Monthly and 10-year ownership cost calculations for new Sitterle homes at Willis Ranch. Focus on the very low HOA ($84/month) and full benefit of Bexar County 2025 senior tax exemptions.
Willis Ranch's true cost advantage comes from two factors: very low HOA dues ($84/month, the lowest in the San Antonio market) and Bexar County property taxes with 2025 senior exemptions (no MUD tax like Kendall County).
This is the right community to model if you're asking: "What's the lowest total monthly obligation for new construction in the San Antonio area?"
Willis Ranch is in Bexar County — same county as Hill Country Retreat. This means the same 2025 exemption structure applies. No MUD tax like Kendall County. Property tax calculation is straightforward.

The positioning:

If you purchase a $550,000 Willis Ranch home at age 65 and own it for 10 years:
| Category | 10-Year Total | Notes |
|---|---|---|
| Property tax (school frozen; county/city drift 1.5%/yr) | $112,090 | School ceiling locked at age 65; Bexar County, city, hospital district drift with appraisals |
| HOA (minimal increases) | $11,037 | 2% annual assumed increase |
| Homeowners insurance | $19,800 | New home; may increase modestly |
| Utilities | $15,600 | Modest increases assumed |
| Maintenance & repairs | $24,000 | New construction; warranty covers major structural/systems |
| Total 10-year carrying cost | $182,527 |
What this means: Over 10 years, owning a $550,000 Willis Ranch home costs approximately $182,527 in carrying costs. Compare to Hill Country Retreat at $350K ($138,200 over 10 years) — Willis Ranch costs more annually because the higher purchase price carries higher absolute property taxes, even at the same Bexar County rate.
If Willis Ranch appreciates to $660,000 after 10 years (~2%/year), you exit with $110,000 in appreciation. After long-term capital gains tax at 15%, net appreciation is roughly $93,500. Net cost of ownership: $182,527 carrying costs minus $93,500 appreciation = approximately $89,027 net cost to own for 10 years.
Willis Ranch offers new construction (like Regency at Esperanza) at a price point and carrying cost (like Hill Country Retreat) with Bexar County taxes (better than Kendall MUD).
The tradeoff:
If you're willing to accept those tradeoffs in exchange for $1,452/month carrying cost on a new $550K home — with the lowest HOA in the market at $84/month — Willis Ranch is the strongest new construction value in Bexar County.
