Seller Financing vs Bank Financing: What Changes for the Seller

By Hans Goldstein · Updated 2026-09-27

For the seller, the difference between seller financing and bank financing is when you get paid and who you depend on afterward. With a bank loan, the buyer's lender pays you in full at closing: your risk ends that day, and all the gain is taxed that year. With seller financing, you become the lender: the gain spreads over the years you collect principal under §453, and you earn interest, but you carry the buyer's default risk, early payoff risk and the servicing for years.

There is also a third path many sellers do not know about: the buyer uses a normal bank loan and pays in full, and you still spread the gain with a structured installment sale set up before closing. This page compares all three from the seller's side.

The short answer in one table

Cash from a bank loan Seller note (you carry the loan) Bank loan + structured sale
What you get at closing The full price The down payment The full price is paid; you keep what you want in cash and the rest funds your schedule
Who owes you after closing Nobody The buyer An assignment company
Gain taxed in year of sale All of it The down payment's share (§453) The share on the cash you keep (§453)
Buyer default or foreclosure Not your problem Your problem Not your problem
Early payoff n/a Buyer can refinance or sell, which accelerates your tax Not possible
Interest rate you earn Whatever you reinvest in Usually higher Usually lower
Servicing and paperwork None after closing Note, deed of trust, collection, tax and insurance tracking Contract language and assignment documents before closing; nothing to collect after
Speed and deal risk Appraisal, underwriting and lender approval can delay or kill the deal Often faster; you set the terms Same as a bank deal
Liquidity later Full Low: a note usually sells at a discount None: the schedule is fixed

The rest of this page walks through each row.

Price and speed: the case for seller financing

Seller financing can widen the buyer pool. Buyers who cannot qualify for a bank loan, whose credit is thin, or who want to close quickly may be able to buy from you when a bank would say no. That can support your asking price, and a buyer who needs your terms is often less aggressive on price. It is a common reason owners of land, small rentals and small businesses offer terms.

A bank deal adds the bank's process. The buyer's lender will want an appraisal, underwriting of the buyer, title work and sometimes environmental or business-valuation reports. If the appraisal comes in low, the loan shrinks and the deal has to be renegotiated or the buyer brings more cash. The payoff is certainty on closing day: once the loan funds, you are paid and done.

Seller financing moves the underwriting to you. You decide whether the buyer is creditworthy. There is no appraisal gate, but there is also no bank checking the buyer's income and history on your behalf. If you finance, ask for what a bank would: credit report, tax returns, bank statements and a real down payment.

Taxes: all at once, or as you are paid

This is where the two paths differ most.

A bank-financed sale is a cash sale for tax purposes. The bank pays the buyer's loan proceeds to you at closing. You have received the full price in the year of sale, so all of the gain is taxed that year. An installment sale requires at least one payment after the close of the tax year of the sale (§453(b)(1)), and a bank-funded closing has none.

A seller note is an installment sale. The buyer's own note is not treated as a payment when you receive it (Temp. Reg. §15a.453-1(b)(3)(i)). You report gain as principal comes in: each principal dollar carries the same share of gain, the gross profit ratio. See seller financing taxes.

What does not spread under either path:

Simple example: year-one tax three ways

Simple example (illustrative). You sell for $1,000,000. Your adjusted basis is $400,000, so the gain is $600,000 and the gross profit ratio is 60%. No depreciation recapture and no mortgage to pay off. The buyer has $250,000 to put down. For illustration, apply a flat 23.8% federal rate (the 20% top capital gain rate plus the 3.8% net investment income tax); your real rate depends on your brackets. Closing is late in the year, so the first annual principal payment falls in the next tax year.

A. Bank loan. The bank lends $750,000, and you receive $1,000,000 at closing. All $600,000 of gain is taxed in year one.

B. Seller note. You take $250,000 down and carry $750,000 at 7% for ten years, $75,000 of principal a year plus interest on the declining balance.

C. Bank loan plus structured sale. The buyer pays $1,000,000 at closing with the same bank loan. You keep $250,000 in cash, and $750,000 funds a structured installment sale paying $75,000 of principal a year for ten years, at an illustrative 4.5% (actual payout rates are set when the structure is funded and reflect the commission built into pricing).

