I've closed over $488 million in apartment deals across Los Angeles. And I can tell you with absolute certainty: a 1031 exchange is one of the most powerful tax tools available to multifamily investors. But it's also one of the easiest to screw up.
Most brokers don't understand the mechanics well enough to explain them clearly. Most owners don't ask enough questions. And most mistakes happen because someone thought they had more time than they actually do. This guide is built on real deals, real timelines, and real consequences I've watched unfold.
Here's the plain English version: You sell an investment property. Instead of paying capital gains tax on the profit, you take those proceeds and buy another investment property of equal or greater value. If you do this correctly, you defer the entire tax bill to some future date—possibly indefinitely.
The IRS allows this under Section 1031 of the tax code. The catch? There are strict timelines. Miss them by one day and you lose the entire benefit. I've seen it happen. It's brutal.
Like-kind property means investment real estate can be exchanged for other investment real estate. An apartment building can be exchanged for an office building. A duplex can be exchanged for a strip mall. It doesn't have to be the same type of property—just the same investment category.
You have 45 calendar days from closing on the sale of your property to identify replacement properties in writing. Not business days. Calendar days. Weekends count. Holidays count.
You then have 180 calendar days total from the sale closing to actually close on your replacement property. Let me repeat: total. Not 180 days after you identify. 180 days from your original sale close.
I watched a client miss the 180-day window by three days on a large exchange. The financing closed on day 177. The title transfer paperwork sat on someone's desk over the weekend. The escrow closed on day 182. The entire tax deferral was voided. That's a seven-figure tax bill that could have been avoided.
These timelines are absolute. There are no extensions. There are no exceptions. Your accountant can't call the IRS and ask for five more days. Mark both dates on your calendar before you list the property for sale.
Within that 45-day window, you need to formally identify which properties you're going to buy. The IRS gives you three different options:
Rule 1: The Three Property Rule. You can identify up to three properties, no matter their value. Three is the limit. This is what most people use.
Rule 2: The 200% Rule. You can identify more than three properties, but their combined value cannot exceed 200% of the value of the property you sold.
Rule 3: The 95% Rule. You can identify unlimited properties as long as you purchase 95% of the total value of all identified properties within the 180 days.
Most investors use Rule 1. It's simple. Pick three properties you actually want to buy and move forward.
If you're selling a property in Los Angeles worth $5 million or more, you're paying the Measure ULA transfer tax. It's a 4% tax on sales over that threshold. Measure ULA applies to the sale itself—not to the exchange process—but it affects your 1031 calculation.
Here's why: When you calculate the value of replacement property you need to acquire, you need to use the net proceeds from your sale after the Measure ULA tax has been paid. If you sell a $10 million apartment building, Measure ULA is roughly $200,000. Your net proceeds to reinvest drop accordingly.
Don't underestimate this. I've seen owners think they could reinvest the same gross sale price. That's not how it works.
If you own an RSO rent-controlled building and you're exchanging into another property, understand that rent control restrictions transfer with the property. You can't escape rent control by doing an exchange.
If you're trying to exit rent-controlled exposure, plan for that explicitly. Buy properties in jurisdictions without rent control or buy properties with units outside the RSO scope.
After hundreds of closed transactions, I've seen the mistakes that kill deals:
Mistake 1: Miscounting the days. Owners start counting from "after closing" instead of from the closing date itself. The 45 days starts on day one of closing, not day two.
Mistake 2: Not using a qualified intermediary. You cannot hold the proceeds from your sale yourself, even for one day. The money must go to a qualified intermediary immediately. If you touch the cash, the exchange fails.
Mistake 3: Identifying properties you can't actually buy. If financing falls through on all three identified properties, you still have only 180 days to close on a replacement. Have backup options ready.
Mistake 4: Not coordinating with your accountant early. Your CPA needs to know you're doing a 1031 from day one of the sale. Too many owners keep their accountant out of the loop until close and then discover their replacement property doesn't qualify.
A delayed exchange is the standard structure: sell first, then buy within the 45/180-day window. This is what most people do.
A reverse exchange flips it: buy the replacement property first, then sell your original property within 180 days. This is more complex, more expensive, and requires a specialized intermediary. Most won't touch reverse exchanges.
For most LA apartment owners, stick with delayed exchanges. They're simpler, cheaper, and don't create unnecessary risk.
A 1031 makes sense when you want to upgrade properties, exit a lower-appreciation area, consolidate multiple smaller buildings into one larger property, or defer a significant tax bill while repositioning your portfolio.
A 1031 doesn't make sense when you want to cash out entirely, need liquidity for personal reasons, or are trying to downsize—a 1031 requires equal or greater value, so you can't reduce your portfolio without triggering capital gains.
A Delaware Statutory Trust (DST) is a fractional ownership structure in real estate. You can use a DST as your replacement property in a 1031 exchange if you can't find a full property you want to own outright. This is a backup option, not a first choice—DST fees are higher and you have no control over property management. But if you're running out of time, a DST lets you complete the exchange and defer your taxes.
Your qualified intermediary holds the sale proceeds and coordinates the purchase. Look for specific experience with apartment building exchanges in California, established relationships with title companies, clear fee structure ($1,500 to $3,500 is typical), and references from other multifamily investors in LA.
Don't go cheap on intermediary selection. An intermediary who misses a deadline costs you millions in lost tax deferral.
If you're navigating a 1031 exchange on an LA apartment building, the timeline pressure is real and the stakes are high. I'm happy to walk through the specifics of your situation—the timelines, the property identification, the Measure ULA impact. Give me a call at (916) 996-4421 or shoot me an email at taylor@thegroupcre.com.
Your entire 1031 exchange fails and you owe capital gains taxes on the full gain from your original sale. There are no extensions, no exceptions, and no way to fix it after the fact. The IRS treats these deadlines as absolute.
Measure ULA is a 4% transfer tax on LA property sales over $5 million. It reduces your net sale proceeds flowing to the qualified intermediary, meaning you have less capital to reinvest in your replacement property.
