A 1031 exchange is one of the most powerful tools in real estate investing. Sell one property, buy another, and defer paying capital gains tax on the profit, one of several strategies covered in our roundup of real estate tax-saving strategies for investors. It sounds simple, but the mechanics matter, and one misstep can void the entire exchange, leaving you with a full tax bill you were trying to avoid.
Here’s what you actually need to know before you attempt one.
Rule One: Never Touch the Money
The single most important rule of a 1031 exchange is this: you cannot take receipt of the sale proceeds. The moment funds from the sale of your property land in your hands (even briefly!) the exchange is disqualified. The IRS will treat the transaction as a standard sale, and you’ll owe capital gains tax just as if the 1031 exchange never happened.
This isn’t a technicality you can work around with good bookkeeping. It’s a hard line. Which is exactly why the process requires a third party.
Why You Need a Qualified Intermediary
To keep the exchange valid, an independent intermediary steps in to hold the money and manage the transaction on your behalf. Here’s how it works:
- When you sell your property, the intermediary takes possession of the sale proceeds and your rights in that property, holding everything in escrow.
- You then identify and select the replacement property you want to purchase.
- You assign your rights in that new property to the intermediary.
- The intermediary executes the purchase, sending the funds directly to acquire the new property on your behalf.
At no point do the sale proceeds pass through your hands. That’s what keeps the exchange compliant. If you want to dig deeper before diving in, our guide to 12 questions investors need to ask about 1031 exchanges is a good next stop.
One important detail: this intermediary cannot be your title company. It has to be a genuinely independent third party, separate from the entities already involved in closing the deal.

What You’re Still Responsible For
Even though you’re assigning certain rights to the intermediary, you’re not stepping out of the transaction entirely. As the seller, you still sign the deed when the property sells. As the buyer, you still execute the final mortgage documents and other closing paperwork on the property you’re acquiring.
What gets assigned is narrower: just enough control over the contracts so the intermediary can legally manage the funds and complete the exchange without the money ever reverting to you.
Understand the Fee Structure Before You Hire Anyone
Qualified intermediaries charge fees for their services, and the structure is worth understanding upfront. Fees are typically charged per property. That means:
- Buying a single apartment building will likely involve one flat fee.
- Buying a portfolio of ten properties could mean ten separate fees, one for each property in the deal.
This can add up quickly on larger transactions, so it’s worth asking for a full fee breakdown before you commit to working with any intermediary.
How to Find a Legitimate Intermediary
Because the intermediary will be holding your sale proceeds, sometimes a significant sum, legitimacy matters. The best way to find one is through referrals from someone who has actually completed a 1031 exchange before. A personal recommendation gives you a track record to check, rather than trusting a cold search result.
Before you hire anyone, verify that they are a properly established, legitimate company with real experience executing exchanges. The same diligence applies to how you structure the entities that will hold the replacement property, a common source of costly mistakes we cover in our guide to real estate entity structuring. This isn’t a place to cut corners; if the intermediary mishandles the funds or the process, you risk losing both the tax deferral and the money itself.
The Bottom Line
A 1031 exchange can save you a substantial amount in capital gains tax, but it only works if you follow the structure precisely: never touch the sale proceeds, use a qualified and independent intermediary, understand their per-property fee structure, and vet them thoroughly, ideally through a trusted referral, before handing over control of your transaction.
Get those pieces right, and the exchange does exactly what it’s designed to do: let you move your investment forward without the IRS taking a cut along the way.
