Why are homes in Boerne, Texas so expensive?

Boerne prices are driven by structural scarcity, not hype. Kendall County grew 20.3 percent from 2020 to 2025 on domestic migration, Boerne ISD has six straight A ratings, Hill Country terrain and groundwater regulation limit how densely land can be developed, and I-10 puts San Antonio jobs 31 miles away.

About the price number itself

Public median and average price figures for Boerne vary widely by source, by ZIP code and by month. Zillow's reported average home value for Boerne was roughly $554,983 as of September 2026 (Zillow, Boerne home values). That is a third-party estimate produced by a model, not a closed-sale statistic, and it moves. Anyone quoting you a single Boerne median as settled fact is quoting a snapshot. Ask a local agent to pull current MLS sold data for the specific ZIP, price band and property type you are actually shopping.

What does not move month to month is the set of reasons the number is high. Those are below.

Cause 1: demand is real and it is measurable

Kendall County grew 20.3 percent between 2020 and 2025, from an estimated 44,568 to 53,289 residents, and most of that growth came from domestic migration — households moving in from elsewhere in the country (Community Impact).

Domestic in-migration is the specific kind of demand that lifts prices fastest, because in-migrating buyers arrive with equity from a prior sale and are pricing against what they left, not against local wage data. The City of Boerne's 2020 census count was 18,084; current city-level figures are estimates (World Population Review).

Cause 2: the school district is a price input

Boerne ISD has earned an "A" rating from the Texas Education Agency for six consecutive years, including the 2024 and 2025 rating years, scoring 92 points in 2024–2025 with 20 distinction designations (Boerne Star; TEA).

A rating record that long is not a marketing line; it is the thing relocating families sort on before they look at a single listing. It concentrates demand inside district boundaries and pulls price with it. Note that the district rating is not the campus rating — the Boerne Star reported lower grades for Viola Wilson, Currington, Herff and Kendall elementaries in the same cycle.

Cause 3: supply is constrained by terrain and by water

This is the part that outsiders miss. Hill Country land does not subdivide like flat coastal prairie. Slope, rock, floodplain along the creeks, and the cost of running utilities up and across grade all cut the number of finished lots you get out of a given tract.

Water compounds it. Boerne's drinking water comes from three sources — Canyon Lake surface water purchased through the Guadalupe-Blanco River Authority, Boerne City Lake, and local wells in the Trinity Group aquifers (City of Boerne). Groundwater across Kendall County is regulated by the Cow Creek Groundwater Conservation District, which sets drought stages and pumping rules using roughly 42 monitor wells, stream gauges on Cibolo Creek and the Guadalupe River, and more than 100 rain gauge sites (Cow Creek GCD).

A development that cannot document water cannot get built at the density its pro forma assumed. Constrained new supply plus measurable in-migration is the whole price story in one sentence.

Cause 4: I-10 makes it commutable

Boerne sits roughly 31 miles northwest of San Antonio on Interstate 10, a 30-to-45-minute drive to downtown depending on traffic (City-Data). That is close enough to hold a San Antonio job and far enough to be a genuinely different place. Towns with that combination — real separation, real access — price at a premium over towns with only one of the two.

What the price does not include: the tax bill

The 2025 adopted rates for a home inside the city limits in Boerne ISD, per $100 of taxable value:

Any special district on the parcel — a MUD, the WCID, the groundwater district — adds its own line; pull the entity list for your specific parcel from Kendall Appraisal District. Texas reappraises at market value annually, so a rising Boerne market raises your bill, not just your equity — the 10 percent homestead cap limits the annual increase in net appraised value only after a homestead exemption is in place.

The failure mode: a buyer qualifies on a payment built from the seller's current tax bill, which may reflect an exemption the buyer does not yet have, or a valuation set before the last run-up. Ask a lender to underwrite the payment using a full, unexempted valuation, and ask Kendall Appraisal District what will apply to you.

Is it overpriced, or just priced?

Those are different questions. Overpriced means the number is unsupported by fundamentals. Boerne's number is supported by fundamentals — in-migration, schools, constrained buildable supply, highway access — that would each take years to reverse. That does not make any individual listing correctly priced. Individual houses are mispriced in both directions every week, and that is what comparable sales analysis is for.
