Home equity and helocs

Does your product fit here?

Home equity products are secured by residential real estate where you hold a subordinate lien position. The first mortgage holder gets paid first. You get paid second (or not at all) if the property is liquidated. That subordinate position drives everything about how this asset class prices, structures, and performs through housing cycles.

Products that fit here:

Home equity loans (HEL): Closed-end second lien, fixed rate, fully amortizing over 5-30 years. Borrower receives a lump sum at closing. Used for debt consolidation, home improvement, major purchases. The dominant product before 2008, now making a comeback as rates rose.
Home equity lines of credit (HELOC): Open-end revolving credit secured by the home. Draw period (typically 10 years) during which borrower can access funds, followed by repayment period (typically 20 years). Variable rate tied to Prime. The preferred home equity product from 2010-2023 due to flexibility and lower initial payments.
Piggyback loans: 80/10/10 or 80/15/5 structures where a second lien is originated simultaneously with a first to avoid PMI or reach a lower LTV on the first. Legally a separate loan with its own subordinate lien.
Cash-out second liens: Second mortgage taken after origination of the first, with proceeds to the borrower. Same economics as a HEL.

What does NOT fit here:

First lien mortgages: Even if cash-out, a first lien is not a home equity product. See Agency RMBS or Non-Agency RMBS.
Home improvement loans without a lien: If you’re lending for home improvement but not taking a lien on the property, that’s unsecured consumer. The presence of a perfected lien is the distinction.
Reverse mortgages: Different borrower profile (62+), different cash flow pattern (no payments until death/sale), different regulatory regime (FHA HECM or proprietary). Specialty asset class.
PACE loans: Property Assessed Clean Energy financing is secured by a tax lien, not a mortgage lien. Different priority, different regulatory treatment. See Solar / Renewable Energy.

Edge cases

Closed-end second liens in repayment only: If you acquired a portfolio of legacy HELOCs that have all converted to repayment phase, treat them as closed-end seconds for analysis purposes. No draw risk remains.

Investment property second liens: Second liens on 1-4 unit rental properties are home equity products but carry higher risk. Occupancy type affects loss severity significantly. Expect 5-10% lower advance rates vs. owner-occupied.

Manufactured housing with land: If the manufactured home is titled as real property (not chattel) and sits on land the borrower owns, a second lien is technically a home equity product. In practice, most capital providers treat manufactured as a separate asset class due to different depreciation dynamics.

Simultaneous second liens (piggybacks): These are legally home equity products but often analyzed alongside the first lien for CLTV purposes. Capital providers may request combined first/second lien tape data.

How lenders will classify you

Credit Tier	FICO	Max CLTV	Advance Rate (Warehouse)	Pricing
Super-prime	740+	80%	85-92%	SOFR + 175-250 bps
Prime	680-739	85%	78-88%	SOFR + 225-325 bps
Near-prime	620-679	90%	68-78%	SOFR + 325-450 bps
Expanded	<620	90%	55-70%	SOFR + 425-600 bps

Illustrative pricing. See pricing disclaimer.

The CLTV constraint matters more than FICO for second liens. A 750 FICO borrower at 95% CLTV is riskier than a 680 FICO borrower at 70% CLTV.

Market benchmarks and comps

Performance benchmarks by product type and credit tier

Home Equity Loans (Closed-End)

Metric	Prime (680+, <80% CLTV)	Near-Prime (620-679, <85% CLTV)	Expanded (<620 or >85% CLTV)
CDR (annualized)	0.3-1.0%	1.5-4.0%	4.0-10.0%
CNL (life of pool)	1.0-3.0%	4.0-10.0%	10.0-25.0%
CPR (annualized)	15-25%	12-20%	8-15%
Loss severity	85-100%	90-100%	95-100%
WAL	3.5-5.5 yrs	3.5-5.5 yrs	4.0-6.0 yrs

HELOCs

Metric	Prime (680+, <80% CLTV)	Near-Prime (620-679, <85% CLTV)	Expanded
CDR (draw period)	0.2-0.8%	1.0-3.0%	3.0-8.0%
CDR (repayment period)	0.8-2.0%	2.5-6.0%	6.0-15.0%
Loss severity	85-100%	90-100%	95-100%
Draw rate (% of line)	40-60%	50-70%	60-80%

Note the CDR jump from draw period to repayment period. During the draw period, HELOCs are interest-only or minimum payment. When repayment begins, the payment shock causes elevated defaults, particularly for borrowers who have fully drawn their line.

