A standard forward 1031 exchange costs roughly $3,000 to $6,000 in exchange-specific fees — the qualified intermediary, tax advisory work, and Form 8824 preparation — on top of the ordinary closing costs you’d pay on any two real estate transactions. That’s the checkbook answer for most deals. The harder part of the 1031 exchange cost question is which of those expenses you can pay out of the sale proceeds and which you have to cover with separate funds, because using exchange money for the wrong item creates taxable “boot” and quietly undoes the deferral you paid all those fees to get.
Qualified Intermediary Fees
A deferred exchange requires that you never take possession of the sale proceeds. The Treasury regulations lay out four safe harbors that prevent constructive receipt, and in practice almost every exchange uses a Qualified Intermediary (QI) — the third party that holds the funds, prepares the documents, and disburses money to close the replacement property.1eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges
Most QIs charge a flat fee for a straightforward forward exchange with one relinquished property and one replacement property. Expect $750 to $1,500. Extra properties, expedited documents, or complex identification strategies raise the fee. Wire transfer charges run $30 to $50 apiece and add up on multi-property deals, and some firms tack on small administrative fees for holding funds.
If the deal collapses before the QI receives any money, there’s usually a cancellation fee. One national firm publishes $500 for a cancelled forward exchange and $750 for a cancelled reverse exchange. Read the engagement agreement before you sign.
QI fees are treated as valid exchange expenses, which means they can be paid straight from the sale proceeds without creating boot. That treatment doesn’t extend to every cost in the deal, and the difference drives most of the planning that follows.
Why Boot Determines How You Pay Each Cost
Boot is any value you receive in an exchange that isn’t like-kind real property, and it comes in two forms. Cash boot is money you actually pocket: sell for $500,000, buy for $400,000, and the $100,000 left over is taxable. Mortgage boot works the same way with debt — if the mortgage on the replacement is smaller than the mortgage on the property you sold, the debt relief is boot unless you plug the gap with extra cash.2Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment
Here’s why that matters for costs. The IRS lets you pay certain transaction expenses out of exchange proceeds without treating those payments as boot. Pay a non-qualifying expense from those same funds, though, and the IRS treats the disbursement as cash you received. Every fee in an exchange falls on one side of this line, and getting it wrong is the most common way investors accidentally create a taxable event.
Real Estate Closing Costs
The biggest dollar amounts in any exchange are the ordinary closing costs on the two transactions. They dwarf the exchange-specific fees, and they split into two piles based on how the IRS treats them.
Costs You Can Pay From Exchange Proceeds
Expenses tied directly to transferring the deed count as allowable exchange expenses. Real estate commissions are the largest line — the national average total commission in 2026 runs around 5.7% of the sale price, with a typical range of 5% to 6%. On a $500,000 sale, that’s $28,500 in commissions before anything else. Title insurance premiums, escrow fees, attorney closing fees, recording fees, and state or local transfer taxes also qualify because they attach directly to the sale or purchase itself.
On the sale side, these costs come out of the sale proceeds before the QI takes custody of what’s left. On the purchase side, exchange funds can cover the purchase-side closing costs. Either way, paying from exchange proceeds reduces the net amount you need to reinvest, which is how the mechanics are supposed to work.
Costs You Must Pay Out of Pocket
Recurring costs of owning or operating the property don’t qualify. Pay them from exchange proceeds and the amount becomes taxable boot. The usual suspects:
- Prorated property taxes owed at closing
- Property insurance premiums, whether transferred or newly initiated
- Utility prorations and HOA dues
- Maintenance reserves or escrow holdbacks for property condition issues
You need separate funds at the table for these items. The closing agent will itemize them on the settlement statement, so the numbers won’t surprise you on the day. What can surprise you is not having the liquidity to cover them, which is when investors get tempted to dip into exchange proceeds and create boot.
Tax Advisor, Attorney, and Form 8824 Fees
Structuring an exchange correctly takes professional help. A CPA or tax attorney reviews the identification strategy, projects depreciation recapture, and keeps you clear of the two hard deadlines: 45 days to identify replacement properties and 180 days to close.2Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment CPAs who specialize in real estate exchanges typically bill $300 to $500 an hour for that work. If you need an attorney to set up an LLC or other ownership structure for the replacement, initial setup runs $2,500 to $5,000.
Unlike QI fees, tax advisory and legal fees generally aren’t considered exchange expenses attached to the transfer of title. Pay them from exchange proceeds and you’ll create boot. Cover them with separate funds.
For rental property, these advisory costs are usually deductible as business expenses on Schedule E, which takes some of the sting out.
