Buying in Round Rock vs. Pflugerville: The Mortgage Math
If you are shopping the northern Austin suburbs in 2026, two names come up again and again: Round Rock and Pflugerville. They sit minutes apart, both pull commuters toward downtown Austin and the tech corridor, and both market themselves on schools and value. The mortgage math behind them is not identical. Round Rock sits in Williamson County and Pflugerville straddles mostly Travis County, and that single line on a map changes your property tax bill, your monthly payment, and how much house your income will actually support.
The Austin-area median sold price was $473,745 the week of June 17, 2026 (Team Price Real Estate, Austin-Area MLS data), with roughly six months of supply. That balance gives buyers in both suburbs more room to negotiate than they had a few years ago. The question is where your dollar stretches further once taxes and insurance land in the escrow column.
Key points:
- Round Rock is in Williamson County; most of Pflugerville is in Travis County, so your property tax rate and exemptions follow the county and school district, not just the city.
- Effective property tax rates in the Austin metro generally run between about 1.8% and 2.3% of assessed value, and that 0.2% to 0.4% swing can move your monthly payment by $80 to $160 on a $475,000 home.
- Texas raised the homestead exemption to $140,000 for school district taxes in 2026, which softens the tax bill in both suburbs once you file.
- Round Rock ISD and Pflugerville ISD set their own tax rates, so compare the full rate stack (county, city, school, MUD) on the exact address, not the suburb.
- Conventional, FHA, and VA loans all work in both cities; the payment difference usually comes from taxes and insurance, not the loan type.
- Always pull the current rate from the county appraisal district before you write an offer, because rates reset annually.
How much does the county line really change your payment?
The county line is the biggest hidden variable between Round Rock and Pflugerville. Your principal and interest depend on your rate and loan amount, which are the same regardless of address. Property taxes are not. A home assessed at $475,000 taxed at an effective 2.0% rate carries about $9,500 a year, or roughly $790 a month into escrow. Move that same home to a rate of 2.2% and the annual bill climbs to about $10,450, near $870 a month. That $80 difference compounds over a 30-year loan.
Williamson County (Round Rock) and Travis County (Pflugerville) each set their own rate, and on top of that you layer city, school district, and any municipal utility district (MUD) levy. Two homes at the same price can carry different bills if one sits inside a MUD and the other does not. At Mortgage Austin we run the actual escrow numbers on the specific address before you fall in love with a house, so the payment you see in your pre-approval is the payment you live with.
Round Rock vs. Pflugerville: the side-by-side
Here is how the two suburbs compare on the factors that shape a mortgage payment. Treat the tax figures as approximate ranges; the appraisal district publishes the exact rate for each parcel every fall.
| Factor | Round Rock | Pflugerville |
|---|---|---|
| County | Williamson | Travis (small parts in Williamson) |
| School district | Round Rock ISD (some Leander ISD) | Pflugerville ISD |
| Typical effective tax rate | ~2.0% to 2.3% | ~1.9% to 2.2% |
| MUD presence | Common in newer subdivisions | Common in newer subdivisions |
| Commute to downtown Austin | ~25 to 35 min via I-35 / toll 45 | ~20 to 30 min via SH 130 / Mopac |
| Loan types available | Conventional, FHA, VA | Conventional, FHA, VA |
Neither suburb is the universal winner. Round Rock often draws buyers who want the established Round Rock ISD footprint and quick access to the Dell and tech employers along the I-35 corridor. Pflugerville tends to attract buyers who commute via the SH 130 toll or value newer construction at a slightly lower entry price. The right answer depends on your address, your school priorities, and how the tax stack lands on the home you actually want.
Which suburb is cheaper to buy in?
On a pure sticker-price basis, Pflugerville has historically carried a slightly lower median than Round Rock, though the gap narrows on newer construction and varies block to block. Sticker price is only half the story. A home that costs $10,000 less but sits in a higher MUD-plus-school tax bracket can cost more per month than the pricier home next door. Run the all-in payment, not the list price.
The down payment requirement is the same in both cities because it is tied to the loan program, not the location. Conventional loans start at 3% down for qualified buyers, FHA at 3.5%, and VA at zero down for eligible veterans. Where your county shows up is in the escrow line: higher taxes mean a larger monthly escrow cushion and a slightly larger amount of cash you need to set up that account at closing.
Do MUD districts change the math in these suburbs?
Yes, and many newer subdivisions in both Round Rock and Pflugerville sit inside a municipal utility district. A MUD is a special taxing entity that funds water, sewer, and drainage infrastructure for newer developments, and it adds its own rate on top of county, city, and school taxes. A MUD levy can add anywhere from a few tenths of a percent to over a full percent in the early years, then decline as the district pays down its bonds. Two homes a mile apart can carry very different MUD rates, so confirm the MUD status on the specific parcel before you commit.
What loan type works best out here?
For most buyers in Round Rock and Pflugerville, a conventional loan offers the cleanest path: competitive rates, the option to remove private mortgage insurance (PMI) once you reach 20% equity, and flexible down payments from 3% up. FHA can be the better fit if your credit is still rebuilding, and VA is the strongest option for eligible veterans because it skips the down payment and the monthly mortgage insurance entirely. Anthony at Mortgage Austin originates Conventional, VA, and FHA loans, which covers the large majority of buyers in these two suburbs.

Frequently Asked Questions
Is Round Rock or Pflugerville cheaper to buy a home in?
Pflugerville has historically carried a slightly lower median sold price than Round Rock, but the gap is narrow and varies by subdivision and construction age. The bigger cost difference often comes from property taxes and MUD levies on the specific address, not the list price. Compare the all-in monthly payment, not just the sticker.
Why are property taxes different between the two suburbs?
Round Rock sits in Williamson County and Pflugerville is mostly in Travis County, and each county, city, and school district sets its own tax rate. Newer subdivisions in both cities may also sit inside a MUD, which adds another levy. Effective rates in the metro generally run about 1.8% to 2.3% of assessed value.
Does the homestead exemption help in Round Rock and Pflugerville?
Yes. Texas raised the homestead exemption to $140,000 for school district taxes in 2026, and homeowners 65 or older or with a disability qualify for an even larger exemption. You must file the homestead application with the county appraisal district to claim it. The exemption lowers the taxable value, which trims your escrow payment.
Can I use an FHA or VA loan in these suburbs?
Yes. Conventional, FHA, and VA loans all work in Round Rock and Pflugerville. FHA needs 3.5% down with more flexible credit, and VA offers zero down for eligible veterans with no monthly mortgage insurance. The loan type does not change with the city; your taxes and insurance do.
How do I find out if a home is in a MUD?
The seller’s disclosure and the property tax record from the county appraisal district will show whether a MUD levy applies, and Texas law requires a MUD notice for homes inside one. You can also ask your loan officer to pull the full tax rate stack on the address. Confirm this before you write an offer, because the MUD rate affects your monthly escrow.
How much should I budget for the commute difference?
Round Rock commuters typically use I-35 or the 45 toll, running about 25 to 35 minutes to downtown Austin, while Pflugerville often routes via SH 130 or Mopac at roughly 20 to 30 minutes. Toll costs and time vary by your exact start point and work location. Factor tolls and gas into your overall housing budget, since they affect what payment is comfortable.
