The Underwriting Pillars
Underwriting balances borrower strength, collateral quality, and structure. Packaging your file against these pillars improves approval odds and pricing. If you’re a first‑time buyer, start with our first‑time financing guide and use the calculator to set a realistic budget.
1) Credit Profile
- FICO and history: Many programs target 700+; exceptions exist with compensating factors.
- Debt metrics: DTI/DSCR and fixed‑charge coverage. Stable, predictable income is valued.
- Public records: Bankruptcies, liens, judgments need clear explanation.
2) Liquidity and Reserves
- Cash & equivalents: Post‑close reserves to cover 6–12 months of payments are common requests.
- Down payment: See down payment norms. 10–25% is typical depending on type and age.
- Other assets/LOCs: Backup liquidity supports risk considerations.
3) Income Quality
- W‑2 vs K‑1/Schedule C/E: Document stability; lenders normalize add‑backs conservatively.
- Business use: If under an entity, lenders may request business financials and tax returns.
- Part 91 vs 135: Charter income adds complexity; some lenders restrict Part 135 usage.
4) Collateral and LTV
- Type, age, time: Newer and liquid models (SR22, TBM, PC‑12, CJ series) are favored.
- Maintenance status: Engine/prop times, logbook completeness, damage history.
- Appraisal/valuation: Lenders may reference Vref/Bluebook, comps, or independent appraisal.
5) Structure
- Term & amortization: Longer amortization lowers payment but increases total interest. See terms & amortization.
- Balloon: Lowers payments with a lump sum at maturity; review balloon pros/cons.
- Rate type: Fixed vs variable affects payment certainty; see rate comparison.
Documentation Checklist
- Two years personal returns (and business returns if applicable); YTD financials.
- Personal financial statement; liquidity proof (bank/brokerage statements).
- Purchase agreement/LOI; aircraft specs; logs summary; recent photos.
- Insurance quote/binder; pilot resume and hours; training/endorsements.
- Entity docs (LLC/Trust), operating agreements, and resolutions if relevant.
Timeline and Process Milestones
- Initial screening: Budget with the calculator; align down payment and LTV.
- Term sheet: Provide financials and aircraft details; get conditional offer.
- Diligence: Appraisal/title/escrow and insurance quoting; pilot training plan.
- Approval: Finalize covenants, prepayment terms, and usage restrictions.
- Closing: Execute docs, fund, record liens, update registration.
Red Flags and How to Mitigate
- Limited liquidity: Increase down payment or reduce purchase price; consider more liquid airframes.
- High‑time engines/overdue maintenance: Address items pre‑close or escrow holdbacks.
- Spotty documentation: Organize logs and titles; engage reputable escrow/title services.
Self‑Assessment Rubric
Score yourself 1–5 on each line; 4s and 5s suggest stronger approval/pricing odds.
- Credit depth: 1=thin history, 5=long spotless history.
- Liquidity: 1=just enough down, 5=12+ months of payments in reserve.
- Income stability: 1=volatile/self‑employed without trend, 5=stable multi‑year with cushion.
- Collateral liquidity: 1=thin market, 5=broad/active market (e.g., PC‑12/TBM/CJ).
- Documentation readiness: 1=fragmented, 5=organized binder ready day one.
How to Improve Approval Odds
- Right‑size the ask to your liquidity and income; align payment with budget using the calculator.
- Reduce LTV with a slightly larger down payment or trade‑in.
- Choose popular, liquid models in good maintenance standing.
- Demonstrate a plan for training, insurance qualifications, and hangar arrangements.
- Provide complete, organized documentation up front to avoid back‑and‑forth.
Special Situations
- Older aircraft/high‑time engines: Expect lower LTV caps and tighter terms. Engine reserve plans help.
- International buyers or trusts: Registration/Trust structures add steps; see FAA registry resources.
- Experimental/amateur‑built: Program availability varies; documentation and safety record matter.
FAQs
What FICO do I need for an aircraft loan?
Many programs prefer 700+, but compensating factors (lower LTV, strong liquidity) can offset. Approval is multi‑factor.
How much should I budget for reserves?
6–12 months of payments plus set‑asides for insurance, hangar, and maintenance is a common anchor, but policies vary by lender.
Will occasional Part 135 charter hurt my approval?
Some lenders prohibit or limit. If permitted, expect tighter underwriting and documentation of operations and insurance.
