An investor scanning Biddeford listings this summer will likely stumble across the same piece of news twice: in June 2025, the University of New England moved its College of Osteopathic Medicine out of Biddeford and into a new health sciences building on its Portland campus. For anyone underwriting a 2-4 unit deal near the Pepperell Mill or Main Street, that fact reads like a warning. Medical students are graduate tenants with steady stipends and multi-year leases, exactly the kind of renter a small landlord builds a pro forma around. Lose them, the logic goes, and you lose your cushion.
The closed-sale numbers from the first half of 2026 tell a different story. Biddeford didn't cool. It led every town in Southern Maine in multi-family transaction volume, and it did so at a price well below its neighbor to the north. The story an investor assumes they're walking into isn't the one the market is actually running.
What Actually Left, and What Didn't
The medical school relocation is real. UNE's College of Osteopathic Medicine, the only osteopathic program in New England, now operates out of the Harold and Bibby Alfond Center for Health Sciences on the Portland campus, which opened in 2025 alongside a new institute for interprofessional education. That's a genuine shift in where graduate health science students live, study, and rent.
But the Biddeford campus didn't empty out behind it. UNE enrolled 3,884 undergraduates as of fall 2024, the bulk of them in the College of Arts and Sciences programs based on the Biddeford campus, and university housing policy only guarantees dorm space to first-years, who fill five reserved halls. Upperclassmen live in suite arrangements on campus, but plenty look off campus once they clear their first year or age out of the housing requirement, and off-campus rental listings built specifically around the Biddeford campus are still active today. The medical students who left were a slice of the rental pool, not the foundation of it. The foundation was always the undergraduates, and they're still there.
The Numbers That Don't Match the Warning
Here's where the pro forma gets interesting. Closed 2-4 unit multi-family sales tracked through Maine's regional MLS from January through late June 2026 show Biddeford recording the highest transaction volume of any Southern Maine town in that stretch, with more than half of those properties selling within 30 days. Saco, its neighbor immediately to the north and long considered the more established rental corridor, closed fewer multi-family sales over the same window, but at a noticeably higher price and a much faster clip.
| Biddeford | Saco | |
|---|---|---|
| Closings (Jan-Jun 2026) | 17 | 13 |
| Median sale price | $520,000 | $606,000 |
| Typical pace | Over half sold within 30 days | Median 7 days on market |
Read those two rows side by side and a pattern emerges. Saco is tighter and pricier, the kind of market where a well-priced triplex gets bid up in a week. Biddeford has more volume moving at a gentler pace, at an entry price nearly $90,000 lower. That's not the signature of a market losing its tenant base. It's the signature of a market still absorbing a wave of new supply and turnover, one that hasn't caught up to Saco's pricing yet even as more deals close.
If the medical school departure were actually thinning demand, you'd expect Biddeford's volume to fall behind Saco's, not outpace it. Instead the opposite happened, which means something else is doing the work.
What's Actually Filling the Gap
Two things are happening in Biddeford at once, and neither has anything to do with UNE's medical program.
The first is the second wave of mill conversions. The Lincoln Mill redevelopment, a 240,000-square-foot former textile mill just off Main Street, was slated to add roughly 147 apartments along with a hotel, restaurant, and fitness facility when Governor Janet Mills toured the project in 2021, and it has since become one of the anchors of the district's residential base. Further down Pearl Street, the Riverdam Mill redevelopment is planned to add 71 apartment units, including 7 set aside at workforce housing rates, alongside retail tenants like Blaze Brewery & Restaurant. The city's Pearl Street reconstruction, backed by a federal Economic Development Administration grant, was designed specifically to support that corridor's parking garage and surrounding development, which city officials have projected could add as many as 645 jobs and catalyze $170 million in private investment across the district over time. That's a lot of new renters and new employees landing in downtown Biddeford with no connection to the medical school at all.
The second is quieter but just as important: a generation of landlords who bought Biddeford triple-deckers decades ago is retiring. Listings across the city describe multi-unit buildings with long-tenured tenants at will and rents that have stayed flat for years because the owner never needed to push them. That's inventory finally reaching the market, and it's a different kind of opportunity than a hot Saco duplex that sells above asking in a week. A Biddeford building with below-market rents and a retiring seller is a value-add play: the price reflects today's income, not tomorrow's, and the upside belongs to whoever buys it with a plan to reposition it.
What This Means If You're Comparing the Two Towns
An investor weighing Biddeford against Saco on price alone is comparing two different kinds of deals. Saco's faster pace and higher median reflect a market where the upside is already priced in. You're paying for stability and rents that likely already sit close to market. Biddeford's lower median and slower absorption reflect a market where some of that upside hasn't been captured yet, whether because a building's rents are below market, or because the mill district's newest residential inventory is still leasing up and finding its rent ceiling.
Neither is automatically the better deal. A buyer who wants a turnkey property with predictable cash flow from day one has good reason to lean toward Saco's tighter, faster corridor. A buyer comfortable underwriting a renovation and a rent repositioning, particularly in a triple-decker with tenants at will, has more room to work with in Biddeford, and a lower basis to work from. That kind of value-add math is exactly where having construction expertise in your corner matters. Knowing what a below-market unit actually needs to reach market rent, and what that renovation costs before you close, is the difference between a spreadsheet projection and a plan you can execute.
A Few Questions Worth Asking Before You Offer
Does UNE's medical school move actually reduce rental demand in Biddeford? Not by the numbers so far. The medical program was a graduate-tenant segment, but the undergraduate population that anchors much of the campus-adjacent rental market has stayed roughly the same size, and mill district growth has added renters and jobs downtown independent of the university.
Why is Biddeford's median multi-family price still lower than Saco's if demand is this strong? Because Saco's rental corridor is more established and already priced near the top of what current rents support, while Biddeford is still working through legacy below-market leases and newly delivered mill district units that haven't fully found their ceiling. Price tends to catch up to volume with a lag.
Is the mill district's growth finished, or still underway? Still underway. Riverdam Mill's units and the surrounding Pearl Street corridor represent an ongoing build-out, not a completed chapter, which means the renter base downtown is likely to keep growing for a while yet.
The version of Biddeford worth underwriting in 2026 isn't the one built around a university department that already left. It's the one built around undergraduates who are still there, a mill district still adding units and jobs, and a supply of long-held buildings finally coming to market as their owners retire. That's a more interesting story than the one everyone tells, and it's the one the closed sales actually support.
