If you are trying to make sense of the Castle Hills market, the numbers can feel a little confusing at first. One source says prices are down, another shows listing prices rising, and homes do not seem to be flying off the shelf overnight. The good news is that the data still tells a clear story once you know how to read it. In this guide, you will see what is happening with prices, inventory, timing, and negotiating conditions in Castle Hills, plus what that may mean if you plan to buy or sell. Let’s dive in.
Why Castle Hills trends look different
Castle Hills is a very small community, covering about 2.5 square miles with a population of more than 4,200 residents, and it is made up mostly of private residential property, according to the City of Castle Hills. Because the market is so small, even a few sales or listings can shift monthly percentages in a noticeable way.
That is also why public real estate sites do not always match. Redfin focuses on closed sales, Realtor.com emphasizes active listings and listing trends, and Zillow’s Home Value Index tracks estimated values. They are measuring different parts of the market, so the best approach is to look at all three together instead of expecting identical numbers.
Prices remain high in Castle Hills
Castle Hills continues to stand out as a premium market within the San Antonio area. In February 2026, Redfin reported a median sale price of $475,000 and a median sale price per square foot of $189. That sale price was down 5.0% year over year, while the price per square foot was up 7.4%.
At the same time, Zillow’s March 31, 2026 data put the typical Castle Hills home value at $459,173, down 1.4% from the prior year. Realtor.com’s March 2026 market summary showed a median listing price of $539,000 and $190 per square foot, both up year over year.
So what does that mean in plain English? Sellers are still listing with confidence, but closed-sale pricing and value estimates suggest the market has softened somewhat from prior highs. That does not mean Castle Hills is weak. It means buyers are still paying premium prices, but they may have a bit more room to evaluate value carefully.
Castle Hills is still pricier than San Antonio
If you compare Castle Hills with the broader city, the price gap is clear. Redfin’s data shows Castle Hills at about 1.83 times San Antonio’s median sale price of $259,500. On a price-per-square-foot basis, Castle Hills at $189 is about 23.5% higher than San Antonio’s $153.
That matters if you are buying or selling here. Buyers should expect Castle Hills to trade at a premium relative to much of San Antonio. Sellers should also understand that premium pricing does not remove the need for discipline, especially in a market where buyers can compare options more carefully than they could during the frenzy years.
Inventory is limited, but not frozen
One of the biggest themes in Castle Hills is how little inventory exists at any given time. Realtor.com showed 20 homes for sale in March 2026, while Zillow showed 22 homes for sale as of March 31, 2026. Zillow also reported 7 new listings.
Those are very small numbers. In a market like this, a handful of new listings can quickly make inventory look more competitive, and a handful of accepted contracts can make choices feel tight again. That is why Castle Hills often feels active even when the raw number of available homes is low.
The broader San Antonio market adds context
Looking beyond Castle Hills helps explain current conditions. SABOR reported that San Antonio had 13,680 active listings and 4.64 months of inventory in January 2025, then 17,131 active listings and 6.12 months of inventory in July 2025, before ending December 2025 with 14,441 active listings and 5.25 months of inventory.
In its January 2026 market review, SABOR said 2025 ended with active listings up more than 16% and months of inventory just over five, which it described as near balanced. It also projected measured 2% to 4% price growth in 2026 rather than a return to the intense pace of 2021 and 2022.
That backdrop matters because Castle Hills does not operate in a vacuum. Even though it is a smaller, more expensive pocket, it is still influenced by the wider San Antonio market, where buyers have generally gained more breathing room.
Homes are moving at a measured pace
Castle Hills is not a rush-everything market right now, but it is not stalled either. Redfin showed a median of 131 days on market for sold homes in February 2026. Realtor.com showed 46 days on market for active listings in February 2026.
Those are different metrics, so they should not be compared as if they mean the exact same thing. Still, both suggest a market that is moving at a measured, deliberate pace. Buyers usually have time to think, compare, and negotiate, while sellers should not assume a quick contract just because Castle Hills is a sought-after area.
What negotiation conditions look like
Realtor.com labeled Castle Hills a balanced market in February 2026. By contrast, San Antonio was labeled a buyer’s market, with 13,827 homes for sale, a 99% sale-to-list ratio, and a median of 53 days on market.
SABOR’s December 2025 report adds another useful benchmark. It found that San Antonio homes averaged 92 days on market and sold at 91.2% of original list price. That reinforces a simple point: realistic pricing still matters across the region.
Castle Hills appears to hold a bit more pricing power than the citywide average. Realtor.com’s metrics indicate homes there sold for approximately asking price on average. That suggests well-positioned listings can still perform strongly, even without the extreme bidding pressure seen in earlier market cycles.
What buyers should take from this
If you are shopping in Castle Hills, the main takeaway is balance. You are looking in a premium market with limited inventory, but you are not necessarily competing in a frenzy.
That creates a few advantages for buyers:
- You may have more time to review homes carefully.
- You can compare pricing against recent sold data, not just asking prices.
- You may find room for negotiation when a home is overpriced or has been sitting.
- You still need to move decisively when a well-priced property hits the market, because supply is thin.
This is the kind of market where strategy matters more than speed alone. A smart offer is not just about price. It is also about understanding how the asking price compares with current conditions and how long the home has been available.
What sellers should take from this
If you are thinking about selling in Castle Hills, the data offers a clear message. You can still achieve strong results, but the market is rewarding realistic pricing and strong presentation.
That means sellers should focus on:
- Pricing from current sold comps, not only peak-era expectations
- Preparing the home so it shows well from day one
- Understanding that buyers are comparing options more carefully
- Being ready for a market time that may feel longer than in past years
In a small market, each listing can get plenty of attention, but buyers at this price point tend to be selective. The homes that stand out are usually the ones that enter the market with a thoughtful pricing strategy and a clean, polished presentation.
The bottom line on Castle Hills
Castle Hills looks like a premium, thinly traded market inside the San Antonio metro. Current public data clusters home values and prices in the mid-$400,000s to low-$500,000s, with only about 20 to 22 homes for sale at a time across major public trackers.
The most practical way to read the trend is this: list prices remain fairly firm, closed-sale prices and estimated values are a bit softer, and the overall pace is steady rather than rushed. For buyers, that can mean more opportunity to be selective. For sellers, that can mean strong outcomes when the home is priced with discipline and marketed well.