The severity reality for second liens

Unlike first lien mortgages where you can foreclose and recover 60-80% of the loan balance, second liens sit behind the first. In a foreclosure or short sale:

The first lien gets paid in full (or takes the loss)
The second lien gets whatever remains (often nothing)

Severity by scenario:

Scenario	First Lien Recovery	Second Lien Recovery	Second Lien Severity
Foreclosure, CLTV <85%	Full	40-70%	30-60%
Foreclosure, CLTV 85-95%	Full	0-30%	70-100%
Foreclosure, CLTV >95%	Partial	0%	100%
Short sale	Varies	0-5%	95-100%
Deed-in-lieu	Full (typically)	0-10%	90-100%

The practical assumption: model second lien severity at 90-100%. If home prices decline and CLTVs rise, assume 100%.

Prepayment dynamics

HEL (closed-end):

Rate-sensitive: falling mortgage rates trigger refinancing that pays off the second
Home sale: pays off both first and second
Death/estate settlement: accelerated payoff
Base case CPR: 15-25% for prime, declining with credit quality

HELOC:

Less rate-sensitive during draw period (revolving, can redraw)
Line closure at property sale
Utilization fluctuates with borrower needs
Repayment period CPR increases as borrowers seek to eliminate the obligation

What “good” performance looks like

Prime HEL CDR below 1.0% through month 36
HELOC draw period CDR below 0.8% for prime
HELOC repayment conversion CDR spike limited to 1.5x draw period CDR
CNL tracking below rating agency assumptions at each seasoning point
No CLTV drift above 5% from origination values (stable to rising home prices)

Red flag performance benchmarks

CDR exceeding 1.5x base case for 3+ consecutive months
30+ DPD delinquency rising without seasonal explanation
HELOC draw rates spiking above 80% (borrowers tapping emergency liquidity)
Mark-to-market CLTV rising above 90% for more than 10% of the pool
Vintage-over-vintage deterioration at the same seasoning point

What lenders and investors focus on

1. Combined loan-to-value (CLTV)

CLTV is the single most important risk metric for second liens. It determines your cushion before you’re underwater in a liquidation scenario.

CLTV = (First Lien Balance + Second Lien Balance) / Property Value

Example: $300K property, $200K first, $50K second = 83.3% CLTV

What capital providers want to see:

CLTV Band	Risk Assessment	Typical Treatment
<70%	Low risk	Full advance rate, tightest pricing
70-80%	Moderate risk	Standard terms
80-85%	Elevated risk	3-5% advance rate haircut
85-90%	High risk	5-10% haircut, may require MI
>90%	Stressed	Often ineligible or heavily discounted

Mark-to-market CLTV matters more than origination CLTV. Capital providers require:

AVM refresh quarterly (minimum) or monthly for warehouse facilities
CLTV recalculation using current first lien balance (which amortizes) and refreshed property value
Concentration triggers if mark-to-market CLTV exceeds origination thresholds

The first lien balance tracking requirement is unique to this asset class. You need real-time (or near real-time) data on what the first lien holder is owed, which requires coordination with the first lien servicer or credit bureau pulls.

2. Credit score and credit profile

FICO thresholds by CLTV band:

CLTV	Minimum FICO (Prime)	Minimum FICO (Near-Prime)	Minimum FICO (Expanded)
<70%	660	580	500
70-80%	680	620	560
80-85%	700	660	620
85-90%	720	680	660
>90%	740+	700	Often not offered

Beyond FICO, capital providers examine:

Payment history on the first mortgage: 0x30 in the last 24 months is the gold standard. Any mortgage delinquency is a major risk factor.
Debt consolidation purpose: Borrowers using home equity to pay off credit cards often show temporary credit improvement followed by re-leveraging. Watch for credit utilization creep post-origination.
Recent inquiries: Multiple mortgage inquiries suggest shopping; multiple consumer credit inquiries suggest financial stress.

