I sold a house in Marana last April and agreed to carry the note because the buyer had a real down payment and I was not in a hurry for the lump sum

The pattern you are describing is one of the most common places a seller-financed note catches people off guard: the balloon was designed around your plan, but its execution depends on the buyer's ability to refinance, which you do not control.

A quick definition first. A balloon means the remaining principal balance comes due all at once on a set date, even though monthly payments were calculated on a longer schedule, here 20 years. So when 2027 arrives, the buyer owes roughly $110,000 or so in one payment rather than just the next $980.

Your position is actually stronger than it might feel. Twenty-four percent down means your loan-to-value (the loan amount as a share of the property's value) started at about 76 percent. If the property has held its value, your collateral cushion is real. A performing buyer with that kind of skin in the game has strong reasons to find a way to refinance, because they lose a meaningful down payment if they walk.

The thing worth thinking through now, before 2027, is whether your note is structured to sell if you need liquidity and the buyer cannot refi. A seasoned, performing note with a healthy LTV can be sold to a note buyer at a discount, meaning you get a lump sum now but less than the full remaining balance. How much less depends on the rate, the seasoning, the LTV, and the buyer's payment history. That is a real exit, and it does not require waiting on the buyer to qualify.

I would also have a direct conversation with a note broker now, not in 2026, so you know what that lump sum would actually look like as an option. That number will change how you think about extending versus selling.

What is your rough read on the property's current value, and do you know whether the buyer has been building credit since the sale?

The assumption doing the most work in your original structure is that balloon + 5 years = buyer qualifies for conventional financing in 2027. That was never in your control, and it still is not. Your attorney is right that a modification is procedurally simple, but that framing undersells the decision you are actually making.

Here is what the modification changes structurally. You extended a 20-year amortization at 8.5 percent with a balloon at year 5. If the buyer cannot refi and you extend the balloon, you are now deciding the new balloon date, whether to adjust the rate, and whether the amortization schedule resets or continues. Each of those is a negotiation with someone who has no other option, which means you will likely accept terms closer to yours, but you are still granting an extension as a concession. Confirm the exact modification mechanics and any required documentation with your attorney before that conversation starts.

The risk you have not named directly is the appraisal gap. You wrote "probably needs an appraisal," which I read as you are not certain what the property is worth today. Your cushion at origination was roughly 24 percent. If the Marana market has softened or the property condition has drifted, that cushion may be narrower than you think. The buyer's ability to refi is partly on their credit, but also partly on whether a lender will lend 80 percent of today's appraised value against your outstanding balance. Get an independent BPO or appraisal now, before the balloon conversation, so you are negotiating from a known LTV position.

On the note sale side: a 24-month seasoned, performing note at 8.5 percent with a 24 percent original down payment is a reasonably attractive asset to a note buyer. If you want the lump sum before the balloon resolves, selling the note at a discount is a real option. The discount will eat into your yield, but it is a liquidity path that does not depend on the buyer refinancing. Confirm current note-buyer pricing with a note broker to understand the spread.

What does your modification agreement draft actually say about rate adjustment at extension?

The risk your attorney is not pricing for you is the appraisal gap, not the buyer's credit. If that property appraises below the remaining balance in 2027, a conventional lender will not close the refi regardless of how clean the buyer's payment history is, and you end up extending not because you chose to but because the math forced you. Marana has had enough new construction activity that comps can move in ways that hurt a 2019 or 2020 purchase price anchor.

The thing worth doing right now, two years out, is pulling the county assessor's current value estimate and running a rough 80 percent LTV test against your projected remaining balance. If those numbers are tight, you want to know that in 2025, not in a balloon-due letter exchange in 2027 when your options compress.

What is your approximate remaining balance today, and do you have a sense of what that property would appraise at if you had to guess?

Two years out is actually the right time to be asking this, because you still have enough runway to shape the outcome rather than react to it. The tell I watch in this situation is not whether the buyer has been on time, which you have, but whether they have been building any financial complexity that conventional underwriting will penalize. Self-employment income that started after origination, a divorce, a second property with its own debt service, a credit card balance that crept up because payments to you felt like the priority. Any one of those can disqualify someone who has a clean payment history on your note and a real equity cushion. The $38k down plus two years of amortization at 8.5 percent on a 20-year schedule means they have paid down roughly another $9-10k in principal, so they are sitting on close to $50k of equity in a Marana property that has probably appreciated since April of last year. That equity protects you if they default and you foreclose, but it does not get you to the refi unless a lender will count it. Have a direct conversation with your buyer now, not in 2026, and ask them to pull their own credit and share the report informally. If something is wrong, you want 24 months to work with it, not 6.

The thing your attorney is technically correct about but structurally underselling is that an extension is simple to execute and complicated to price. If you extend, you are choosing between leaving the rate at 8.5 percent, which a buyer in a tighter rate environment may actually prefer to a conventional loan, or resetting to market, which depending on where rates sit in 2027 could be above or below what you are earning now. An extension with a rate adjustment also gives you a negotiating moment to shorten the remaining amortization, which is how you compress
