Seller Financing: How Investors Use It to Buy More Properties
When the seller becomes the bank, the deal terms become whatever you negotiate. Here's when sellers say yes, how to structure the loan, and why this is one of the most underused tools in real estate.
Seller financing — sometimes called owner financing — is a deal where the property's seller acts as the lender. Instead of you getting a mortgage from a bank, you sign a promissory note directly to the seller and make payments to them every month. The seller holds the lien on the property until you pay it off.
For the right deal, this is the cheapest, fastest, most flexible financing in real estate. It is also wildly under-asked-for. Most buyers never even bring it up.
When Sellers Offer Seller Financing
Not every seller can or will do this. The seller has to own the property free and clear (or have enough equity to wrap their existing mortgage), and they have to want monthly payments rather than a lump sum. The right seller is usually one of these:
Free-and-clear property owners
An older landlord who paid off the property in 2010 and is tired of dealing with tenants. They have $250K of equity and no mortgage. If they sell traditionally, they walk away with $250K cash and a tax bill. If they seller-finance, they collect monthly income for the next 15 to 30 years.
Retiring landlords
The most common profile. A retiree who built a portfolio of rental properties wants steady passive income, not a lump-sum payout. Seller financing gives them a stream of monthly payments backed by the property they know intimately.
Sellers seeking tax benefits
The IRS allows installment sales — selling a property over multiple years instead of all at once — which spreads the capital gains tax across years. For a seller with a large gain, this can drop them into a lower tax bracket. The deductibility math is covered in detail at takehometax.com.
Properties that won't qualify for conventional financing
Major deferred maintenance, unusual zoning, mixed-use buildings, rural properties — anything banks struggle with. Seller financing skips the bank's underwriting box entirely.
Typical Seller Financing Structures
Down payment
5% to 30%, negotiable. Sellers prefer larger down payments because it reduces their risk. Buyers prefer smaller because it preserves capital. The middle ground is usually 10% to 20%.
Interest rate
Whatever the parties agree to. Common range: 5% to 8% — often below market because the seller's alternative is bank-savings rates. The IRS sets a minimum applicable federal rate (AFR) below which the IRS treats part of the payments as taxable gift income, so check current AFRs.
Amortization
Fully amortizing or partially amortizing with a balloon. A common structure: 30-year amortization with a 5-year or 7-year balloon. Lower monthly payment than a 5-year fully amortizing loan, but you have to refinance or pay off at year 5.
Term
3 to 10 years for most balloon structures. Some sellers will fully amortize over 15 to 30 years if they want lifetime income.
Prepayment
Negotiable. Some sellers want a lockout period (no prepayment for 2-3 years) so they collect their interest. Others welcome prepayment.
An Example Deal
Property listed at $250,000. Seller owns it free and clear. You negotiate: $250,000 purchase, 10% down ($25,000), seller-financed first mortgage of $225,000 at 6.5% interest, 30-year amortization, 7-year balloon.
Monthly payment: $1,422. Compare that to a conventional investment loan at 7.5% on the same balance: $1,572. Saving $150 a month, plus you avoided closing costs of $5,000+ and lender points of 1% to 2%.
At year 7, you owe a balloon of approximately $204,000. You refinance into a long-term loan at whatever rates are then available. Or you sell. Or you negotiate an extension. Run the refinance scenario at the calculators at mortgagemathlab.com.
Required Legal Documents
Seller financing has the same legal infrastructure as bank financing — and you cannot skip it. Required at closing:
Promissory note. The buyer's promise to pay. Specifies amount, rate, payment schedule, term, default consequences.
Mortgage or deed of trust. Recorded at the county. Gives the seller the right to foreclose if you stop paying.
Settlement statement (HUD-1 or closing disclosure). Itemizes the deal at closing.
Deed. Transfers ownership from seller to buyer at closing.
A title company or real estate attorney handles all of this for typically $1,000 to $2,500 — well below conventional closing costs.
The Due-on-Sale Clause Risk
If the seller still has a mortgage on the property, almost every conventional mortgage contains a "due-on-sale" clause: when the property is sold, the bank can demand the loan be paid off in full. Wrapping a seller financing deal around an existing mortgage (called a "wrap" or "AITD") triggers this clause.
In practice, banks rarely call loans due as long as payments are made on time. But the risk is real. Best practice: only do seller financing on properties owned free and clear, or work with a real estate attorney to structure the wrap properly.

Benefits to the Investor
No bank. No DTI calculations, no W-2s, no 6 weeks of underwriting. The deal closes in 2 to 3 weeks at a title company.
Flexible terms. Down payment, rate, amortization, balloon — all negotiable. You can structure it to fit your cash flow.
Lower closing costs. No origination fees, no points, no mortgage insurance.
Bypasses the 10-property cap. Seller financing does not count against your Fannie Mae limit. A scaling investor can use seller financing to keep buying after conventional doors close.
Possible below-market rates. When the seller's alternative is a money market account, even a 6% interest rate beats it.
Risks to Watch
Balloon payment. If you cannot refinance or sell at the balloon date, you can lose the property. Always have a refinance plan and a backup plan.
Title issues. Always get a full title search and title insurance. Sellers may not realize there are old liens on their property.
Servicing. Pay through a third-party loan servicer (typically $25-$50/month). This creates an audit trail of payments and avoids disputes.
Insurance and taxes. Make sure the deal specifies who pays property taxes and insurance and how that is escrowed.
How to Find Seller-Financed Deals
The fastest way: filter MLS searches for "owner financing" or "owner will carry" in remarks. Many off-market deals also work — direct mail to free-and-clear absentee owners, networking at REIA meetings, and asking on every conventional offer you make.
