Sample Query

Average FICO/LTV and 60+ day delinquency UPB by vintage, Fannie Mae purchase loans.

SELECT orig_vintage_year, AVG(fico_score) AS avg_fico, AVG(orig_ltv_ratio) AS avg_ltv, SUM(CASE WHEN dq_status >= 60 THEN upb_at_issuance END) AS dq60_upb
FROM loan_performance_all
WHERE agency = 'FNMA' AND orig_purpose = 'Purchase' AND orig_vintage_year BETWEEN 2020 AND 2023 GROUP BY 1 ORDER BY 1;

Why TrueABS vs. Legacy Platforms

ICE/eMBS and Black Knight/McDash charge $50K–$200K/yr for access built on the same free public Fannie Mae disclosures we use. Their moat is legacy lock-in, not the data. TrueABS reconstructs the full format history (a Format Registry, not ad-hoc ETL patches) so vintage data stays consistent — at developer-first pricing.
