The honest financial comparison, what your Illinois equity buys in the Austin-San Antonio corridor, and the practical steps before you list your home
Illinois has a 4.95% flat income tax. Most retirement income — Social Security, pension distributions, and 401(k) withdrawals — is exempt in Illinois, which reduces the income tax comparison somewhat. Where Illinois clearly loses is property taxes: Cook County effective rates of 2.0–2.5% (before exemptions) on a $400K home mean $8,000–$10,000/year in property taxes. Texas 65+ primary owners on a comparable home pay $3,800–$5,200/year. The property tax savings of $2,800–$4,800/year are consistent and permanent.
| Tax Category | Illinois (Cook County) | Texas (65+ primary) |
|---|---|---|
| State income tax on $80K income (much exempt) | ~$500–$1,500/yr | $0 |
| Property tax on $400K home | ~$8,000–$10,000/yr | ~$3,800–$5,200/yr |
| Annual savings moving to TX | ~$3,300–$5,800/yr | |
For IL buyers with primarily Social Security and pension income, the income tax savings are modest since IL exempts most retirement income. The dominant financial benefit is the property tax reduction — real, permanent, and meaningful on a fixed income.
Chicago north shore and western suburb homeowners who purchased before 2012 typically carry $200,000–$450,000 in equity. This equity funds a Sun City Texas purchase in the $300K–$450K range — often with cash remaining — or a Kissing Tree home in the $350K–$500K range. Illinois buyers are among the most motivated by pure property tax relief; the comparison of $8,000–$10,000/year in Cook County taxes vs $3,800–$5,200/year in Williamson County is a powerful argument.
| Texas Community | Price Range | HOA | Best For |
|---|---|---|---|
| Sun City Texas (Georgetown) | \$300K–\$700K | ~\$100/mo | Value, 54-hole golf, maximum amenity scale |
| Kissing Tree (San Marcos) | \$350K–\$700K | ~\$263/mo | Hill Country terrain, halfway between Austin and San Antonio |
| Trilogy at Rough Hollow | \$600K–\$1.5M+ | \$350–\$450/mo | Lake Travis access, luxury product, closest to Austin |
| Villas at Kissing Tree | \$270K–\$450K | \$255/mo (lawn incl.) | Best value entry to Kissing Tree amenities |
Sun City Texas is the most common landing point for IL buyers — the combination of low HOA, property tax reduction from Cook County rates, and established community matches what Chicago-area retirees typically want. Buyers from more rural IL markets with lower equity may target the Villas at Kissing Tree for the entry price point.