3. Property type and occupancy

Property Type	Default Risk	Severity Risk	Typical Treatment
Owner-occupied SFR	Baseline	Baseline	Full eligibility
Second home	+25-50% CDR	Similar	5% CLTV haircut
Investment 1-4 unit	+50-100% CDR	+10% severity	10% CLTV haircut, 5% advance rate reduction
Condo	+10-20% CDR	+5% severity	HOA lien priority analysis required
2-4 unit owner-occupied	+15-25% CDR	+5% severity	Rental income verification

Geographic concentration matters more for second liens than many asset classes because your performance is directly tied to local housing markets. Standard limits:

Single MSA: 15-20% maximum
Single state: 25-30% maximum
Correlation with first lien geographic exposure must be disclosed

4. First lien position and subordination

Your recovery depends entirely on what happens with the first lien. Key requirements:

Subordination agreement: Written agreement from the first lien holder acknowledging the second lien and specifying modification/refinance notification requirements. Without this, the first lien holder can refinance and wipe out your lien position.

First lien modification notification: If the first lien servicer modifies the loan (principal reduction, rate reduction, term extension), they must notify you. Principal increases or new advances that increase the first lien balance directly impair your recovery.

Cross-default provisions: Your loan documents should specify whether a default on the first lien constitutes a default on the second. Most structures include this provision.

First lien servicer risk: If the first lien servicer is uncooperative or goes into its own distress, your ability to coordinate loss mitigation or receive timely default notices is impaired.

5. HELOC-specific: draw period and utilization

For HELOCs, the funded balance today may not equal the funded balance tomorrow. Capital providers focus on:

Current utilization: Funded balance as a percentage of line amount

40-60% utilization is typical for performing prime HELOCs
Above 80% utilization suggests financial stress or emergency draw

Time remaining in draw period:

HELOCs early in draw period have more optionality risk (borrower can draw up to line limit)
HELOCs late in draw period are more predictable
HELOCs in repayment period are effectively closed-end seconds

Payment type during draw:

Interest-only during draw (most common): lower payment, higher payment shock at conversion
Minimum payment with some principal: smoother conversion but less common

Unfunded commitment exposure: For warehouse facilities financing HELOCs, the lender must understand their exposure to future draws. See structural section below.

Typical structures used

Warehouse facility

The standard structure for scaling home equity originators.

HEL (Closed-End):

Credit Tier	Advance Rate	Pricing
Prime (<80% CLTV)	85-92%	SOFR + 175-275 bps
Prime (80-85% CLTV)	80-88%	SOFR + 200-300 bps
Near-prime	70-82%	SOFR + 275-400 bps
Expanded	55-72%	SOFR + 375-550 bps

Illustrative pricing. See pricing disclaimer.

HELOC:

HELOC warehouse is more complex due to unfunded commitment exposure. Two approaches:

Funded-only facility: Warehouse advances only against drawn balances. Unfunded commitments are the originator’s exposure. Simpler but limits scaling.
Funded + unfunded facility: Warehouse advances against both drawn balances (higher advance rate) and a percentage of unfunded commitments (lower advance rate, typically 25-50%). Allows full balance sheet financing.

Component	Advance Rate	Notes
Funded balance	75-88%	Similar to HEL by credit tier
Unfunded commitment	25-50%	Lower due to uncertainty

Illustrative pricing. See pricing disclaimer.

Revolving period: 18-36 months typical Facility size: $50M-$500M

Term ABS

Home equity ABS was a dominant asset class pre-2008, collapsed during the financial crisis, and has slowly returned since 2015.

Historical context: In 2006, home equity ABS issuance exceeded $400B. By 2009, issuance was near zero. The market has rebuilt to $15-25B annually, but with much tighter underwriting standards.

Current market:

Structure	Typical Size	Credit Enhancement	Key Characteristics
Prime HEL	$200M-$500M	5-12% subordination (AAA)	Major bank issuers
Near-prime	$100M-$300M	15-25% subordination (AAA)	Non-bank and regional originators
HELOC	Less common	Higher enhancement	Draw risk complicates structuring

Major issuers (post-crisis): Figure Technologies, Spring EQ, Oportun (formerly Lending Point), regional banks, credit unions via aggregators.

Rating agencies: All major agencies rate home equity ABS. S&P and Moody’s have published updated criteria post-crisis with significantly higher stress assumptions.

Whole loan sale

Periodic or ongoing sale of originated loans to balance sheet buyers.

Bank buyers: Regional and community banks purchasing prime home equity for portfolio yield. Pricing: par minus 0-2 points for prime, larger discount for lower credit tiers.

Credit fund buyers: Purchasing near-prime and expanded credit at higher yields. Pricing: 8-15% target yield depending on credit quality.

