Learning Objectives

Upon completing this chapter, you will be able to:

Distinguish between nominal interest rates, annual percentage rates (APR), and the factors that drive rate movements.

Explain the purpose and calculation of discount points and origination points, including their tax and disclosure implications.

Compare and contrast fixed-rate, adjustable-rate, and hybrid mortgage products, including their index, margin, caps, and negative amortization features.

Identify the defining characteristics of government-insured loans (FHA, VA, USDA) and conventional conforming/non-conforming loans.

Recall the statutory and regulatory references that govern rate disclosures, loan program parameters, and consumer protections.

Recognize common exam traps involving rate calculations, rescission periods, and tolerance categories.

1.1 The Interest Rate: Nominal vs. APR

The nominal interest rate (also called the note rate or contract rate) is the percentage charged on the principal balance, expressed annually. It determines the monthly principal and interest payment. The annual percentage rate (APR) is a broader measure required by the Truth in Lending Act (TILA), implemented by Regulation Z (12 CFR 1026) . The APR reflects the total cost of credit over the loan term, including the nominal rate, certain prepaid finance charges, points, origination fees, mortgage insurance premiums (in most cases), and other lender fees. The APR is almost always higher than the nominal rate on a loan with upfront costs.

Candidates must remember that the APR is not used to calculate the payment. It exists solely to provide a standardized comparison of credit costs. The APR is disclosed on the Loan Estimate and the Closing Disclosure under the TILA-RESPA Integrated Disclosure (TRID) rule, which implements both TILA and RESPA (12 U.S.C. 2601). The APR must be disclosed within three business days of loan application (Loan Estimate) and again at closing (Closing Disclosure).

Rate lock is a lender's commitment to hold a specific interest rate and points for a set period, typically 30, 45, or 60 days. A rate lock protects the borrower from market fluctuations. If rates fall after a lock, the borrower may have a "float-down" option (often for a fee) or may lose the benefit. If rates rise, the lock protects the borrower. The lock agreement must be in writing and should specify the expiration date. A lock that expires before closing may require a fee to extend.

1.2 Points: Discount and Origination

Points are prepaid interest or fees expressed as a percentage of the loan amount. One point equals one percent of the loan amount (e.g., one point on a $200,000 loan equals $2,000).

Discount points are paid to reduce the interest rate. Each discount point typically lowers the rate by 0.125% to 0.25%, depending on the lender and market. Discount points are considered prepaid interest and are tax-deductible (subject to IRS rules) if itemized. Under TILA, discount points are included in the finance charge and therefore in the APR calculation.

Origination points (or origination fees) are charged by the lender for processing and underwriting the loan. They are not tied to the rate. Origination points are also included in the finance charge for APR purposes. On the Loan Estimate and Closing Disclosure, origination charges appear in Section A (Origination Charges) while discount points appear separately but within the same section.

A key exam distinction: Discount points lower the rate; origination points pay for the loan's creation. Borrowers who plan to hold a loan for a long time may benefit from paying discount points (break-even analysis). The break-even period is the number of months it takes for the monthly payment savings to exceed the upfront cost of the points.

1.3 Fixed-Rate Mortgages

A fixed-rate mortgage (FRM) has an interest rate that remains constant for the entire loan term. The most common terms are 30-year and 15-year, though 20-year and 10-year products exist. The payment (principal and interest) is amortized over the term, meaning each payment includes both interest and a portion of principal. Early payments are interest-heavy; later payments are principal-heavy.

Key features:

No payment shock from rate changes.

Predictable budgeting.

Higher initial rate compared to an adjustable-rate mortgage (ARM) at origination.

Statutory note: The SAFE Act (12 U.S.C. 5101) does not govern loan products, but it requires state-licensed MLOs to know the products they sell. Fixed-rate loans are straightforward; however, exam questions often test the difference between fully amortizing, interest-only, and negative amortization loans. A fully amortizing fixed-rate loan pays off the balance by the end of the term. An interest-only loan (typically for the first 5–10 years) has lower payments but no principal reduction during the interest-only period. A negative amortization loan allows the payment to be less than the interest due, causing the principal balance to increase.

