According to Jahid Fazal-Karim, owner and chairman of the board of Jetcraft, the sweet spot for buying a plane is between three and five years old in terms of value.

He is often referred to as one of the most powerful players in business and private aviation. Jetcraft
由於商務噴射機的價格昂貴，分數擁有權（Fractional Ownership）是指有意購買商務噴射機的買主，不需購整架商務噴射機。透過如Netjets或是Flex Jet專門進行分數擁有權的商務噴射機公司，買主可以購買1/4、1/8或其它比例的商務機擁有權，而由商務噴射機公司來進行操作-包括飛行及維修。參加分數擁有權計劃的顧客，每個月可有固定時數的飛行。由於操作分數擁有權的商務噴射機公司，擁有許多飛機，因此顧客雖然擁有某架飛機的擁有權，但並不一定搭乘擁有的飛機。因此參加分數擁有權的計劃，顧客是以分擔商務噴射機公司購機和操作成本，以較低廉的價格，來享受商務噴射機飛行服務，但是就因為每個買主只擁有"部分所有權"而且並非天天都需要用到飛機，所以需要飛行得事先預約，再由商務噴射機公司安排飛機和空勤組員。
For the decade starting in 2017, Aviation Week predicts 11,346 deliveries of business aircraft (jets or not) valued at $250.1 billion, with a fleet growing from 31,864 aircraft to 36,702 aircraft (64% in North America): 4,838 more at an average annual growth rate of 1.6%, with 5,835 retirements. For the coming five-year period, Textron Aviation should lead the market with a 22.8% market share, followed by Bombardier with 20.4%, Embraer with 16.6%, Gulfstream with 15%, Dassault with 8.4% then the rest of manufacturers with 16.9%. There should be 22,190 Engine deliveries, led by the Honeywell HTF7000, Williams FJ44, Pratt & Whitney Canada PT6A Medium, Pratt & Whitney Canada PW300 and the Pratt & Whitney Canada PT6A Large. The average utilization should be 365 flight hours per aircraft per year.
The 91,000 lb (41,000 kg), 6,750 nmi Gulfstream G550 was selected for the IAI EL/W-2085 Conformal Airborne Early Warning AESA radar for Italy, Singapore and Israel (which also has IAI Sigint G550s) while L3 Technologies transfers the U.S. Compass Call electronic-attack system to the G550 CAEW-based EC-37B, like the NC-37B range-support aircraft, and will modify others for Australia’s AISREW program, Northrop Grumman proposes the G550 for the J-Stars Recap;
Prospective aircraft buyers often look for jets for sale by searching Google, gathering information on various makes & models and their performance characteristics, and on condition, age, price and other information about specific jets for sale. Most private airplane buyers use standard phrases like: "airplanes for sale", "private jets on sale" or "airplanes on market" for their search.
Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
