Walk a few blocks off Glen Street and you'll notice it before you notice much else: the two-family houses. Wide front porches split into two doorbells. A driveway shared by two mailboxes. A "For Sale" sign that mentions, almost in passing, that the second floor comes with a tenant already in place.
If you've been comparing homes in Glens Falls against other spots in the Adirondack corridor, you've probably run into the pitch. Buy a legal two-family near downtown, live in one unit, rent the other, and let a tenant cover a meaningful chunk of your mortgage. On paper, in a market where a lot of these properties still list in the high $100,000s to low $300,000s, it looks like one of the better affordability plays in the region.
The math isn't wrong. It's just about to get more complicated, because the rent half of that equation is walking into a wave of new competition that most listing descriptions never mention.
The Pitch You Keep Seeing
The listings tend to read the same way. A duplex near downtown, one unit occupied, one vacant or rented below market, and a note that the property "may be possible" to purchase as an FHA owner-occupied buy. That phrase is doing a lot of work. FHA financing lets an owner-occupant buy a property with up to four units and put down as little as 3.5 percent, far less than the 20 percent typically expected on an investment property. Because you're planning to live in one unit, the lender treats it as owner-occupied housing rather than a straight rental purchase, and the rent from the other unit or units can help you qualify for the loan and offset the payment once you own it.
That's the appeal in a sentence: less cash out of pocket, a tenant helping with the note. It's a real strategy, and it's one reason Glens Falls attracts first-time buyers who'd otherwise be priced into a smaller single-family home in Queensbury or Saratoga Springs at a comparable payment.
What Buyers Are Actually Comparing
Here's where it gets specific. As of March 2026, multi-family listings in Glens Falls carried a median price of $259,900 and an average sale price of $276,191, with those properties spending a median of just 12 days on the market before going under contract. That's a fast-moving segment, and it's being driven by exactly the buyer described above: someone doing the FHA math on a duplex or triplex rather than shopping a plain single-family home.
Current listings give a sense of what sellers assume they can charge for that second unit. One active two-family listing in the city advertises $1,400 a month per unit as the going rent. That number isn't a citywide average, it's one seller's asking figure, but it's a fair proxy for what an owner-occupant buyer is being told to expect from an older upstairs or downstairs apartment near downtown.
The assumption baked into every one of these listings is that $1,400 a month, or something close to it, holds steady. That assumption is the part worth testing before you write an offer.
The Supply Wave That Isn't in Any Listing Description
While individual sellers are quoting per-unit rents on 80- and 100-year-old duplexes, the city is in the middle of adding a meaningful amount of brand-new rental housing to the same downtown-adjacent footprint.
Bonacio Development broke ground in October 2025 on South Street Apartments, a $27 million, 70-unit development built with support from New York State Homes and Community Renewal, with space on the first floor leased to SUNY Adirondack. A few blocks over, Green Springs Capital Group is converting a vacant three-story building at 178-180 Maple Street into 19 apartment units, a $4.5 million project the developer said in February 2026 he expected to complete by mid-2026, with an average target rent of roughly $1,275 a month. And at 10 Broad Street, Patten Property Management is finishing The Point, a downtown building marketed with keypad entry, elevator access, and on-site security cameras, with completion anticipated in fall 2026.
Add those up and you get well over 100 new units landing in the same rental pool that older duplex owners have relied on for decades, arriving within roughly a year of each other. The Maple Street number is the one that should catch a buyer's attention. A brand-new one-bedroom with modern finishes, targeted at around $1,275 a month, is priced at or below what an existing MLS listing is quoting for an older duplex unit right now. New construction isn't just adding competition on amenities. In at least one case, it's underpricing the existing stock.
Here's how that comparison looks side by side:
| Typical existing unit in an older duplex | New construction unit (2026 pipeline) | |
|---|---|---|
| Example asking rent | Around $1,400/month (per current listing) | Around $1,275/month target (Maple Street project) |
| Parking | Often a shared driveway or street parking only | Dedicated on-site parking in several new projects |
| Building systems | Character, hardwood floors, sometimes separately metered utilities | New mechanicals, keypad entry, on-site management |
| Availability | Available now | Delivering summer through fall 2026 |
A tenant weighing those two options isn't automatically choosing the older unit just because it's cheaper, because in this case it might not be. That's the friction a buyer underwriting a Glens Falls two-family needs to price in now, not after closing.
Parking Is Doing More Work Than People Think
There's a second piece to this that rarely comes up in a listing sheet. Older duplexes near downtown were mostly built before anyone planned for two cars per household, which means off-street parking is often limited to a narrow shared driveway or whatever's available on the street.
Glens Falls Mayor Diana Palmer addressed this directly in a May 2026 speech outlining her first 100 days in office. She pointed to a new planning and zoning department created to streamline development review, and to a change extending the two-hour downtown parking limit to three hours, moves she connected in part to the volume of new apartment and condo units opening downtown. If parking is already a strained resource for existing tenants, a newer building with a dedicated lot has an edge that an older duplex with a shared driveway can't easily match.
The One Advantage Older Duplexes Still Have
It isn't all headwind. Glens Falls has two historic districts listed on the National and New York State Registers of Historic Places, the Three Squares Historic District covering most of the central business district and the Fredella Avenue Historic District. Unlike Saratoga Springs, where a local Design Review Board has real authority over exterior changes to historic properties, Glens Falls has no local preservation law protecting these districts from alteration or demolition.
That's not a reason to skip due diligence on an older home, but it does mean an owner of a duplex in one of these areas generally has more room to renovate, add parking, or update finishes without clearing a design review process first. If new supply is going to compete on modern mechanicals and dedicated parking, that flexibility is exactly the lever an owner of an older two-family has to close the gap.
What to Actually Underwrite Before You Write an Offer
If you're seriously comparing a Glens Falls two-family against a single-family home elsewhere in the corridor, a few things are worth confirming before the rent number on the listing sheet becomes the rent number in your mortgage math.
- Confirm the certificate of occupancy shows the property as a legal two-, three-, or four-family, not a single-family home with an informal second unit. Lenders and inspectors will catch this, but it's worth knowing before you're three weeks into a contract.
- Ask for actual leases and payment history on any occupied unit, not just the seller's stated asking rent.
- Talk to a local property manager about achievable rent for a comparable unit given what's opening downtown in the next 12 to 18 months, rather than what a similar unit rented for two years ago.
- Check what parking is actually available on-site, and whether the property has room to add a spot or two if that becomes a selling point later.
- Build your mortgage math around rent holding flat, or even softening slightly while new supply leases up, rather than assuming steady increases.
A Few Questions Worth Asking
Does buying a two-family in Glens Falls still make sense with all this new supply coming online? For many buyers, yes. The FHA financing advantage and lower entry price haven't gone anywhere. The change is in how conservatively you should model the rental income, not whether the strategy works at all.
Will new downtown apartments push rents down everywhere in the city? Not necessarily everywhere, but they're most likely to affect similar unit types close to downtown, which is exactly where most of the older two- and three-family stock sits.
How do I know if a property I'm considering is a legal multi-family? Ask for the certificate of occupancy and confirm it matches the number of units being marketed. This is a standard part of due diligence during a purchase, and it protects you from inheriting a nonconforming use.
