Aircraft Appraisal for a Loan: When Lenders Require One, What It Costs and How It Sets Your Loan
This guide covers the lender's valuation of the aircraft you're financing: which kind of valuation you'll get, who pays, and how the number sets the loan.
Desktop valuation or formal appraisal: which will your lender use?
"Appraisal" gets used loosely. There are three levels, and which one your lender uses depends on the loan size, the aircraft and how well the price lines up with published values.
| Type | What it involves | When lenders use it | Cost (AOPA, 2017) |
|---|---|---|---|
| Pricing-guide valuation | A Vref or Aircraft Bluebook value for the model and year, adjusted for time and equipment | Routine purchases of common types where the price is near the guide value | Least expensive; often run by the lender |
| Desktop appraisal | An appraiser reviews records, photos, equipment and comparable sales without visiting the aircraft | When the lender wants a professional opinion but the aircraft is straightforward | About $500–$600 |
| Physical (on-site) appraisal | An appraiser inspects the aircraft and records in person and writes a full report | High-value, unusual, damaged or poorly documented aircraft; disputed values | About $2,000–$4,000 |

FLYING Finance describes the common practice this way: below roughly $1 million, many lenders size the loan against a desktop valuation pulled from an industry-standard pricing guide instead of ordering a full USPAP appraisal, but they reserve the right to require a full appraisal if the numbers don't line up or the aircraft has unusual equipment or history (FLYING Finance, Aug 2026). USPAP is the Uniform Standards of Professional Appraisal Practice, the standard formal appraisals are written to.
When is a formal aircraft appraisal required?
Lender policies differ, but these are the situations that most often trigger one:
- The price is well above guide values. The lender needs support for the gap, or it sizes the loan on the guide value.
- The aircraft is unusual. Rare models, vintage aircraft, experimentals and heavily modified aircraft have few guide entries or comps.
- Major modifications or a new panel. Guides may not capture a large STC package or recent glass panel, and the owner wants credit for it.
- Damage history or incomplete records. The appraiser has to decide how much to deduct. See missing logbooks and your aircraft loan.
- Refinance or cash-out. There is no arm's-length price to anchor the value.
- Large loan amounts, or a lender whose policy requires one regardless.
Who orders the appraisal and who pays for it?
The borrower usually pays, either upfront or as a closing cost. The lender usually orders the appraisal or approves the appraiser, because it needs the valuation to be independent of both buyer and seller. That has a practical consequence: an appraisal you commission yourself may not be accepted. If you want your own valuation for negotiating, ask the lender first whether it will rely on it or on an appraiser it chooses.
For formal work, look for an appraiser who writes to USPAP and holds an aircraft-appraisal credential (the National Aircraft Appraisers Association is one credentialing body), and who knows the type. The report belongs to the party that ordered it; ask for a copy.
How appraised value sets your loan: a worked example
Most lenders calculate loan-to-value on the lower of the purchase price or the appraised value. Take a $180,000 purchase, a lender maximum of 85% LTV (the 15% down payment AOPA lists for post-1960 singles), and an illustrative 8.00% rate over 20 years.
| Scenario | Price | Appraised | Loan basis | Max loan | Cash at closing | Monthly P&I |
|---|---|---|---|---|---|---|
| Plan: appraisal matches price | $180,000 | $180,000 | $180,000 | $153,000 | $27,000 | $1,280/mo |
| Appraisal comes in low | $180,000 | $165,000 | $165,000 | $140,250 | $39,750 | $1,173/mo |
| Seller cuts price to $170,000 | $170,000 | $165,000 | $165,000 | $140,250 | $29,750 | $1,173/mo |
| Seller cuts price to appraised value | $165,000 | $165,000 | $165,000 | $140,250 | $24,750 | $1,173/mo |
Principal and interest only; excludes the appraisal fee and other closing costs. Not a quote.
A $15,000 shortfall on the appraisal raises the buyer's cash from $27,000 to $39,750, an increase of $12,750. Notice that the loan stays the same in the last three rows: once the appraisal sets the basis, a price cut reduces your cash dollar for dollar but doesn't increase what the lender will lend. That's why the appraised value, not the negotiated price, is the number your financing is built on.
In a refinance there's no price to compare. If an aircraft appraises at $220,000 and the lender's refinance limit is 80% (an illustrative figure; cash-out limits are often tighter than purchase limits), the most you can borrow is $176,000, whatever you paid or owe. See refinancing your aircraft loan.
Price and value don't line up?
A financing specialist can tell you which lenders in our network use guide values, which order full appraisals, and how that changes your cash at closing.