A. Bank loan B. Seller note C. Bank loan + structured
Cash in hand at closing $1,000,000 $250,000 $250,000
Gain taxed in year one $600,000 $150,000 $150,000
Federal tax in year one at 23.8% $142,800 $35,700 $35,700
Gain taxed each later year $0 $45,000 $45,000
Interest over ten years (before tax) n/a $288,750 $185,625
Who you depend on after closing Nobody The buyer The assignment company

The math: $250,000 × 60% = $150,000 of gain in year one, and $75,000 × 60% = $45,000 in each of the next ten years. Interest runs on balances of $750,000, $675,000 and so on down to $75,000, which add up to $4,125,000 of balance-years: 7% of that is $288,750 and 4.5% is $185,625.

B and C spread the gain identically. Spreading it can also keep more of it out of the top bracket and under the net investment income tax threshold in each year, which a flat-rate example does not show. The differences are the rate, and who is on the other side of the payments.

Risk: what you take on when you carry the note

With a bank loan, the buyer's credit is the bank's problem. With a seller note, it is yours.

Simple example, continued. In option B, the buyer refinances after three principal payments and pays off the remaining $525,000. At 60%, $315,000 of gain lands in that one year instead of $45,000 a year for seven more years.

Yield: note interest vs reinvesting the cash

A seller note usually pays a higher rate than a bank CD or a bond, and that is one of the real benefits of seller financing for the seller. Compare it honestly, though: the note's rate is paying you to take a single buyer's credit risk and to give up liquidity. A bank-financed sale lets you reinvest the whole price wherever you choose, but the reinvested amount is smaller because you paid the full tax in year one. The calculator runs both on your numbers.

Liquidity and paperwork

Bank financing: one closing, one check, nothing to manage afterward.

Seller financing: a promissory note, a deed of trust or mortgage, a recorded lien, title insurance, a servicing plan (or a servicing company), annual interest reporting, and tracking the buyer's property taxes and insurance. If you need cash later, you can sell the note, usually at a discount, and the sale triggers the deferred gain (§453B). The note value calculator shows what a note buyer might pay.

Spreading the gain when the buyer pays in full

Most sellers want two things that seem to conflict: a buyer who pays in full at closing with a normal bank loan, and the tax spread that seller financing gives. A structured installment sale gives both. The buyer closes with conventional financing and pays the full price. Before closing, the contract directs part of the price to an assignment company, which takes on the obligation to pay you on the schedule you pick (level, stepped, deferred start or a balloon). You report gain under §453 as you are paid, the same way you would on a seller note.

What drops out: buyer default, foreclosure, servicing, and an early payoff that dumps the deferred tax into one year. What stays: settled installment-sale law and a fixed schedule.

Seller note Structured installment sale
Buyer pays at closing The down payment only The full price, with a bank loan if the buyer wants
Tax on the deferred portion As principal is paid (§453) As payments are received (§453)
What backs the payments A lien on the property you sold, subordinate to any bank loan The assignment company's promise, funded by an annuity it owns. You hold no lien on the annuity or the building.
Default and foreclosure Your risk and your cost No buyer after closing
Early payoff Buyer can prepay, which accelerates the tax Not possible
Rate Usually higher Usually lower
Flexibility You can renegotiate or sell the note (a sale triggers the tax under §453B) None: the schedule cannot be changed, sold or pledged
Servicing You collect and track Nothing to collect

Seller financing still fits some deals well: a buyer you know, a large down payment, a situation where you may want to renegotiate, or a deal that cannot happen any other way. When the buyer can get a bank loan, though, the structured sale lets you keep the tax spread without becoming the lender.

What to know before you choose it. It has to be set up before closing; a note you already hold cannot be converted. The payments are locked in: you can't speed them up, borrow against them, pledge them or cash them out, and that is what keeps the deferral intact. There is no free look after closing: once the sale closes, the structure cannot be undone. The payments depend on the assignment company's ability to pay. The structure rests on settled installment-sale law, but this specific assignment structure has no published IRS ruling, so have your CPA or tax attorney review the documents. A commission is built into the pricing: Hans is paid about 2.4% of the amount structured, only if a structured sale is funded; seller financing pays him nothing (see the disclosures).

Bottom line

A bank-financed sale buys certainty: you are paid in full at closing and the risk is gone, but the whole gain is taxed that year. Seller financing buys tax spreading and a higher rate, paid for with the buyer's credit risk, early payoff risk and years of servicing. If what you really want is the tax spread, you do not have to be the lender: a structured installment sale written into the contract before closing lets the buyer use a bank loan while you are paid over time. Decide before the contract is signed, because afterward the choice is gone.
