Moving from Chicago to San Antonio Cost of living, home prices, and what the same budget buys

Patrick's Quick Answer

Moving from Chicago to San Antonio is a high-tax state to no-income-tax state move with closer home prices than most people expect. The Chicago city median home sale price sits near $426,000 while the San Antonio city median sits near $265,000 (Redfin, three months to August 2026), about a 1.6-to-one difference, the closest gap in this series so far. On top of price, Illinois's flat 4.95% state income tax disappears, worth roughly $4,700 a year at a $100,000 household income and about $7,100 to $7,200 at $150,000, and the combined sales tax drops from 10.5% in Chicago to 8.25% in San Antonio. The honest catch is that both cities carry high property tax bills: Cook County's effective rate runs near 1.98% versus Bexar County's typical combined rate near 2.27%, and Chicago's famously tough winters trade for San Antonio's long hot summers. Rate and price are separate inputs, so the complete monthly payment, not the price tag, is what you compare.

I work this move from both ends: I originate home loans statewide across Texas, including for Illinois buyers moving here, and I sell real estate around Greater San Antonio, so Chicago clients get the financing and the contract side coordinated in one plan. This post is the Chicago city-level comparison, with the numbers dated and the sources named. The deeper relocation playbook, with the corridor comparisons and blank payment worksheets, is in the relocation hub.

Why this particular move keeps happening

Illinois to Texas is one of the most traveled state-to-state routes in the country, and Chicago is the biggest origin city on it. In the most recent IRS migration data, 2022 to 2023, Texas was the single most common out-of-state destination for Illinois movers, with about 46,400 tax returns relocating from Illinois to Texas (IRS SOI migration data); Texas A&M's Real Estate Center estimates the census-based flow at 21,000 to 25,000 new Illinois residents a year. Illinois also posted a net loss of roughly 55,600 people in that same IRS window, and the reasons are the reasons most Chicago transplants recite in the same order: a flat 4.95% state income tax on every paycheck, a combined sales tax among the highest in the country, a median home that costs about 1.6 times its San Antonio counterpart, and a commute that averages about 35% longer than San Antonio's.

San Antonio answers with a different set of tradeoffs: no state income tax, a lower combined sales tax, a median home about $161,000 cheaper, a shorter average commute, and a military and healthcare job base at Joint Base San Antonio, in exchange for hot, humid summers, a property tax system that leans hard on a bigger bill, and the loss of a four-season lake city. Neither city is better; they answer different questions. Because the price gap here is far smaller than in the California-to-Texas moves covered elsewhere in this series, the tax lines and the property tax math carry more of the story, and this post is built around that.

The two markets, side by side

City-level figures from the same tracker put this pairing in perspective: Chicago's median runs about 1.6 times San Antonio's, which is real but nothing like the three-to-four-to-one gaps from the California cities in this series. One honest caveat before the table: Chicago's city median blends a condo-heavy inventory near the lake and downtown with vintage single-family blocks in the neighborhoods, so $426,000 buys very different property types depending on where you look, and the San Antonio median points more consistently at a single-family house:

Two honest caveats. First, a city median hides a wide range of neighborhoods in both places, and Chicago spans everything from high-rise condos to brick two-flats and North Side walk-ups, so treat these figures as orientation, not a shopping list. Second, different trackers measure differently: Zillow tracks average home value rather than median sale price, and metro-level reads such as the SABOR figure run above the San Antonio city median, which is a smaller geography. The gap to San Antonio is clear under every method; the exact size depends on which definition you use.

Cost of living: closer than the California moves, still meaningful

Cost of living indexes do not agree on one number, which is normal, but they agree on the direction and roughly on the size. BestPlaces puts Chicago about 15.8% more expensive than San Antonio on its compare-cities index (115.8 versus 100), and its cost-of-living calculator says a $45,000 Chicago budget goes about as far as $37,626 in San Antonio. Salary.com lands San Antonio roughly 18% to 22% less expensive. Housing and rent are the big drivers, and the tax structure underneath adds a layer this pairing shares with no other move in the series:

The pair-specific number worth holding onto: a typical Chicago 2-bedroom rent of about $1,915 a month is more than the principal, interest, and property tax on the median San Antonio home in the payment math below. For renters especially, this move is often the move from writing a rent check to writing a mortgage check for about the same money.

State income tax: a flat 4.95% that disappears

Illinois runs a flat individual income tax of 4.95% of net income, with a $2,775 exemption per filer and dependent in 2026. Texas has no individual state income tax. There are no brackets to manipulate, so the math is simple: working households in Chicago lose a real line from every paycheck, and that line disappears on arrival in Texas. For a typical household the savings land like this:

Three honest qualifications so this stays useful. First, Illinois exempts retirement income, including Social Security, pensions, and 401(k) and IRA withdrawals, so the income tax savings of this move are largest for working households and smallest for retirees, whose money is already untaxed in both places. Second, the income tax savings are partly offset by the higher property tax and sales tax structure discussed in the next sections, so the net depends on the house you buy and how you spend. Third, any planning around the sale of a Chicago home, capital gains, or investment income is a qualified tax professional's question, not a mortgage estimate.