What to do if the aircraft appraises low
- Read the report for factual errors. Wrong engine time, a missed overhaul, avionics left off the equipment list, or damage history attached to the wrong serial number. Send the lender documentation (logbook pages, invoices, 337s) and ask for reconsideration. This is the only argument that reliably moves a value.
- Renegotiate with the seller. A lender's independent value is strong evidence. Your purchase agreement should include a financing or appraisal contingency; have an aviation attorney confirm the wording before you sign.
- Bring more cash. If you still want the aircraft at the price, the table above shows exactly how much more. See down payment strategies.
- Ask about a second appraisal. Some lenders allow one, usually at your cost and with an appraiser they approve.
- Walk away within the contingency. Many buyers find the low appraisal was right.
What doesn't work: arguing from asking prices, or from what the seller paid for the avionics. Appraisers weigh comparable sales and documented condition. To check a value yourself before you offer, use the comp method in how to value a used airplane.
How does an appraiser reach a value?
For piston aircraft, the sales comparison approach does most of the work: the appraiser finds recent sales of the same model, adjusts each for differences in engine time, avionics, condition and history, and reconciles them into one value. Two other approaches show up at the margins. A cost approach (replacement cost less depreciation) can support newer aircraft or unusual modifications with few comparable sales, and an income approach can matter for aircraft on a leaseback or used commercially. A pricing-guide valuation is essentially the sales comparison approach done by the guide's publisher across the fleet rather than for your aircraft.
A formal report typically states:
- The purpose and the value definition used (for example, fair market value or orderly liquidation value), and the effective date
- The aircraft's identity: make, model, serial number, N-number, and engine and prop serial numbers
- Times: total airframe, engine and prop times since overhaul, and the source records reviewed
- Equipment and modifications credited, and any the appraiser declined to credit
- Condition ratings, damage history and how it was treated
- The comparable sales used, their adjustments and the reconciled value
- Limiting conditions, such as records the appraiser did not see
Check the value definition. A lender may ask for a more conservative basis than fair market value, and the label on the number tells you what it means.
How to prepare for an appraisal
Whether you are the buyer (helping the seller prepare) or an owner refinancing, the goal is to make sure the appraiser credits everything that is actually there.
- Organized logbooks with the key pages flagged: first page, latest annual, engine and prop overhaul entries
- A current, dated AD compliance list
- An equipment list with avionics model numbers, plus 337s and STC paperwork for installations
- Invoices for recent major work: overhauls, paint, interior, panel
- A short summary sheet: total time, SMOH, prop time, notable upgrades, any damage history with its repair file
- Squawks fixed and the aircraft clean, especially for an on-site appraisal
- Any confirmed comparable sales you have, with sources

Frequently asked questions
Do all aircraft loans require an appraisal?
No. FLYING Finance notes that below roughly $1 million, many lenders size the loan on a desktop valuation from an industry-standard pricing guide instead of a full appraisal, while reserving the right to order one. A formal appraisal is more likely for unusual, vintage or heavily modified aircraft, damage history, incomplete records, a price well above guide values, or a refinance.
How much does an aircraft appraisal cost?
It depends on the type of valuation. A 2017 AOPA Aviation Finance article put desktop appraisals at about $500 to $600 and physical appraisals at $2,000 to $4,000, with pricing-guide valuations the least expensive. Costs vary with the aircraft, the appraiser and travel, and may have risen since, so get a written quote before you authorize one.
Who pays for the appraisal on an aircraft loan?
The borrower usually pays, either upfront or in closing costs, even though the lender typically orders the appraisal or approves the appraiser so the valuation stays independent. Ask before you commission your own appraisal whether the lender will accept it; many lenders will only rely on reports ordered through them or prepared by appraisers they approve.
How does the appraisal affect my loan amount?
Most lenders calculate loan-to-value on the lower of the purchase price or the appraised value. If the appraisal matches the price, the loan is sized as planned. If it comes in low, the maximum loan shrinks by the lender LTV times the shortfall, and you cover the difference in cash, renegotiate the price or walk away under your contingency.
What can I do if an aircraft appraises low?
Read the report first. If it has factual errors, such as the wrong engine time, missing equipment or a damage history that belongs to another aircraft, send the lender documentation and ask for reconsideration. If the value is sound, use it to renegotiate with the seller, add cash, or exit under your purchase agreement contingency. Some lenders allow a second appraisal.
How long is an aircraft appraisal good for?
There is no single rule. Lenders generally want a recent valuation, and the acceptable age depends on the lender and on how fast the market for that model is moving. If closing slips or you are refinancing an aircraft appraised for an earlier loan, expect the lender to require an update. Ask how old a report it will accept before you order one.
