New Construction or an Older Home in Round Rock: Which Is the Better Bet?

When people in Round Rock ask me whether new construction is a better bet than an older home, I give the same answer each time. Neither one wins for every buyer. I'm Ai Tran, and I help buyers across Round Rock and the towns around it compare real houses, not ideas about houses. A brand new home and a home built decades ago can both be a smart purchase, and both can turn into a strain if you only look at the asking price.

The better bet is the home whose full yearly cost and daily life you understand before you commit. This post walks through what I compare when a buyer is torn between a builder's model home and an older house on a finished street.

Builders have been active around Central Texas, and the numbers reflect it. Figures shared at the Austin Board of Realtors' annual Central Texas Housing Summit, as reported by Yahoo Finance, showed builders' asking prices falling from roughly $500,000 in 2023 to $387,240, while resale asking prices moved from $519,900 to $499,999.

Those figures are useful, but they do not prove that the same house costs less when it is new. An average asking price reflects where builders are working, how big their homes are and how large their lots are. A new home on the edge of town and an older home near downtown Round Rock are different products, so I always compare them on size, location, lot and yearly cost, side by side.

Property taxes in Texas come from several taxing units stacked together, and the stack can look very different from one street to the next. The City of Round Rock reports an adopted rate of 37.2 cents per $100 of assessed value for fiscal year 2025-2026. That city rate is only one line on the bill.

Many newer subdivisions also sit inside a municipal utility district, or MUD. The Houston Chronicle explains that a MUD gives a developer another way to pay for water, sewer, drainage and roads. Community Impact reported that the Round Rock City Council approved a 900-unit MUD near the Round Rock and Georgetown border in June 2025, and that its residents will pay taxes to both the district and the city, similar to Salerno and Homestead at Old Settlers Park.

A MUD is not automatically a bad thing, because it is how much of the new infrastructure gets built. It does mean that two homes with the same price can carry very different yearly costs. Older areas are not always free of a MUD either, since LRG Realty describes Brushy Creek as centered around the Brushy Creek Municipal Utility District. I look up every taxing unit for the exact address before a buyer falls in love with a house.

A new home gives you rooms nobody has lived in, a layout designed for how people live today and major systems that start their life on the day you move in. Zillow lists builders such as Highland Homes, Lennar and Brohn Homes working in Round Rock, and Century Communities is building at Avery Centre in the 78665 ZIP code. Each builder uses its own floor plans, materials and standard features, so two new homes in the same price range can be built quite differently.

The warranty deserves a careful read. According to the Holmes Firm, a Texas construction law practice, the Texas Residential Construction Commission was abolished and builders have not been required to provide statutory warranties since 2010. Many builders still offer a written warranty, and that document sets what is covered and for how long, so I ask to read it early.

New construction also comes with tradeoffs you can see if you look for them:

• Young trees will take years to give real shade in the Texas summer.
• Empty lots nearby may become more homes, roads or commercial buildings.
• The finished price can climb as you add upgrades to the base plan.
• Construction traffic and noise may continue while later phases are built.

I also suggest an independent inspection on a new home, ideally before the walls are closed, because a new house can still have mistakes that no one has caught yet.

An older home gives you a finished street, and you can see exactly what surrounds it. Civitas Senior Living describes Forest Creek as an established neighborhood with mature oak trees and a golf course, and LRG Realty describes Brushy Creek as one of Round Rock's oldest and most established neighborhoods, with mature trees and larger lots. A finished street gives you shade, settled landscaping and neighbors' homes that are already built, so very little about the view out your window will change after you move in.

The tradeoff is age. The roof, the air conditioning system, the water heater, the windows and the plumbing all have a working life, and some of them may be near the end of it. That does not make an older home a bad bet. It means the real price of the home includes whatever needs replacing over the next several years. When I tour an older house with a buyer, I want to know the age of every major system, and I want an inspection to tell us what the eye cannot see.

Many older homes also need updating to match how you want to live. Some buyers enjoy that work, and some would rather move in and change nothing. You know which kind of buyer you are, and the answer should shape your search.

When a buyer is stuck between new and older, I bring the decision back to a few plain questions:

• What will this home cost each year? I add up every taxing unit, including any MUD, plus any homeowners association dues. LRG Realty reports HOA fees of $50 to $200 a month in master-planned Round Rock communities such as Teravista, Paloma Lake and Siena.
• What will need money in the next five years? On an older home, I look at the systems. On a new home, I look at the upgrades and the landscaping you will still have to finish.
• What is planned around the lot? On a new street, I check what the empty land nearby is zoned or planned for.
• How does the daily drive feel? Newer communities often sit farther from the center of town, so I suggest driving the route at the hours you would really travel.

If the best new homes for your budget are just outside the city, I can compare them with options in Georgetown and Hutto as well. You can also read my overview of Round Rock before we start.

Whether the home is new or older, the first step is the same. You need a real number that the loan will support, based on your actual income, including 1099 income if you are self-employed. With that number in hand, you can compare a builder's home and an older house fairly, because you know which ones truly fit.

Many of the buyers I work with decide slowly and together, often with parents who would rather hear the details in Vietnamese. I am glad to explain each step in English or Vietnamese, at the pace your household needs. You can see how I work on my process page and browse current homes on my listings page.
