1031 Exchanges and Seller Financing: How Buyer Notes Affect Your Plan

By Jerry Baker

Seller financing can be part of a 1031 exchange, but a buyer’s promissory note is not qualifying replacement real estate. You may be able to exchange part of the sale and report gain tied to the note over time under the separate installment-sale rules. The plan needs to address both the tax treatment and the cash you will actually have when the replacement purchase closes.^[1][2][3]

Are you lending money or borrowing it?

The phrase “seller financing” can describe two very different roles. If you sell your building and let the buyer pay you later, you become the lender. If you acquire a replacement building and its seller lets you pay later, you become the borrower. Start there. A plan that works on one side of the transaction cannot simply be copied to the other.

On the sale side, a note is a promise to pay. Even when a mortgage secures it, owning the note does not mean you own the building for Section 1031. The federal real-property regulation excludes notes and other evidence of debt from qualifying real property.^[1]

On the purchase side, you might receive the actual qualifying property and owe its seller money. That financing may help fund the purchase. Your tax adviser must still review the exchange, the amount of debt, the cash used, and the closing terms. The source of a loan does not excuse the other exchange rules.^[2]

I would put the two roles on separate lines of the worksheet: “money someone owes me” and “money I owe someone.” Mixing them together can make a cash shortage look like a completed plan.

Two kinds of deferral can operate together

Section 1031 concerns an exchange of qualifying real property held for business or investment. It can postpone gain when you receive qualifying replacement property and follow the rules. A fully taxable sale followed by an unrelated purchase does not become an exchange just because the amounts match.^[2]

Section 453 concerns when eligible sale gain is reported as payments arrive. An installment sale generally requires at least one payment after the tax year of the sale. Some sales and some types of gain do not qualify. You can also elect out of the installment method.^[3]

These rules answer different questions. The exchange rules ask what you received for the property. The installment rules ask when eligible gain tied to payments must be reported. A note can fail the first test as replacement property while still receiving installment treatment under the second.

That is why “the note is boot” does not always mean the whole note produces tax immediately. Boot is money or other nonqualifying property received in an otherwise qualifying exchange. Gain outside Section 1031 may still be reported under Section 453 if the note and transaction meet its requirements. The IRS addresses this combination directly.^[4][5]

An example: replacement property plus a buyer’s note

Consider this hypothetical transaction. It is an illustration, not a client result or a suggested structure. Assume qualifying investment land, no old loan, no selling costs, no recapture, unrelated parties, and all required exchange steps completed on time.

• Sale value: $1,000,000.
• Adjusted tax basis: $400,000.
• Buyer pays $800,000 in cash and gives a $200,000 note.
• The properly arranged exchange uses the cash to acquire $800,000 of qualifying replacement property.
• You ultimately receive that property and the buyer’s $200,000 note.

The total gain is $600,000: the $1,000,000 value less the $400,000 basis. Under these simplified facts, $400,000 of gain remains deferred under Section 1031. The remaining $200,000 relates to the note and does not qualify for exchange nonrecognition.

Assume the note has adequate stated interest, is not payable on demand or readily tradable, and qualifies for installment reporting. Also assume no principal payment is received or treated as received in the sale year. The installment contract price is $200,000 after subtracting the replacement property. The installment gross profit is also $200,000 after subtracting the exchange-deferred gain. That makes the gross profit percentage 100%.

If the buyer pays $40,000 of principal in a later year, all $40,000 is reported as installment gain in this example. Interest is reported separately. The percentage is not the 60% you would get by dividing the original $600,000 gain by the entire sale price. The combined exchange and installment rules change the calculation.^[3][4]

This example scales the basic cash-plus-note situation addressed in the deferred-exchange regulation. It assumes the note is handled through the qualified intermediary, or QI, under a proper agreement. It is not a rule that every personally received note gets the same result.^[5]

Compare a sale without a 1031 exchange

Now consider a separate hypothetical sale of investment land for $1,000,000 with a $400,000 basis. Again, assume no debt, costs, recapture, or special rules. This time you receive a $200,000 down payment and an $800,000 buyer’s note. You acquire no replacement property through an exchange.

The $600,000 gross profit divided by the $1,000,000 contract price gives a 60% gross profit percentage. Of the $200,000 down payment, $120,000 is gain and $80,000 recovers basis. A later $50,000 principal payment includes $30,000 of gain and $20,000 of basis recovery. Interest stays separate.^[3][8]

The payment schedule may spread eligible gain across years, but it also leaves you dependent on the buyer. You have exchanged a property for cash and a loan asset. There is no replacement-property income in this example, and you no longer receive that property’s future appreciation as its owner.

I would compare the two plans using after-tax cash, credit risk, liquidity, and work required. Looking only at the first year’s tax can hide a much bigger difference in what you will own afterward.

Build the purchase budget from cash, not face value

Suppose the buyer’s offer is $2 million: $1.4 million in cash and a $600,000 carryback note. Ignore costs and existing debt just to see the funding problem. Your sale price may be $2 million, but the closing has only $1.4 million in cash.