1.4 Adjustable-Rate Mortgages (ARMs)

An adjustable-rate mortgage has an interest rate that changes periodically based on an underlying index. The key components are:

Index: A published rate (e.g., SOFR, CMT, LIBOR is being phased out) that is beyond the lender's control.

Margin: A fixed percentage added to the index to determine the fully indexed rate. The margin is constant for the life of the loan.

Fully indexed rate = Index + Margin.

Initial rate: Often a "teaser" rate lower than the fully indexed rate.

Adjustment period: How often the rate changes (e.g., annually).

Caps: Limits on how much the rate or payment can change. Periodic caps limit the change per adjustment; lifetime caps limit the total increase over the loan term. There are also floor caps (minimum rate). Payment caps limit the payment increase but may cause negative amortization if the payment increase is less than the interest due.

Common ARM structures:

3/1 ARM: Fixed for 3 years, then adjusts annually.

5/1 ARM: Fixed for 5 years, then adjusts annually.

7/1 ARM, 10/1 ARM: Similar with longer fixed periods.

Disclosure requirements: Under Regulation Z, the lender must provide ARM disclosures at application, including a historical example of how the index has changed, the initial and maximum payments, and a statement that the borrower may qualify for a different loan amount based on the fully indexed rate (not the teaser rate). The Consumer Financial Protection Bureau (CFPB) requires lenders to underwrite ARMs at the fully indexed rate, not the introductory rate, to prevent payment shock.

Negative amortization occurs when the payment is insufficient to cover the interest due. The shortfall is added to the principal. Regulation Z requires that negative amortization loans include a warning and that the lender disclose the potential for increased principal. Some ARMs have a "payment option" feature allowing the borrower to choose a minimum payment, interest-only payment, or fully amortizing payment. These are high-risk and subject to stricter rules under the Ability-to-Repay (ATR) rule (Regulation Z, 12 CFR 1026.43).

1.5 Hybrid and Specialty Products

Hybrid ARMs combine a fixed-rate period with an adjustable period (e.g., 5/1). They are popular because the initial rate is lower than a 30-year fixed but offers stability for the first few years.

Balloon mortgages have a short term (5–7 years) with a large final payment (the balloon) that pays off the remaining balance. They are not fully amortizing. Balloon loans are generally prohibited for "higher-priced mortgage loans" under the ATR rule unless they meet specific exemptions (e.g., certain community bank loans).

Reverse mortgages (Home Equity Conversion Mortgages, HECMs) are for borrowers aged 62 or older. They allow the borrower to convert home equity into cash without monthly payments. The loan is repaid when the borrower dies, sells the home, or permanently moves out. Reverse mortgages are insured by the Federal Housing Administration (FHA) and are governed by specific HUD rules. The borrower must receive counseling from a HUD-approved counselor.

Interest-only loans and payment-option ARMs are considered non-traditional products. Under Regulation Z, lenders must verify the borrower's ability to repay the loan at the fully indexed rate with a fully amortizing payment schedule.

1.6 Government-Insured Loans

FHA Loans (Federal Housing Administration)

FHA loans are insured by the FHA, part of HUD. They are popular for first-time homebuyers due to low down payment requirements (as low as 3.5%). Key features:

Mortgage insurance premium (MIP) is required: an upfront MIP (UFMIP) of 1.75% of the base loan amount and an annual MIP paid monthly.

FHA loans are not made by the government; they are made by approved lenders and insured by the FHA.

FHA loan limits vary by county.

The borrower must have a minimum credit score (typically 580 for 3.5% down; 500–579 for 10% down).

FHA loans are assumable (subject to lender approval).

VA Loans (Department of Veterans Affairs)

VA loans are guaranteed by the VA and available to eligible veterans, active-duty service members, and certain reservists and surviving spouses. Key features:

No down payment required (100% financing).