Property taxes: the pairing where both bills are high

This is the section where this pairing differs from every other move in the series, because both cities are high property tax markets. Cook County's median effective rate runs near 1.8% to 2.0% of market value, with a commonly cited median effective near 1.98%, one of the highest in the country. Bexar County carries a median effective rate near 1.55% and a typical combined in-city rate near 2.27% of taxable value, also well above the national average. In percentage terms these are neighbors; in dollars they are not, because the median Chicago home costs about 1.6 times the median San Antonio home.

The Chicago quirk that confuses every transplant: the sticker rate on a Cook County bill looks like about 7%, because residential property is assessed at 10% of market value and the county then applies a state equalization factor so the aggregate lands at the state-required 33.33% used everywhere else in Illinois. The effective rate on market value is the number that matters, near 2%, not the nominal rate on the bill. In Texas, the rate you see on the bill is close to the rate you actually pay, since appraisal districts work from full market value. The San Antonio property tax system explained walks through every layer.

• The rate is a wash; the dollar bill is not. Roughly 1.98% effective in Cook County versus roughly 1.55% median effective in Bexar, but the median Chicago home costs about $161,000 more, so the median Chicago tax bill runs near $8,400 a year versus near $4,100 in San Antonio, about double.
• The sticker rate means nothing across state lines. Chicago's nominal ~7% and San Antonio's ~2.27% are not comparable numbers, because Illinois assesses at a fraction of market value. Compare effective rates or, better, dollar bills for the specific address.
• Both states run homestead exemptions that are filed, not assumed. Texas's state exemption is $140,000 for 2025 with a 10% annual cap on homestead appraisal growth, and the homestead exemption filing is planned after closing, never assumed from the seller's bill. Illinois homeowners similarly verify their exemption status on record, so the filing habit travels.
• Both markets have extra assessment layers. Chicago runs special service districts and supplemental charges on top of the base bill; Texas has MUD and PID assessments in master-planned communities such as Alamo Ranch and Johnson Ranch. The rule is identical on both ends: read the appraisal district record for the exact address and count every line in the complete payment.
• Appeals work on different clocks. Cook County runs a well-known protest window each year, and Chicagoans know the appeals timeline by heart. Bexar County's appraisal review board protest window has its own dates and deadlines, so the habit of checking and protesting is worth keeping, but on the Texas calendar, not the Illinois one.

The pair-specific takeaway: a Chicago buyer arriving in Texas trades one high property tax market for another, but on a lower price, so the median dollar bill runs about half. The exact number is always address-specific, and that is the number to budget on.

Sales tax: among the highest in the country to Texas normal

Chicago's combined sales tax rose to 10.5% on August 1, 2026, when the Regional Transportation Authority's share increased from 1.0% to 1.25%, putting the city near the top of the national list. San Antonio runs a combined 8.25% (Texas state 6.25% plus local shares). Both states start from the same 6.25% state rate, so the whole difference is local. In dollars, the gap is 2.25 points, which means about $22.50 stays in your pocket on every $1,000 of taxable purchases. That is a small line in a monthly budget but a real one on a family's annual spending, and it is one more reason the complete payment, not just the price, is the honest comparison.

Insurance: the line that usually surprises Chicago transplants

People assume the move to Texas raises their homeowners insurance, and this pairing is the one where the assumption is backwards on average. On a comparable policy, roughly $300,000 of dwelling coverage with a $1,000 deductible, 2026 trackers put Chicago at about $2,820 to $3,311 a year and San Antonio at about $2,365 to $2,866 a year (Insurify and Insure.com estimates), so the typical Chicago bill runs about $400 to $500 higher. Winter storm and water-damage claims drive the Cook County premium; Texas quotes lean on hail and wind exposure and roof age:

Two clarifications so this stays honest. These are averages and ranges, not quotes for your specific home: age, roof, claims history, and exact location all move the number in both states. The practical read for a Chicago buyer arriving in Texas: the insurance line usually improves, and it lands in your escrowed payment either way, so it shows up in your monthly number, not in a separate annual decision.

The same budget in both cities: the payment math

Let's run the comparison the way a buyer actually thinks about it: with one monthly budget, pointed at each city. The math below is illustrative, rounded, and dated October 2026. It assumes a 30-year fixed loan at an illustrative 6.5% rate with 20% down, and property taxes at each side's typical effective rate (about 1.98% in Cook County, about 1.55% in Bexar County). This is example arithmetic for comparison, not a rate quote, not a tax quote, and not an approval number for your file. Insurance and HOA dues are property-specific and are called out separately, not baked into the price math.

