How to Defer a Large Capital Gain Through a 1031 Exchange

If you've owned Southern California commercial or industrial property for several years, there's a good chance you're sitting on significant appreciation. Selling that property outright can trigger a large capital gains tax bill — but a 1031 exchange allows you to defer that tax by rolling your proceeds into a new investment property, rather than losing a substantial portion of your equity to the IRS.

What Is a 1031 Exchange?

Named for Section 1031 of the Internal Revenue Code, a 1031 exchange lets an owner sell investment or business-use real property and defer capital gains tax by reinvesting the proceeds into a "like-kind" replacement property. In practice, "like-kind" is interpreted broadly — most real property held for investment or business purposes qualifies, including trading between property types such as industrial, multifamily, retail, or net-leased assets. It does not apply to a primary residence.

One trend we're seeing regionally is investors exchanging out of multifamily and into industrial property, largely due to concerns over rent control and other regulatory pressure on residential assets, combined with the strong long-term fundamentals of Southern California's industrial market.

Key Deadlines You Cannot Miss

The most common structure is a delayed exchange, and it runs on a strict clock:

• 45 days from the close of your sale to formally identify up to three potential replacement properties
• 180 days from the close of your sale to complete the purchase of your replacement property

These deadlines are calendar days, not business days, and they are not extended for weekends or holidays. Missing either one disqualifies the exchange, so timing your sale and lining up replacement candidates in advance is critical.

The Role of a Qualified Intermediary

To properly execute a 1031 exchange, you cannot take possession of the sale proceeds yourself — the funds must be held by a Qualified Intermediary, sometimes called an Accommodator, until they're used to acquire the replacement property. An experienced broker can refer you to a reputable intermediary and help coordinate the identification and purchase process within your deadlines.

Choosing the Right Replacement Property

Not all replacement properties serve the same purpose, and the right fit depends on how involved you want to be:

• Net-leased investments (single-tenant properties leased to a national or regional credit tenant) offer largely passive income with minimal landlord responsibilities.
• Value-add opportunities involve more active management but offer upside potential through lease-up, repositioning, or renovation.
• Stabilized income industrial properties — a category we specialize in — often balance passive cash flow with long-term appreciation potential in supply-constrained SoCal submarkets.

Why Industrial Property Is a Popular 1031 Replacement Right Now

Southern California's industrial market continues to benefit from persistent demand drivers: the Ports of Los Angeles and Long Beach, last-mile e-commerce distribution needs, and severe land constraints that limit new supply. For 1031 exchange buyers, industrial real estate offers a combination of income stability and long-term value that's difficult to find in other asset classes in this market.

Common 1031 Exchange Mistakes to Avoid

• Waiting until after closing to start looking for replacement properties
• Underestimating how competitive well-priced replacement inventory can be within a 45-day window
• Failing to line up a Qualified Intermediary before closing escrow
• Not accounting for how debt and equity must be matched or exceeded on the replacement property to fully defer the gain

Who Should Consider a 1031 Exchange

• Owners selling industrial, multifamily, or other investment property with substantial built-in gain
• Investors looking to reposition capital from management-intensive assets into more passive holdings, or vice versa
• Owners concerned about regulatory pressure on their current asset class (such as rent control on multifamily)
• Anyone selling an appreciated property who wants to preserve equity for reinvestment rather than losing a portion to taxes

Frequently Asked Questions

Do I have to buy a property that's exactly like the one I'm selling?
No. "Like-kind" is broadly defined for real estate — you can exchange between property types, such as multifamily into industrial, as long as both properties are held for investment or business use.

What happens if I miss the 45-day identification deadline?
The exchange is disqualified, and the full transaction is treated as a taxable sale.

Can I use exchange funds for personal use in the meantime?
No. Funds must be held by a Qualified Intermediary and cannot pass through your hands at any point in the process.

Do I need to reinvest 100% of my proceeds to fully defer the gain?
Generally, yes — to defer all capital gains tax, you need to reinvest all net proceeds and acquire a replacement property of equal or greater value, with equal or greater debt (or additional cash to offset any debt reduction).

How early should I start planning a 1031 exchange?
Ideally before you list your property for sale. Identifying your Qualified Intermediary and getting a sense of replacement property options in advance gives you a significant advantage once your 45-day clock starts.
