Lake Highlands is a good place to buy a house in Dallas if you want a Dallas address with Richardson ISD schools — that is the entire proposition, and it is a strong one. The typical home value in ZIP 75238 was $645,061 as of June 30, 2026, up 1.8% year over year (Zillow Home Value Index). One boundary trap can cost you the whole reason you bought.

Ten days to pending is the fastest market in this batch by a wide margin — Cedar Crest and Kessler Park were both around sixty days over the same period. Well-priced Lake Highlands inventory moves.
But the trend is flat, not hot: Zillow shows +1.8% while RealtyTrac shows -2.6%, and for-sale inventory rose about 89% from August 2025 to July 2026. That is a market normalizing, with more choice for buyers than there has been in years, and it is why speed on a good listing coexists with softness in the aggregate.
Lake Highlands is not one price market, and it is the first thing The Agency Dallas clarifies for anyone asking whether Lake Highlands is a good place to buy a house in Dallas. ZIP 75238 carries a $645,061 index; adjacent 75243 is at $302,101 and 75231 at $301,420. Those ZIPs are frequently marketed as Lake Highlands. The difference is not marginal.
Two sources to reject: Redfin's 75238 page is titled 2026 but serves March 2024 data — confirmed stale. And HAR's neighborhood page 1443 centers on 75218, which is Old Lake Highlands / Casa Linda, a different area with a different school assignment. Both circulate widely.
Where is Lake Highlands?
Bounded roughly by the Richardson and Garland city limits on the north and east, Northwest Highway and White Rock Lake on the south, and White Rock Creek / US-75 on the west. It covers about 14.6 square miles with a population near 99,360 (2023). I-635 and the DART Blue Line both cut through it.
What is the school situation — and what is the trap?
Most of Lake Highlands is Richardson ISD, not Dallas ISD. That is the neighborhood's defining draw: a Dallas address, a Dallas commute, and a suburban district. Fourteen elementary schools serve the area — Aikin, Audelia Creek, Hamilton Park Pacesetter, Forestridge, Forest Lane Academy, Lake Highlands, Merriman Park, Moss Haven, Northlake, Skyview, Stults Road, Thurgood Marshall, Wallace, and White Rock — feeding three junior highs (Lake Highlands, Forest Meadow, Liberty) and Lake Highlands High School.
The trap: Old Lake Highlands — the southern sliver nearest White Rock Lake — is Dallas ISD, feeding Hexter Elementary → Robert T. Hill Middle → Bryan Adams High School. Listings in that sliver are marketed as Lake Highlands, and buyers assume Richardson ISD. Verify the address with Richardson ISD in writing during the option period. If Richardson ISD is why you are buying, this is the only diligence item that can invalidate the entire purchase.
TEA 2024-25 accountability cycle: Richardson ISD as a district rated C (79); Lake Highlands High School rated B (82); Lake Highlands Elementary rated A (92) — the only campus in the area to earn an A that cycle. LHHS enrolls 2,881 students, 56.4% economically disadvantaged.
The 2026 cycle was released August 14, 2026, with Richardson ISD projected to move from C to B (roughly 82). Campus-level 2026 grades are not yet published, so any 2026 letter grade quoted for an individual Lake Highlands campus is not yet verifiable. The 2024-25 ratings above are the current confirmable set.
What about the DART station and Lake Highlands Town Center?
The Lake Highlands DART Blue Line station opened December 6, 2010 as DART's first infill station, following a TIF district created in 2005; the Town Center itself opened in 2014.
The honest footnote: that station averages 364 weekday boardings — the lowest of any station on the Blue Line (DART Reference Book v16.0, May 2025). Transit is present and available; it is not how most of Lake Highlands actually commutes. Buy the house for the schools and the location, and treat rail access as a bonus rather than the plan.
How does Lake Highlands compare on value?
The cleanest comparison in this batch: ZIP 75214 (Lakewood) carries a Zillow index of $852,676 against 75238's $645,061 — a gap of roughly $207,000, or about 24% (Zillow, June 30, 2026).
For that $207,000 difference, Lakewood gives you a top-ranked elementary, period revival architecture, a conservation district, and White Rock Lake at the end of the street — alongside a middle school that rated D in 2024-25. Lake Highlands gives you a consistent K–12 Richardson ISD pattern, more square footage per dollar, and 1960s stock instead of 1920s stock.
That is the trade The Agency Dallas puts in front of every buyer weighing whether Lake Highlands is a good place to buy a house in Dallas: you are buying a school district and square footage rather than architecture and a lake.
Who should buy in Lake Highlands?
Good fit:
- Families who want Richardson ISD without moving to the suburbs
- Buyers who want more house per dollar than Lakewood, Bluffview, or Preston Hollow deliver
- Anyone who wants a normalizing market — inventory is up roughly 89% year over year
Look elsewhere if:
- You want period architecture; average year built is 1965 and the stock is mid-century ranch
- You are buying in the Old Lake Highlands sliver expecting Richardson ISD — verify first
- You are relying on the DART station as your primary commute
