Section 1031 does not require an exchanger to reinvest proceeds from one relinquished property into a single replacement property; proceeds can be split across two, three, or more replacement properties, closed on different dates, as long as all of them are identified within the same 45-day window and all closings complete within the same 180-day period measured from the original relinquished property's sale. The exchange is evaluated as a whole: total replacement value and total debt replacement across every acquired property, compared against the relinquished property's sale price and existing debt.
This flexibility is what makes DST allocations practical as a partial-reinvestment tool: an exchanger can buy one direct property with most of the proceeds and place the remainder into a DST interest sized to whatever is left, rather than forcing every dollar into a single asset that may not exist at exactly the right price.
The three-property rule allows identifying up to three properties of any value; the two-hundred-percent rule allows identifying more than three as long as their combined fair market value does not exceed two hundred percent of the relinquished property's sale price; the ninety-five-percent rule allows identifying any number of properties regardless of combined value, but only if at least ninety-five percent of the total identified value is actually acquired. An exchanger targeting several replacement properties needs to choose which rule governs the identification before the 45-day window closes, since exceeding the limits under one rule without qualifying for another can invalidate the entire identification.
A common structuring choice is to identify two or three direct properties plus a DST interest under the three-property rule, giving the exchanger flexibility to close on whichever combination actually works out.
Each replacement property in a multi-property exchange can close on its own schedule inside the 180-day window; they do not need to close simultaneously. This is useful when one property is ready to close quickly and another requires longer due diligence or financing, but it also means the exchanger needs to track separate closing timelines against a single shared deadline, since a delay on one property does not extend the deadline for the others.
The qualified intermediary allocates proceeds to each closing as it occurs, and any proceeds left unallocated once the 180-day window passes become taxable boot regardless of how many properties were successfully acquired before the deadline.
A frequent multi-property structure pairs one directly owned property, often chosen for a specific tenant, location, or management preference, with a DST interest that absorbs the remaining proceeds precisely. This avoids the common problem of a direct property's purchase price falling short of the total required reinvestment by an amount too small to justify searching for a second direct property, since a DST allocation can be sized to close that specific gap.
Debt replacement across multiple properties is calculated in aggregate: if the relinquished property carried debt that has been paid off, the combined new debt across all replacement properties, direct and DST, needs to at least match it, or the exchanger needs to contribute additional equity to cover the difference.
The reverse situation, selling several relinquished properties as part of one combined exchange, is also permitted, and is common for owners consolidating a portfolio of smaller properties into fewer, larger replacement assets or into DST interests. Each relinquished property's sale can close on its own date, but the 45-day and 180-day windows are generally measured from the earliest relinquished property closing in the exchange, which compresses the available time for later-closing relinquished properties compared to a single-property exchange.
Exchangers consolidating several sales into one exchange should sequence the relinquished closings with the shortest, not the longest, available identification window in mind.
Splitting proceeds across multiple properties adds coordination complexity without adding time; the 45-day and 180-day windows apply to the exchange as a whole, not separately to each replacement property. An exchanger pursuing multiple replacement properties should have every acquisition, direct and DST alike, underwritten and ready to move before the identification deadline, rather than treating the multi-property structure as a way to buy more time to search.
