What Your First Month of Owning a Home in Round Rock Really Costs

When you buy a home, it is easy to focus on one number, the monthly payment. Then the keys arrive, and several smaller costs show up in the same few weeks. None of them needs to be a surprise once you know the list. I'm Ai Tran, and I would rather you see that list now, while there is still time to plan, than meet it in your mailbox.

This guide walks through what tends to land in the first 30 days of owning a home in Round Rock, what arrives later in the year, and how to build your own estimate. I only include figures I could trace to a public source, and I name the source each time. Your own numbers will depend on the house, the street, and the choices you make.

If the home is inside the City of Round Rock's service area, your water, wastewater, stormwater, garbage, and recycling service comes from the city. The city says these services are billed together each month through its Utility Billing Office, and its current rate page lists garbage and recycling at $25.51. Water and wastewater charges depend on how much you use, so your first real bill will tell you more than any estimate can.

Timing matters here. The City of Round Rock notes that customers can view their usage after the first bill is generated, which is typically about 30 days after water service is connected. That means your first water bill often arrives near the end of your first month or just after it. When you apply for new service, ask the Utility Billing Office whether a deposit or connection fee applies to your account. The city also says its representatives will never contact customers directly to ask for payment by phone or in person, so treat any call like that as a scam.

Some neighborhoods around Round Rock sit inside a municipal utility district. The Meadows at Chandler Creek MUD, for example, says on its website that the City of Round Rock handles billing, connections, and disconnections for its residents. If the home you want is in a district, ask how service and billing work there before you move in.

Electricity works differently. Round Rock is in Oncor's delivery territory, according to Choose Energy, though part of the Round Rock area is served by Pedernales Electric Cooperative. In Oncor territory, Oncor maintains the lines and meters, and you choose a retail provider and a plan. Read each plan's fact sheet before you sign, because the price per kilowatt hour can change with how much power you use. It is also worth confirming which utility serves your exact address.

Internet is the last piece. If you work from home, schedule installation a week or two before move-in day so you are not waiting on an open appointment.

Most buyers line up a homeowners policy before they get the keys, so this cost begins right away. Texas premiums have been rising. CNBC Select, citing the Texas Department of Insurance, reported that the average Texas homeowner paid $3,489 for coverage in 2025, or about $290 a month, up from an average of $3,291 in 2024.

Your premium may land well above or below that average. The age of the roof, the deductible, your coverage limits, and your claims history all play a part. Get quotes from more than one company, and ask whether wind and hail damage carry their own deductible, because that number matters a lot in Central Texas storm season.

Property taxes in Texas do not show up as a monthly bill from the city. The City of Round Rock says property taxes are billed in October each year and do not become delinquent until February 1 of the following year. Even so, your first month is the right time to understand what that bill will look like.

For fiscal year 2025 to 2026, the City of Round Rock adopted a tax rate of 37.2 cents per $100 of assessed value. The city puts the median home value on its 2025 tax rolls at $395,240 and estimates the city tax bill for that home at $1,470. That figure is the city's portion only. Your full bill also includes other taxing units, such as the school district and the county, so the total will be higher.

Ask your lender how property taxes and insurance are handled in your monthly payment, and plan around that answer. A clear picture now is far easier than a surprise in October.

One of the most useful things you can do in your first month takes only a little paperwork. If the home is your primary residence, you can apply for a residence homestead exemption. State law requires school districts to provide a $140,000 exemption on a residence homestead.

In Williamson County, you file with the Williamson Central Appraisal District. WCAD says you can apply online by finding your property in its Property Search and selecting the HS Exemption icon. Before you apply, check WCAD's site for the documents it asks you to provide. If you buy outside Williamson County, you file with that county's appraisal district instead.

These costs are small one at a time, but they add up quickly in the first few weeks:

• Rekeying the exterior locks gives you control over who has a key to your home.
• Fresh air filters and smoke detector batteries let you start with a known baseline instead of guessing when they were last changed.
• Yard care means a mower and hose or a lawn service, and an HOA may have rules about how the yard looks.
• Window coverings are an expense when a home comes without blinds or curtains.
• Basic tools, such as a ladder, a drill, and cleaning supplies, tend to get bought in the first weekend.
• Small repairs often appear once you are living in the house, like a running toilet or a sticky door.

If the home has a homeowners association, ask for the dues amount and the payment schedule in writing. Some associations bill monthly, and others bill quarterly or once a year, so your first HOA bill may be larger than you expect.

Moving also leaves behind old furniture and large items. Round Rock offers eligible residents one free bulk pickup per year, scheduled through Republic Services. That pickup can save you a hauling trip after the move.

A real estimate beats a rule of thumb. Here is the simple worksheet I suggest:

• Start with the monthly payment your lender quotes you.
• Add your actual homeowners insurance cost per month, based on the quotes you collected.
• Add electricity, water, garbage, and internet, using the plan you chose and the city's published rates.
• Add HOA dues if the home has them, adjusted to the schedule the association uses.
• Set a one-time move-in budget for locks, filters, yard tools, window coverings, and small repairs.
• Put a reminder on your calendar to file your homestead exemption with the appraisal district.

I walk through this worksheet as part of my home buying process, before anyone starts touring houses. If you are still deciding where to look, my Round Rock area guide covers the city in more detail, and you can browse current homes on my listings page.
