RESPA — Real Estate Settlement Procedures Act
Regulation X · 12 U.S.C. § 2601–2617
- Special information booklet: review §1024.6 delivery and coverage exceptions; do not confuse statutory section numbering with Regulation X sections.
- Loan Estimate versus GFE: TRID-covered transactions use Regulation Z disclosures; not every mortgage uses the same disclosure regime.
- Servicing requests: distinguish notices of error and requests for information, acknowledgement/response duties and exceptions; one universal deadline is insufficient.
- Section 8: Prohibits kickbacks, fee-splitting, and unearned fees for settlement services
- Section 9: Seller cannot require buyer to purchase title insurance from a specific company
- Section 10: Limits escrow account deposits to 2 months of cushion beyond annual obligations
- Affiliated Business Arrangement: Must disclose, borrower can choose alternative, no required use
- Marketing Service Agreement (MSA): Must provide actual services; cannot be a disguised referral fee
TILA — Truth in Lending Act
Regulation Z · 15 U.S.C. § 1601–1667f
- Regulation Z implements TILA — applies to consumer credit transactions
- Loan Estimate must be provided within 3 business days of application (6 data points trigger)
- Closing Disclosure must be provided at least 3 business days before consummation
- Rescission under §1026.23: generally three business days after the latest required event for covered principal-dwelling transactions; purchase loans and certain same-creditor refinancings are exempt. Check scope and new-advance exceptions.
- APR accuracy: generally 1/8 percentage point; irregular-transaction tolerance and mortgage exceptions are in §1026.22. ARM does not automatically mean irregular.
- Advertising triggers: If specific credit terms are advertised, full disclosures required (Reg Z trigger terms)
- Trigger terms in ads: payment amount, number of payments, finance charge, down payment amount
- HPML and high-cost mortgage are different tests. Check the applicable lien/loan category, APR/APOR criteria, points/fees and current adjusted thresholds rather than one abbreviated threshold.
ECOA — Equal Credit Opportunity Act
Regulation B · 15 U.S.C. § 1691–1691f
Prohibits discrimination in any aspect of a credit transaction based on:
Key: Adverse action notice must be sent within 30 days of application, stating specific reasons for denial (or the right to request reasons).
HMDA — Home Mortgage Disclosure Act
Regulation C · 12 U.S.C. § 2801–2810
- Home Mortgage Disclosure Act — requires reporting of mortgage data to detect discrimination
- Regulation C implements HMDA
- Applies to banks, savings associations, credit unions, and mortgage companies meeting thresholds
- Must report: applications received, loans originated, loans purchased, and applications denied
- Data collected: race, ethnicity, sex, income, loan amount, property location, loan type, action taken
- Loan Application Register (LAR) submitted annually to regulators
- Purpose: detect lending discrimination and ensure community credit needs are met
- Modified LAR available to the public (personal identifiers removed)
Fair Housing Act
42 U.S.C. § 3601–3619
Prohibits discrimination in the sale, rental, and financing of housing based on 7 protected classes:
Tip: Remember "CR RN SFD" — Color, Religion, Race, National origin, Sex, Familial status, Disability. Compare with ECOA which adds marital status, age, and public assistance but does NOT include familial status or disability.
Dodd-Frank / Qualified Mortgage (QM) Rules
Dodd-Frank Wall Street Reform · ATR/QM Rule
- Ability-to-Repay (ATR): Lender must verify borrower can repay the loan (8 underwriting factors)
- ATR factors: income/assets, employment, monthly payment, other loan payments, other obligations, DTI, credit history, and monthly payments on simultaneous loans
- Qualified Mortgage (QM): Provides safe harbor or rebuttable presumption of ATR compliance
- Current General QM under §1026.43(e)(2) uses price-based criteria and other product and underwriting requirements, not a universal 43% DTI ceiling. The creditor must consider and verify income/assets and debts and consider DTI or residual income. Historical 43% and temporary GSE QM shortcuts are not a current blanket approval rule; program and lender criteria remain separate.
- QM features, terms and points/fees depend on the category, exceptions and adjusted loan-size thresholds. Do not apply one flat percentage to every loan.
- The former temporary GSE QM route is historical; do not present it as a current shortcut.
- Small-creditor and balloon-payment QM routes have distinct eligibility, portfolio and other conditions; review current rules and adjusted asset thresholds.
- CFPB (Consumer Financial Protection Bureau): Enforces Dodd-Frank consumer protection provisions
- Loan Originator Compensation: Cannot be based on loan terms or conditions (except loan amount)
SAFE Act — Licensing Requirements
Secure and Fair Enforcement for Mortgage Licensing Act of 2008
- SAFE Act = Secure and Fair Enforcement for Mortgage Licensing Act of 2008
- Requires MLOs to be either state-licensed or federally registered through NMLS
- State-licensed MLO: Works for non-depository institutions (mortgage companies, brokers)
- Federally registered MLO: Works for depository institutions (banks, credit unions)
- Pre-license education: 20 hours minimum (3 federal law + 3 ethics + 2 non-traditional + 12 electives)
- Continuing education: 8 hours annually (3 federal law + 2 ethics + 2 non-traditional + 1 elective)
- Must pass SAFE MLO exam with 75% or higher score
- Criminal background check and credit report required through NMLS
- NMLS identifiers track companies, branches and individuals. Display requirements depend on the document and applicable federal and state rules.
- Minimum licence criteria: §1008.105 distinguishes the seven-year felony condition from fraud, dishonesty, breach-of-trust and money-laundering felonies at any time; exceptions and state requirements need review.
- Renewal and CE: check current NMLS and state deadlines, extra education and late-renewal conditions; no universal 30-day CE grace period is promised.
Key Mortgage Formulas
Must-know calculations for the MLO exam
Loan-to-Value (LTV)
LTV = Loan Amount ÷ Property Value (or Appraised Value)
Example: Home value $400,000, loan $320,000 → LTV = 320,000 ÷ 400,000 = 80%
Combined LTV (CLTV)
CLTV = (1st Mortgage + 2nd Mortgage) ÷ Property Value
Example: $300K first + $50K HELOC on $400K home → CLTV = 350,000 ÷ 400,000 = 87.5%
Front-End DTI
Housing DTI = Monthly Housing Payment (PITI) ÷ Gross Monthly Income
Example: PITI $2,000, income $6,000/mo → DTI = 2,000 ÷ 6,000 = 33.3%
Back-End DTI
Total DTI = Total Monthly Debts ÷ Gross Monthly Income
Example: Total debts $2,580, income $6,000/mo → DTI = 2,580 ÷ 6,000 = 43%
Discount Points
1 Point = 1% of Loan Amount
Example: 2 points on $300,000 loan = 0.02 × $300,000 = $6,000
Monthly P&I Payment
Monthly P&I = (Loan Amount ÷ 1,000) × Monthly Factor
Example: $250,000 loan, factor 6.32/1000 → (250,000 ÷ 1,000) × 6.32 = $1,580/mo
Down Payment
Down Payment = Purchase Price × Down Payment %
Example: Purchase $350,000, 20% down → $350,000 × 0.20 = $70,000
Loan Amount
Loan Amount = Purchase Price − Down Payment
Example: Purchase $350,000, down $70,000 → Loan = $280,000
