Housing does most of the damage
Almost the entire gap between two cities is shelter. Tradable goods cost roughly the same everywhere; land does not. A one-bedroom runs about $1,450 a month in Aurora and $1,150 in San Antonio — $300 a month apart, or $3,600 a year.
Buying sharpens the same story. Median home prices sit near $450,000 in Aurora against $290,000 in San Antonio — at 20% down, about $32,000 apart in cash up front, before property tax rates in Colorado and Texas enter the picture.
The price-to-rent ratios diverge enough to change the buy-versus-rent answer: about 21 in San Antonio versus 26 in Aurora. A ratio near 15 or lower makes buying straightforward; near 20 or above, renting and investing the gap is usually the stronger play. Which means the right answer can genuinely be to buy in one and rent in the other.
Taxes the index leaves out
Texas levies no state income tax; Colorado does. On $100,000 that is commonly $4,000–$8,000 a year of take-home, enough to offset a real gap in rent. Cost-of-living indexes exclude income tax, so comparing them alone misleads here.
The offset is rarely free, though. States without an income tax usually recover it elsewhere — property tax rates in Texas and sales tax are the usual places to look. If you plan to buy rather than rent, run the property tax number before assuming the no-income-tax state is cheaper.
Getting around
Aurora is served by limited transit; San Antonio is effectively car-dependent.
Work, weather, and what else is different
Aurora is a large metro of about 3.0M and growing steadily; San Antonio is a large metro of about 2.7M and growing fast.
Both metros have real employment in healthcare, which matters if you want to move without changing careers — your experience is legible to employers in both. Aurora also leans on aerospace/defense and logistics, with employers like Buckley Space Force Base and UCHealth/Anschutz Medical Campus. San Antonio leans on military/defense and tourism, with Joint Base San Antonio and USAA.
The part spreadsheets leave out. Aurora: Semi-arid high plains: January highs near 45°F/lows 19°F, July highs near 88°F/lows 59°F, low humidity with over 300 sunny days. San Antonio: Hot subtropical climate with mild winters near 40°F lows and very hot summers with July highs near 95°F.
Part of the Denver-Aurora-Lakewood MSA but with meaningfully lower housing costs than Denver proper; Colorado's flat state income tax is 4.4% with no city add-on (Denver-area cities do levy small flat monthly occupational taxes, not percentage income tax). No Texas state income tax, and one of the largest concentrations of military installations (Joint Base San Antonio) of any US metro.
