3.1 Mortgage Products and Types
Key Takeaways
- Fixed-rate mortgages offer payment stability with the same interest rate and principal/interest payment for the entire loan term (typically 15 or 30 years)
- Adjustable-rate mortgages (ARMs) feature an initial fixed period (commonly 5/1, 7/1, or 10/1) after which the rate adjusts annually based on an index plus margin
- ARM rate caps include periodic caps (typically 2% per adjustment), lifetime caps (typically 5-6% over initial rate), and initial adjustment caps (often 2-5%)
- Interest-only loans allow borrowers to pay only interest for an initial period (5-10 years) before converting to fully amortizing payments, resulting in payment shock
- Home equity loans provide lump-sum fixed-rate financing while HELOCs offer revolving credit lines with variable rates, both secured by home equity
- Reverse mortgages (HECMs) allow homeowners 62+ to convert home equity to cash with no monthly payments required; the loan comes due when the borrower moves, sells, or dies
Mortgage Products and Types
Understanding the full range of mortgage products is essential for MLO exam success and for helping borrowers find the right financing. This section covers the major loan types you'll encounter in practice.
Fixed-Rate Mortgages (FRMs)
A fixed-rate mortgage maintains the same interest rate throughout the entire loan term. This is the most common and straightforward mortgage type.
Key Characteristics
| Feature | Description |
|---|---|
| Interest Rate | Locked for entire term |
| Monthly Payment | Principal and interest remain constant |
| Common Terms | 30 years, 15 years, 20 years, 10 years |
| Predictability | Highest payment stability |
30-Year vs. 15-Year Fixed
| Factor | 30-Year Fixed | 15-Year Fixed |
|---|---|---|
| Monthly Payment | Lower | Higher |
| Total Interest Paid | More | Less |
| Interest Rate | Slightly higher | Typically 0.5-0.75% lower |
| Equity Building | Slower | Faster |
| Best For | Cash flow flexibility | Faster payoff, interest savings |
Example Comparison
For a $300,000 loan at 6.5% vs. 6.0%:
- 30-year at 6.5%: $1,896/month, $382,633 total interest
- 15-year at 6.0%: $2,532/month, $155,683 total interest
The 15-year saves over $225,000 in interest but requires $636 more per month.
Adjustable-Rate Mortgages (ARMs)
An adjustable-rate mortgage (ARM) has an interest rate that changes periodically based on market conditions. ARMs typically offer lower initial rates in exchange for rate uncertainty later.
ARM Structure
ARMs are described using two numbers (e.g., 5/1, 7/1, 10/1):
- First number: Initial fixed-rate period (years)
- Second number: Adjustment frequency after fixed period
Common ARM Types
| ARM Type | Fixed Period | Then Adjusts |
|---|---|---|
| 5/1 ARM | 5 years | Annually |
| 7/1 ARM | 7 years | Annually |
| 10/1 ARM | 10 years | Annually |
| 5/6 ARM | 5 years | Every 6 months |
How ARM Rates Adjust
The new rate is calculated as: Index + Margin = Fully Indexed Rate
| Component | Description |
|---|---|
| Index | Market benchmark (SOFR, Treasury) |
| Margin | Lender's fixed profit (typically 2-3%) |
| Caps | Limits on rate changes |
ARM Rate Caps
Rate caps protect borrowers from extreme rate increases:
| Cap Type | Typical Limit | Example |
|---|---|---|
| Initial Adjustment Cap | 2% or 5% | Rate can rise max 2% at first adjustment |
| Periodic Cap | 2% | Rate can rise max 2% per adjustment period |
| Lifetime Cap | 5-6% | Rate can never exceed initial rate + 5-6% |
ARM Example
A 5/1 ARM starts at 5.5% with 2/2/5 caps and 2.75% margin:
- Years 1-5: Rate fixed at 5.5%
- Year 6: Rate can adjust up to 7.5% (5.5% + 2% initial cap)
- Each Year After: Rate can move up or down 2%
- Maximum Ever: 10.5% (5.5% + 5% lifetime cap)
Interest-Only Mortgages
Interest-only mortgages allow borrowers to pay only the interest for an initial period before transitioning to fully amortizing payments.
Key Features
| Feature | Description |
|---|---|
| Initial Period | Typically 5-10 years |
| Initial Payment | Interest only (lower) |
| After I/O Period | Fully amortizing (higher) |
| Principal | No reduction during I/O period |
Payment Shock Example
For a $400,000 loan at 7%:
- Interest-Only Payment: $2,333/month
- After I/O Period (20-year amortization): $3,102/month
- Payment Increase: $769/month (33% jump)
Who Uses Interest-Only Loans
- Borrowers expecting significant income increases
- Real estate investors focused on cash flow
- Borrowers planning to sell before I/O period ends
- High-net-worth borrowers with non-traditional income
Regulatory Concerns
Under ATR/QM rules, interest-only loans are non-QM products because:
- They don't fully amortize during the loan term
- Payment shock creates affordability concerns
- Underwriting must account for the higher future payment
Balloon Mortgages
A balloon mortgage requires a large lump-sum payment (the "balloon") at the end of a shorter term.
