Founded by Stefan Duller in 2010, the firm grew out of a banking career — and that discipline still shapes how we work: rigorous analysis, careful structuring and absolute discretion on every mandate. We acquire, sell and finance business jets for a worldwide clientele, drawing on an extensive network of operators, OEMs and brokers. As a member of the EBAA, we operate to the standards of the European business aviation community — and as a boutique, we give every transaction the senior attention it deserves. Every mandate is led personally and handled with complete discretion. There are no junior handoffs and no conflicting house positions to work around — just senior attention on the details that move a transaction forward. From the first valuation to final delivery, we sit on one side of the table — yours. - Founded: 2010 - Headquarters: Vienna, Austria - Service area: Worldwide - EBAA member ## Services ### Aircraft Sales [View Aircraft Sales](https://avionmar.com/services/sales) When the time comes to sell, presentation and discretion decide the outcome. We position your aircraft to the right buyers, worldwide. Selling a business jet is a confidential, detail-driven exercise. We keep you current with up-to-date market intelligence on any aircraft — hours, price, days on market and key specifications — and reach buyers through a broker network where many off-market aircraft trade discreetly, often at attractive pricing. From a defensible valuation and a considered marketing strategy to qualifying buyers, steering negotiations and closing cleanly, AVIONMAR manages the entire process on your behalf. You retain control; we carry the work. **Process:** - **01 Valuation & Positioning:** We establish a realistic, defensible market value and a positioning strategy grounded in current transaction data and the aircraft's true condition. - **02 Marketing & Network:** Your aircraft is presented discreetly through our global broker network and qualified channels — never mass-listed or exposed. - **03 Qualifying Buyers:** We vet every enquiry and engage only credible, capable buyers, protecting both your time and your confidentiality. - **04 Negotiation:** We lead price and contract negotiations on your behalf, balancing momentum with the strongest commercial terms. - **05 Pre-Buy & Inspection:** We coordinate the technical inspection and records review, managing findings so the transaction stays on course. - **06 Closing & Handover:** We oversee escrow, documentation, de-registration and delivery for a clean, on-time transfer of title. ### Aircraft Acquisition [View Aircraft Acquisition](https://avionmar.com/services/acquisition) The right aircraft is rarely the one on the open market. We find it, evaluate it, and secure it on your terms. Acquisition is where preparation meets access. We translate your mission into a precise brief, surface off-market opportunities through two decades of relationships, and guide you through inspection, negotiation and closing — so you buy the right aircraft at the right price, without surprises. **Process:** - **01 Mandate & Brief:** We define your mission profile, budget and timeline, translating how you actually fly into a precise acquisition brief. - **02 Off-Market Research:** We canvass our global network to uncover aircraft that are available but never publicly listed. - **03 Shortlist & Review:** We present a curated shortlist with candid analysis of condition, history and value — not a sales pitch. - **04 Offer & Negotiation:** We structure the offer and lead negotiations, protecting your position on both price and terms. - **05 Pre-Buy Inspection:** We manage the pre-buy inspection and records audit, ensuring findings are resolved before you commit. - **06 Closing & Registration:** We coordinate escrow, documentation, registration and delivery through to a smooth handover. ### Aircraft Financing [View Aircraft Financing](https://avionmar.com/services/financing) Structure matters as much as rate. We arrange lease and loan solutions tailored to your transaction and your balance sheet. Whether you need financial leasing, a loan or a wet or dry lease for your aircraft, we can provide the right financing. With more than 20 years of experience in aircraft financing and a background in banking, our team has established very close relations with international banks, aircraft leasing companies and operators. AVIONMAR can provide you with a selection of different aircraft in various categories available for dry or wet lease. Share your specific requirements, the aircraft type you are looking for and your mission profile — and we will provide the perfect aircraft for your utilization. **Process:** - **01 Needs Analysis:** We assess your objectives, tax position and ownership structure to define the right financing approach. - **02 Structuring:** We design a lease or loan structure aligned to the asset, jurisdiction and your balance-sheet goals. - **03 Lender Network:** We approach the specialist banks and lessors best suited to your profile, inviting competitive terms. - **04 Terms & Approval:** We negotiate rate, tenor and covenants, and manage the credit process through to approval. - **05 Documentation:** We coordinate facility agreements, security and registration alongside your legal advisors. - **06 Drawdown:** We align funding with closing so capital is in place exactly when the transaction completes. ## Aircraft Inventory ### Bombardier Challenger 300 [View listing](https://avionmar.com/inventory/challenger-300-sn-20274) - Year: 2010 - Serial Number: SN 20274 - Status: available - Price: $12,750,000 - Total Time: 5557 hrs - Landings: 4983 - Passengers: 8 - Engines: Honeywell HTF7000 (on MSP Gold) - Avionics: Rockwell Collins ProLine Advance; FANS 1/A, CPDLC, ADS-B Out - Location: Austria (EASA certified) A proven super-midsize business jet with outstanding range and cabin comfort, meticulously maintained with full pedigree documentation. **Highlights:** - Just returned from its 192-month inspection — ready to fly - Technically as well as cosmetically in excellent condition - ProLine Advance avionics; FANS 1/A, CPDLC and ADS-B Out - Cabin partially refurbished in 2021 with new Taiping carpet - Engines and APU on Honeywell MSP Gold - Aircraft based in Austria – EASA certified **Interior:** This Challenger 300 offers an eight-seat configuration with unmatched comfort.

