Lansdowne Is the Sleeper Suburb Philadelphia Investors Keep Overlooking — But Not for Much Longer

Lansdowne Borough's planning commission is preparing to vote on a mixed-use rezoning package that would allow multifamily residential construction along a stretch of Baltimore Avenue currently zoned for single-family use — a shift that local real estate professionals say could push median sale prices past $280,000 for the first time in the borough's recorded sales history. The vote is scheduled for September 2026.

The timing matters because Lansdowne sits at a specific inflection point. SEPTA's Media/Wawa Line stops at Lansdowne station, putting Center City Philadelphia at under 30 minutes by rail. That commute advantage has existed for decades. What has changed is the pressure radiating outward from West Philadelphia, where median rowhouse prices along the Baltimore Avenue corridor between 46th and 58th Streets crossed $375,000 in the second quarter of 2026, pricing out a generation of first-time buyers who are now scanning the Delaware County line for alternatives.

The Rezoning Proposal and What It Actually Allows

The proposed ordinance, circulated by the Lansdowne Planning Commission in May 2026, would reclassify approximately 14 blocks along Baltimore Avenue from R-1 single-family residential to a TC-2 town-center designation. Under TC-2 rules, property owners could build structures up to four stories with ground-floor retail, the kind of density that turns a sleepy commercial strip into something more self-sustaining. The borough's comprehensive plan, last updated in 2019, explicitly identified the Baltimore Avenue corridor as a target for transit-oriented development, so the proposal is not coming from nowhere — it's been telegraphed for years.

Two institutions are paying close attention. The Lansdowne Economic Development Corporation, a nonprofit that administers the borough's business improvement programs, has been briefing commercial landlords on the proposal since spring. Separately, the Delaware County Planning Department offered a formal technical review in June, recommending approval with minor amendments around parking minimums. Neither body has opposition on the record.

Investors who have been tracking comparable corridors in the city point to what happened along Germantown Avenue in Chestnut Hill after Philadelphia's own commercial corridor overlay was expanded in 2021. Assessed values on mixed-use parcels there climbed roughly 18 percent over the following 24 months, according to figures from the Office of Property Assessment. Lansdowne's tax base is smaller and less established, but the directional logic is similar.

The Numbers That Make This a Real Conversation

Right now the arithmetic is unusually accessible. According to Bright MLS data compiled through June 30, 2026, the average days-on-market for single-family homes in Lansdowne sits at 19 days — faster than neighboring Upper Darby Township at 26 days and faster than Drexel Hill at 31 days. Despite that pace, the median sale price remains $241,000, a figure that looks startlingly low against the broader Delaware County median of $318,000. That gap is the opportunity the rezoning could close.

Several parcels along the 100 and 200 blocks of East Baltimore Avenue are currently assessed at between $180,000 and $210,000 for lots that run 25 feet wide and 120 feet deep. Under TC-2 zoning, those same lots could theoretically support a four-unit building with a commercial anchor — a configuration that income investors in South Philadelphia routinely underwrite at valuations north of $600,000.

Fourth of July weekend would normally be prime open-house territory, but the brutal heat gripping the region — enough to cancel outdoor events from Washington to Penn's Landing — has pushed most serious buyers indoors and online, which is where Lansdowne properties are quietly accumulating saved searches and watchlist additions at an unusual rate for a borough of 10,000 residents.

For buyers considering a move before the September vote, the calculus is straightforward: purchase under existing R-1 pricing, absorb minimal holding costs, and potentially benefit from TC-2 uplift without having paid the premium that typically follows a rezoning announcement. That window is narrow. Once the commission votes and the ordinance advances to Lansdowne Borough Council — a process that typically runs 60 to 90 days — asking prices will adjust. They always do.