A replacement seller who wants cash cannot pay its own bills with the face value written on your note. If you plan a $2 million purchase, you must show how the other $600,000 will be funded. More borrowing, your own cash, or a different negotiated transaction may address the funding gap. None automatically resolves the tax treatment of the note you receive.

Use two separate schedules. One tracks actual funds: bank balances, buyer cash, approved loan proceeds, and when each becomes available. The other tracks tax items: value transferred, basis, liabilities, replacement property, and any money or note received. Your CPA and QI should reconcile both.

If someone proposes adding your own cash, selling the note, or assigning it within the exchange, ask for the exact sequence in writing. Who receives the original note? Who owns it during the exchange? What does the replacement seller receive? What value is assigned to it? Who reports any discount or gain? A funding solution is not a tax opinion.

Agree on the note before the first closing

The federal QI safe harbor depends on an exchange agreement, the intermediary’s role in the transfers, and restrictions on your access to exchange assets. Sending money to a company called an intermediary after a normal sale is not enough. The regulation contains an example where missing transfer arrangements cause that result.^[5]

Bring proposed financing terms to the QI and your attorney while the sale is being negotiated. Confirm whether the QI will handle a note at all. Its willingness to hold cash does not tell you its policy on debt documents, collateral, assignments, servicing, or collection.

The closing instructions should name the correct payee and recipient of each asset. They should also explain any later transfer of the note. Tax counsel needs to review the substance, not simply approve a label such as “exchange note.”

Make the buyer’s obligations clear, too. A buyer might assume it can delay its down payment or change the note’s maturity after signing. Either change may affect your funding plan. I would want the people drafting the sale contract and the people managing the exchange working from the same written terms.

A long note does not give you a longer exchange

The normal deferred-exchange clock starts when you transfer the relinquished property. Replacement property generally must be identified within 45 days. You generally must receive it by the earlier of 180 days or the due date of your tax return for that sale year, including an extension. The two periods run from the same starting transfer.^[2]

A five-year buyer note does not give you five years to select replacement real estate. Later note payments do not restart those deadlines. An early payoff may improve cash availability, but it does not repair missed identification or turn an already completed taxable sale into a deferred exchange.

A plan that depends on the buyer refinancing before your exchange expires needs a fallback. What if the appraisal is lower? What if the buyer’s lender requires more documents? What if the loan is approved but funds arrive after the replacement closing cutoff?

I would ask for evidence of the funding source and a realistic closing schedule. A buyer’s hope of getting a loan is not the same as cleared funds. Leave room for bank, escrow, and document cutoffs rather than treating the legal deadline as the time to begin wiring.

The note’s terms affect taxes and collections

Under Section 453, the buyer’s ordinary promise to pay generally is not itself a payment. A note payable on demand or readily tradable receives different treatment. Simply printing “installment note” on a document does not settle that question.^[3]

Interest needs separate attention. An agreement with too little stated interest may require some stated principal to be treated as interest or original issue discount. Applicable federal rates change monthly. Use the rules and rates for the actual transaction instead of copying a rate from an old example.^[8]

For the credit review, I would want clear answers about the borrower, collateral, payment dates, maturity, and what happens after a default. Ask counsel to assess lien priority, other debt, guarantees, insurance, taxes, and enforcement under applicable law. Those are review questions, not promises that collateral will cover a loss.

Separate interest from principal in your income plan. Principal payments give your invested capital back, including any taxable gain component. Spending the entire payment as though it were ongoing yield can leave you with less capital after the note matures.

Some gain cannot wait for the payments

Ordinary depreciation recapture under Sections 1245 or 1250 generally must be reported in the sale year under Section 453(i), even when no installment principal arrives that year. The rest of eligible gain may be reported over time. This matters when a sale includes assets with accelerated depreciation.^[3][4]

Do not treat every depreciation-related gain amount as identical. Ordinary recapture and unrecaptured Section 1250 gain are different categories. Have the CPA separate the components before predicting when they are taxable. A worksheet that applies one gain percentage and one tax rate to every dollar can miss the issue.

Related-party sales need added review. Section 453 has rules for sales of depreciable property to certain related parties and for a related buyer’s later disposition. Section 1031 also has its own related-party rules. Satisfying one section does not mean you have satisfied the other.^[2][3]

Existing debt can change the installment calculation, too. Do not subtract the old mortgage from the sale price and call the remainder your taxable profit. The IRS provides special rules for assumed debt and debt above basis. The examples here leave debt out so the basic distinction remains clear.^[4]

Selling or borrowing against the note can change the result

A note you own may be worth less than its unpaid balance. Its buyer may demand a discount for credit risk, the interest rate, or the time before repayment. A $300,000 face amount does not prove someone will pay $300,000 in cash.