Buy the median-priced home in each city with the same assumptions and P&I plus property tax differ by roughly $1,175 a month before insurance and any HOA. Statewide and metro averages hide street-level variation, so the complete monthly payment, including the escrow for taxes and insurance, is the number that matters, and it is always property-specific.

The pair-specific result: an $1,800 monthly P&I-plus-tax budget is a below-median Chicago payment that buys a condo or a compact house, and it is a near-median San Antonio payment that buys a standalone house. Chicago's higher effective property tax rate is part of why the supported price numbers come so close in dollar terms; what actually differs is where that payment sits in each market, and the property type each market's median offers for it. That is where the pre-approval conversation starts: on your real inputs, not example math.

Cash to close: a Chicago transfer tax line that drops

Cash to close is the sum of everything you bring on closing day: down payment, loan fees, title and escrow charges, prepaids, and prorations. The Texas closing costs for buyers and the cash to close breakdown cover what a Texas purchase actually charges; what differs for a Chicago buyer is the transfer tax line on the sell side.

Chicago charges a city real estate transfer tax of $3.75 per $500 of sale price, which is 0.75%, with an additional $1.50 per $500 on the portion above $1.5 million. On the median-priced Chicago home that city tax is roughly $3,200 at closing, and it falls on the buyer. A 2024 ballot measure that would have raised the rate sharply on homes over $1 million was rejected by Chicago voters, so the rates above still stand. Illinois state and Cook County transfer taxes are paid by the seller. Texas has no state transfer tax at all, and the buyer-side cash-to-close shape is different: title policy, recording fees, lender fees, and prepaids, with taxes and insurance prorated at closing.

One more practical difference Chicago buyers notice: Illinois residential closings commonly run through attorneys, while Texas sales are contract-driven and close through a title company escrow, with attorneys available and optional. The change is in who moves the paperwork, not in how much protection you get. The planning step is the same on either end: get the complete cash-to-close number for the specific home, not just the price tag, before you write an offer. First-time buyers can also work the move with FHA at 3.5% down, VA at 0% down where eligible, or USDA at 0% down on eligible addresses, and Texas down payment assistance can cover part of the gap.

The military move: Great Lakes to JBSA

This pairing is mostly a training-pipeline move rather than a mass PCS corridor, and the link is real. Naval Station Great Lakes, about 35 miles north of downtown Chicago, is the Navy's only boot camp, graduating tens of thousands of new sailors a year, and it is a major training hub. When the Navy's Hospital Corps School relocated from Great Lakes to the Medical Education and Training Campus at Fort Sam Houston in 2011, Joint Base San Antonio became a routine next stop for new sailors and corpsmen, and it remains one of the Navy's school destinations. So families in the Great Lakes area do receive orders toward the three main JBSA components: Lackland to the west, Fort Sam Houston to the northeast, and Randolph farther northeast on the I-35 side.

The BAH math is worth seeing even for a training move, because the allowance drops and the housing cost drops with it:

That table is illustrative arithmetic with a stated assumption set, not a promise, and every service member's file differs by rank, dependency status, and the specific home. The honest read: the BAH number drops by more than half between the two areas, but the median home payment drops with it, so the allowance keeps covering about the same share of a median-priced home. The VA loan itself works the same in both states: 0% down, no monthly mortgage insurance, and a one-time funding fee that runs about 2.15% of the loan for first-time use with less than 5% down (about 3.30% for subsequent use), with the fee waived for veterans receiving VA disability compensation. VA financing is a specialty of mine, and the VA loans for JBSA buyers guide and the orders-to-keys PCS guide cover the timing and the paperwork.

Climate: lake-effect winter to a long cooling season

This pairing has the most lopsided winter-to-summer trade in the series. Chicago averages about 35 inches of snow a year; San Antonio averages about 0.2 inches. Chicago's January low is about 22 degrees and its January high about 33; San Antonio's January low is about 40 and its high about 66. The summers trade in the other direction: Chicago's July high is about 86 degrees, while San Antonio's July and August highs run about 94 to 96, and the city crosses 90 degrees on more than 100 days a year. Both cities get real rain, about 38 inches in Chicago and about 33 in San Antonio, but on different calendars: Chicago's wettest stretch is spring through summer, and San Antonio's heaviest rains center on May and early fall.

The everyday costs trade places too. Chicago's winter is the expense: heating, snow removal, and the gear. San Antonio's summer is the expense: a long air conditioning season, higher summer cooling bills, and the occasional hard freeze that Texans now plan for one night a winter. Water is notably cheaper in Chicago, where Lake Michigan supply keeps the bill low; San Antonio's summer irrigation for a Texas yard is a heavier line. None of this is a verdict on either city, it is a wardrobe and budget difference, and the flood zone check at the exact address belongs in every Texas diligence list.

