Why Boerne acreage
Boerne (Kendall County) draws acreage buyers for a specific combination of factors: Boerne ISD schools (consistently top-ranked in the region), proximity to San Antonio's medical and executive employment, Hill Country topography (live oaks, limestone, view potential), and a buyer pool that values privacy and lifestyle. Acreage sub-markets include Cordillera Ranch (the high-profile gated luxury community), Anaqua Springs Ranch, River Mountain Ranch, Tapatio Springs, and the broader unincorporated Kendall County tracts ranging from 2 acres to 100+ acres. Pricing and diligence requirements vary widely across these sub-markets.
Well — capacity, water rights, and aquifer context
Most Boerne acreage tracts outside municipal utility service rely on private well. The critical diligence questions: what's the well's gallons-per-minute capacity, what's the aquifer depth, what's the well casing material and age, and what does the water quality look like (bacteria, hardness, mineral content). Trinity Aquifer is the dominant aquifer in the area, with varying yield depending on tract location. New wells typically require drilling — costs vary by depth and casing requirements, often $15-40+ per foot, with total well install ranging widely by depth. Water rights in Texas follow the rule of capture for groundwater under most circumstances, but Hill Country aquifer pumping is increasingly regulated — confirm jurisdiction and any groundwater conservation district rules. A well capacity test should be part of diligence for any well-served tract.
Septic and OSSF feasibility
Septic — formally OSSF (on-site sewage facility) under TCEQ regulation — is required for any acreage build outside sewer service. Soils must percolate to support a conventional septic drain field, or alternative systems (aerobic, low-pressure dosing) are required at higher cost. A perc test should be conducted as part of diligence on any vacant tract you intend to build on. Kendall County and surrounding jurisdictions have specific OSSF permitting requirements; designated maintenance providers are typically required for aerobic systems. The single most expensive surprise on Hill Country acreage is buying a tract where soils don't perc and the alternative system cost materially changes the build budget. Always perc test before option period expires.
Roads, easements, and access
Road access on Boerne acreage spans paved county-maintained roads, gravel county-maintained roads, recorded private easements over shared driveways, and unrecorded historical access. The diligence questions: is the access road county-maintained or private; if private, what's the recorded easement structure and maintenance agreement; is there legal access from a public road to the parcel; and what's the road condition through wet weather. Private road associations vary in funding structure and assessment authority. Insurance and financing both look at access quality. Confirm legal access through the title commitment and physical access through a site visit (preferably in different weather conditions).
Deed restrictions and HOAs
Gated communities (Cordillera Ranch, Anaqua Springs Ranch, others) carry full HOA structure with architectural review, dues, and use restrictions. Unincorporated acreage often carries deed restrictions that survived from the original subdivision plat — minimum home size, building materials, livestock restrictions, RV storage rules, mobile home prohibitions, and short-term rental restrictions. Confirm restrictions through the title commitment and recorded plat. STR plans on Boerne acreage particularly require careful review — some subdivisions explicitly prohibit STR; others are silent; county-level STR rules can also apply.
Wildlife, environmental, and karst
Hill Country acreage carries environmental considerations that buyers outside Texas often don't anticipate. Golden-cheeked warbler critical habitat overlays affect parts of Kendall County and surrounding Hill Country counties — habitat clearance during nesting season is restricted, and mitigation may be required for development in designated habitat. Karst geology (caves, sinkholes, underground features) affects buildability and septic siting. Endangered species habitat consultation (USFWS) may be required for development in designated zones. Wildlife management agricultural exemption can offer property tax savings on qualifying acreage but requires active management plan compliance. Confirm habitat and karst overlay before relying on intended use.
Resale and exit dynamics
Boerne acreage resale liquidity is real but slower than San Antonio in-town resale. The buyer pool is finite and somewhat seasonal (spring and early fall tend to be strongest), and well-positioned acreage well-priced moves cleanly. Cordillera Ranch and named gated communities tend to be more liquid than unincorporated tracts because the buyer pool is better defined and HOA structure provides comparability. Custom-built acreage homes with idiosyncratic floorplans, unusual materials, or extreme remoteness run thinner buyer pools at exit. Acreage buyers planning to hold 7-15+ years can absorb more idiosyncrasy; buyers anticipating shorter holds should bias toward more broadly appealing tracts and homes.