AVIONMAR advises clients on aircraft acquisition, sales and financing. We support the full transaction lifecycle, from market positioning and sourcing to negotiation, pre-buy, closing and handover. ### Do you only work with publicly listed aircraft? No. A significant part of our work is off-market sourcing through our broker and operator network. This often improves confidentiality and can open opportunities not visible in public listings. ### Where is AVIONMAR based? AVIONMAR is headquartered in Vienna, Austria, with a second office in Pörtschach. We were founded in 2010 and are a member of the European Business Aviation Association (EBAA). While we are based in Austria, we source and transact business aircraft for clients worldwide. ### What types of aircraft does AVIONMAR broker? We focus on business aviation — business jets and helicopters across the light, midsize and large-cabin segments. Whether you are acquiring a single private jet or repositioning a fleet asset, we source candidates worldwide and assess each one against your mission profile and budget. ### How long does an aircraft sale usually take? It depends on aircraft type, condition, maintenance status and current demand. Typical timelines range from a few weeks to several months. We provide realistic timing guidance based on current market evidence. ### Can you help if I am buying my first aircraft? Yes. We guide first-time buyers through mission definition, shortlist creation, technical and records review, negotiation structure, and closing logistics so decisions are made with full clarity. ### Do you arrange financing as well? Yes. We work with specialist lenders and leasing partners to structure loan or lease solutions aligned with your ownership model, jurisdiction and transaction profile. ### What is the difference between an aircraft loan and a lease? With a loan you finance the purchase and own the aircraft, building equity while repaying principal and interest. With a lease you pay to operate an aircraft owned by the lessor, usually with lower upfront capital and defined end-of-term options. The right structure depends on your tax position, usage and ownership horizon. ### How is an aircraft's market value determined? Value reflects make and model, year, total time and cycles, maintenance and inspection status, engine program enrollment, avionics, interior and exterior condition, damage history and current supply and demand. We benchmark each aircraft against comparable transactions so pricing is grounded in current market evidence rather than asking prices alone. ### How is AVIONMAR compensated? Our compensation is agreed transparently at the outset of each mandate, before any work begins. Because we represent only one side of a transaction, our incentives stay aligned with yours — there are no conflicting house positions or hidden inventory to work around. ### What information do you need to start a search mandate? We usually begin with mission profile, preferred aircraft category, passenger and range requirements, budget framework, timeline, and any registration or operational constraints. ### Can AVIONMAR help with pre-buy inspections and closing? Yes. We coordinate pre-buy inspections, records checks, negotiation of findings, escrow and documentation workflows so the transaction moves from offer to delivery with fewer surprises. ### Does AVIONMAR publish market data or reports? Yes. We publish concise market reports on selected business aircraft types, summarizing listing activity and pricing context to support acquisition and sales decisions. You can browse the latest editions on our Market Reports page, or request a report focused on a specific target aircraft. ### How do I get in touch? Use the contact form or call us directly. We can also discuss your requirements via a confidential introductory call before any formal mandate is agreed. ## Team ### Stefan Duller - Role: CEO - Department: Direction ### Nicole Duller - Role: Head of Marketing & Finance - Department: Marketing & Finance ### Markus Bancalari - Role: Sales Director - Department: Sales ### Anna Widowitz-Stern - Role: Head of Administration and Sales Support - Department: Administration ### Stefan Hösle - Role: Legal Counsel - Department: Legal ### Ziyun Zhong - Role: Administration and Sales Support - Department: Administration ## Contact - Email: office@avionmar.com - Phone: +43 4272 44 7 66 - Website: https://avionmar.com - **Vienna — Headquarters:** Hegelgasse 8/14, 1010 Vienna, Austria (Vienna, Austria) - **Pörtschach — Backoffice:** Klagenfurter Straße 79, 9210 Pörtschach, Austria (Pörtschach, Austria) ## Legal - [Privacy Policy](https://avionmar.com/privacy-policy) - [Imprint](https://avionmar.com/imprint)
