If you've been exploring creative finance, you've probably heard of both seller financing and subject-to deals. They sound similar — both let you buy (or sell) real estate without traditional bank financing. But they work very differently, carry different risks, and are better suited to different situations. This guide puts them side by side with real numbers so you can make the right call for your deal.
Quick definitions
Seller financing (owner financing)
The seller becomes the bank. Instead of the buyer getting a mortgage from a lender, the seller carries a note. The buyer makes monthly payments (principal + interest) directly to the seller. The existing mortgage is paid off at closing (or the property is owned free and clear). A new deed of trust secures the seller's note.
Subject-to (sub-to)
The buyer takes title to the property subject to the existing mortgage. The mortgage stays in the seller's name. The buyer makes payments on the existing loan. No new financing is created — the buyer simply takes over the existing debt. For a deeper dive on subject-to mechanics, see our complete subject-to guide.
The side-by-side comparison
| Feature | Seller Financing | Subject-To |
|---|---|---|
| Existing mortgage | Paid off at closing (or property is free and clear) | Stays in place — buyer takes over payments |
| New note created? | Yes — seller carries a new note | No — buyer pays the existing note |
| Who holds the risk of loan default? | Seller (as lender) if buyer stops paying | Seller (loan is still in their name) if buyer stops paying |
| Interest rate | Negotiated (typically 6-10% in 2026) | Whatever the existing mortgage rate is (often 3-5% from 2020-2022) |
| Down payment | Negotiated (typically 5-20%) | Negotiated (often smaller — just covering seller's equity) |
| Due-on-sale risk | None — existing mortgage is paid off | Yes — lender could call the loan due |
| Tax treatment for seller | Installment sale (IRC 453) — spread gains over time | Capital gain recognized at closing (equity received) |
| Seller's credit exposure | None — original mortgage is gone | Ongoing — mortgage stays on seller's credit until paid off |
| Best for sellers who... | Want recurring monthly income, want to defer capital gains, own the property free and clear or have small balance | Need fast exit, have low equity, want to preserve their low interest rate as a selling point |
| Best for buyers who... | Can't qualify for bank financing, want to negotiate terms, have a meaningful down payment | Want the lowest possible interest rate, want to maximize cashflow, have less capital for down payment |
When seller financing is the better choice
For the seller
Scenario 1: You own the property free and clear. This is the ideal seller-finance situation. You have no underlying mortgage to worry about. You carry a note at 8%, collect monthly payments, and earn interest income for 10-30 years. If the buyer defaults, you foreclose and get the property back (plus keep the down payment and all payments made).
Example: You own a rental property worth $300,000 with no mortgage. You sell it via seller financing:
- Sale price: $290,000
- Down payment: $30,000 (10%)
- Note: $260,000 at 8%, 30-year amortization with a 7-year balloon
- Monthly payment to you: $1,907
- Total received over 7 years before balloon: $30,000 down + ($1,907 × 84 months) = $190,188
- Remaining balance at balloon: ~$242,000 (buyer refinances and pays you this lump sum)
- Total received: $462,188 on a $300,000 property
Compare that to a cash sale at $285,000 minus 6% commission ($17,100) = $267,900 net. Seller financing generates $194,288 more over 7 years. The trade-off is time and risk — but for sellers who don't need all the cash now, the math is compelling.
Scenario 2: You want to defer capital gains tax. Under IRC Section 453, an installment sale (which seller financing qualifies as) lets you recognize gains proportionally as you receive payments, rather than all at once. If you're selling a property with significant appreciation, this can save tens of thousands in taxes.
For the buyer
Scenario: You're self-employed with strong income but weak credit documentation. Banks want 2 years of W-2s or clean tax returns. If you're a 1099 contractor, business owner, or recent immigrant without a US credit history, seller financing bypasses the bank entirely. You negotiate terms directly with the seller.
When subject-to is the better choice
For the seller
Scenario 1: You're behind on payments and facing pre-foreclosure. You need someone to take over the mortgage now — before the foreclosure auction. A cash buyer might lowball you. An agent sale takes 60-90 days (you don't have that time). A sub-to buyer takes title in 10-14 days and starts making your mortgage payments immediately. Your credit is protected; the loan stays current.
Scenario 2: You have low equity but a great interest rate. Say you owe $270,000 on a house worth $290,000 at 3.5%. A cash sale barely covers your mortgage payoff after closing costs. Subject-to lets a buyer take over that 3.5% loan (which is worth its weight in gold in a 7% rate environment), and they pay you a smaller cash amount for the equity — $10,000-$20,000 — rather than forcing a payoff that leaves you with nothing.
