How to price a Beechcraft Bonanza for sale

Two Bonanzas with the same model year and the same total time can be $100,000 apart in what they actually sell for, and both prices can be right. Pricing a Bonanza is less about the year on the data plate than about six things the market pays for, and the discipline is weighing them against real comparable sales rather than against what the owner hopes.

I fly a Bonanza, I’ve bought one, and I price them for sellers. Here is how the number gets built.

Start with the model, not the year

“Bonanza” covers seventy-plus years of production and several distinct airplanes. The V-tail 35 series, the straight-tail 33 series (Debonair and F33A), and the six-seat 36 series (A36, B36TC, G36) each have their own market, their own buyers and their own price curve. An F33A and an A36 of the same year are not comparables for each other, and a V-tail is its own conversation entirely.

Within a series, the production changes that matter to buyers are the ones that changed the airplane: engine (IO-470 to IO-520 to IO-550), gross weight increases, the switch to the 28-volt electrical system, and later the factory glass panel. Know which side of each change the aircraft sits on before you look at a single listing.

The six things buyers pay for

1. Engine time and history. Hours since major overhaul, who did the overhaul, and whether it was a factory reman, a field overhaul from a known shop, or an unknown. An engine near TBO is priced as an engine about to be replaced, which on a Bonanza is a significant fraction of the airplane’s value. A recent top overhaul is not a major overhaul and buyers know the difference.
2. Avionics. This is where Bonanza values have moved the most in the last decade. A WAAS GPS navigator, ADS-B Out, a modern autopilot and a glass primary display add real money; an upgraded panel can return much of its cost at sale, while an original panel with a single old GPS is priced as a panel the buyer will replace. Be specific in the listing: model numbers, not “nice avionics.”
3. Damage history. A documented, well-repaired gear-up from decades ago is a discount, not a dealbreaker. An undocumented repair, a missing 337, or a wrinkle nobody can explain is a much larger discount, because the buyer is pricing uncertainty. Disclose everything, with paperwork, and the discount stays small.
4. Logbooks and compliance. Complete logs from new, a current AD compliance list, and the recurring Bonanza items signed off on schedule. Missing logbooks take a meaningful percentage off the value of any aircraft, and on an older Bonanza they can take the airplane off some buyers’ lists entirely. (See How to read aircraft logbooks before you buy.)
5. Corrosion and where it lived. A hangared airplane from a dry climate is priced differently from one tied down on the coast, and buyers’ pre-buy shops will check. Wing bolts, the spar carry-through and the tail are where a Bonanza shows its history.
6. Paint, interior and the cosmetic layer. Real, but last. Fresh paint and a new interior make the airplane sell faster more than they make it sell higher. Don’t repaint to sell; do clean, detail and photograph it like you mean it.

Then find the comparables

The published guides (Vref, the Aircraft Bluebook) are the starting point, and they are what the buyer’s lender will look at. They are not the market. The market is what similar airplanes actually sold for in the last several months, and asking prices on the listing sites are not that either; an airplane that has sat at a price for 200 days is telling you the price is wrong.

A broker’s edge here is the sold data: what the comparable Bonanzas closed at, how long they sat, and what came off the price after the pre-buy. That is the number you defend in a negotiation.

Price to sell, not to anchor

An overpriced airplane doesn’t sell slowly; it doesn’t sell. Serious buyers and their brokers see the whole market and skip the outliers. The airplane then sits, the listing goes stale, and when the price finally drops, buyers wonder what the pre-buy found. Price it where the comparables say it belongs, build a package that proves the condition, and the right buyer arrives quickly.

What this looks like in practice

Listing representation starts with exactly this exercise: a written valuation against real comparables, with the six factors above scored for your aircraft, before we talk about photography or listings. If you own a Bonanza and want to know what it is actually worth right now, tell me about it and I’ll give you a straight answer.
