JB PARCELSeller Financing Calculator
Owner financing lives or dies on the balloon. Set the price, the carry rate, the amortization, and the balloon term, and see the payment, the payoff due, and the date it lands.
How this calculator works
A seller-financed note is a normal amortizing loan with an early exit. The payment is calculated over a long amortization, usually thirty years, so the monthly stays affordable. But the note matures at the balloon date, and the entire remaining balance is due in one payment. On a thirty-year amortization with a five-year balloon at seven percent, you will have paid off less than seven percent of the principal when the balloon hits.
That is the whole point of the structure. The seller gets a steady return and a defined exit. You get in with less cash, no bank underwriting, and a rate that is often negotiable in ways a bank rate is not. What you take on is a deadline.
The interest-only option in Advanced options is worth asking for. A twelve-month interest-only runway on a value-add property lets the rehab and lease-up finish before the full payment starts. Sellers who care mainly about yield often agree, because their interest income is unchanged.
Two structural warnings the calculator flags for you. If the seller has an existing mortgage, you are building a wrap-around and the underlying lender's due-on-sale clause is live. And federal rules under Dodd-Frank and the SAFE Act limit owner financing on owner-occupied residential property. Neither is a reason to avoid seller financing, but both are reasons to use a real estate attorney rather than a form off the internet.
Worked example: a small Nashville-area multifamily
$295,000 price, $44,250 down (15 percent), seller carries $250,750 at 7 percent, amortized over 30 years, balloon at 60 months.
| Monthly payment | $1,668.25 |
|---|---|
| Payments made over 5 years | $100,095 |
| Principal paid down | $14,715 |
| Balloon due in month 60 | $236,035 |
| Seller collects in total | $380,380 |
Five years of payments knocked $14,715 off a $250,750 note. The other $85,380 was interest. If you cannot refinance or sell by month 60, you are negotiating an extension from a weak position, so start that conversation in year four.
Questions investors ask
Why would a seller ever agree to carry the note?
Three real reasons. They get a better yield than a CD or a bond with the property as collateral. An installment sale can spread the capital gain across years instead of taking it in one. And on a property a bank will not finance, tired, vacant, unusual, or land, carrying paper is often the only way to get their price. Free-and-clear owners who have held a long time are the best candidates, and you can find them on the parcel map by owner tenure.
What happens if I cannot pay the balloon?
You refinance, you sell, or you negotiate. Most sellers would rather extend than foreclose, but you are negotiating from a weak spot and they know it. Ask for a written extension option in the original note, even one that costs a fee or a rate bump, and it costs you almost nothing to have and everything to be without.
Is owner financing legal in Tennessee?
Yes, and it is common on investment property. The complications are federal, not state. Dodd-Frank and the SAFE Act restrict how often an individual can seller-finance owner-occupied residential property and impose ability-to-repay requirements. Investor-to-investor deals on non-owner-occupied property generally sit outside those rules, but the analysis is fact-specific. Use a real estate attorney, not a template.
Should I use a loan servicer?
Yes, for about $20 to $40 a month. A third-party servicer collects the payment, tracks the amortization, handles escrow, and issues the 1098 and 1099 at year end. It removes every argument about what was paid and when, and if either side later sells the note, a clean servicing record makes it worth more.
How do I get a seller to consider it?
Lead with what they get rather than what you need. A free-and-clear seller looking at a $295,000 sale is usually comparing your offer to a lump sum they have to reinvest. Show them the total collected over the note and the interest rate they earn while secured by a property they already know. Print this page and hand it to them.
