The pre-buy inspection and the loan are two parts of the same purchase, and they need to be coordinated. Lenders generally require a pre-buy on a used aircraft before funding, its timing affects your closing, and its findings can change the deal. This page covers how the pre-buy fits into financing; for the inspection itself, see our pre-buy inspection guide.
Key takeaways
- Lenders require a pre-buy on used aircraft before funding, to protect their collateral.
- Timing matters — schedule it early so it doesn't delay closing.
- The buyer usually pays for the pre-buy as a transaction cost.
- Findings can change the deal — price, terms, or whether it closes.
Why Lenders Require It
Because the aircraft is the lender's collateral, they want confirmation of its condition before advancing funds. A pre-buy inspection verifies the airplane is airworthy and free of major undisclosed problems, protecting both you and the lender from a bad deal. On most used-aircraft loans the pre-buy is effectively mandatory; the lender wants to know the collateral is sound. It's not a hurdle to resent — it's the same protection you'd want as a buyer.
Timing the Pre-Buy in the Loan Process
The pre-buy sits between your accepted offer and closing, and it's often the schedule bottleneck — a good shop may be booked out, and turbine or jet inspections take longer. Schedule it as early as possible after your purchase agreement (which should include an inspection contingency), and make sure your loan timeline and the agreement's windows account for it. Coordinating the inspection, the appraisal, and underwriting is where deals either close on time or slip.
Who Pays, and How Findings Affect the Deal
The buyer typically pays for the pre-buy as a transaction cost, separate from the loan. What it finds can reshape the deal: a clean report clears the way to close; minor squawks may become seller-corrected items or a price adjustment; and major findings can justify walking away under your inspection contingency — or cause the lender to reconsider terms if the aircraft's value or airworthiness is in question. This is exactly why the inspection contingency and a thorough pre-buy matter so much.

On used aircraft, generally yes — the lender wants confirmation the collateral is sound before funding. It also protects you from a bad deal, so it's worth doing regardless.
Who pays for the pre-buy inspection?
The buyer typically pays, as a transaction cost separate from the loan. It's usually the largest single cost outside the aircraft and any taxes.
How does the pre-buy affect my closing timeline?
It's often the bottleneck — good shops book out and turbine inspections take longer. Schedule it early and make sure your purchase agreement and loan timeline account for it.
What if the pre-buy finds problems?
Minor squawks may become seller-corrected items or a price adjustment; major findings can justify walking away under your inspection contingency or cause the lender to reconsider terms.
