The Real Cost of Living in Round Rock Texas

"Cost of living" in Round Rock gets thrown around a lot without actual numbers behind it, so here they are: median home price, the real property tax rate, and how it stacks up against Austin proper. I work with relocation buyers who need this comparison in dollars, not vibes, and this is that version — the actual figures behind housing, taxes, utilities, and insurance rather than a generic "affordable and welcoming" summary.

TLDR: The Real Cost of Living in Round Rock

1. Median home price runs roughly $412K-$430K, compared to $540K-plus in Austin proper — a real gap of $120K or more.
2. The effective combined property tax rate is around 1.8-1.9% of assessed value, slightly above the Williamson County average.
3. Texas has no state income tax, which matters more the higher your household income climbs.
4. Round Rock sits about 5% above the national cost of living index, driven mostly by housing and property taxes, not everyday expenses.
5. Dell's headquarters and the surrounding North Austin corridor mean a real, local job base rather than a purely bedroom-community commute.

Housing: The Real Dollar Gap vs. Austin

The median home price in Round Rock currently runs roughly $412,000 to $430,000, depending on the data source and month. Austin proper's median sits well above $540,000. That's a real gap of $120,000 or more for a comparable home, and it's the single biggest lever in whether Round Rock or Austin makes more sense for your budget. This gap has narrowed and widened over different market cycles, so treat this as a current snapshot to verify against live listings, not a permanent rule.

Property Taxes: The Number That Surprises Relocation Buyers

Property taxes in Round Rock run higher than what many out-of-state buyers are used to. The effective combined rate — city, county, school district, and any special districts — typically lands around 1.8% to 1.9% of assessed value, slightly above the broader Williamson County average, though it varies by specific address and taxing jurisdiction. On a $430,000 home, that's roughly $7,700 to $8,200 a year, and it's worth budgeting on the higher end rather than the lower one until you have an exact number for a specific address. Texas relies more heavily on property tax to fund schools and city services than many states, which is the tradeoff for having no state income tax.

No State Income Tax, and Who That Actually Helps Most

Texas has no state income tax, and that benefit scales with income — it matters more to a household earning $200K than one earning $60K, since the property tax burden is roughly flat by comparison while income tax savings grow with earnings. If you're relocating from a state with meaningful state income tax, run your own numbers rather than assuming the property tax difference automatically cancels it out; for many higher earners, it doesn't come close to canceling out, and Round Rock ends up meaningfully cheaper overall.

Where Round Rock Actually Sits on the National Cost of Living Index

Round Rock runs roughly 5% above the national cost of living average, and that gap is driven almost entirely by housing costs and property taxes — not groceries, healthcare, or everyday goods, which track close to the national average. That's a useful distinction: if you're coming from a high-cost-of-living state, Round Rock's overall index number can look deceptively high relative to your current city, when in reality the gap is concentrated in one category (housing) rather than spread across your whole monthly budget.

Sales Tax and Everyday Spending

Texas caps combined state and local sales tax at 8.25%, and Round Rock sits at that maximum rate. That applies to most retail purchases, though groceries and many essentials are exempt. It's a smaller factor than housing or property tax in your overall cost of living, but worth knowing if you're budgeting a move that includes furnishing a new home.

The Job Market Behind the Numbers

Round Rock isn't just an affordable bedroom community — Dell Technologies is headquartered here, and the surrounding North Austin corridor has a steady base of tech and healthcare employers. That matters for cost of living in a specific way: a shorter commute from Round Rock to a Round Rock-based job saves real money and time compared to commuting in from further out for a similar Austin-based salary. If your job is already based in or near Round Rock, the cost comparison to Austin gets even more favorable once you factor in commute costs and time.

HOA Dues and What They Vary By

HOA costs in Round Rock vary significantly by neighborhood — older, more established communities like Eagle Ridge or Round Rock Ranch typically run lower than newer, amenity-heavy communities like Teravista, which include pools, trails, and clubhouse maintenance in the dues — I've broken these specific neighborhoods down separately in my guide to Round Rock neighborhoods for first-time buyers. Factor the specific HOA into your monthly budget comparison rather than assuming a flat number across the city, since it can meaningfully change the real monthly cost of two similarly priced homes.

Utilities: A Real Line Item, Not an Afterthought

Texas summers push electricity bills up meaningfully from June through September, and Round Rock is on the same ERCOT grid as the rest of the state, which means your bill can vary based on your specific electric plan and rate structure, not just usage. It's worth budgeting for a noticeably higher summer electric bill than whatever you're used to in a milder climate, and shopping electricity plans directly rather than defaulting to whatever provider a builder or previous owner used.

Homeowners Insurance Runs Higher Than Many Buyers Expect

Texas homeowners insurance tends to run above the national average, largely due to hail and wind risk across the state, and Round Rock is no exception. This is a real budget line that's easy to underestimate when you're focused on the mortgage payment — get an actual quote on a specific property before you finalize your monthly budget, rather than assuming your previous state's insurance costs will carry over.

Putting Together Your Own Real Number

The honest way to compare cost of living isn't a single index score — it's your specific mortgage payment at current rates, the actual property tax bill for a specific address, HOA dues if applicable, and your income tax savings if you're coming from a state that has one. I'd rather run these real numbers against two or three specific listings with you than quote a generic city-wide average that may not reflect what you'd actually pay.

Moving Quickly Once You Know Your Number

Live MLS search and my mobile app both give you real-time listing alerts once you know your target price range, rather than a daily digest that lags the market. You can message me directly through the app with a specific address if you want the actual property tax and HOA numbers pulled before you tour it.

How Round Rock Compares to Other Austin Suburbs

Buyers cross-shopping Round Rock often also look at Cedar Park and Leander, and the honest comparison isn't dramatically different on a city-wide basis — all three sit meaningfully below Austin proper on median home price, and property tax rates land in a similar range across Williamson County. The differences that actually matter tend to be commute direction, specific neighborhood amenities, and school district rather than a large citywide cost gap between the three. If Round Rock's specific job access or neighborhood options don't fit, one of the neighboring suburbs is worth comparing directly rather than assuming Round Rock is uniquely affordable among them.

Working With Someone Who Runs the Actual Numbers

I'm Robbie English, Broker, REALTOR at Uncommon Realty, and if you're comparing Round Rock's real cost of living against where you're moving from, I'll pull the actual property tax history, HOA dues, and current market comps on specific listings rather than quoting you a general estimate, so the decision you make is based on your real numbers, not a citywide average that may not apply to the specific home you end up buying.
