Seller Financing Balloon Amortization Calculator 2027
Calculate seller-financed mortgage with balloon payment 2027 — 30-year amortization with 5/7/10-year balloon. Common for owner-financed real estate deals.
Seller Financing Mechanics
Seller acts as bank. Buyer makes monthly payments to seller. Common when: buyer can't qualify traditional, seller wants high interest return, deal needs to close fast, no appraisal.
Balloon Payment Risk
Balloon = lump sum due at end of short term. If buyer can't refinance/sell, faces foreclosure. Smart buyers plan refi at year (balloon-1). Smart sellers require 20-25% down + due-on-sale clause.
Tax Implications (Installment Sale)
IRS Section 453 allows seller to spread capital gain over years of payments. Lower yearly tax than lump-sum sale. Doesn't apply to dealer property or stock-in-trade.
Dodd-Frank Restrictions
Owner-occupant residential seller financing: 1 deal per 12 months without licensing. More than 1 = lender license required. Investment-to-investment deals unrestricted.

Frequently Asked Questions
What if buyer can't make balloon?
Options: refi with bank, sell property and pay seller from proceeds, negotiate extension (rare), foreclose. Seller usually wins — either gets paid or gets property back + kept payments.
What rate to charge?
Negotiation. Usually 1-3% above bank rates (8-10% in 7% market). High enough to compensate seller for risk + tax timing benefit.
Need a real estate attorney?
Yes. Promissory note + mortgage/deed of trust must be drafted properly. Recording mortgage protects seller. DIY = high risk of unenforceable terms.
