It's the most common pushback to the SIS structure: "If I'm OK getting paid over 10 years, why bring an insurance carrier in at all? I'll just have the buyer pay me directly. Cuts the carrier out." There are 10 reasons that move almost always goes badly for the seller of a real-estate or business asset.

Who do you trust more: an assignment company funded by a fixed annuity from a highly rated, heavily regulated life insurer, or the buyer's ability to keep paying you over the entire term?
That's the trust gap the SIS structure exists to close.
Think about the last house you sold. The buyer got a mortgage. The bank wired you the full purchase price at closing, not the buyer. You walked away with the check. You never followed up monthly to make sure the buyer was still paying their mortgage on time. You didn't worry about whether they'd lose their job in year 12 and default. That entire 30-year credit-risk problem was the bank's, not yours.
That's the role the assignment company plays in an SIS, just funded the opposite direction. The assignment company takes the buyer's lump-sum at closing (same as a mortgage bank takes the borrower's loan funds) and then makes the long-term scheduled payments back to you. The institutional middleman takes the buyer's place, so the buyer's credit risk is gone. What remains is the credit of the assignment company and the highly rated, heavily regulated life insurer behind its annuity. Direction of money flow is reversed; the architecture is the same.
The question stops being "do I trust the buyer to keep paying me for 25 years?" and becomes "do I trust an assignment company, funded by a fixed annuity from a highly rated life insurer, to keep paying me for 25 years?" For most sellers the second is the easier yes, for the same reason banks hold 30-year mortgages: yes, because the structural backstops are real.
A "buyer-financed installment sale", also called seller financing, an owner-carry note, or an installment land contract, is the original form of the §453 installment sale. The IRS has always allowed it. The structure works mechanically: buyer pays you over a period of years, you recognize gain proportionally, same gross-profit-ratio math the SIS uses.
But the §453 tax benefit is the easy part. The hard part is everything that can go wrong over 5, 10, 25 years with a real human (or LLC) on the other side of the obligation. The SIS structure was specifically engineered to keep the tax benefit and replace the buyer with an assignment company funded by a fixed annuity from a highly rated life insurer, eliminating almost every buyer-side failure mode of the traditional approach.
Below: the 10 ways buyer-financed installment sales tend to go wrong, and how the SIS structure handles each one.
Your buyer is a person or an LLC. Their financial-strength rating is "good enough to close this one deal." The life insurer whose fixed annuity funds an SIS is expected to be rated A or better by AM Best when the annuity is bought (a rating is an opinion of financial strength, not a guarantee, and it can change), and it is regulated by state insurance departments that set reserve requirements.
You wouldn't loan $1M to a stranger you'd known for 6 months, but that's mechanically what seller financing is. Even with a perfect-on-paper buyer at closing, you have no idea what their financial situation looks like in year 7.
Over 10 to 25 years, the buyer will likely experience some combination of: divorce, death, disability, lawsuit, bankruptcy, business failure, IRS lien, judgment creditor, family-court attachment, or simple disappearance. Each of these can interrupt or extinguish your payment stream. Even when you have a recorded mortgage or deed of trust on the property, recovery is slow, expensive, and uncertain.
A bankruptcy filing freezes everything. A divorce decree may split your note across two new payors. A buyer's estate may dispute the obligation. You go from passive income recipient to active litigant.
Receiving payments directly means: collecting payments, sending late notices, tracking late fees, preparing annual 1099-INT and Form 6252 information for the buyer, issuing demand letters when they're 30 days late, retaining a collection attorney when they're 90 days late, foreclosing if they default. This is unpaid administrative work that grows over time.
Plus the recordkeeping burden: you have to maintain the amortization schedule, the basis recovery calculations, the imputed-interest allocations under §483, and any §453B disposition events. One missed step and your installment treatment gets challenged on audit.
If the buyer stops paying and you have to foreclose, you're now the owner again of an asset that the prior owner has been depreciating, maybe under-maintaining, possibly tenanted with problem renters, possibly trashed. You're back at square one with legal fees, repair costs, and a fresh sale to run. And whatever depreciation recapture the buyer didn't recognize bounces back onto your books.
In a down market, which is exactly when buyers default, you may not be able to resell at the original price. The economic outcome can be much worse than just paying tax on the original sale.
Five years in, the buyer refinances at a better rate (or sells the property) and writes you a lump-sum check for the balance. Sounds nice. But that prepayment is treated as an "early disposition" of the installment obligation under §453B(a). You recognize all the remaining deferred gain in the year of the prepayment. The whole bracket-compression benefit you structured for collapses into one year.
You can refuse the prepayment if the note doesn't allow it, but most market-rate seller notes do. And refusing creates buyer ill-will, possible default, possible litigation.
Interest rates spike, the buyer's business hits a rough year, they ask to lower the payment for 18 months and extend the term. You either say yes (in which case you may trigger a §453B disposition by materially modifying the note) or you say no (in which case you risk default).
Even a "friendly" restructure usually involves a CPA, a lawyer, and three weeks of negotiation. If you say yes, your gain-recognition schedule gets messy and complicated.
If your buyer moves out of state (or out of the country), enforcement of the obligation becomes substantially harder. Wage garnishment, judgment liens, and bank levies all run through the state where the buyer is now located. Filing fees and attorney costs in another jurisdiction quickly exceed what you'd recover from a small monthly payment.
This is particularly bad for California sellers, where buyers commonly relocate to Texas, Nevada, or Florida after closing, all of which have buyer-friendly enforcement environments.
