Regulation Z, for the NMLS exam

Compiled by the Sitonce editorial team from the NMLS Resource Center and the federal regulations named belowUpdated 3 min readFacts verified 4 September 2026
The short answer

Regulation Z implements the Truth in Lending Act at 12 CFR 1026. It carries TRID, the right of rescission, ability to repay and qualified mortgages, HOEPA high-cost rules, originator compensation and advertising rules.

If you learn one regulation properly, learn this one. More of the exam comes out of Regulation Z than any other single source.

The Truth in Lending Act dates from 1968. Regulation Z implements it, and successive rules have loaded a great deal onto that frame.

What sits inside it

  • The finance charge and the annual percentage rate
  • TRID - the Loan Estimate and Closing Disclosure
  • The right of rescission
  • Ability to repay and qualified mortgages
  • HOEPA high-cost mortgages
  • Loan originator compensation and qualification
  • Advertising rules and trigger terms
  • Appraisal independence

Finance charge and APR

The finance charge is the cost of credit as a dollar amount. The APR expresses that cost as a yearly rate, and it is higher than the note rate because it folds in the finance charges.

The APR is treated as accurate within 0.125 percent on a regular transaction, and 0.25 percent on an irregular one.

Ability to repay

A creditor must make a reasonable, good-faith determination that the consumer can repay, considering eight underwriting factors at 12 CFR 1026.43(c)(2).

A qualified mortgage carries a presumption of compliance. Points and fees are capped at 3 percent of the total loan amount for a loan of 100,000 dollars or more.

The 43 percent figure moved

A 43 percent debt-to-income limit defined the General QM until a price-based standard replaced it in 2021. Older prep material still presents 43 percent as current. Know what it was and know it changed.

HOEPA

A high-cost mortgage triggers additional protections. The APR triggers are 6.5 percentage points over the average prime offer rate for a first lien of 50,000 dollars or more, and 8.5 points for a subordinate lien.

Homeownership counseling is required before a high-cost mortgage is made.

Originator compensation

Compensation may not vary with a term of the transaction, under 12 CFR 1026.36(d)(1). An originator paid by the consumer may not also be paid by anyone else, under 12 CFR 1026.36(d)(2).

Those two rules between them close the door on the arrangements that made yield spread premiums controversial.
