Why it exists
Seller financing solves real problems on both sides. For the buyer, it bypasses bank qualification — no DTI ratios, no income verification, no 45-day underwriting, no property-condition rejection. For the seller, it creates a broader buyer pool, typically justifies a 5–10% price premium, generates ongoing interest income, and spreads capital gains tax across the note term under IRC §453.
The use cases range from free-and-clear properties whose owners want income without the stock market to distressed properties where traditional financing won’t work to investor-to-investor deals where both sides prefer creative structure to the bank’s timeline.
The three primary structures
- Purchase Money Mortgage (PMM) — the cleanest structure. Seller owns the property free and clear and finances the balance after buyer’s down payment. Buyer takes title subject to a new first mortgage in favor of the seller. No underlying loan to worry about, no due-on-sale complications. Most common on fully-paid-off properties.
- Wrap-Around Mortgage — buyer takes title subject to seller’s existing mortgage, and the seller “wraps” a new, larger loan around it. Buyer pays the seller; the seller continues paying the original lender. Buyer benefits if the underlying rate is below-market (the seller keeps the spread). Creates due-on-sale exposure on the underlying loan.
- All-Inclusive Trust Deed (AITD) — functionally similar to a wrap, consolidated into a single note and deed of trust at a blended interest rate. Popular in California. Seller still manages the underlying loan; buyer sees one unified payment.
Typical terms
- Down payment — 10–25%. Higher down reduces seller risk; lower down favors buyer but justifies a higher interest rate.
- Interest rate — 6–10% is typical, often 1–3 points above prevailing conventional rates to compensate seller for illiquidity and default risk.
- Amortization — 20–30 years for monthly affordability, matching traditional mortgage amortization.
- Balloon— 5–10 years is the standard seller-financed structure. Limits seller’s long-term exposure; forces buyer to refinance or resell.
- Escrow for taxes and insurance — often bundled into the monthly payment so the seller can verify the property’s taxes and insurance are current.
Worked example. $600,000 sale; 10% down ($60,000); $540,000 financed at 7%, 30-year amortization, 5-year balloon. Monthly payment ≈ $3,593. Balloon payoff at 60 months ≈ $508,000. Terms are negotiable — prepayment penalties, interest-only periods, and step-up rates are common variations.
The documents
- Promissory note — the buyer’s unconditional promise to pay principal, interest, late fees, and default remedies. Governed by UCC Article 3. Must specify: principal, rate, term, payment amount and date, grace period, default triggers, acceleration clause, prepayment terms, attorney-fee provision, and governing law.
- Deed of trust / mortgage — the security instrument recorded against the property. Puts the world on notice that the seller has a lien. Must be recorded with the county recorder/register of deeds in the property’s county. Form varies by state (deed of trust in non-judicial states; mortgage in judicial).
- Settlement statement — reflects the down payment, the seller-financed balance, prorations, and transfer taxes. Handled through escrow or title company like any closing.
- Occupancy affidavit — buyer attestation of intended use (owner-occupant, rental, flip). Drives Dodd-Frank analysis.
Professional practice: use a real estate attorney to draft the note and security instrument. Templates from generic legal sites frequently miss state-specific enforcement requirements and can render the note difficult to collect on default.
Dodd-Frank and the SAFE Act
The Dodd-Frank Act (implemented via Regulation Z, 12 CFR §1026.36) and the SAFE Act regulate residential mortgage originators. Seller financing of an owner-occupied residential property (1–4 units) triggers these rules unless the seller qualifies for a narrow exception.
Two important exceptions for individual sellers financing their own properties:
- 3-property-per-year exception — a seller who finances no more than three owner-occupied properties in a 12-month period is exempt from loan-originator licensing. The note must still be fully amortizing (no negative amortization), have a fixed rate for at least 5 years, and meet the ability-to-repay provisions.
- 1-property-per-year “natural person” exception — a single seller financing one owner-occupied property can skip even the ability-to-repay analysis, provided the note meets certain payment structure requirements (no balloon within 5 years, fixed rate or adjustable with specific limitations).
Investor-to-investor deals are exempt. If the buyer signs an affidavit that the property will be non-owner-occupied (rental, flip, vacation home), Dodd-Frank does not apply. Most seller-financed investor deals rely on this exclusion and always collect the occupancy affidavit at closing.
Violating Dodd-Frank without a valid exception creates severe exposure: civil penalties, rescission rights for the buyer (they can unwind the transaction), and potential criminal referral. Professional practice: never finance owner-occupant residential without confirming the exception applies and documenting the analysis.
Installment sale tax treatment (§453)
Section 453 of the Internal Revenue Code allows a seller to report gain on an installment sale proportionally as payments are received, rather than recognizing the full gain in the year of sale.
