General Mortgage Knowledge

  • Loan-to-value (LTV) = loan amount / appraised value or purchase price, whichever is lower; combined LTV (CLTV) = (first lien + all subordinate liens) / value.

  • Front-end ratio = housing expense (PITI + HOA) / gross monthly income; back-end ratio = total monthly debt obligations / gross monthly income.

  • Conventional conforming loan limits are set annually by FHFA; loans above the limit are non-conforming jumbo loans.

  • FHA loans require mortgage insurance premium (MIP) and have lower credit score and down payment thresholds; VA loans require no down payment and a funding fee; USDA loans are for rural eligible areas.

  • Fixed-rate mortgages have constant principal and interest payments; adjustable-rate mortgages have an initial fixed period followed by periodic adjustments tied to an index plus margin.

  • An amortization schedule shows how much of each payment goes to principal versus interest; early payments are interest-heavy because interest is computed on the outstanding balance.

  • Discount points are prepaid interest that lower the note rate; origination fees compensate the lender for processing the loan.

  • Escrow/impound accounts collect monthly portions of property taxes and hazard insurance so the servicer can pay them when due.

  • A deed of trust uses a trustee to hold title as security, while a mortgage uses a mortgagee; both secure the note and can be foreclosed.

Mortgage Loan Origination Activities

  • The loan application is the trigger for disclosures; the Loan Estimate must be delivered within 3 business days and the borrower must receive it before closing.

  • A complete application includes the borrower's name, income, Social Security number, property address, estimated value, and loan amount.

  • Adverse action notice is required when an application is denied, counteroffered, or not funded; the notice must state the action, the specific reasons, and ECOA rights.

  • Verification documents typically include pay stubs, W-2s, tax returns, bank statements, and a credit report; self-employed borrowers generally need 2 years of returns.

  • A rate lock agreement states the locked rate, lock period, and any float-down or extension terms; a lock expiring before closing may cause a new rate or fee.

  • The Closing Disclosure lists the loan terms, projected payments, closing costs, and cash to close; the borrower must receive it 3 business days before consummation.

  • The appraisal supports the value used for LTV; a low appraisal may require a revised loan amount, additional down payment, or a new loan.

  • The MLO must provide the borrower with the NMLS Unique Identifier on written solicitation and business cards, and must keep records of the loan file.

  • Pre-approval is a conditional commitment based on verified income and credit; pre-qualification is an unverified estimate of borrowing capacity.

Ethics

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

  • Steering a borrower to a higher-cost loan or a lender that pays a higher yield spread premium without disclosure violates RESPA and TILA.

  • Dual compensation (receiving fees from both borrower and lender) must be disclosed and may be restricted; undisclosed compensation is a violation.

  • Fair lending requires consistent treatment of similarly situated applicants; disparate treatment can be shown by comparing files with similar credit profiles.

  • Redlining is denying or discouraging applications based on the racial or ethnic composition of a neighborhood; it violates the Fair Housing Act and ECOA.

  • Predatory lending indicators include equity stripping, excessive fees, prepayment penalties, balloon payments, and loan flipping without a net tangible benefit.

  • Confidential borrower information must be protected under the Gramm-Leach-Bliley Act; sharing nonpublic personal information requires privacy notices and opt-out rights.

  • An MLO must not falsify income, asset, or occupancy information; occupancy fraud (claiming a primary residence for an investment property) is a federal offense.

  • Conflicts of interest must be disclosed in writing; referral relationships with real estate agents or builders cannot involve undisclosed payments.