No monthly mortgage insurance; instead, a one-time VA funding fee is charged (waived for veterans with service-connected disabilities).

The VA does not set a minimum credit score, but lenders may impose their own.

VA loans have no prepayment penalty.

The Certificate of Eligibility (COE) is required to prove eligibility.

USDA Loans (U.S. Department of Agriculture)

USDA Rural Development loans are for low- to moderate-income borrowers in eligible rural and suburban areas. Key features:

No down payment required (100% financing).

Two types: Guaranteed loans (through approved lenders) and Direct loans (from USDA).

An upfront guarantee fee and an annual fee are required.

Income limits apply based on area median income.

The property must be located in an eligible rural area as defined by USDA.

1.7 Conventional Loans and Conforming Limits

Conventional loans are not insured or guaranteed by a government agency. They are either conforming (meet the loan limits and standards set by Fannie Mae and Freddie Mac, the government-sponsored enterprises, or GSEs) or non-conforming (exceed those limits or fail other standards, such as jumbo loans).

Conforming loan limit (CLL): For 2024, the baseline conforming limit for a single-family home is $766,550 (higher in certain high-cost areas). This limit is set annually by the Federal Housing Finance Agency (FHFA). Loans above this limit are called jumbo loans and typically carry higher interest rates and stricter underwriting.

Private mortgage insurance (PMI): Conventional loans with a down payment of less than 20% require PMI. PMI protects the lender, not the borrower. PMI can be canceled once the borrower reaches 20% equity (based on the original property value) and must be automatically canceled at 22% equity, per the Homeowners Protection Act of 1998 (12 U.S.C. 4901). This is a common exam topic.

Mortgage insurance vs. hazard insurance: Mortgage insurance protects the lender against borrower default; hazard insurance (homeowners insurance) protects the property against damage. They are not interchangeable.

1.8 Rate and Fee Disclosures: TRID and Timing

The TILA-RESPA Integrated Disclosure (TRID) rule, effective October 2015, replaced the early TILA disclosure and the Good Faith Estimate (GFE) with the Loan Estimate (LE) and replaced the final TILA disclosure and HUD-1 with the Closing Disclosure (CD) .

Loan Estimate (LE):

Must be provided within three business days of receiving the borrower's application (defined as the six pieces of information: name, income, social security number, property address, estimated property value, and loan amount).

Contains the loan terms, projected payments, closing costs, APR, and total interest percentage (TIP).

The LE must be provided before the borrower is charged any fee other than a credit report fee.

Closing Disclosure (CD):

Must be provided at least three business days before loan closing.

If the APR increases by more than 0.125% (0.25% for irregular loans), the CD must be re-disclosed and a new three-business-day waiting period begins.

Other changes that trigger a new waiting period: a change to the loan product (e.g., fixed to ARM) or the addition of a prepayment penalty.

Tolerance categories: The CD has three tolerance levels for closing costs:

94.Zero tolerance: Fees that cannot increase at all from the LE (e.g., lender origination charges, points, transfer taxes, fees paid to the lender or its affiliate).

95.10% tolerance: Fees that can increase in aggregate by no more than 10% (e.g., recording fees, title services, third-party services where the borrower did not shop).

96.No tolerance: Fees that can increase by any amount if the borrower chooses a different service provider (e.g., title insurance if the borrower selects their own provider).

Right of Rescission: Under TILA, for loans secured by the borrower's principal dwelling (not for purchase-money mortgages), the borrower has three business days to rescind the loan after closing. The rescission period ends at midnight of the third business day after closing, or after delivery of the material disclosures, whichever is later. This is often confused with the TRID three-business-day CD delivery rule. The rescission right does not apply to purchase-money loans or initial construction loans.

1.9 Fair Lending and Disclosure Statutes

ECOA (Equal Credit Opportunity Act), Regulation B (12 CFR 1002): Prohibits discrimination based on race, color, religion, national origin, sex, marital status, age, or receipt of public assistance. Lenders must provide an adverse action notice within 30 days of a credit denial.

