A good starting point for a fair seller-financed interest rate is the current conventional mortgage. From there, the rate can be adjusted based on factors like the buyer’s down payment, the loan term, and the amount of risk the seller is assuming. In mid-2026, most fair seller-financed rates fell in the 7.5% to 9.5% range, though the right rate depends on the details of the deal.
What “fair” actually means in seller financing?
Fair doesn’t mean one fixed number. Fair isn’t a fixed figure, meaning there’s no published rate sheet for seller financing. Unlike a bank loan, the interest rate is negotiated between the buyer and the seller, which is why many investors struggle to figure out what’s fair.
Set the rate too high, and the buyer may walk away. Set it too low, and the seller may not earn enough to justify tying up their money for years. A fair rate doesn’t necessarily mean a fixed number. It means the deal should make sense for both sides. The seller should be able to compensate for the risk of carrying the loan. The buyer should be convinced that fair financing is more attractive than other options.
At the Mortgage Shop, we’ve seen many examples of seller-financed deals for vacation homes, short-term rentals, and long-term investment properties that usually fall within a range rather than one specific rate.
Start with the conventional rate, then add the premium
Since there is no published and fixed seller-financing rate to compare against, people often start with the conventional mortgage rate.
As of June 2026, a 30-year fixed-rate mortgage averages about 6.5% for well-qualified owner-occupants. Investment property loans generally come in a bit higher. From there, another 1% to 3% is usually added by sellers. This extra return is because they’re bearing the loan risk themselves, rather than passing it on to a bank.
The seller-financed accurate rate depends on the transaction details. The size of the down payment and how long the financing can stay in place are the two most important details affecting the rate.
A worked example
Here’s what that might look like in the real world. Imagine a seller who owns a vacation rental free and clear.
A buyer offers 20% down and asks for a seven-year seller-financed loan with a balloon payment. Conventional financing for investment properties is sitting around 7.5%, so the seller starts the negotiation at 9%.
The buyers probably won’t accept that number right away. They have two points to debate and negotiate: strong credit and putting money into the property as soon as they take ownership. From the seller’s point of view, that lowers the risk and improves the value of the collateral.
This process will lead to a little back and forth. Eventually they agreed around 8.25%. This isn’t because 8.25% is a more universally correct rate. It’s simply the number that both sides were comfortable with after weighing the risks and the terms of the deal.
How does the down payment move the rate?
Think of the down payment as part of the risk calculation. A buyer putting 30% down usually presents quite a different level of risk than someone putting down just 10%.
What about the seller’s perspective? More equity means the buyer is less likely to walk away if the property loses value or unexpected expenses come up. Because of that, a larger down payment often gives the buyer more room to negotiate.
A reduction of about 0.5% to 1% isn’t unusual, although every deal is different. There’s another reason sellers care about down payment.
If they ever have to foreclose or take the property back, the buyer’s equity provides a financial cushion. The smaller that cushion is, the more risk the seller accepts and the more likely they are to ask for a higher interest rate.
How does the term length move the rate?
The length of the loan matters since the seller is giving up access to that money for a certain period of time. That’s why a shorter note is often safer for sellers. This is the reason why they are willing to accept a lower rate.
For example, a five-year note with a balloon payment might be priced somewhere around 7% to 8% depending on the rest of the deal.
A longer setup, like a 15- or even 20-year amortization, often results in more costs as the seller’s money is tied up for longer. This explains why some investors prefer shorter seller-financed terms. They may plan to refinance into conventional or DSCR financing once the property is stabilized.
What’s pushing rates right now?
A seller and buyer negotiate the final rate. However, current market conditions shape where those conversations begin. The biggest influences are interest rates, inflation, and local supply and demand.
The federal funds rate is holding around 3.50% to 3.75% in late June 2026; conventional mortgages remain relatively expensive.
Sellers also factor in inflation, since their money may be tied up for years. One other number worth watching is the 10-year Treasury yield. Mortgage rates generally move in the same direction, which means seller-financed rates often do too.
The Art of Negotiation: Buyers and Seller’s Side
Buyer’s side
If you’re the buyer trying to talk the rate down, come with evidence, not just a request.
Bring comparable deals that show what other seller-financed notes in the area are going for. Point to improvements you plan to make that raise the property’s value, since that lowers the seller’s risk if they ever have to take the place back. And lean on your own credentials such as strong credit, real assets, a track record of finished deals. Every one of those makes you look less likely to default, and that’s what earns a lower number.
One thing buyers underuse: offering a larger down payment in exchange for a lower rate, then doing the math on which actually costs less over the life of the note. Sometimes trading cash up front for a better rate saves you far more than holding onto that cash, especially on a longer term.
Seller’s side
If you’re the seller, you have legitimate reasons to ask for a premium, and you should name them.
You’re offering something banks don’t: flexible qualification and speed. A buyer who can close in two weeks without a full underwriting gauntlet is getting real value, and that’s worth paying for. You can also use structure instead of just rate; an interest-only opening period or a graduated payment schedule helps a buyer manage early cash flow, which can justify a higher headline rate while still keeping the deal attractive.
Don’t overlook the tax angle either. Spreading the gain across an installment sale rather than taking one lump sum can soften your tax hit, and the interest income arrives steadily over years. For some sellers, that combination is worth more than getting cashed out at closing, which is part of why they’re willing to carry the note in the first place.