Five years in, you have a financial emergency and need a lump sum. Your seller note can be sold to a note-buying secondary market, but the sale triggers §453B disposition: all the remaining deferred gain is recognized in the year of sale, plus you'll take a 25-40% discount from the secondary buyer (the same "lump-sum penalty" that we walk through on the homepage). You eat the full Year-1 tax bill AND you sell the note at a steep discount. Worst of both worlds.
A seller note exists in a manila folder in your file cabinet (or a PDF on your laptop). The annuity is administered by a large, regulated life insurer with 24/7 support, online portals, automated direct deposit, fraud monitoring, audit trails, and decades of operational experience handling millions of structured-settlement payments. If something goes wrong with your seller note, there's no help desk to call. If something goes wrong with the carrier annuity, there's an entire department.
Offer to seller-finance and the financing becomes part of the deal: rate, down payment, term, prepayment rights, guarantees, what happens if the buyer resells. Some buyers pay more for your financing and some push for a lower price, but every term you concede is one you live with for years, on top of the 9 problems above.
Section 453 (the installment method) is the tax rule: when you are paid over time, you report the gain as the payments arrive. There are two ways to be paid over time. The tax math is the same; the risks are not.
| Seller financing (carry-back note) | Structured installment sale | |
|---|---|---|
| Tax rule | §453 installment method | §453 installment method, if the structure holds |
| Legal footing | Settled: the textbook installment sale | A reasoned position; no IRS ruling specifically approves the assignment structure |
| Who owes you | The buyer | An assignment company, funded by a fixed annuity it owns from a highly rated life insurer |
| Security | Deed of trust on the property | None: you are an unsecured creditor of the assignment company |
| Buyer default | Possible: foreclosure, bankruptcy stay, repossession | None: the buyer is out at closing |
| Buyer pays off early | Possible: the remaining gain is taxed at once | Not possible |
| Cash early if you need it | Sell or pledge the note, and the deferred gain is taxed at once (§453B, §453A(d)) | No cash-out, loan, pledge or acceleration |
| Rate | Usually higher | Usually lower |
| Servicing | You | None |
| Commission | None | Built into the annuity pricing |
Which risks you would rather hold is your decision. Review it with your own CPA and attorney before closing.
The obvious "exception" most people think of is a related-party sale: selling to your kids, a sibling, a long-trusted business partner, or a family LLC. The 10 problems above feel mitigated by the relationship: you know the buyer's financial situation, you trust they won't default, you're often happy to renegotiate if circumstances change, you're not particularly worried about state-line enforcement against your own family. The financial risk profile drops.
But family seller-financing carries a different and arguably bigger risk: relationship damage if anything goes wrong. If your son loses his job in year 8, your sibling's business hits a bad year, or your in-law's marriage falls apart, you're choosing between two painful options:
A lot of family-financed sales end in one of these two outcomes. The Thanksgiving table never quite recovers from (a). Option (b) corrodes the relationship from a different angle. Use family seller-financing at your own risk. Even when the financial logic looks airtight, the relationship-cost calculation is usually worse than it appears at the kitchen-table moment when everyone agrees the deal is "fine."
The SIS structure can actually keep family relationships cleaner by removing you as the lender entirely. Your kid (or sibling, partner, etc.) pays cash at closing like any other buyer. The assignment company owes you the payments over 25 years. There's no debtor-creditor relationship between you and your family. No awkward "did you make the payment this month?" conversations at Christmas. Neither of you holds anything over the other. The family transaction looks like any other arms-length sale on paper, with the relationship preserved on the side.
(This leaves aside the §453 mechanics every related-party case still needs: the §453A interest charge on installment obligations over $5M, the §453(g) special rules for related-party transactions, the 2-year resale lookback under §453(e), and the imputed-interest rules. A CPA and tax attorney still need to be involved either way.)
For arms-length sales to unrelated buyers, which is 95%+ of real-estate and business sales, the SIS structure exists specifically to keep the §453 tax benefit while eliminating the buyer-as-counterparty risk. That's why structured installment sales evolved from the traditional installment sale model in the first place.
The SIS structure was built specifically to give you the installment-method bracket compression without making you the lender. Want to walk through whether SIS or a traditional seller-carry fits your specific case?

It can be when the buyer is strong, the down payment is large and you want interest income. It also widens the buyer pool and can help close a deal. The cost is credit risk for the life of the note: if the buyer stops paying you may have to foreclose and take the asset back, and a §1038 repossession has its own tax consequences.
Buyer default, bankruptcy or death can interrupt payments; you service the loan yourself; the buyer may prepay, which ends your deferral and taxes the rest of the gain; renegotiating terms can trigger a disposition under §453B; and selling the note for cash also triggers the deferred gain. Recapture under §453(i) is still due in year one even if the down payment is small.
A seller-financed sale is an installment sale under IRC §453, reported on Form 6252 each year. The note must carry at least the applicable federal rate or interest is imputed under §483 or §1274. Depreciation recapture is taxed in the year of sale, disposing of the note triggers the remaining gain under §453B, and sales to related parties who resell within two years can accelerate gain under §453(e).
Get a meaningful down payment, run a credit check, record a deed of trust or mortgage, require insurance and tax escrows, add a due-on-sale clause and personal guarantees, and charge at least the applicable federal rate. Or remove the credit risk: in a structured installment sale the buyer pays in full at closing and the payments are owed by an assignment company, subject to the claims-paying ability of the issuing insurer.