FCRA (Fair Credit Reporting Act): Governs the use of credit reports. Lenders must provide a notice if information from a credit report is used adversely. Borrowers have the right to a free credit report annually from each of the three major bureaus.

HMDA (Home Mortgage Disclosure Act), Regulation C (12 CFR 1003): Requires lenders to report loan data (race, ethnicity, sex, income, loan amount) to regulators for fair lending monitoring.

GLBA (Gramm-Leach-Bliley Act): Requires lenders to protect borrower nonpublic personal information and provide a privacy notice annually.

FDCPA (Fair Debt Collection Practices Act): Governs third-party debt collectors, not original lenders. Prohibits harassment, false statements, and unfair practices.

UDAAP (Unfair, Deceptive, or Abusive Acts or Practices): Under the Dodd-Frank Act, the CFPB prohibits acts that are unfair, deceptive, or abusive. This is a broad standard covering marketing, servicing, and origination practices.

SAFE Act (12 U.S.C. 5101): Requires MLOs to be licensed or registered, complete pre-licensure education, pass a national test, and undergo background checks.

1.10 Common Exam Traps

109.Confusing the rescission period with the CD delivery period. The three-business-day rescission right applies to refinances and home equity loans on the principal dwelling. The three-business-day CD review period applies to all closed-end loans (including purchases). They are separate requirements. A purchase loan has no rescission right, but it still requires the CD three days before closing.

110.APR vs. note rate. Candidates often think the APR is the rate used to calculate the monthly payment. It is not. The APR is a cost-of-credit measure. The note rate determines the payment.

111.Discount points vs. origination points. Discount points lower the rate; origination points are a fee for the lender's services. Both are finance charges under TILA, but only discount points are tax-deductible as prepaid interest.

112.PMI cancellation. PMI on conventional loans must be canceled at 22% equity (automatic) or at the borrower's request at 20% equity. FHA MIP, however, generally lasts for the life of the loan (for loans after June 3, 2013, with less than 10% down) or for 11 years (with 10% or more down). Candidates often apply the PMI rule to FHA loans.

113.Conforming limit confusion. The conforming limit is set by FHFA, not by Fannie Mae or Freddie Mac directly. The limit applies to conventional loans, not FHA or VA loans (which have their own limits).

114.ARM underwriting. Lenders must qualify borrowers at the fully indexed rate, not the teaser rate. Candidates often think the initial rate is used for qualification.

115.Zero tolerance items. Candidates often assume all third-party fees are within the 10% tolerance. In fact, if the borrower uses a provider chosen by the lender, the fee is zero tolerance. If the borrower shops and chooses their own provider, the fee has no tolerance limit.

116.Negative amortization. A payment cap that limits payment increases can cause negative amortization. Candidates often confuse payment caps with interest rate caps. Interest rate caps limit rate changes; payment caps limit payment changes, potentially causing deferred interest.

117.VA funding fee vs. MIP. The VA funding fee is not mortgage insurance. It is a one-time fee that can be financed into the loan. FHA has both upfront and annual MIP. USDA has guarantee and annual fees.

118.The SAFE Act test content. The national test with uniform state content includes federal law, general mortgage knowledge, and ethics. Candidates must know that the SAFE Act itself does not set interest rates or loan limits; it regulates MLO licensing and conduct.

1.11 Summary

This chapter covered the core elements of rates, points, and loan programs. You must be able to distinguish the note rate from the APR, explain how discount and origination points affect the loan, and compare fixed, adjustable, and government-insured products. You must also know the statutory framework: TILA/Regulation Z for disclosures, RESPA for settlement, TRID for integrated forms, ECOA for fair lending, and the SAFE Act for licensing. Memorize the timing rules (three business days for LE and CD, three business days for rescission), the tolerance categories, and the specific program parameters for FHA, VA, and USDA loans. The exam rewards precision—do not confuse similar-sounding rules, and always anchor your answer in the specific statute or regulation that governs the issue.
