Tool 01 Seller-Carry Payment Calculator

What will the buyer pay you — and what's left at the balloon?

Enter the price, down payment, rate, and term. You'll get the monthly payment, the total interest, the balloon amount if there is one, and a schedule you can print or download.

A seller-carry note works like a bank loan, except you are the bank. The buyer pays you principal and interest each month, and a recorded trust deed secures the note.

The payment uses the standard amortization formula. The rate is whatever you and the buyer agree to in writing: Utah has no usury cap on an agreed rate, and the legal rate without an agreement is 10% (Utah Code § 15-1-1). For tax purposes, a rate below the applicable federal rate can cause interest to be imputed (26 U.S.C. §§ 1274, 483).

A balloon means the buyer owes the remaining balance in one payment, usually by refinancing. Whether a balloon is allowed depends on which federal seller-financer exclusion you fit — the licensing checker walks through it. A person, estate, or trust financing one property may use a balloon (12 CFR § 1026.36(a)(5)); the three-property exclusion requires full amortization (12 CFR § 1026.36(a)(4)).

The payment shown is principal and interest only. Property taxes, insurance, and any servicing fee come on top.

After 84 payments the buyer owes $347,262 in one lump sum. Most buyers plan to refinance to pay it. If they can't, you're the one holding a defaulted note — plan the exit before you sign.