The trip: two days by truck, two hours by air

Chicago to San Antonio is about 1,200 to 1,250 miles by road, most commonly on I-55 into Arkansas and then I-30 and I-35 through the Dallas/Fort Worth area. Nonstop driving time is roughly 18 to 22 hours at freeway speeds, and with stops most families plan it as a two-day trip, which is how moving trucks and a second vehicle usually travel. By air the same trip is about 1,040 miles along the great circle, and nonstop flights between O'Hare or Midway and San Antonio International run about two hours in the air on several carriers (verify current schedules and times).

One quirk that saves planning time: both cities are on Central Time, so there is no time change, which is rare for a move of this distance. This is still a fly-to-visit distance, not a weekend drive: Thanksgiving and summer visits become flight decisions, not tank-and-go decisions. For remote or hybrid workers the move is simpler than it was a decade ago, but the honest planning step is the same as for any distance move: shortlist homes on video, verify financing first, and use the Texas option period plus a local inspection to do the verifying that video cannot.

Chicago habits that travel with the move

A few Chicago assumptions need adjusting on arrival, and they show up more than you might think:

• The weather expectation is the big one. Lake-effect winters are the most cited reason Chicagoans leave, and the honest version of this move is that the trade runs both ways: snow days become 95-degree days, and the long cooling season is San Antonio's version of Chicago's heating season. Plan the move for spring or fall if you can, and budget for the AC load.
• The sticker rate on a tax bill means nothing across state lines. Chicagoans learn to ignore the nominal ~7% rate on their Cook County bill and focus on the effective ~2%. In San Antonio the rate on the bill is close to what you pay, so do not panic at the 2.27% combined rate; compare the dollar bill, which usually runs about half for a median home.
• The transfer tax line disappears. Chicago's buyer-paid city transfer tax is a real closing line, about $3,200 on a median-priced home. Texas has no state transfer tax, so the cash-to-close shape changes: lower transfer fees, different title and escrow structure. Run both numbers for the exact property.
• The condo-to-house transition is common. Chicago's city median blends a heavy share of condos and two-flats. In San Antonio the median is a house with a lot, so budget for first-time upkeep: roof, air conditioning, irrigation, foundation notes at inspection, and the weekend yard that a condo association used to handle.
• The transit habit changes fast. Thousands of Chicagoans live with one car or none, riding the CTA and walking the neighborhood. San Antonio is a driving city, and the honest planning step is to test the commute and count the cars before you commit to a corridor.
• The retirement income math is a tie, not a win. Illinois exempts retirement income and Texas taxes no income at all, so empty-nesters give up less on the income tax line than working families. The property tax dollar savings and the sales tax drop are what make the retirement version of this move.
• The lake changes shape. Lake Michigan is Chicago's defining water. San Antonio's answers are Canyon Lake, the Guadalupe and Comal rivers, and the Hill Country lakes, all within a drive of the city, and each with its own lot, utility, and zoning rules to check by address.
• The airport math changes. O'Hare and Midway together are among the busiest airport systems in the country, with global routes from nearly every carrier. San Antonio International is smaller with solid domestic coverage, and Austin's airport adds a second option about 75 miles up I-35 when the schedule demands it. Check the flight maps for the routes you actually fly before you assume the new airport covers it.

Where you land in San Antonio

Chicago transplants land all over the San Antonio area, and the honest answer is that the right corridor depends on your commute, your budget, and the property type you want. This market splits into a few corridors, each with a full guide in our community library:

• I-35 northeast, Schertz, Cibolo, and New Braunfels: town and suburban homes with city services, the fastest-growing family corridor in the area and a short highway hop to downtown and Randolph, which makes it the default for military families. New Braunfels guide.
• US-281 north, Bulverde and Spring Branch: larger lots and Hill Country terrain, with much of the corridor unincorporated, so wells, septic, and utility districts are common. Bulverde guide.
• I-10 west, Boerne and Fair Oaks Ranch: a town with its own services plus master-planned communities that cross Kendall, Bexar, and Comal County lines. Boerne guide.
• Canyon Lake: lake-country acreage and resort-style communities in unincorporated Comal County, quiet and spread out rather than walkable. Canyon Lake guide.

Chicago buyers also notice one thing a condo-heavy city market rarely offers: choices with meaningful lot sizes at a fraction of the Chicago price per home. Each corridor carries its own county, school district, appraisal district, utility mix, and tax jurisdictions, so the comparison is never "metro versus metro" but "exact address versus exact address." The relocation hub compares all the corridors on the complete monthly payment without declaring a universal winner, because there is not one.
