That Plymouth Meeting DoubleTree Isn't Coming Back. And Your Aging Hotel Might Be Next.
A hospitality REIT bought a suburban Philadelphia DoubleTree for $22.3 million in 2022, closed it last November, and just won zoning approval to convert all 253 rooms into 213 apartments. The math that killed this hotel is the same math staring at half the aging select-service properties in suburban America right now.
Let me tell you what $88,000 per key looks like when nobody wants to be a hotel anymore. It looks like a six-story building off the Pennsylvania Turnpike that spent 38 years as a DoubleTree, got bought by a hospitality REIT for $22.3 million during the post-pandemic fire sale, operated for roughly three years, and then... closed. Lights off. Doors locked. The owner looked at the numbers, looked at the PIP that was almost certainly coming, looked at the residential rental market in Montgomery County, and made a decision that should keep every owner of a 1980s-vintage suburban full-service property up tonight.
Here's what the conversion math looks like, and it's almost elegant in its brutality. Take 253 hotel rooms. Reconfigure them into 173 one-bedrooms at $1,585 a month and 40 two-bedrooms at $2,325. That's roughly $367,105 in gross monthly residential revenue at full occupancy... call it $4.41 million annually. Now compare that to what a 253-key suburban DoubleTree was generating in a market where business transient never fully recovered, where the PIP conversation with the brand was going to start with a number north of $5 million, and where you're staffing housekeeping, front desk, F&B, and engineering 24/7 for an asset that was built when Reagan was in his first term. The apartments don't need a night auditor. They don't need a breakfast buffet. They don't need 154 gallons of water per occupied room per day (the apartments will use roughly 109, which means even the utility bill gets lighter). The conversion isn't just financially rational. It's almost obvious.
And that "almost obvious" is the part that should scare you if you're an owner sitting on a similar asset. Because this isn't a one-off. Over 9,100 apartments were created from hotel conversions nationally in 2024 alone... a 46% jump from the year before, representing more than a third of all adaptive reuse projects in the country. This is a trend with momentum, and it's feeding on exactly the type of property that's hardest to defend: Class B and C hotels in suburban markets with aging physical plants, thinning margins, and brand requirements that assume a level of investment the operating income can't support. The Plymouth Meeting mall across the street? Also being redeveloped into mixed-use residential. A nearby office building? Converting to 149 apartments. The entire commercial real estate ecosystem around this former DoubleTree is pivoting to residential. The hotel was the last domino.
What fascinates me (and what the press coverage completely misses) is the zoning argument. The developer told the board that apartments are of "the same general character" as an extended-stay hotel. The planning commission didn't buy it... voted 4-3 against. But the zoning board did, 3-1. That argument is going to get replicated in every suburban municipality in America where an owner wants to convert an aging hotel, and the precedent matters enormously. Because the moment a jurisdiction accepts that residential use is functionally equivalent to hospitality use for zoning purposes, the conversion pipeline opens wide. If you're an owner evaluating whether to sink PIP capital into a 30-plus-year-old suburban property, you need to understand that your exit strategy just got a new option... and your competitor across the highway might already be exploring it.
The developer is promising tenants by summer 2026, which is ambitious given the hotel just closed in November (I've watched enough conversions to know that "summer" usually means "late fall if we're lucky"). But the positioning is smart... pricing below the local average by undercutting comparable one-bedrooms by roughly $60 and two-bedrooms by nearly $400. They can do that because they bought a distressed hospitality asset in 2022 at a basis that residential developers building from scratch can't touch. That's the real story here. The pandemic didn't just hurt hotels temporarily. It created an acquisition window that made hotel-to-residential conversions pencil at price points that undercut new construction. And for the families and operators still running the hotels that DIDN'T get converted? You're now competing for market relevance in a submarket that's literally being rezoned out from under you.
If you own or manage a suburban full-service or extended-stay property built before 1995, you need to run the conversion math this week. Not because you're necessarily going to convert... but because someone in your comp set might, and when they pull 253 rooms out of your market's supply, your RevPAR picture changes overnight. Call your broker. Ask what your building is worth as a residential play versus a hotel. If the residential number is higher (and for a lot of you, it will be), that's either your exit strategy or your competitor's. Either way, you need to know the number before someone else figures it out first.
