Most DFW homeowners should get a professional value check at least once a year, ideally in April when the appraisal district mails notices, and again any time a major decision is coming: selling, refinancing, renovating, insuring, or estate planning. If you plan to sell within 12 months, check every quarter, because local prices move within a single year.
Here is why that cadence makes sense. According to the North Texas Real Estate Information Systems (NTREIS) MLS Summary Reports published by MetroTex, the median sales price for single family homes in the Dallas-Fort Worth-Arlington metro was $385,000 in January 2026, rose to $405,000 in June 2026, then eased to $400,000 in July, $390,000 in August, and $385,000 in September 2026 (see the September 2026 report). That is a $20,000 swing in the metro median within one calendar year, and individual neighborhoods and price ranges can move more or less than the metro as a whole.
Why does home value change so much within a year in DFW?
A metro median is a blend of very different markets, and the blend shifts with the season. In the same NTREIS reports, the Dallas County single family median was $370,000 in July 2026 and $360,000 in September 2026, while the Collin County median was $466,500 in July and $447,000 in September. Supply also matters: months of inventory for single family homes in the metro stood at 3.5 in January 2026 and 4.3 in September 2026, which means buyers had more homes to choose from by fall.
Your own home's value depends on a narrower set of facts than any of those numbers:
- The last six to twelve months of closed sales on your street and in your subdivision.
- How many competing homes are active right now in your price range.
- Your lot, condition, updates, and floor plan compared with those sales.
- Days on market for homes like yours, which signals how much pricing power sellers have.
Because those inputs change month to month, a value that was right last spring may not be right today.
When should I check my home's value?
Once a year, when the appraisal notice arrives
In Texas, the most useful annual check lines up with the property tax calendar. The Dallas Central Appraisal District mailed 2026 notices of appraised value for residential and commercial real property on April 14, 2026, with a protest deadline of May 15, 2026. Under Texas Tax Code Section 41.44, the protest deadline is May 15 or the 30th day after the notice was delivered, whichever is later. Collin, Denton, and Tarrant appraisal districts follow the same statute, so check the date on your own notice.
Reviewing your market value in April gives you two things at once: a sense of your equity, and a basis for deciding whether the appraisal district's number deserves a protest. For a walkthrough of the notice itself, see what to check on your Dallas County property tax bill.
Before any major financial decision
Get a fresh, written value before you:
- List the home for sale.
- Refinance or open a home equity line.
- Start a renovation large enough to change what the home could sell for.
- Update homeowners insurance coverage.
- Update an estate plan, divorce settlement, or trust funding.
- Buy your next home with a contingency on selling this one.
Every quarter if you might sell within a year
If a move is likely in the next 12 months, a quarterly check lets you watch your price range rather than the metro. The 2026 NTREIS figures above show how much can change between a spring estimate and a fall listing date. Our guide to whether to sell your Dallas home in the fall or wait for spring covers timing in more depth.
What kind of value check do I need?
Different questions call for different tools. The main options are:
- Online estimate. Free and instant, but built from public records and broad models. Useful as a rough signal, not a pricing decision. We explain the limits in how accurate online home value estimates are for Dallas homes.
- Comparative market analysis (CMA). Prepared by a licensed agent using recent closed, pending, and active listings, adjusted for your home's features. This is the standard tool for a listing decision or an annual review.
- Appraisal. Prepared by a licensed appraiser, typically ordered by a lender, and required for most financing. Also useful for estate and legal matters.
- Appraisal district value. The number on your notice, used to calculate property taxes. It is a mass appraisal and may not reflect your home's specific condition.
The differences matter, so we wrote a separate guide on the difference between a CMA, a broker price opinion, and an appraisal in Texas.
Does my tax value tell me what my home is worth?
Not reliably, especially for homesteads. Texas Tax Code Section 23.23 limits the increase in a residence homestead's appraised value to 10 percent over the prior year's appraised value, plus the value of new improvements. That means the taxable appraised value on a long held homestead can sit well below what the home would sell for. The notice also shows a market value, which is closer, but it is set as of January 1 and based on mass appraisal methods rather than a walkthrough of your home.
Treat the appraisal notice as one data point, and compare it with recent sales near you before you decide either to protest or to price a listing.
How do I check my home's value myself between professional reviews?
You can keep a rough watch on your own value in a few minutes a month:
- Track closed sales within your subdivision or a half mile radius, and note price per square foot.
- Watch how long active listings near you are sitting, and whether they cut prices.
- Read the monthly county market reports for your area, such as our Dallas County housing market report or the broader DFW housing market report.
- Keep a list of improvements with dates and costs, because those are the details a CMA needs.
Self tracking will not replace a professional opinion, but it will tell you when something has changed enough to ask for one.
How does The Agency Dallas approach home valuation?
Our agents prepare valuations across North Texas, from Dallas and Highland Park to Collin and Denton counties and rural acreage through our statewide Land and Ranch Division. A home valuation from The Agency Dallas is a written CMA built on recent closed sales near your property, with the adjustments explained, rather than a single automated number. The Agency Dallas treats a home value review as a planning tool, so it is just as useful for an owner who is staying put as for one getting ready to list.
If your 2026 appraisal notice raised a question, or you are thinking about a move next spring, our agents can prepare a written comparative market analysis for your address with the comparable sales and adjustments laid out, so you have a dated number to measure against next April.
Frequently asked questions
How often should I check my home's value if I am not planning to sell?
Once a year is enough for most owners who are staying put. The best time is April, when appraisal notices arrive, because you can compare the district's number with recent sales and decide whether to protest. Add an extra check before refinancing, a large renovation, an insurance update, or estate planning, since each of those decisions depends on a current value.
Are online home value estimates accurate in Dallas-Fort Worth?
Online estimates are a reasonable starting point but can miss by a meaningful amount, especially for homes with recent updates, unusual lots, or few nearby comparable sales. They rely on public records and broad models rather than a look at the home. Use them as a signal to watch, and rely on a written comparative market analysis or an appraisal for any real decision.
When is the property tax protest deadline in Dallas County?
Under Texas Tax Code Section 41.44, the deadline is May 15 or 30 days after the notice was delivered, whichever is later. For 2026, the Dallas Central Appraisal District mailed residential notices on April 14 and listed a May 15, 2026 protest deadline. Always check the date printed on your own notice, since delivery dates vary.
Why is my appraisal district value lower than what my home would sell for?
If your home has a homestead exemption, Texas Tax Code Section 23.23 limits the yearly increase in its appraised value to 10 percent plus new improvements. Over several years of rising prices, the capped value can fall well below market value. The market value on the notice is also a mass appraisal set as of January 1, not a property specific opinion.
How much did DFW home prices change in 2026?
According to NTREIS MLS Summary Reports, the single family median sales price in the Dallas-Fort Worth-Arlington metro was $385,000 in January 2026, peaked at $405,000 in June, and returned to $385,000 by September. Year over year changes in those months ranged from roughly flat to down 1 percent. Your neighborhood and price range may have moved differently.