Form 8824 at Tax Time
After the exchange closes, you file Form 8824 with your return for the year you transferred the relinquished property. The form reports the exchange, calculates the deferred gain, and sets your basis in the replacement property. Related-party exchanges require Form 8824 for the following two years as well.3Internal Revenue Service. Instructions for Form 8824 (2025)
CPA fees to prepare a 1031 return, including Form 8824 and updated depreciation schedules, generally run $1,500 to $3,500. Simple single-property swaps land at the low end; multi-asset or partial exchanges push higher. This is a separate expense from the pre-exchange planning consultation.
Financing Costs and the Mortgage Boot Trap
If you’re borrowing to buy the replacement, lender fees pile on. Loan origination typically runs 0.5% to 1% of the loan amount — $2,000 to $4,000 on a $400,000 mortgage. Discount points (each equal to 1% of principal), application fees, underwriting fees, and the mandatory appraisal follow.
None of these financing costs qualify as exchange expenses. They relate to obtaining a loan, not transferring the property, so paying them from exchange proceeds creates boot. Bring separate funds for the entire lender package.4Internal Revenue Service. Publication 551 (12/2025) – Basis of Assets
For investment property, loan origination fees and discount points aren’t deductible in the year you pay them. You amortize them over the life of the loan.4Internal Revenue Service. Publication 551 (12/2025) – Basis of Assets Cash out now, tax benefit later.
Keeping Debt in Balance
The debt on the replacement has to equal or exceed the debt relieved on the relinquished property. A $350,000 mortgage paid off on the old property and only a $300,000 mortgage on the new one leaves you with $50,000 in mortgage boot. You can offset that by putting another $50,000 in cash on the table. Investors moving from a higher-leverage property to a lower-leverage one often underestimate how much extra cash they’ll need to maintain parity. Run the numbers with your CPA before you’re at the closing table.
Reverse and Improvement Exchanges Cost More
Not every exchange follows the sell-first, buy-second sequence. When the timing runs the other direction or the replacement needs work done, costs jump.
Reverse Exchanges
In a reverse exchange, you buy the replacement before selling the old one. You can’t hold title to both during the exchange, so an Exchange Accommodation Titleholder (EAT) takes title to the new property and parks it until the relinquished property sells. EAT fees typically run $6,000 to $10,000, and complex deals go higher. One national firm charges a flat $8,000 for reverse intermediary services. Layer on the fact that you’re often carrying two mortgages at once and closing on a compressed timeline, and the premium over a forward exchange can easily hit $10,000 or more.
Improvement Exchanges
An improvement exchange (also called build-to-suit) lets you use exchange proceeds to fund construction or renovation on the replacement. The EAT holds title while the work is completed, and it all has to finish inside the 180-day window. EAT fees, construction coordination, and the tracking of disbursements make these pricier than forward exchanges. The EAT fee and other soft costs during construction do count toward the total reinvestment amount, which helps you meet the requirement to redeploy the full proceeds.
State Tax Costs
Federal deferral doesn’t automatically mean state deferral. Most states follow the federal rules, but several impose extra requirements or costs that catch investors off guard.
- Clawback provisions: California and others reserve the right to recapture deferred gain later when a property sold in-state is exchanged into an out-of-state replacement. Sell a California rental and buy in another state, and California may tax the deferred gain when you eventually sell the replacement.
- Non-resident withholding: Some states withhold from sale proceeds when a non-resident sells property in their borders. Rates vary, and filings often need approval days before closing. Miss the deadline and funds get tied up or the exchange gets delayed.
- Separate state filings: A handful of states require their own forms to recognize the deferral, on top of the federal return.
- Transfer taxes: Many states impose real property transfer taxes on the sale regardless of whether it’s part of an exchange.
Pennsylvania was long the outlier that didn’t recognize 1031 exchanges. Act 53 of 2022 changed that, bringing Pennsylvania into conformity for tax years beginning after January 1, 2023. As of 2026, all 50 states recognize 1031 exchanges at some level, though the specific rules and clawback provisions vary enough that a tax professional who knows your state is worth the fee.
What a Failed Exchange Costs
Miss the 45-day identification deadline or the 180-day completion deadline and the exchange is disqualified entirely.2Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment The QI releases the funds to you and the full capital gains tax comes due. No partial credit. The QI fee, advisory costs, and any legal work you already paid for still stand, and now the tax bill sits on top of them.
If the funds get released in a different tax year than the original sale, some investors can use the installment method to spread the gain across the years cash is actually received. That takes careful CPA planning and controls timing, not liability. The QI cancellation fee still applies.
The most common reason exchanges fail isn’t the market, it’s the 45-day identification clock. Those are calendar days, and the only extensions come from a presidentially declared disaster. Experienced investors start scouting replacement properties before the relinquished property is even listed.
