Most of the 1031 exchanges I have seen go sideways went sideways in the first thirty days. The seller had one hundred eighty days on the clock to close on a replacement. They had already spent thirty of those days thinking about it. The remaining window converted careful decisions into hurried ones.
The 1031 exchange is the most powerful tax tool in American commercial real estate. It is also the most misused. For an LA multifamily seller sitting on thirty years of Prop 13 basis protection and a building that has appreciated four-fold since acquisition, the 1031 is often the difference between keeping the equity and writing a seven-figure check to the IRS. But the mechanics do not care about your intentions. They care about your calendar.
A 1031 exchange defers federal capital gains tax (and in California, state tax) when you sell one investment property and reinvest the proceeds into another "like-kind" investment property, subject to specific rules and timelines. It is a deferral, not a forgiveness — the tax liability rolls forward into the new property's basis. But the deferral compounds, and many LA owners who have executed multiple 1031s over decades end up with portfolios worth meaningfully more than they would have after paying capital gains tax at each transition.
The rules that matter:
Miss any of these and the exchange collapses into a taxable sale.
Three reasons.
Prop 13 basis preservation. An LA owner who bought a Koreatown building in 1985 for $800,000 has a Prop 13 assessed value that has grown by at most 2% per year since. The market value may be $6 million. A sale at $6 million creates capital gains liability on most of that delta. A 1031 defers it entirely.
High appreciation, wide basis gap. LA multifamily has appreciated more aggressively than most US markets over the last thirty years. The gap between basis and market is wider here, which makes the tax cost of an outright sale larger, which makes the deferral more valuable.
Retirement sequencing. Many LA multifamily owners acquired their buildings in their thirties and forties. They are now in their sixties and seventies and want to step down from active management without liquidating their equity. 1031-into-DST is a legitimate path. 1031-into-net-lease is another. Both preserve the tax position and the cash flow while eliminating the tenant-facing work.
Trap one: identification paralysis. The 45-day clock starts the day escrow closes on your sale. You have 45 days to identify replacement properties in writing. Most sellers have not started looking until day 15. This is the most common failure mode. The fix is to start identifying replacements before you close on the sale. The clock is not your friend.
Trap two: boot. If you trade down — smaller property, less debt, cash out — the difference is taxable. An LA owner selling a $6 million building for a $4 million replacement creates $2 million in boot, taxed at capital gains rates (federal and California) plus depreciation recapture. Boot is the quiet killer of exchanges that looked clean on paper.
Trap three: the wrong DST. Delaware Statutory Trusts are passive fractional ownership vehicles that qualify for 1031 treatment. They are legitimate tools. They are also sometimes sold by people whose incentives are not aligned with yours. A DST with a high sponsor load, low-quality tenant base, or illiquid secondary market can become a multi-decade problem. If you are considering a DST, the sponsor track record and the underlying property quality matter more than the marketing deck.
Trap four: the qualified intermediary who goes out of business. QIs are not federally regulated. Several large ones have gone insolvent over the last two decades, taking exchange funds with them. Use a QI with a strong balance sheet, segregated qualified trust accounts, and insurance. This is not the place to save $500.
LA multifamily 1031 sellers are looking at three buckets of replacement options right now.
Direct replacement in LA. Trading one LA building for another, often smaller, often newer. Works if the exchanger wants to stay in LA and is willing to underwrite to current cap rates. Post-1995 Costa-Hawkins-exempt inventory is the most competitive sub-category.
Out-of-state multifamily. Phoenix, Dallas, Nashville, Austin. Higher cap rates, different regulatory regimes, active operator market. Works if the exchanger has an operator relationship in the new market or hires one. Works less well if the exchanger tries to self-manage from LA.
Passive replacement. DSTs, net-lease single-tenant properties, and structured products. Works if the exchanger's goal is to eliminate active management. The tradeoff is illiquidity and dependence on the sponsor.
A meaningful share of the LA multifamily sellers I work with who do a 1031 end up in passive replacement. Not because it is always the right answer, but because by the time the 45-day clock is running, passive replacement is the one bucket where the transaction can actually close on time.
Before you commit to a 1031, answer these.
One: what is your actual goal — preserve the tax position, step down from management, redeploy capital, or some combination? All are valid. They lead to different replacement strategies.
Two: do you have the discipline to identify replacements in the first 15 days, or are you going to spend 40 of your 45 days deciding? If the latter, pre-identify before you list the relinquished property.
Three: is your QI capitalized and insured? If you cannot verify this in 10 minutes, pick a different QI.
Four: if the exchange fails and becomes a taxable sale, can you absorb the tax liability? Knowing the downside is not the same as accepting it. The answer shapes how much risk you take on the identification side.
Five: what is your estate plan? A 1031 held until death receives a stepped-up basis, which permanently eliminates the deferred tax. For sellers over 65 with heirs, this is often the dominant variable. For sellers with no estate-planning consideration, it is not.
The 1031 is a tool. Like any tool, it is used well by some and badly by others. The sellers who execute clean 1031s are the ones who started planning before they listed the building, chose a QI they vetted, identified replacements early, and understood which part of their goal the exchange was actually serving.
The ones who end up with boot, with a DST they regret, or with a collapsed exchange and a tax bill are almost always the ones who started the process with "my broker told me I should do a 1031."
Your broker should tell you whether a 1031 fits your situation, with specifics. If they cannot, interview a different broker.

What is a 1031 exchange deadline?
Two deadlines. Forty-five days from the close of the relinquished property to identify replacement properties in writing. One hundred eighty days from the same date to close on an identified replacement.
Can I do a 1031 exchange into a DST?
Yes. A Delaware Statutory Trust qualifies as "like-kind" under IRC 1031 when properly structured. DSTs allow passive fractional ownership of institutional-quality real estate, which suits sellers stepping down from active management. Sponsor quality and underlying property matter more than marketing materials.
What happens if my 1031 exchange fails?
If you fail to identify replacements in 45 days or close in 180 days, the exchange collapses and the sale becomes a fully taxable event. The QI typically returns the sale proceeds, and you owe capital gains tax and depreciation recapture on the relinquished property.
How do I avoid boot in a 1031 exchange?
Trade equal or up. The replacement property's total value and debt must equal or exceed the relinquished property's. Any cash received, debt reduction, or value trade-down becomes taxable boot.
Is a 1031 exchange worth it for a small building?
Depends on the gain, not the building size. A seller with a $1 million gain on a $3 million sale avoids significant combined federal and California tax. The overhead of a clean 1031 (QI fees, legal, replacement underwriting) is small relative to the deferral benefit on most gains of meaningful size.