Disposing of an installment obligation can also trigger gain. Section 453B generally compares the amount realized, or fair market value in certain transfers, with your basis in the obligation. Selling a note is not automatically a continuation of the original installment schedule.^[6]

For example, assume an owned note has a $200,000 unpaid balance and a 60% remaining gross profit percentage. Its basis is $80,000. If it is sold for $170,000 under a straightforward taxable sale, the resulting gain is $90,000. The $30,000 discount from face value does not mean the transaction produces a $30,000 tax loss. Other facts can change the calculation.^[6]

Borrowing against an installment note requires its own review. Section 453A can treat loan proceeds secured by an installment obligation as a payment. It also imposes interest on deferred tax for certain large installment obligations. Thresholds, exceptions, and aggregation rules matter. Do not assume that calling the cash a loan makes a monetization plan tax-free.^[7]

Compare the whole plan before accepting the offer

I would compare at least three versions of a sale proposal: an all-cash closing, a partial exchange with a note, and an installment sale without an exchange. They may involve different prices or buyers. Put the terms side by side so a larger headline price does not hide weaker cash or credit terms.

• Cash available: How much is available at closing, after costs and debt?
• Replacement budget: Which funds can actually reach the next closing on time?
• Tax schedule: What is deferred through the exchange, reported over time, or taxable now?
• Income: How much of each payment is interest, principal, or property cash flow?
• Downside: What happens if the buyer misses payments or cannot refinance?
• Exit: What would it take to sell, collect, or settle the note?

Then run a slower-payment case. Assume the balloon payment is delayed and legal or servicing costs rise. Would you still have enough cash for taxes and spending? Would you be comfortable managing collections? The attractive version of a note is easy to describe. The difficult version deserves space on the same page.

My role is to help evaluate replacement investments and how they fit your needs. Your attorney, CPA, and QI need to resolve the note structure and tax reporting. I would rather work from a funded, documented plan than recommend investments based on money that may never reach the exchange account.

Keep a file that explains both transactions

Keep the sale contract, note, security documents, closing statements, exchange agreement, assignments, identification notice, and proof of replacement acquisition. Add a record of when the QI received each asset and when you received any money or note.

After closing, keep principal and interest records separate. Give the CPA the initial transaction documents as well as annual payment statements. Form 6252 is generally used for installment-sale reporting; exchange reporting and other gain forms may also apply. A loan servicer’s statement does not replace the tax calculation.^[8]

Update the adviser team before forgiving debt, selling the note, changing its terms, or transferring it. Those actions can create tax questions beyond collecting the scheduled payments. The original closing plan is a starting record, not permanent approval for every later change.^[6]

Frequently asked questions

Can I receive a buyer’s note and still do a 1031 exchange?

Potentially. A properly arranged transaction can include qualifying replacement property and a buyer’s note. The note does not qualify for Section 1031 nonrecognition, but eligible gain tied to it may receive installment treatment. The QI agreement, note terms, timing, and other tax rules must be reviewed together.^[3][5]

Does a mortgage make the note qualifying real estate?

No. A loan secured by real estate is still a debt asset. The federal regulation excludes notes and other evidence of debt from real property for Section 1031. The collateral may matter to your collection risk without changing the note into replacement property.^[1]

Is the whole note taxable as soon as I receive it?

Not necessarily. A qualifying buyer note generally is not a payment when received under Section 453, and eligible gain can be reported as payments arrive. Demand notes, readily tradable notes, ordinary recapture, and other exceptions can change that result. Exchange treatment and installment timing are separate questions.^[3]

Can I exchange the note itself for another property later?

A note itself is not qualifying Section 1031 real property. Selling or otherwise disposing of an installment obligation can trigger gain under Section 453B. Do not assume you can receive a note now, hold it for years, and later exchange it as though you still owned the original building.^[1][6]

Does seller financing extend my 45-day or 180-day deadline?

No. A buyer’s repayment schedule does not extend the ordinary deferred-exchange periods. The replacement purchase must meet its own deadline, including the earlier tax-return due-date rule where applicable. Plan the funding separately from when you expect the buyer to repay its note.^[2]

Can the replacement property’s seller finance my purchase?

Potentially. In that role, you receive property and owe the seller money. That is different from receiving a note when you sell. The debt and cash must be included in the exchange calculation, and the transaction must still satisfy the property, timing, and other requirements.^[2]

Is interest part of the deferred capital gain?

Interest is generally ordinary income reported separately from installment gain. Inadequate stated interest can cause part of stated principal to be treated as interest or original issue discount. Have the CPA review the interest provisions and applicable federal rates when the documents are prepared.^[8]

What should I do before agreeing to carry a note?

Ask your attorney, CPA, and QI to review a written plan showing the borrower, note recipient, security, payment schedule, replacement funding, and expected tax treatment. Compare it with a cash sale. Accept the credit and liquidity risks only if the overall plan works for you, including a realistic delayed-payment case.

Educational information, not an offer or a personal tax, legal, or investment recommendation. Examples are hypothetical and omit stated adjustments. Tax treatment depends on your facts and current law. Review your transaction with your CPA, attorney, and qualified intermediary. Real estate investments can lose value and may be illiquid.
