Monthly and 10-year ownership cost calculations for established resale homes at Hill Country Retreat. All-in costs including property tax (with 2025 Bexar exemptions), HOA, insurance, utilities, and maintenance estimates.
Hill Country Retreat's true cost has five main components: property tax (heavily influenced by 2025 Bexar County exemptions), HOA, homeowners insurance, utilities, and maintenance/repairs. We break each down separately, then model full monthly and 10-year scenarios at three price points.
Bexar County's November 2025 constitutional amendments dramatically changed property tax for buyers 65+. We model three age scenarios: pre-65, age 65–70, and age 70+ (with school tax freeze established).
Bexar County property tax has three parts: school district, county, and city (for properties within San Antonio city limits). Hill Country Retreat is in the Alamo Ranch area — check your specific property's tax district, as rates vary by school district served.
Base assumptions (2025):
Homestead exemptions (2025):
| Appraised value | $350,000 |
| Less general homestead exemption | -$140,000 |
| School taxable base | $210,000 |
| School tax at 1.35% on $210K | $2,835/year |
| Bexar County at 0.32% on $350K | $1,120/year |
| City of SA at 0.55% on $350K (no over-65 city exemption) | $1,925/year |
| Hospital district at 0.26% on $350K | $910/year |
| Total annual property tax | $6,790/year |
| Monthly property tax | $566/month |
| Appraised value | $350,000 |
| Less general homestead | -$140,000 |
| Less over-65 school exemption | -$60,000 |
| School taxable base | $150,000 |
| School tax at 1.35% on $150K | $2,025/year |
| Bexar County at 0.32% on $350K | $1,120/year |
| City of SA at 0.55% on $265K (less $85K exemption) | $1,458/year |
| Hospital district at 0.26% on $350K | $910/year |
| Total annual property tax (year 1) | $5,513/year |
| Monthly property tax (year 1) | $459/month |
Key point: The 2025 Bexar exemptions save a 65+ buyer approximately $1,215/year vs. pre-2025 rates — real savings, but the full tax stack (school + county + city + hospital) on a $350K home still runs $5,513/year. Model the full number, not just the school district exemption math.
| School tax — frozen at age 65 ceiling | $2,025/year (locked) |
| Bexar County (drifts with appraisal) | ~$1,120–$1,300/year |
| City of SA (drifts with appraisal) | ~$1,458–$1,650/year |
| Hospital district (drifts with appraisal) | ~$910–$1,050/year |
| Total annual property tax (frozen school, others drift) | ~$5,513–$6,025/year |
| Monthly property tax range | ~$459–$502/month |
Key point: The school tax freeze locks ~38% of your total bill. County, city, and hospital district taxes continue to drift upward with appraisals — but more slowly than without the freeze. Over 15 years at 5% annual appraisal growth, the freeze saves approximately $30,000–$40,000 in school tax alone.
Hill Country Retreat HOA is $556.50 per quarter, which equals $185/month annually. This includes trash service ($55.50/quarter). There is no separate garbage bill.
The HOA funds:
Monthly HOA: $185
Insurance costs vary significantly based on home age, construction, square footage, and coverage level. Hill Country Retreat homes built in the 2000s–2010s are largely masonry/concrete construction, which qualifies for moderate insurance rates.
Estimate range for a $350,000 Hill Country Retreat home:
We use $150/month ($1,800/year) as a reasonable middle estimate for moderate coverage.
San Antonio's climate drives significant cooling costs May–September. Winter heating is minimal. Average utility costs for a single-family home at Hill Country Retreat:
Annual estimate: $1,200–$1,800 depending on usage and cooling habits.
Monthly average: $125 (conservative estimate assuming standard usage and no excessive irrigation)
Homes at Hill Country Retreat are 10–20 years old (resale inventory from earlier phases). Budget for routine maintenance and occasional repairs:
Monthly estimate: $200 (conservative reserve including routine maintenance and unexpected repairs)
| Cost Component | Monthly | Annual |
|---|---|---|
| Property tax (65+, full Bexar stack) | $459 | $5,513 |
| HOA (includes trash) | $185 | $2,220 |
| Homeowners insurance | $150 | $1,800 |
| Utilities (electric, water, gas) | $125 | $1,500 |
| Maintenance & repair reserve | $200 | $2,400 |
| Total monthly carrying cost | $1,119 | $13,433 |
Key insight: For a 65+ buyer at a $350,000 Hill Country Retreat home, monthly carrying costs are approximately $1,119. This includes everything except purchase price and closing costs. If you have the home paid off, this is your total monthly obligation.
If the buyer is under 65, property tax increases from $459 to $566/month (an additional $107/month, driven by losing the $60K over-65 school exemption and the $85K City of SA over-65 exemption), bringing total monthly costs to approximately $1,226/month.
The drop occurs once you turn 65 and file for the exemptions — not gradual. Plan to see your tax bill decrease meaningfully in the year you qualify.
If you purchase a $350,000 Hill Country Retreat home at age 65 and own it for 10 years:
| Category | 10-Year Total | Notes |
|---|---|---|
| Property tax (school frozen at year 65, county/city drift) | $59,000 | School portion locked; Bexar County, city, hospital drift ~1.5%/yr with appraisal |
| HOA dues | $22,200 | Assume ~2% annual increase |
| Homeowners insurance | $18,000 | Assume flat rate; may increase |
| Utilities | $15,000 | Assume modest increases |
| Maintenance & repairs | $24,000 | Conservative, includes minor roof/HVAC work |
| Total 10-year carrying cost | $138,200 |
What this means: Over 10 years, owning a $350,000 home at Hill Country Retreat costs approximately $138,200 in carrying costs (property tax, HOA, insurance, utilities, maintenance). This is separate from purchase price, closing costs, and any home appreciation or depreciation.
If the home appreciates to $440,000 after 10 years (~2.3%/year, conservative for San Antonio), you exit with $90,000 in appreciation before capital gains tax. Net cost of ownership: $138,200 in carrying costs minus $90,000 appreciation = $48,200 net cost to own for 10 years — roughly $400/month in real terms.
Before November 2025, Bexar County's over-65 exemptions were much smaller ($10,000 school exemption, no additional general homestead increase). The 2025 constitutional amendments quintupled the available exemption.
For the same $350,000 home:
This structural change happened in November 2025. Anyone buying Hill Country Retreat now (2026) benefits immediately. This is the most significant tax advantage change in San Antonio's property tax code in the last decade.
