The 1031 exchange clock is the whole game — and most people start it late

A 1031 exchange lets you defer capital gains tax when you sell an investment property and reinvest the proceeds into another one. That is the part everyone knows. The part that causes deals to fail is the timeline, and the timeline is unforgiving.

Two deadlines run simultaneously from the day your relinquished property closes. You have 45 days to formally identify replacement properties in writing, and 180 days to close on one of them. Those are calendar days, not business days. They do not pause for holidays, for a seller who goes quiet, or for a lender who needs another week. And the 45-day identification window is the one that actually kills exchanges — because most investors start looking for replacement property after their sale closes, which means they have already burned the easiest weeks of the search.

The other mechanical requirement people discover too late: you cannot touch the money. Proceeds have to go to a qualified intermediary before closing on the sale. If the funds hit your account, even briefly, the exchange is generally disqualified. The intermediary needs to be engaged before your sale closes, not after.

Experienced exchangers handle this by lining up replacement candidates before the relinquished property goes under contract. By the time the clock starts, they already know their primary target and their backups. The identification rules give you some flexibility — you can name three properties regardless of value, or more under certain value tests — but that flexibility is only useful if you have candidates worth naming.

The strategic question worth asking before any of this is whether an exchange is actually the right move. Deferral is not the same as forgiveness. The basis carries forward, and you are trading a tax bill today for a constrained search under a hard deadline. Sometimes paying the tax and buying the right asset on your own timeline is the better outcome. That calculation belongs to your CPA, not your broker. Our job is to make sure that when you do decide to exchange, the real estate side is ready before the clock starts.
