Quick reference

Federal Mortgage-Related Laws

  • RESPA Section 8 prohibits giving or receiving anything of value for the referral of settlement service business; routine, unearned referral fees are illegal even if disclosed.

  • RESPA requires a Loan Estimate within 3 business days of application and a Closing Disclosure at least 3 business days before consummation; the consumer must receive the CD before closing.

  • TILA disclosure tolerances: the APR is accurate if within 1/8 of 1% for regular transactions and 1/4 of 1% for irregular transactions; the finance charge tolerance is $100.

  • ECOA (Regulation B) prohibits discrimination based on race, color, religion, national origin, sex, marital status, age, receipt of public assistance income, or good-faith exercise of rights under the Consumer Credit Protection Act.

  • HMDA (Regulation C) requires covered institutions to collect and report data on applications, originations, denials, and pricing; the loan-volume threshold is adjusted periodically by the CFPB.

  • The SAFE Act requires mortgage loan originators to be registered or licensed, pass a written test, complete pre-licensure education, and renew annually with continuing education.

  • HOEPA (Section 32) covers high-cost mortgages using points-and-fees and APR triggers; covered loans face restrictions on prepayment penalties, balloon payments, and late fees.

  • The Fair Housing Act prohibits discrimination in the sale, rental, and financing of dwellings based on race, color, religion, sex, national origin, familial status, or disability.

  • Flood insurance: the Flood Disaster Protection Act requires flood insurance for loans secured by improved real property in a Special Flood Hazard Area, and mandates escrow in many cases.

General Mortgage Knowledge

  • Qualifying ratio guidelines: conventional often uses 28% front-end and 36% back-end; FHA commonly allows 31% front-end and 43% back-end, with compensating factors permitting higher back-end ratios.

  • Maximum conventional conforming loan limits are set annually by FHFA; loans above the limit are non-conforming (jumbo) and generally carry stricter underwriting.

  • LTV = loan amount / lesser of appraised value or purchase price; CLTV includes all liens secured by the property. PMI is generally required above 80% LTV on conventional loans.

  • Amortization: a fully amortizing loan retires principal and interest over the term; an interest-only or balloon loan leaves a balance due at a specified date.

  • Escrow/impound accounts collect 1/12 of annual taxes and insurance monthly; RESPA limits reserves to no more than 1/6 of the annual disbursements for taxes and insurance.

  • Fixed-rate loans lock the rate for the full term; ARMs adjust per an index plus margin, subject to initial, periodic, and lifetime caps.

  • FHA loans require mortgage insurance: an upfront premium plus an annual premium; MIP generally lasts the life of the loan when the LTV at origination exceeds 90%.

  • VA loans typically require no down payment and no monthly PMI, but charge a one-time funding fee that varies by down payment and prior use.

Mortgage Loan Origination Activities

  • Application intake: collect the six pieces of information (borrower name, income, SSN, property address, estimated value, loan amount) that trigger RESPA/TILA disclosure obligations.

  • The Loan Estimate must be delivered or placed in the mail within 3 business days of receiving an application; a revised LE requires a valid changed circumstance.

  • Ability-to-Repay/Qualified Mortgage: verify income, assets, employment, credit, and debts; the general QM uses a 43% DTI benchmark (or price-based thresholds under the revised rule).

  • Complete a good-faith evaluation of the borrower's repayment ability and document the basis for approval or denial; provide adverse action notice within 30 days of a completed application.

  • Order the appraisal and title work after disclosures; the borrower must receive a copy of the appraisal no later than 3 business days before closing.

  • Verify self-employment income with tax returns, profit-and-loss statements, and business licenses; use a written verification of employment for salaried borrowers.

  • Closing: the Closing Disclosure must be received by the borrower at least 3 business days before consummation; a changed CD may require a new 3-day waiting period.

  • Rate lock: confirm the lock date, expiration, and any extension fees; a lock that expires before closing may change the disclosed APR and require a revised LE.

Ethics

  • Fiduciary duty to the borrower includes loyalty, disclosure of conflicts, confidentiality, and acting in the borrower's best interest rather than maximizing commission.

  • Fraud indicators: altered documents, inflated appraisals, undisclosed debts, straw buyers, and occupancy misrepresentation must be escalated, not ignored.

  • Kickbacks and unearned fees violate RESPA and state law; referral arrangements must be disclosed and must reflect bona fide services actually performed.

  • Fair lending: steering borrowers to higher-cost products based on protected characteristics is prohibited; pricing exceptions must be documented and consistently applied.

  • Confidentiality: nonpublic personal information is protected under GLBA; sharing borrower data requires notice, consent, and a permissible purpose.

  • Conflicts of interest: disclose any ownership interest in a title company, appraisal firm, or real estate brokerage; recusal may be required.

  • Advertising: license numbers and required disclosures must appear on solicitations; avoid misleading claims about rates, approvals, or government affiliation.

  • Recordkeeping: retain loan files and disclosure evidence for the required period; accurate, contemporaneous documentation supports both compliance and ethics.
