This is the single most common fork in the road for buyers in our market: Arlington Heights or Mount Prospect? They share a border, share School District 214, share the same Metra line — and yet they feel different the moment you drive through. We live and sell in both. Here's the honest breakdown.
Price: the same budget buys more in Mount Prospect
Roughly speaking, Mount Prospect's houses run $280K–$650K with a recent median around $558K, while Arlington Heights runs $350K–$900K+ before you even reach Scarsdale Estates territory north of $1M. The practical version: a budget that gets you a 3-bed near downtown Arlington Heights often gets a 4-bed near downtown Mount Prospect. That premium buys real things — but be sure you're the buyer who values them.
Downtowns: the show vs. the local
Arlington Heights has the bigger stage: streets close all summer for Arlington Alfresco, there's live music at Hey Nonny, sushi at Shakou, and Frontier Days takes over Recreation Park every July. Mount Prospect's downtown is smaller but beloved — Emerson's is everyone's hangout, Canta Napoli makes epic pizza, Trezeros Kitchen + Tap and Le Peep round out the rotation, and Randhurst Village adds big-box convenience nearby. If Friday night walkability is your top criterion, AH wins. If you want a downtown you'll actually use without the crowds, MP holds its own.
Schools: it's a tie at the top, details underneath
Both towns feed Township HSD 214 — and here's the detail most buyers miss: both Prospect High and Hersey draw students from both towns, so the "better schools" argument mostly dissolves at the high-school level. The real difference is K–8: Arlington Heights runs largely on District 25, while Mount Prospect splits between D57, D26 and D59 by neighborhood. All are good; boundaries decide, so verify the address.
Commute: functionally identical
Both sit on the Metra UP-NW line (Arlington Heights has two stations to Mount Prospect's one), both reach O'Hare in about 15–20 minutes, and both use Route 53/I-90 the same way. Nobody should choose between these towns over the commute.
The vibe check
Arlington Heights is the headliner — bigger, glossier, condo towers downtown, the town everyone names first. Mount Prospect is the hometown — a notch quieter, a notch friendlier on price, with neighborhoods like We-Go Park where the whole street seems to be out walking on a nice evening. Neither is wrong. They're different answers to the same question.
Our verdict
Choose Arlington Heights if the downtown scene, the festivals and the prestige addresses are worth the premium to you — start with our ranked AH neighborhoods guide. Choose Mount Prospect if you want the same schools and the same commute with more house for the money — start with our ranked MP neighborhoods guide. And if you're still torn, that's literally our specialty: we grew up here and sell in both towns every year.
