If you've typed "how much is my house worth" into Google at any point recently, you're not alone. It's one of the most searched real estate questions in Texas — and the answer is more nuanced than any website will tell you. Home value isn't a single number you look up. It's a conclusion you reach by weighing several factors against current market conditions. Here's how to think through it the right way.
Comparable Sales Are the Foundation — Here's How to Find Them Yourself
The most reliable measure of market value is what similar homes nearby have actually sold for in the past 60 to 90 days. These are called comparable sales, or comps. Buyers and their agents use them. Lenders use them for appraisals. Sellers should use them too.
You have two practical ways to pull comps yourself before talking to an agent:
Your county appraisal district website. Every Texas county has a public-facing CAD portal. In DFW, that means DCAD (Dallas), TCAD (Tarrant), CCAD (Collin), or DCAD (Denton), depending on where your home sits. Search your neighborhood, filter by recent sales, and look at homes within roughly 0.5 miles with similar square footage, bed/bath count, and age. The data is sourced from deed records, so the sales prices are real — not estimates.
Zillow's sold listings filter. Go to Zillow, switch to "Sold" mode, and draw a boundary around your neighborhood. Filter by beds, baths, and square footage close to yours. You're not using Zillow's estimate here — you're reading actual closed sales. That's a meaningful distinction.
Neither source gives you the full picture on condition or upgrades, but they give you a realistic price range to anchor your thinking.
Your CAD Assessed Value Is Not Your Market Value
This is one of the most common misconceptions among Texas homeowners. The appraised value on your property tax notice from the county appraisal district is a tax assessment — it is not what your home would sell for today.
Texas CADs are required to assess properties at 100% of market value, but in practice, assessed values lag behind real transaction prices — sometimes significantly. During rapid appreciation cycles like DFW experienced in 2021 and 2022, your home might have sold for 20% to 30% above what the CAD had on the books. In a cooling market, the relationship can flip.
Using your tax assessment as a listing price anchor will either leave money on the table or cause you to overprice and sit. Neither outcome serves you.
What a Comparative Market Analysis Actually Looks Like
A comparative market analysis, or CMA, is the tool a licensed agent uses to estimate your home's market value before you list. It goes beyond a simple comp pull. A well-prepared CMA includes:
- Sold comps from the past 60 to 90 days, adjusted for differences in size, condition, lot, and features
- Active listings that represent your competition right now — buyers are comparing your home to these simultaneously
- Pending sales that signal where the market is heading
- Expired and withdrawn listings that show you price points the market rejected
- Days on market trends for your specific zip code or subdivision
The adjustments matter. If your home has a three-car garage and the closest comp has a two-car, an agent familiar with your submarket knows roughly what that difference is worth to buyers in that area. That kind of local calibration is what separates a CMA from a raw data pull.
At EXL Realty Group, our agents prepare CMAs specifically for DFW submarkets — not a generic algorithm applied to your address.
Online Estimates: Useful Starting Point, Not a Final Answer
Zillow's Zestimate and Redfin's Estimate are the two most commonly referenced automated valuations in DFW. They're publicly available, instant, and directionally useful. They are not accurate enough to make a listing decision.
In dense urban areas with high transaction volume and uniform housing stock, these tools can get within 3% to 5% of actual sale price. In DFW's more varied suburban landscape — where you have custom builds next to production homes, large lot variances, and rapidly changing demand by school district — the error range commonly runs 5% to 15% in either direction.
A 10% error on a $450,000 home is $45,000. That's not a rounding problem. It's a material number that affects your net proceeds, your timeline, and whether your deal appraises.
Use the online estimate to orient yourself. Then verify it with real comps and, when you're ready to decide, a CMA from a local agent.
The Micro-Factors That Move Value in DFW
Two homes on the same street, same square footage, same year built — and they sell for different amounts. This happens constantly in DFW, and it comes down to micro-factors that no algorithm weights well:
School district. In North Texas especially, school district boundaries drive meaningful price premiums. A home that feeds into a highly rated Frisco ISD or Carroll ISD school commands more than a comparable home in a lower-rated district, even within the same city.
HOA presence and quality. A well-managed HOA with enforced deed restrictions typically supports values. A poorly managed or financially troubled HOA can suppress them. Buyers research this.
Lot characteristics. Backing to a busy road, backing to power lines, a pie-shaped lot that limits usable yard — these create consistent discounts, typically 3% to 8% depending on severity. Conversely, a greenbelt or water view can add meaningful value above comparable sales.
Condition and updates. A kitchen remodel or updated primary bath in line with current buyer preferences adds value. Outdated finishes or deferred maintenance creates an expectation of a discount, even if the bones of the house are solid.
The Most Reliable Number Comes From a Local Agent
Online tools give you a range. County records give you raw data. A CMA from an agent who knows your specific neighborhood gives you a defensible number you can actually act on — one that accounts for current competition, recent buyer behavior, and the specific features of your home.
If you're preparing to sell in the DFW area and want to know what your home is genuinely worth in today's market, the right next step is a free home value estimate from an agent who works your submarket regularly.
