We mapped the off-market share of Dallas ZIP by ZIP — how much of each neighborhood sells without ever reaching a public listing. The study lays out the three big findings. This post does the other half of the job: it sets the 8 ZIPs side by side and reads the differences between them.
Batch 1 is these eight, top to bottom by off-market share:
Every ZIP is on the interactive map — lit with its off-market share.
Explore every ZIP on the mapWhat all 8 share
Every ZIP in this batch clears 39%. Off-market never drops below roughly two in five sales, and in half these ZIPs it's the majority of the market. The floor is high everywhere — rich, working-class, and in between. This is the batch's one flat truth: in Dallas, the quiet market is not a niche. It's half the board.
A 30-point spread from the lowest ZIP to the highest. Same city, same five years, same measurement — and the neighborhoods sit that far apart.
Where the 8 split apart
Highland Park sits alone at the top
75205 hits 69% — the highest in the batch by 12 points, and the most expensive ZIP in it. The wealthiest neighborhood is also the quietest one. Money doesn't list more; it sells more of its homes before anything reaches a public feed.
Affluence doesn't set the rate
Compare the two affluent ZIPs in the batch: Highland Park at 69% and North Dallas (75230) at 51%. Both are money. They land 18 points apart. Value tells you nothing reliable about how quiet a ZIP runs — 75230 sits closer to working-class Oak Cliff than to its Park Cities neighbor. The off-market habit is a neighborhood trait, not a price bracket.
Same rate, opposite neighborhoods
Greenville / M Streets (75206) and West Oak Cliff (75211) both land at exactly 57% — an inner-loop mid-market ZIP and a working-class Oak Cliff ZIP, identical off-market share. The number alone would tell you they're the same market. They are not. Which is the point of the next split.
The east side is the floor
Lakewood (75214) at 40% and East Dallas (75228) at 39% anchor the bottom of the batch — the two close-in east-side ZIPs, back to back. Off-market is still four in ten sales here. "Lowest in the batch" still means nearly half the market trades where the listings can't show it.
The rate is universal. The buyers aren't.
The off-market rate is half of what separates these ZIPs. The other half is who's buying. Across the batch, investor and LLC buyers take roughly twice the share of sales in the cheaper ZIPs that they do in the affluent ones. Two ZIPs can post the same off-market number — 75206 and 75211 both at 57% — while one is a quiet-luxury resale market and the other is an investor market. A single "Dallas off-market" average would describe neither.
That is the case for reading a ZIP as a ZIP. The off-market opportunity is everywhere in this batch. Its shape — who buys, who sells, at what price — is local, and it changes across a single street of the map.

Methodology: these figures come from our analysis of Dallas market data — arms-length home sales, 2021–2025, across the 8 ZIPs shown. They are directional market statistics — aggregate figures, no individual records — and reflect our measurement rather than a peer-reviewed study. The investor and LLC buyer comparison is an aggregate difference between cheaper and affluent ZIPs, not a per-ZIP figure. No individual sale, address, price, or owner is reported here.