Structure
| Feature | Description |
|---|---|
| Term | Typically 5-7 years |
| Payments | Based on 30-year amortization |
| Balloon Payment | Remaining balance due at term end |
| Monthly Payment | Lower than fully amortizing |
Example
$300,000 balloon mortgage at 6.5% with 7-year term:
- Monthly payment: $1,896 (based on 30-year schedule)
- Balance due in Year 7: ~$273,000 (balloon payment)
Risks
- Borrower must refinance, pay off, or sell at maturity
- Interest rate and qualification uncertainty at balloon date
- Non-QM product under current regulations
Reverse Mortgages (HECMs)
A Home Equity Conversion Mortgage (HECM) allows homeowners age 62 or older to convert home equity into cash without monthly payments.
How Reverse Mortgages Work
| Feature | Description |
|---|---|
| Eligibility | Homeowner 62+ years old |
| Property | Primary residence |
| Payments | No monthly mortgage payments required |
| Repayment | Due when borrower dies, moves, or sells |
| Loan Amount | Based on age, home value, interest rate |
Disbursement Options
| Option | Description |
|---|---|
| Lump Sum | One-time payment (fixed rate only) |
| Monthly Payments | Regular income stream |
| Line of Credit | Draw as needed (grows over time) |
| Combination | Mix of above options |
Required Counseling
Borrowers must complete HUD-approved counseling before closing a HECM. This is mandatory, not optional.
Key Protections
- Non-recourse: Borrower/heirs never owe more than home value
- FHA insurance: Protects lender if balance exceeds value
- Ongoing obligations: Borrower must pay taxes, insurance, maintain property
Home Equity Loans vs. HELOCs
Both allow borrowing against home equity but work differently.
Comparison
| Feature | Home Equity Loan | HELOC |
|---|---|---|
| Disbursement | Lump sum | Revolving credit line |
| Interest Rate | Fixed | Usually variable |
| Payments | Fixed monthly | Varies with balance/rate |
| Term | Fixed (10-30 years) | Draw period + repayment period |
| Best For | Known, one-time expense | Ongoing or uncertain needs |
HELOC Structure
| Phase | Typical Length | Description |
|---|---|---|
| Draw Period | 10 years | Borrow up to limit, interest-only minimum |
| Repayment Period | 10-20 years | No new draws, fully amortizing |
Lien Position
Both home equity loans and HELOCs are typically second liens (junior to the first mortgage), which means:
- Higher interest rates than first mortgages
- In foreclosure, paid after first mortgage
- Combined loan-to-value (CLTV) typically capped at 80-90%
Jumbo Loans
Jumbo loans exceed the conforming loan limits set by FHFA for Fannie Mae and Freddie Mac.
2026 Conforming Loan Limits
| Area Type | Single-Family Limit |
|---|---|
| Standard Areas | $806,500 (2026) |
| High-Cost Areas | Up to $1,209,750 (2026) |
| Alaska/Hawaii | Up to $1,209,750 |
Jumbo Loan Characteristics
| Feature | Typical Requirement |
|---|---|
| Credit Score | 700-720+ minimum |
| Down Payment | 10-20%+ |
| DTI Ratio | Often stricter (36-43%) |
| Reserves | 6-12 months required |
| Documentation | Full doc typically required |
Why Jumbo Rates Differ
Jumbo loans carry more risk because:
- No government guarantee (Fannie/Freddie/FHA)
- Larger loss exposure for lender
- Limited secondary market liquidity
- Often held in lender portfolio
Choosing the Right Product
| If Borrower Needs... | Consider... |
|---|---|
| Payment stability | Fixed-rate mortgage |
| Lowest initial payment | ARM or interest-only |
| Shorter ownership | ARM (5/1 or 7/1) |
| Supplement retirement | Reverse mortgage (62+) |
| One-time expense | Home equity loan |
| Flexible access to equity | HELOC |
| Loan > conforming limits | Jumbo loan |
Key Takeaways
- Fixed-rate mortgages offer the most payment predictability
- ARMs have lower initial rates but rate uncertainty after the fixed period
- Rate caps protect ARM borrowers from extreme rate increases
- Interest-only and balloon loans are non-QM products with payment shock risk
- Reverse mortgages require mandatory counseling and age 62+ eligibility
- HELOCs offer flexibility while home equity loans provide certainty
- Jumbo loans exceed conforming limits and have stricter requirements