Gross Profit Ratio = (Sale Price − Basis) ÷ Contract Price Gain Per Payment = Principal Received × Gross Profit Ratio
Example. Basis $400,000; sale $600,000; down $60,000; financed $540,000. Gross profit = $200,000; ratio = $200K ÷ $600K = 33.3%. Year 1 principal received = $60K down + ~$10K amortized principal = $70K. Gain recognized in Year 1 = 33.3% × $70K = $23,333. Interest received is separately taxable as ordinary interest income.
Installment sale treatment spreads the capital gain across the note term, typically keeping the seller in lower brackets than a lump-sum sale would. Not available for dealer property (inventory) or publicly traded securities. Doesn’t defer depreciation recapture under §1250 — that’s still owed in the year of sale.
The due-on-sale clause and wrap exposure
Virtually every institutional mortgage contains a due-on- sale clause under the Garn-St. Germain Act (12 U.S.C. §1701j-3). The clause lets the lender accelerate the loan — demand the entire balance due — if title transfers without lender consent.
PMM on free-and-clear property has no due-on-sale issue. Wrap-around mortgages and AITDs do. When the seller holds an underlying institutional loan and “wraps” the buyer’s purchase around it, the title transfer technically violates the underlying loan’s due-on-sale clause.
Lender detection mechanisms:
- Title search during refinance, insurance policy transfer, or property sale
- Payment anomalies (different return address, different bank account)
- Property tax reassessment notifications
- Insurance policy changes with new named insured
Professional wrap investors mitigate by transferring title into a revocable living trust (protected under Garn-St. Germain exceptions), maintaining continuous insurance in the seller’s name, keeping the original bank account for payments to the lender, and moving quickly toward refinance. Lender enforcement is discretionary and historically uncommon while payments are current — but the risk is always present.
Buyer perspective — when it beats a bank
- Close in 14 days vs. 45–60 for a conventional loan
- No qualifying — bypasses DTI, credit minimums, income documentation
- No appraisal — or only a streamlined one
- Distressed-property eligible — works on properties a bank will reject (needs work, non-conforming, mixed-use)
- Lower upfront costs — no origination fee, minimal underwriting fees
- Negotiable terms — everything’s on the table
The buyer’s responsibility: exit strategy. Most seller-financed notes carry a 5-year balloon. The buyer must be ready to refinance into conventional financing, sell the property, or negotiate an extension by then. Investors who BRRRR this structure refinance into a DSCR loan after stabilization.
Seller perspective — the exit
- Higher sale price — 5–10% premium justified by financing access
- Installment-sale tax deferral — gains spread across note term
- Ongoing interest income — 6–10% yield secured by real estate
- Larger buyer pool — includes buyers unable to qualify conventionally
- Retained security — if buyer defaults, seller can foreclose and reclaim the property (keeping down payment and all prior principal received, minus foreclosure costs)
The seller’s responsibility: vetting the buyer. Professional sellers require a credit check, employment verification, reserve documentation, and a meaningful down payment (15%+) to ensure the buyer has skin in the game. A sub-10% down seller-financed deal is a foreclosure waiting to happen.
Default and foreclosure
If the buyer stops paying, the seller’s remedy is foreclosure — exactly like a bank. The process, timeline, and redemption rules are governed by state law, not the seller-bank relationship. See the judicial vs. non-judicial reference for state-by-state mechanics.
Most seller-financed note holders use a professional loan servicing company (NoteServ, Allied Servicing, FCI Lender Services) to handle collections, escrow, and reporting. The servicer’s monthly fee is typically $15–30 per loan and buys the seller proper documentation if foreclosure becomes necessary.
Common pitfalls
- Dodd-Frank non-compliance. Financing an owner-occupied residence without confirming a valid exception exposes the seller to civil penalties and rescission. Always document the exception analysis at closing.
- Low down payment. Sub-10% down on a seller-financed deal is an invitation to default. The buyer walks away; the seller inherits a property in worse condition than sold. Professional sellers require 15% minimum.
- Balloon without exit plan. 5-year balloons arrive fast. Buyers who can’t refinance end up in foreclosure; sellers end up inheriting the property back. Both sides should document the expected exit path at closing.
- Due-on-sale surprise on wraps. An underlying lender can call the wrap any time. Plan for it. Have refinance capacity in reserve.
- Inadequate note documentation. DIY notes miss state-specific enforceability requirements. Foreclosure takes 6 months longer and costs 3x more than it should. Invest $1,500 in a real estate attorney.
- No loan servicer. Self-managing payments creates disputes about what was paid when, poor tax reporting, and weak foreclosure evidence. Use a servicer.
- Subordination traps. Agreeing to subordinate the seller’s note to a future buyer refinance can leave the seller with a worthless second lien if the new first lender forecloses. Don’t sign blanket subordination agreements.
