Reading your transfer vs buyout result
Why transferring almost always costs less upfront
A transfer only requires paperwork and a modest processing fee, since the buyer simply steps into your existing contract and takes over the remaining payments. A buyout requires paying the system's estimated fair market value outright, which can run into the tens of thousands depending on how many years remain. That gap is why most sellers default to transferring when the buyer is willing and able. The DOE's homeowner's guide to solar financing covers lease structures in more general terms.
What the buyer is actually taking on
The buyer assumes the remaining monthly payments, including all future escalator increases, for whatever years are left on the contract. That's a real cost to disclose clearly during the sale, since a buyer unaware of a rising payment schedule can feel misled later. The PPA vs lease comparison explains how that escalator works if your buyer has questions about it.
When a buyout makes more sense despite the cost
If your buyer can't qualify for the lease assumption, doesn't want to take on the contract, or you're selling to a cash buyer who wants full ownership included, a buyout removes the friction entirely and can even become a selling point. It's also sometimes required if a buyer's mortgage lender objects to the lease attachment on the property. HUD's homebuying resources cover general lender and closing considerations that sometimes intersect with this exact issue.
How this compares to selling a home with an owned system
A home with an owned, paid-off solar system generally sells more easily than one with an active lease, since there's no contract to transfer or explain. If you're weighing whether to buy out before listing specifically to simplify the sale, compare that cost against your expected time on market and buyer pool using the system buyout value over time calculator. The home value increase from solar tool can help you quantify that resale advantage directly.
What to disclose to your buyer either way
Whether you transfer or buy out, disclose the solar arrangement clearly in your listing and purchase agreement. An undisclosed lease that surfaces during a title search or buyer's inspection can delay or derail a sale at a much worse time than addressing it upfront.
