Downers Grove
Downers Grove is a corporate-corridor suburb, and the I-88 East-West Tollway is the spine that explains most of its commercial real estate. I've worked exchanges here for owners of office buildings that lease to companies doing business up and down that corridor, and the pattern is consistent: I-88 office demand rises and falls with corporate real estate decisions made well outside Downers Grove itself.
Three Distinct Pieces of One Suburb
The downtown core, walkable, centered on the Metra BNSF Line stop, has held up better than a lot of suburban downtowns because it never over-built retail and kept a genuine local restaurant and service base. That's a different animal from the I-88 corporate corridor, where office towers built for single large tenants have had to adjust to a post-pandemic leasing environment that favors smaller footprints and shorter terms.
Then there's the medical corridor around Advocate Good Samaritan Hospital, which has proven to be the most resilient of the three. Medical office tied to the hospital's referral network doesn't move with corporate leasing cycles the way I-88 towers do, and that stability shows up in how these buildings trade.
Belmont Underpass and the Village's Own Priorities
Downers Grove has spent real money and real political capital on projects like the Belmont Road underpass, aimed at untangling downtown traffic from the BNSF tracks, and that kind of infrastructure investment tends to support the downtown core's value over time even when broader office trends are working against the I-88 corridor. It's a useful signal for how the village prioritizes its own tax base, and it's part of why I steer sellers toward downtown mixed-use when they're undecided between that and an aging I-88 office building.
Downers Grove North and South high schools also anchor two distinct halves of the community with their own retail and service patterns, worth knowing if you're comparing neighborhood retail on opposite sides of town rather than assuming the village is one uniform market.
What Sellers Replace Into
Downers Grove exchange proceeds tend to flow toward a handful of categories that reflect this three-part market structure.
- Medical office near Good Samaritan Hospital, prized for its referral-driven tenant stability
- Downtown mixed-use and retail near the Metra stop, benefiting from consistent commuter foot traffic
- Smaller-footprint professional office along I-88, restructured for the post-pandemic leasing environment
- Multifamily in the walkable core, generally in strong demand given the Metra access
- DST allocations for sellers exiting older I-88 office assets that require significant repositioning capital
I-88 office is the category that requires the most caution right now. A building's value depends heavily on whether ownership is willing and able to fund the tenant improvements needed to compete for smaller, shorter-term leases, and that's a very different underwriting exercise than it was a decade ago.
Underwriting Against a Changing Office Market
If your relinquished property is I-88 corporate office, don't assume the replacement search will be quick. Buyer pools for that specific asset type have narrowed as more investors favor medical office or multifamily instead. I generally recommend Downers Grove sellers in this position start identifying backup categories, medical office or downtown retail, well before the 45-day window closes, rather than waiting to see if a comparable office deal materializes.
DuPage County Closing Practices
DuPage County title and recording practices are generally efficient compared to Cook County, but tax reassessment cycles here can still shift the income picture on both sides of an exchange. Loop your CPA in on current assessed values before finalizing a replacement property, particularly for office assets where reassessment risk is more pronounced right now. That extra review is a small cost compared to discovering a surprise tax bill after the exchange has already closed, and it's a conversation worth having before an offer goes in rather than after. Downers Grove sellers moving between asset classes, say, out of I-88 office and into medical office or downtown retail, benefit the most from this kind of early tax review, since the two categories can carry meaningfully different assessed-value trajectories.
Common 1031 Exchange Questions
Is I-88 corporate office still a good replacement category in Downers Grove?
It depends heavily on the building's ability to compete for smaller, shorter-term leases, which is the direction the post-pandemic office market has moved. Buildings requiring significant tenant improvement capital should be underwritten more conservatively than they might have been a decade ago.
Why is medical office near Good Samaritan Hospital considered more stable?
Tenant demand there is tied to the hospital's referral network rather than broader corporate leasing cycles, which has made it more resilient through recent office market softness. It's a common replacement choice for sellers exiting harder-hit I-88 office assets.
Can I exchange Downers Grove office for downtown retail instead?
Yes. Both qualify as real property held for investment or business use, so the asset class can change as part of the exchange. Many sellers make exactly this move given how differently these submarkets have performed recently.
How does DuPage County tax reassessment affect my exchange planning?
It doesn't change the federal 45-day or 180-day deadlines, but it can affect the income underwriting on both the relinquished and replacement property, which is worth reviewing with your CPA before finalizing your identification list.
Do you provide legal or tax advice?
No. This page describes how exchanges are typically coordinated for Downers Grove property and is not a substitute for advice from your attorney, CPA, or qualified intermediary based on your actual transaction.
