Des Moines sits on the Puget Sound waterfront between SeaTac and Federal Way, and its replacement property market is shaped by two very different forces pulling in opposite directions: airport-driven industrial demand inland and marina-district redevelopment on the water. Investors relinquishing a Des Moines asset usually have to choose a lane early, because a Des Moines Creek Business Park flex building and a Marina District multifamily project draw on entirely different tenant pools, financing structures, and management profiles.
Airport-Driven Industrial Along Des Moines Creek
Des Moines Creek Business Park sits within a short truck run of Seattle-Tacoma International Airport, and that proximity has built a steady base of air-cargo-adjacent warehouse, distribution, and flex space along International Boulevard and Pacific Highway South. Tenants here range from freight forwarders to parts suppliers serving airport ground operations, and lease terms tend to track airport-related logistics cycles more closely than the broader King County industrial market. An identification list built around this corridor should note runway proximity, since some parcels carry aviation easements or noise-related use restrictions worth confirming before financing is arranged.
Marina District and Waterfront Multifamily
The Des Moines Marina, one of the larger public marinas on Puget Sound, anchors a waterfront district that has drawn mid-rise multifamily and mixed-use redevelopment along Cliff Avenue and the Redondo waterfront to the south. Replacement candidates here compete more on view corridor and walkability to the marina than on square footage, and older buildings from the marina's original 1970s buildout sit alongside newer construction, so condition and capital-plan history need direct comparison rather than a blanket age assumption.
Pacific Highway South Retail and Lodging
SR-99 through Des Moines carries an older retail and lodging strip built to serve airport travelers, and much of that inventory is smaller freestanding pads rather than anchored centers. Some of this stock has been converted or is under pressure to convert toward multifamily as the city works to redevelop the corridor, which affects how durable a given retail lease is as replacement income. Investors should ask directly about any pending rezone or redevelopment overlay before treating a Pacific Highway pad as a stable long-hold replacement.
Typical Des Moines identification candidates include:
- Airport-adjacent warehouse and distribution buildings
- Flex and light-industrial space in Des Moines Creek Business Park
- Marina District and Redondo waterfront multifamily
- Pacific Highway retail and lodging pads, subject to redevelopment risk
- Small mixed-use buildings near the Marina District core
45-Day Identification and Aviation Easement Review
Because several Des Moines industrial parcels sit inside FAA-related flight path and noise overlay zones tied to Sea-Tac operations, the 45-day identification window should include a pull of any recorded avigation easement alongside the usual title and value review. That detail affects both lender comfort and future exit value, and it is far cheaper to confirm during identification than to discover during the replacement closing. Investors should also flag any Port of Seattle land-use overlay that touches a candidate parcel near the airport boundary.
Qualified Intermediary Coordination Through Closing
A qualified intermediary holds the relinquished-property proceeds from the Des Moines sale and prepares the exchange documentation so the investor never takes actual or constructive receipt of funds between the two closings. Escrow instructions on the replacement purchase, whether it lands in the Marina District or along Des Moines Creek, should route funds directly from the QI, and title work should confirm any shared-access or utility easements common to both the older marina-area buildings and the newer airport-corridor flex product. Investors should confirm the 180-day closing window and specific documentation requirements with their qualified intermediary and tax advisor before finalizing any Des Moines replacement purchase.
Common 1031 Exchange Questions
What kind of replacement property is available in Des Moines?
The market splits between Sea-Tac-adjacent industrial and flex space along Des Moines Creek and Pacific Highway South, and waterfront multifamily or mixed-use in the Marina District. Investors should decide which market they are targeting early, since the two draw different tenants and financing.
Do aviation easements affect industrial property near Sea-Tac in Des Moines?
Some Des Moines Creek Business Park and Pacific Highway parcels carry avigation easements or noise-overlay restrictions tied to Sea-Tac flight paths, which can affect lender terms and future use. That review should happen inside the 45-day identification window.
Is Pacific Highway South retail a stable 1031 replacement in Des Moines?
Some corridor pads face redevelopment pressure toward multifamily as the city works to reshape SR-99, so investors should confirm whether a candidate property carries any pending rezone or redevelopment overlay before relying on it as long-hold income.
Who holds the sale proceeds during a Des Moines exchange?
A qualified intermediary holds the relinquished-property proceeds and prepares the required exchange paperwork so the investor does not take actual or constructive receipt of funds between the Des Moines sale and the replacement purchase.
How much replacement property can a Des Moines investor identify?
Up to three properties of any value under the standard rule, or more properties under the 200% or 95% rules, described specifically enough in a written notice to the qualified intermediary before the 45-day deadline.
