When to Buy or Sell a Piston Airplane: A Month-by-Month Calendar for Leverage, Inspections and Year-End Tax Timing
This guide is for buyers and sellers deciding when in the year to act. It covers where the leverage tends to sit each season, how to time inspections and ferry flights, and how to back-schedule a December closing for tax purposes.
Is there really a best time of year to buy an airplane?
Seasonality in aircraft sales comes from mechanics, not magic. Knowing the mechanics tells you when they'll help you and when they won't:
- Flying season. In most of the U.S., good weather in spring and summer brings out more shoppers, while winter thins the field. In the South and Southwest the effect is weaker.
- Carrying costs. A seller who doesn't sell by fall pays another winter of hangar, insurance and loan interest, often with an annual coming due.
- The annual cycle. An airplane with a fresh annual is easier to sell. One with an annual due soon invites a buyer to negotiate over the findings.
- Tax year-end. Business buyers want aircraft in service by December 31. That concentrates demand, and it fills shop and escrow calendars.
- Inventory. Sandhills' July 2026 data showed used piston-single inventory down 17.01% year over year, with asking values down just 0.37% (Sandhills). With so few airplanes for sale, good ones sell in any season, and waiting for a "winter deal" can mean missing the airplane.
We don't quote seasonal percentages because we haven't found an auditable source for them. Claims that prices rise or fall by a fixed amount each season should be treated as anecdote.
The buying and selling calendar
| Months | What tends to happen | Buyer move | Seller move |
|---|---|---|---|
| January–February | Fewest shoppers in cold regions; some owners decide over winter to sell or upgrade | Good time to negotiate. Schedule the pre-buy in a hangar, and plan for weather holds on test flights | Do the annual and fix squawks now; gather records and photos |
| March–April | Buyers return; new listings appear | Have your pre-qualification done so you can move on a good listing within days | List now with a fresh annual to meet the spring demand |
| May–July | Peak flying season; the most competition for well-kept airplanes | Expect less room on price; win with speed, clean terms and financing already lined up | Strongest leverage; hold firm on well-documented airplanes |
| August–September | Demand stays steady; business buyers begin year-end planning | Business buyers: start shopping now for a December close | Market to business buyers; sellers who haven't sold start thinking about winter costs |
| October–November | Seasonal demand fades in the North; year-end buyers are active | Personal buyers gain leverage. Business buyers must have a purchase agreement signed by mid-November | Weigh the winter carrying cost against a lower offer now |
| December | Tax-driven closings crowd shops, escrow agents and lenders; holidays shorten the month | Personal buyers: little competition, but slow logistics. Business buyers: close by mid-month | A motivated business buyer may pay for certainty of closing; respond quickly |
Year-end tax timing: back-scheduling a December closing
The 2025 tax law made 100% bonus depreciation permanent for eligible property acquired after January 19, 2025 (IRS). For tax years beginning in 2026, the Section 179 limit is $2,560,000, with the phase-out starting at $4,090,000 (Rev. Proc. 2025-32). Aircraft are listed property, so qualified business use must exceed 50% or bonus depreciation is lost. The date that matters is when the aircraft is placed in service, meaning ready and available for its business use, not just the purchase date.
The size of the stakes explains the December rush. If a $250,000 aircraft qualifies, a first-year deduction at an assumed 32% marginal rate is worth about $80,000 in federal tax this year instead of spread over later years. That's an illustration, not advice; confirm with a CPA. Details are in aircraft tax deductions in the year you buy and aircraft depreciation after the 2025 tax law.
The loan process sets the schedule. Pre-qualification takes 1–3 business days, underwriting 1–2 weeks once there's a purchase agreement, and closing 2–4 weeks from application. Here's a back-schedule for tax year 2026, when December 31 falls on a Thursday:
| By | Milestone |
|---|---|
| Fri, Oct 30 | Pre-qualified; CPA has confirmed the business-use plan and ownership entity (see LLC ownership) |
| Fri, Nov 13 | Purchase agreement signed; deposit with an escrow agent; pre-buy shop booked |
| Mon, Nov 16 – Fri, Dec 4 | Pre-buy inspection, lender underwriting, appraisal if required, lien search. Thanksgiving (Thu, Nov 26) costs a day or two |
| Fri, Dec 11 | Pre-buy findings resolved; insurance bound with the lender as loss payee |
| Fri, Dec 18 | Closing: funds wired, bill of sale and registration application filed with the FAA Registry through escrow |
| Before Thu, Dec 31 | Aircraft delivered and available for business use; first business flight logged. Christmas falls on Fri, Dec 25 |
After closing, the second copy of the registration application gives temporary authority to operate within the U.S. until the certificate arrives. There's no 90-day limit any more, but it isn't valid outside the U.S. See FAA registration.
