist here — and they have very different implications for what you can do on your property.
Step 2: Understand the Deed Restriction Question
This deserves its own section because it's one of the most common sources of buyer disappointment when it isn't addressed early.
Deed-restricted communities in Wilson County and La Vernia typically require:
Minimum home size (often 1,400–2,000+ square feet)
Specific exterior construction materials (brick, stone, or stucco on a minimum percentage of exterior walls)
Setback requirements from property lines and roads
Restrictions on outbuildings, barns, or secondary structures
Restrictions or prohibitions on livestock or agricultural animals
Requirements for architectural approval before construction
These restrictions exist to maintain community character and protect property values — and for buyers who want those protections, they're appropriate. But for buyers who want to build a large metal barn, run cattle or horses, keep chickens, or build a shop before building their home, deed-restricted communities are usually the wrong fit.
Unrestricted land in Wilson County — which represents most rural acreage outside of platted subdivisions — allows you to:
Build any construction type (site-built, modular, manufactured)
Build in any order (shop first, house later, or simultaneously)
Keep livestock, agricultural animals, or working operations
Build outbuildings without approval
Generally do what you want with the land, subject only to county regulations
Wilson County does not have county-wide zoning in the way that urban counties do. That means most rural land outside city limits and deed-restricted subdivisions is genuinely unrestricted — and that's one of the reasons so many buyers seek it out.
James and Barbara always verify restriction status before showing a land buyer a property. "Is this land unrestricted?" is one of the first questions they ask on behalf of every land-to-build buyer.
Step 3: Evaluate the Property for Buildability
Finding land you love is only part of the equation. The land also needs to work for building. Here's what to evaluate:
Utilities Access
Electricity: Is there a power line along the road frontage? What is the cost to connect? Some rural Wilson County properties have electricity readily accessible; others require extending power lines at significant cost. Get a quote from the electric cooperative before you make an offer.
Water: Can you drill a well? What is the expected depth and yield for wells in that part of Wilson County? Well drilling costs in South Texas vary based on depth — roughly $15–$25+ per foot drilled plus casing and pump. Talk to a local well driller before you close.
Septic/sewage: Will you need an on-site sewage facility (septic system)? Almost certainly yes, on rural Wilson County land. Have a licensed OSSF evaluator assess the soil before you close — soil conditions that don't support a conventional drain field will require a more expensive aerobic system.
Internet: If remote work depends on reliable internet, verify coverage at the specific location before buying. Fiber, fixed wireless, and Starlink are available across much of Wilson County, but coverage varies.
Topography and Drainage
The land needs to be buildable — which means it should have an area with appropriate elevation, drainage, and stability for a home foundation. South Texas land is generally favorable for building, but properties with significant drainage issues, floodplain encroachment, or heavy clay soils that don't drain well can create foundation challenges.
Walk the land after significant rainfall if possible. See where water sits and where it drains.
Floodplain
Check FEMA flood maps before you buy any Wilson County land. Properties along the San Antonio River, Cibolo Creek, and other drainages have floodplain areas. Building in a floodplain requires elevation certificates, flood insurance, and may restrict what you can build and where.
FEMA flood maps are available at msc.fema.gov — search by address or coordinates.
Road Access
Your buildsite needs to be legally accessible and practically navigable for construction equipment, concrete trucks, and eventually your daily driving. County road frontage is the gold standard. Easement access can work but needs to be legally established and adequate for heavy equipment.
Soil and Site Conditions
For agricultural buyers or anyone planning significant site work, soil composition matters. A basic soil test can reveal whether you're working with sandy loam, heavy clay, caliche hardpan, or other compositions that affect drainage, foundation type, and agricultural productivity.
Step 4: Understand the Permitting and Building Process in Wilson County
Wilson County does not have a county-wide building department in the way that urban counties do. Outside of city limits, building permit requirements are more limited than in Bexar County — but they're not zero.
On-site sewage facility (septic) permit: Required by the Texas Commission on Environmental Quality (TCEQ) and administered locally. Your septic installer will handle the permit process, but you need to have the site assessed first to determine which type of system is appropriate.
Electrical permit: Your electrician will pull the required permits for the electrical service connection.
Within city limits of Floresville or other incorporated towns: Building permits, inspections, and zoning requirements apply. The city of Floresville has its own building department for properties inside city limits.
Manufactured or modular homes: These have their own permit and installation requirements under Texas law, administered through the Texas Department of Housing and Community Affairs (TDHCA).
For most rural Wilson County land purchases, the regulatory environment is relatively light compared to urban markets. That's part of the appeal — but it also means that buyers need to do their own due diligence on site suitability rather than relying on the county to catch problems.
Step 5: Finance the Land Purchase
Financing land in Wilson County is different from financing a home purchase. Here's what buyers need to know:
Most residential mortgage lenders don't do land-only loans. If you're buying land without an existing home on it, you typically need a land loan — not a residential mortgage.
Agricultural lenders are your best resource. Capital Farm Credit, AgTexas Farm Credit, and similar institutions specialize in rural land loans. They understand how to evaluate Wilson County land and can structure loans for buyers planning to build.
Down payments are higher for land loans. Expect 20–30% down for a land purchase loan.
Construction-to-permanent loans are worth exploring if you're building within 12–24 months of purchase. These products combine the land purchase and home construction financing into a single loan that converts to a permanent mortgage when construction is complete. Some lenders offer these as a one-time-close product that avoids a second closing cost.
Cash is common. Many Wilson County land purchases below $200,000 are cash transactions, which simplifies the process significantly.
James and Barbara can refer buyers to lenders experienced in Wilson County land and construction financing so you're not starting from scratch.
What Land to Build On Costs in Wilson County
Current market ranges for buildable land in Wilson County:
1–5 acres near La Vernia or Floresville, good road frontage: $40,000–$150,000+ depending on size, utilities, and location
5–20 acres rural residential, county road access: $80,000–$300,000+ depending on location, water, and improvements
Unrestricted acreage further from town: $3,500–$6,000/acre as a rough range, varying with features
Lots in deed-restricted rural communities: $40,000–$120,000+ depending on community amenities and location
These are ranges. Specific pricing depends on what's on the ground, where it is, and what the current market looks like. James and Barbara pull current comparable sales for any land you're seriously evaluating.
Frequently Asked Questions From Land-to-Build Buyers
Can I put a manufactured or mobile home on rural Wilson County land? Generally yes on unrestricted rural land, subject to TDHCA requirements for installation and permitting. Some deed-restricted communities prohibit manufactured homes — verify before purchasing if this is your plan.
How long does it take to build a home in Wilson County? A site-built custom home typically takes 9–18 months from breaking ground to move-in. A modular home can be faster — 4–8 months in many cases. Factor this into your timeline and housing arrangements.
Do I need a real estate agent to buy raw land in Wilson County? Not legally — but the due diligence on raw land is more complex than on a finished home. James Peterson's ALC designation reflects deep expertise in exactly this type of transaction, and having that experience on your side costs you nothing as a buyer (the seller pays the commission).
Can I get ag valuation on land I'm building on? Possibly — if you continue qualifying agricultural activity on the undeveloped portion of the land. The homesite area itself is typically assessed at market value while the remainder retains ag valuation if qualifying use is maintained. Discuss this with Wilson CAD before closing.
