## Compare Providers on Capability, Scope and Execution 

Collateral Finance mandates require valuation work that matches the purpose of the assignment. Current market value, orderly liquidation value, future base value, maintenance-adjusted value and lease-encumbered analysis answer different questions and should not be substituted casually. 

This ranking is intended to help professional aviation buyers build a shortlist. The order reflects service relevance and publicly described capability rather than a claim that one company is universally superior for every mandate.

Editorial Methodology

Match the Provider to the Mandate

We compare specialization, service depth, transaction fit and execution capability. Buyers should still complete legal, technical, regulatory, insurance and commercial due diligence before appointment.

Selection Criteria

## What to Compare Before Signing

- valuation purpose and standard
- appraiser credentials
- maintenance adjustment methodology
- market transaction data
- reporting accepted by the intended user

Request a written scope that defines deliverables, exclusions, third-party costs, pricing, liability allocation, termination rights and the people responsible for delivery. Where the service touches operational control, maintenance, finance, insurance or regulatory approvals, confirm those responsibilities explicitly before commercial commitment. 

Procurement Note

Normalize the Scope Before Comparing Fees

Two aviation proposals can quote different work under the same service label. Compare them on identical assumptions before ranking price, and identify every dependency that remains with the client or a third party. 

Frequently Asked Questions

## Provider Selection FAQ

How were the providers in this top 10 selected?

This is an editorial comparison based on public service scope, aviation specialization, relevance to the stated buyer segment and fit for professional procurement. It is not a safety certification, credit rating or substitute for vendor due diligence.

What should a buyer compare before appointing a aircraft valuation firm?

Compare the contracting entity, precise scope, approvals where relevant, service exclusions, pricing, third-party costs, insurance, references, liability allocation and the escalation path for operational or transaction problems.

Should the lowest fee win the mandate?

The fee should be normalized against the same scope. A lower headline price can shift technical work, third-party costs, downtime, regulatory responsibility or execution risk back to the client.

How many providers should be approached?

For a material aviation mandate, a controlled shortlist of three to five qualified providers is usually enough to create a meaningful comparison without turning the process into an unstructured market blast.