Negotiation math: what a seller's winter costs are worth
A seller who misses the fall market carries the airplane until spring. The assumptions below are labelled; substitute the seller's real numbers if you can learn them. Only the interest portion of the seller's payment counts as a cost; principal is just moving money from cash into equity.
| Loan interest on a $120,000 balance at an assumed 7.75% | $775/mo |
|---|---|
| Hangar (assumed) | $450/mo |
| Insurance, $1,800/yr (within BWI's 2026 Cessna 172 range) | $150/mo |
| Total carrying cost | $1,375/mo |
| Over 4 winter months | $5,500 |
That total, plus the cost of an annual that will come due before spring, is a rational ceiling on how much a seller should give up to close now. Present it as a reason, not a demand. Sellers without a loan carry less, so expect less room. Insurance figures come from BWI (March 2026), which puts private-owner Cessna 172 premiums at $1,200–$2,500 a year for pilots with 250+ hours.

The buyer's cost of waiting
Waiting for a better season has three costs. The first is rate risk: the Fed raised rates on September 16, 2026, and Prime is now 7.00%. If quotes rise another 0.25 point while you wait, $150,000 over 20 years goes from $1,231 to $1,255 a month, about $5,577 over the full term. The second is availability: inventory is tight, and good airplanes sell in every month. The third is your own flying, the season you spend renting or not flying.
The practical approach is to get pre-qualified early, since it takes 1–3 business days and doesn't commit you. Then shop continuously and move when the right airplane appears. Ask each lender how rate locks work and how long a quote holds between approval and closing. For more on the rate environment, see rate cycles and aircraft values.
Timing inspections, test flights and ferry flights
- Pre-buy vs annual. If the seller's annual is due within a few months, negotiate who pays and whether the pre-buy can be expanded into the annual with the buyer's shop. That's common when the timing lines up. See pre-buy inspection checklist and annual inspection costs.
- Shop calendars. Shops are often busiest in spring, when owners get ready for flying season, and in December with tax-driven pre-buys. Book early in either period.
- Winter weather. Icing and low ceilings can delay test flights and ferry flights by days. Hangar the airplane for the pre-buy so the inspector sees a dry, warm airframe. Winter wind and snow can also hide fluid leaks and corrosion on the ramp.
- Insurance checkout. A new-to-type buyer may need instructor time before the policy covers solo flight. Schedule it with the ferry, not after it.
A seller's calendar
- Late fall to midwinter: do the annual, fix squawks, and organize logbooks, 337s and AD compliance records. Buyers pay for clean records, and their lenders' appraisers check them. See how records affect resale.
- Late winter: price against recent comparable sales and value guides, not last year's asking prices.
- Early spring: list, with the annual date and engine times stated plainly.
- If it hasn't sold by September: decide between a price adjustment now and another winter of carrying costs, using the table above with your own numbers.

Frequently asked questions
What is the best month to buy an airplane?
There is no published, reliable seasonal price index for piston aircraft, so no month guarantees a discount. Buyers in northern regions often have more leverage from late fall through winter, when fewer people are shopping and sellers face another season of hangar and insurance bills. In 2026, tight inventory, down about 17% year over year, weakens that edge. The airplane and its records matter more than the month.
When is the best time to sell an airplane?
List in late winter or early spring so the airplane is on the market, with a fresh annual and complete records, when flying-season buyers start shopping. If you sell to business buyers, fall listings can catch people aiming to close before December 31. Either way, price to recent comparable sales, because buyers' lenders and appraisers will.
Does year-end tax planning affect aircraft prices?
It affects timing more than price. Business buyers who want a first-year deduction need the aircraft acquired and placed in service by December 31. 100% bonus depreciation is permanent for eligible aircraft acquired after January 19, 2025, and qualified business use must exceed 50%. That concentrates demand for inspections, escrow and closings in December. Start by early November, and confirm the tax treatment with a CPA.
How late in December can I close and still take depreciation this year?
The aircraft generally must be placed in service, meaning ready and available for its business use, by December 31, not just purchased. A December 31 closing with the airplane still in another state or awaiting repairs may not qualify. Aim to close by mid-December, leaving time for delivery and a documented first business use, and confirm your facts with a CPA.
Is it cheaper to buy an airplane in winter?
Sometimes, because sellers carry costs through winter. In this guide's example, loan interest, hangar and insurance cost a seller about $1,375 a month, or $5,500 over 4 months. That is a reasonable ceiling for a "winter discount" in negotiation, not a guaranteed markdown. Weather can also delay test flights, the pre-buy and ferry, so build in time.
Should I wait for a better time of year to buy?
Waiting has its own costs. If rates rise 0.25 percentage points while you wait, a $150,000 20-year loan costs $23 more a month, about $5,577 over the full term. In a tight market the right airplane may also sell. Get pre-qualified, shop continuously, and act when a good airplane at a fair price appears.
