"So we realized something had to be done." That's Harrison Supervisor and Mayor Ron Belmont, talking not about traffic or schools but about who actually covers the town's property tax bill, and how completely that answer had reversed itself by the time he took office.
Most buyers who look at Harrison carry a quiet assumption into the search. PepsiCo has run its world headquarters from a 112-acre Purchase campus since 1970. Mastercard's headquarters sits on Purchase Street. Morgan Stanley's Wealth Management headquarters employs more than a thousand people in town. Surely, the thinking goes, all that corporate real estate means homeowners are riding on someone else's tax bill.
For a stretch of the twentieth century, that was true. It isn't anymore, and understanding why matters more than the median price when you're comparing Harrison to Scarsdale, Rye, or any other Westchester village on your list.
The Ratio That Flipped
At the height of office-park occupancy along what locals call the Platinum Mile, the stretch of Interstate 287 running through Harrison and White Plains, businesses paid roughly 68 percent of Harrison's property taxes while homeowners covered slightly less than a third. That's the kind of commercial cushion buyers picture when they hear "corporate tax base."
By the turn of the century, those numbers had flipped. The reversal wasn't a policy change or a reassessment fight. It was vacancy. Office towers built in the 1970s and 80s for tenants like Texaco and General Foods started emptying out as those companies restructured or left, and by 2010 the vacancy rate along the Platinum Mile hit 30 percent, nearly double the rate for the rest of Westchester County. Empty buildings don't stop needing roads plowed or schools funded. When a commercial parcel's assessed value falls, the tax burden doesn't disappear. It shifts to whoever is still occupying taxable property, which increasingly meant homeowners.
Belmont's quote comes from that moment of recognition, when the town looked at its own numbers and understood the corporate halo effect had quietly stopped working the way everyone assumed it still did.
What Filled the Empty Office Parks
Harrison's response was a 2013 master plan that rezoned sections of the Platinum Mile, sometimes called the "teardrop" area for its shape between I-287, the Hutchinson River Parkway, and I-684, to allow uses beyond single-tenant office space. What moved in over the following decade tells you how far the correction went:
- Life Time Athletic paid $12 million for 22 acres of aging office buildings that Gannett had downsized out of, tearing down the old Journal News building to open a 209,000-square-foot health club.
- Wegmans opened its first Westchester County location on August 5, 2020, a 121,000-square-foot store at 106 Corporate Park Drive, on the site of three more emptied office buildings.
- Toll Brothers, in a joint venture with J.P. Morgan Global Alternatives, converted two vacant 1970s office buildings at 103-105 Corporate Park Drive into Carraway, a 421-unit apartment community that opened in 2021 as the first multifamily housing built in that part of town.
- An office building at 400 Westchester Avenue became Fordham University's Westchester campus, and a former office site became the Hyatt House White Plains.
None of that reads like a corridor still generating a 68 percent commercial tax share. It reads like a town retrofitting a tax base that had already shrunk out from under it, one special-use permit at a time.
Why the Bond Rating Held Anyway
Here's the part that should reassure buyers without changing the underlying math: Harrison carries a AAA bond rating from Moody's, the agency's highest possible grade, reflecting strong reserves and conservative budgeting rather than a booming commercial tax roll. That rating is worth knowing because it tells you the town has managed the shift competently. It does not tell you the shift didn't happen.
| Peak Platinum Mile era | Post-vacancy era | |
|---|---|---|
| Business share of property taxes | ~68% | Minority share |
| Homeowner share of property taxes | Under 33% | Majority share |
| Office vacancy on the corridor | Low | 30% by 2010 |
What This Means for Your Search
If you're comparing Harrison to a neighboring village, the corporate headquarters on your drive through Purchase are real, and they still employ a lot of people who buy homes nearby. What they are not doing, at least not to the degree the town's name recognition implies, is quietly absorbing a large share of your future tax bill. That work now falls more heavily on the residential side than it did in the corridor's 1980s heyday, which is a different comparison than the one most buyers think they're making.
The current market gives some sense of how that plays out in practice. Single-family homes in Harrison had a median sold price of $1,825,000 in February 2026, based on OneKey MLS data, a slight 1.4 percent dip from the same month a year earlier. But months of supply fell nearly 49 percent over that same year, and new listings dropped from 13 to just six. That combination, a soft price signal alongside a sharply tightening supply, is exactly the kind of pattern that looks confusing until you separate the tax-base story from the demand story. Buyers aren't backing away from Harrison. Inventory is just scarce, and pricing on any given month can wobble with a small sample of closings.
None of this means Harrison is a worse buy than a town without a corporate corridor. It means the reason to like Harrison should be Harrison itself, its commute access, its schools, its neighborhoods in Purchase and West Harrison, and not an assumption about corporate neighbors subsidizing your bill. The Platinum Mile's transformation into apartments, a grocery store, a health club, and a university campus is still an asset. It's just a different kind of asset than the one buyers usually picture.
Frequently Asked Questions
Does this mean Harrison's property taxes are higher than comparable Westchester towns? Not necessarily. The point isn't that Harrison's taxes are unusually high, it's that the reason buyers often give for expecting them to be low, a fat corporate tax base offsetting residential bills, doesn't describe the town's current fiscal reality. Comparing actual town and school tax rates side by side with other villages you're considering will tell you more than the presence of a corporate logo on the map.
Is the Platinum Mile redevelopment finished? No. The corridor is still working through the adaptive reuse process the 2013 master plan set in motion, and further conversions of aging office stock are plausible as the town continues to evaluate special-use permits. Anyone weighing a purchase near Corporate Park Drive or the broader teardrop area should expect the immediate surroundings to keep evolving.
