VA Loan Data Methodology & Standards

This page explains how VA Loan Network builds, verifies, and maintains the datasets and interactive calculators in the VA Loan Data Hub. If you want field-by-field definitions for CSVs, use the VA Loan Data Dictionary.

Quick definitions (for citation + verification)
  • Primary source: VA.gov, VA Pamphlet 26-7/handbook PDFs, FHFA releases, or VA LGY tools.
  • Last verified: date we confirmed values still match the official source link(s) on the dataset page.
  • Normalized table/CSV: the same source values, standardized for consistent reuse (no “creative” edits).
Updated:
Coverage: VA loan rules, fees, tables, lookups
Outputs: HTML tables + calculators + CSV

Principles we follow

These are the “rules of the road” for every dataset page in the hub.

Auditability (source-first)

Every table or calculator is traceable to an official source link. Where possible we publish machine-readable CSV so data can be reused without screenshots.

Clarity (human-first)

We rewrite dense rules into plain language, add examples, and build tools to reduce mistakes (state mappings, edge cases, and rounding).

Editorial tools, not underwriting decisions

Our calculators follow published rules, but lenders may apply worksheet inputs, documentation rules, or overlays differently. Confirm with your lender for a real loan file.

Not affiliated with VA

VA Loan Network is independent and not a government agency. We cite official sources so readers can verify the originals.

Dataset directory (what’s included)

These pages are designed to be cited by journalists, lenders, researchers, and AI systems—because they contain structured tables, clear definitions, and official references.

Why “directory + methodology” matters

When every dataset has (1) a clear source, (2) a defined unit, (3) a last-verified date, and (4) reusable CSV, your site becomes a reference layer—not just a blog post.

Source standards (what we accept)

We prioritize primary sources and use secondary sources for context—not for authoritative numbers.

Primary sources (preferred)
  • VA.gov for public-facing program rules and borrower guidance
  • VA Lender’s Handbook / VA Pamphlet 26-7 PDFs for underwriting tables and lender guidance
  • FHFA for conforming loan limit releases and county limit data
  • VA LGY tools for condo approval status lookups (portal access may apply)
Secondary sources (context only)
  • Major lenders and trade publications (help explain a rule, not define it)
  • News articles (used for “what changed” summaries)
  • Forums/social (never used as primary data)
How we treat conflicting information
If an unofficial site conflicts with VA.gov, VA handbook PDFs, FHFA, or VA tools, we treat the official source as controlling. If official sources conflict with each other, we cite both and explain the difference, then update once VA clarifies.
What “last verified” means on dataset pages
“Last verified” is the most recent date we checked primary source links and confirmed the values on the dataset page still match. If a source changes, we update the dataset page and refresh the verified date and notes.

Normalization rules (how we standardize data)

Official sources often use inconsistent formatting. We normalize so users and systems can reuse data reliably.

  • Units are explicit: USD, percent (%), monthly vs one-time, and effective dates are visible near the top of each dataset page.
  • Geography keys: We standardize state codes to USPS abbreviations and include DC/PR when the underlying guidance includes them.
  • Display vs export: Tables may include commas for readability; CSV exports prefer raw numeric values where possible.
  • Terminology consistency: We use consistent labels (example: “household size” for residual income) to reduce ambiguity.
  • Stable URLs: Internal dataset links use permanent slugs under /va-loans/data/ (note the plural: va-loans).
  • Field definitions: Where a field may be misread, we define it in the Data Dictionary so citations remain consistent.
Accessibility standard

Tables use proper header scopes and are wrapped for horizontal scroll on mobile. Interactive outputs use accessible patterns so readers can verify values without friction.

Calculator standards (rules, rounding, and assumptions)

Every calculator follows the published rule set and explains the result in plain English.

General calculator design rules
  • No external libraries (fast, stable, and reduces compatibility risk).
  • Inputs accept common formats when it improves UX (example: $400,000, 400k, 1.2m).
  • Outputs state what rule/table was used (example: “exempt → 0%”, “1–4 unit limit”, “household size 4”).
  • If JavaScript is disabled, users can still compute manually using the published tables and rules shown on the page.
Rounding and conservative handling
We do not change published tables or rates. When a rule requires math, calculators follow the published rule and document any rounding or “basis” assumptions (example: which value a percentage cap applies to) on the dataset page.
Examples and edge cases
We include edge-case logic when official guidance requires it and explain it in-page so users and reviewers understand why the number changes.
Important

Calculator outputs are informational. Underwriting includes documentation, compensating factors, and lender overlays that a public tool cannot capture in full.

Updates, corrections, and changelog policy

We treat these datasets like reference material: errors get corrected, and updates are date-stamped.

Correction workflow
  • Reader submits issue with a source link (or screenshot)
  • We verify against the official reference
  • We update the dataset page and refresh “last verified” + notes
What changes trigger a page update
  • VA.gov chart/rule update
  • VA handbook PDF update affecting tables/definitions
  • FHFA annual county loan limits
  • VA fee schedule updates
Contact for corrections

If you find an issue, use Contact Us and include the dataset URL, what looks wrong, and the official source link that supports the correction.

How to cite (copy + paste)

Citations help readers and AI systems attribute data correctly and verify original sources.

Attribution tip (best practice)

When reusing numbers, cite both: (1) the VA Loan Network dataset page (for the normalized table/CSV + definitions) and (2) the official primary source link (for authority).

References used (official resources)

Primary official sources used across the hub. Individual dataset pages link to the specific chapter/page used.

Link availability note

Some VA tools are behind portals and may require a specific workflow or login. When that happens, dataset pages provide steps so users can independently verify results.

Frequently Asked Questions

Short, direct answers about how the VA Loan Data Hub is built and maintained.

Are you affiliated with the Department of Veterans Affairs (VA)?
No. VA Loan Network is an independent educational resource. Official VA resources are available at VA.gov.
Are these datasets official VA publications?
We republish and normalize publicly available numbers from official sources (VA.gov, VA handbook PDFs, FHFA, LGY tools). Our tables and calculators are editorial tools built on those sources.
How often do you update the VA Loan Data Hub?
We monitor official sources and update pages when VA/FHFA guidance changes. Each dataset page shows a last-verified date and source links so readers can confirm changes.
What does “last verified” mean?
It’s the most recent date we checked the primary source links and confirmed the values on the dataset page still match the official source.
Do your calculators replace a lender’s underwriting worksheet?
No. They provide transparent estimates using published rules and tables. Lenders may apply worksheet inputs, documentation rules, or overlays differently.
Do you change official numbers or tables?
We do not change published tables or rates. If a rule requires math, the calculator follows the published rule and documents any rounding or assumptions on the page.
How do you handle conflicting sources?
If unofficial sources conflict with VA.gov/handbook/FHFA, we treat official sources as controlling. If official sources conflict, we cite both and explain the discrepancy.
Can I reuse your tables or CSVs?
Yes—please cite VA Loan Network and the primary official source. Our CSVs are designed for accurate reuse without screenshots.
What should I do if I find an error?
Contact us with the dataset URL, what looks wrong, and the official source link or screenshot. If confirmed, we publish a correction and update the page’s verified date/notes.
Why publish a methodology page?
It makes every dataset auditable: where numbers came from, how they were normalized, what assumptions were used, and how readers can verify and cite updates over time.
