When Seller Financing Makes Sense

For buyers

• You cannot qualify for a conventional mortgage (self-employed, low credit, recent bankruptcy)
• You want to avoid bank fees, appraisals, and lengthy approval processes
• You want creative terms like interest-only periods or lower down payments
• You are buying from a motivated seller who owns the property free and clear

For sellers

• You want to spread capital gains tax over multiple years (installment sale)
• You want passive income from the monthly payments at a higher return than bonds or savings
• Your property is not selling through traditional channels
• You have a wrap mortgage opportunity where you can earn the rate spread

Understanding Balloon Payment Risk

The balloon payment is the biggest risk in seller-financed deals. When it comes due, the buyer must either pay it in full, refinance into a conventional mortgage, or negotiate an extension with the seller. If interest rates have risen or the buyer's credit has not improved, refinancing may be difficult or expensive.

Before entering a seller-financed deal, have a clear plan for the balloon. Know what credit score and income documentation you will need to refinance. Build equity during the loan term so you have enough for conventional financing when the balloon comes due.

How Seller Financing Works — A Step-by-Step Example

A buyer purchases a $180,000 property with seller financing. The seller requires 10% down ($18,000), leaving a financed amount of $162,000. The note carries 6.5% interest, amortized over 30 years, with a 5-year balloon payment.

This is the core tradeoff of seller financing with a balloon: monthly payments are manageable, but the buyer builds equity slowly. After 5 years of payments totaling $61,440, the buyer has only reduced the principal by about $10,300. The remaining $151,656 must be paid in a lump sum — usually by refinancing into a conventional mortgage.

Typical Seller Finance Terms

Seller-financed deals are negotiable, but most fall within predictable ranges. These benchmarks reflect what lenders, attorneys, and title companies see in practice.

A seller who owns the property free and clear has the most flexibility on terms. If the seller still has a mortgage, the terms must at minimum cover the seller's existing payment, which limits how creative the structure can be.

Wrap Mortgages Explained

A wrap mortgage (wraparound mortgage) lets the seller finance the buyer while keeping the existing mortgage in place. The buyer's new note "wraps around" the seller's old one. The buyer makes one payment to the seller, and the seller continues making payments on the original loan.

How the spread works

The seller profits from the rate spread between the buyer's note and the existing mortgage. If the seller's original loan is at 3.5% and the buyer's note is at 7%, the seller earns the 3.5% difference on the full wrap amount — not just the equity portion. On a $162,000 wrap with $100,000 remaining on the original mortgage, the seller earns the spread on all $162,000 while only owing 3.5% on the $100,000 balance.

When wraps make sense

• The seller has a low-interest mortgage they want to keep in place (especially sub-4% rates from 2020-2021)
• The seller wants cash flow from the rate spread rather than a lump-sum sale
• The buyer cannot qualify for conventional financing but can afford the monthly payment
• The property has enough equity to give the seller a meaningful cushion against default

Risks to understand

The biggest risk is the due-on-sale clause on the seller's existing mortgage. If the lender discovers the transfer and calls the loan, the full balance becomes due immediately. Other risks: the seller could stop making payments on the underlying mortgage even while collecting the buyer's payment, and the buyer has no direct relationship with the original lender. A loan servicing company that handles payment collection and distribution reduces these risks significantly. Both parties should have separate legal counsel review the wrap agreement.
