Skip to main contentThe Glossary is a reference for important mortgage industry terms and concepts used across the Pylon platform and in this documentation. Entries explain what each term means, how it is calculated or applied, and how it shows up in the API or in the loan process.
Use the navigation to browse entries or search for a specific term. The glossary is updated over time as we add new concepts and refine existing ones, so check back for additional entries.
What you’ll find in each entry
Entries typically include:
- A clear definition of the term or concept
- How it is calculated or determined (where relevant)
- How it is used in mortgage origination, pricing, or compliance
- How it appears in the Pylon API or in related guides
Not every entry follows the same structure; each is written to fit the concept.
