1031 exchange rules, timeline and intermediary

What qualifies, the two deadlines that start at closing and cannot be extended, why the intermediary has to be in place first, and when the whole thing is not worth doing.

What is a 1031 exchange in California?

A 1031 exchange lets an investor selling a San Diego County investment property defer the capital gain by reinvesting the proceeds into other like-kind real property held for investment or business use. Deferral is not forgiveness — the gain carries into the new property's basis and comes due if it is later sold outright.

Like-kind is far broader for real estate than most people expect: a rental house can be exchanged for a commercial building, raw land, or a fractional interest, provided both sides are real property held for investment. What does not qualify is a primary residence, a second home used personally, or property held mainly to flip.

California adds a wrinkle worth knowing if the replacement property is out of state: the state requires continued annual reporting on the deferred gain, and it expects to tax that California-source gain when the chain eventually ends.

What is the 1031 exchange timeline?

The clocks on a San Diego County 1031 exchange both start the day the relinquished property closes: 45 days to formally identify replacement property in writing, and 180 days to complete the purchase. The 180 days runs from the same closing, not from the end of the identification window.

Both are calendar days including weekends and holidays, and neither can be extended for ordinary reasons — not a failed inspection, not a lender delay, not a seller backing out. There is one further trap: the exchange period also ends at the due date of that year's tax return, so a sale late in the year can shorten the 180 days unless the return is extended.

Forty-five days is far shorter than it sounds in a market where finding the right replacement property is the hard part. Serious exchangers start looking before the sale closes rather than after — see the buying timeline for how long the acquisition half realistically takes.

Do I need a qualified intermediary for a 1031 exchange?

A qualified intermediary is required for essentially every San Diego County 1031 exchange, and must be engaged before the sale closes. An investor who takes receipt of the sale proceeds — even briefly, even into their own escrow account — has ended the exchange and triggered the tax.

Constructive receipt is the single most common way these fail, and it is unfixable after the fact. The proceeds have to move from the buyer to the intermediary and from the intermediary to the replacement purchase, without passing through the investor's hands at any point.

Choose the intermediary carefully, because the role is loosely regulated and the intermediary is holding all of the money. Ask about bonding, insurance and how funds are segregated. Your own agent, attorney or accountant is generally disqualified from acting in the role.

Is a 1031 exchange worth doing?

A 1031 exchange is worth it for a San Diego County investor with a substantial deferred gain who genuinely intends to stay invested in real property. It is a poor fit for someone who wants out of property altogether, or whose gain is small enough that the costs and the compressed timetable outweigh the deferral.

The pressure the deadlines create is a real cost and it is routinely underestimated. Buying a mediocre replacement property on day 44 to preserve a deferral is a common and expensive mistake — the tax saved can be smaller than the price of the compromise.

A note on what this is

The above describes how the mechanism works. It is not tax advice, and no page can be — the treatment of any actual exchange depends on facts this one does not know. Engage a qualified intermediary and a CPA before the relinquished property goes into escrow, because most of what can go wrong here cannot be corrected afterwards.