For the buyer
Scenario: You want maximum cashflow and the lowest possible payment. A subject-to deal at 3.5% on a $270,000 balance = $1,212/month P&I. That same property with a new loan at 7% = $1,796/month P&I. The sub-to deal puts $584/month more in your pocket from day one. Over a year, that's $7,008 in additional cashflow — with zero additional capital invested.
Real example: same property, two structures
Let's take a real scenario from our Houston pipeline and model both structures on the same house:
Property: 3-bed/2-bath in Missouri City, TX. ARV: $310,000.
Seller situation: Relocating to Atlanta. Owes $220,000 at 3.75% (FHA from 2021). Wants $40,000 cash.
Structure A: Subject-to
- Buyer takes over the $220,000 mortgage at 3.75%
- Buyer pays seller $40,000 cash for equity
- Monthly mortgage payment: $1,019 P&I + $580 T&I = $1,599
- Rental income: $2,400/month
- Monthly cashflow before management: $801
- After 10% PM fee ($240): $561/month net cashflow
- Cash invested: $40,000
- Cash-on-cash return: 16.8%
Structure B: Seller financing (if property were free and clear)
Hypothetical: assume the seller owned this property outright and wanted $290,000 with seller financing.
- Down payment: $30,000 (10%)
- Note: $260,000 at 8%, 30-year amort, 7-year balloon
- Monthly payment to seller: $1,907 P&I + $580 T&I = $2,487
- Rental income: $2,400/month
- Monthly cashflow before management: −$87 (negative!)
- After PM fee: −$327/month
This illustrates the key difference: subject-to gives the buyer the existing low rate, which makes cashflow work. Seller financing creates a new note at a market rate, which often kills cashflow on properties with existing debt. Seller financing works best when the seller owns the property free and clear and can negotiate a below-market rate.
The risks compared
Seller financing risks
- Buyer default: If the buyer stops paying, the seller must foreclose to recover the property. In Texas, this takes ~60 days (non-judicial). In judicial states, it can take 6-12 months.
- Property damage: If the buyer neglects the property, the seller may get back a damaged asset. Mitigation: require property insurance naming the seller as additional insured.
- Balloon risk: If you include a balloon payment and the buyer can't refinance at the balloon date, you're stuck renegotiating or foreclosing.
Subject-to risks
- Due-on-sale clause: The lender could call the loan due. Rare when payments are current, but possible. Mitigation: have refinance or payoff capital available.
- Seller's credit exposure: The loan stays on the seller's credit report. If the buyer misses payments, it hits the seller's score. Mitigation: use a third-party servicer with monthly payment confirmation to the seller.
- Seller's future borrowing: The existing mortgage counts against the seller's debt-to-income ratio for future loans. This can prevent them from buying their next home with conventional financing.
How Afiyah structures both
We use both strategies regularly — the right tool depends on the deal. Here's our standard approach:
For subject-to acquisitions
- Third-party loan servicer (FCI Lender Services) handles all payments — creates a verifiable paper trail
- Monthly payment confirmation emailed to the seller automatically
- Property insurance maintained with the lender and seller listed
- Seller gets a clause allowing them to reclaim the property if payments miss by 30+ days
- All documents reviewed by a Texas real estate attorney
For seller financing deals
- Licensed RMLO (Residential Mortgage Loan Originator) involved for owner-occupant sales (Dodd-Frank compliance)
- Title company handles closing and deed recording
- Promissory note and deed of trust drafted by attorney — no internet templates
- Third-party servicer collects payments (we never handle buyer payments directly)
- Hazard insurance and property tax escrow built into the payment
Which should you choose?
Use this decision tree:
- Does the property have an existing mortgage with a low rate (sub-5%)? → Subject-to is likely better for the buyer. The rate advantage is too valuable to pay off.
- Is the property owned free and clear? → Seller financing is the natural fit. The seller becomes the bank and earns interest.
- Does the seller need maximum cash at closing? → Neither creative structure is ideal — a cash sale may be better. But if the seller needs some cash + ongoing income, seller financing with a down payment works.
- Is the buyer's primary goal maximum monthly cashflow? → Subject-to (existing low rate) usually produces better cashflow than seller financing (new higher rate).
- Does the seller want to completely exit the transaction? → Seller financing is cleaner — the original mortgage is paid off, and the seller has no ongoing lender exposure. Subject-to leaves the seller's name on the loan.