Forward flow

Less common for home equity than consumer unsecured due to:

Larger average loan size (more lumpy)
Property-specific underwriting (harder to standardize)
First lien coordination requirements

When used, typically for prime HEL with standardized underwriting guidelines and established originator track record.

Asset-class-specific structural features

CLTV monitoring and mark-to-market

Unlike unsecured consumer loans where credit score is relatively stable, home equity credit quality can change dramatically based on property values.

AVM requirements:

Frequency: Monthly for warehouse, quarterly for term ABS
Acceptable providers: CoreLogic, Black Knight, First American, Clear Capital
Reconciliation: Material variance from origination value (>10%) requires review

CLTV drift triggers:

Event	Typical Consequence
Pool average CLTV rises 5%	Enhanced reporting requirement
Pool average CLTV rises 10%	Cash trapping or reserve funding
More than 20% of pool >90% CLTV	Ineligibility for new advances; may trigger early amortization
More than 10% of pool >100% CLTV	Potential acceleration event

Home price index adjustments: Some structures tie CLTV recalculation to regional or national home price indices (Case-Shiller, FHFA HPI) rather than individual AVMs. Simpler but less precise.

First lien tracking

Unique to this asset class: you need ongoing visibility into first lien status.

Tracking methods:

Credit bureau pulls: Monthly pulls show first lien balance and payment status. Limitation: may lag 30-60 days.
Servicer reporting: Direct feed from first lien servicer (if same servicer or cooperative arrangement). Most accurate but requires relationship.
Public records: Lien recordings show modifications but may miss payment status.

Subordination agreement provisions to negotiate:

Advance notice of refinancing (30-60 days minimum)
Consent required for balance increases above original amount
Notification of delinquency at 60+ days
Cure rights before first lien forecloses

First lien modification risk: If the first lien servicer grants a principal reduction under HAMP or a proprietary mod program, your CLTV improves. If they grant a balance increase (uncommon) or capitalize arrearages, your position worsens.

HELOC draw mechanics in warehouse

The unfunded commitment creates unique structuring challenges.

Draw rate assumptions:

Prime HELOCs: Assume 60-70% ultimate utilization
Near-prime: Assume 70-80%
Stressed: Assume 85-90%

Utilization caps:

Some structures cap funding against any HELOC where utilization exceeds a threshold (e.g., 85%)
Rationale: High utilization borrowers are either financially stressed or about to be

Advance rate on unfunded:

Component	Calculation	Example
Line amount	$100,000
Current draw	$50,000
Unfunded commitment	$50,000
Advance on funded (85%)	$42,500
Advance on unfunded (35%)	$17,500
Total advance	$60,000	60% of line

Interest rate mechanics

HEL (fixed rate):

Fixed rate at origination
No basis risk for issuer
Prepayment driven by rate movements (falling rates increase prepayment)

HELOC (variable rate):

Index: Prime Rate (most common) or SOFR
Margin: +0.50% to +3.00% depending on credit tier
Floor: Often Prime or a fixed floor (e.g., 4.00%)
Ceiling: State usury limits or contractual cap (e.g., 18-24%)

Interest rate mismatch: If you’re financing floating-rate HELOCs with fixed-rate term ABS, you have basis risk. Common solutions:

Issue floating-rate notes
Enter into interest rate swaps or caps
Use available funds cap provisions

Rating agency treatment

S&P approach

S&P uses a loan-level loss model incorporating:

CLTV stress: Property values stressed 10-30% at AAA level
CDR stress: 3-5x base case defaults
Severity curves: Tied to post-stress CLTV

Original CLTV	Property Value Stress (AAA)	Post-Stress CLTV	Severity Assumption
70%	-25%	93%	85%
80%	-25%	107%	100%
85%	-25%	113%	100%
90%	-25%	120%	100%

Key S&P considerations:

Seasoning credit: Loans with 24+ months of clean payment history get CDR relief
Geographic concentration: Penalty for single-MSA concentration above 15%
HELOC draw period: Higher stress during repayment conversion window

Moody’s approach

Moody’s emphasizes:

Originator assessment: Track record, financial strength, underwriting consistency
Loss timing: Earlier loss emergence for second liens vs. first
Servicer quality: Particularly important given first lien coordination requirements
Economic stress scenarios: Unemployment shocks and housing price correlation

Moody’s HELOC-specific:

Draw rate assumptions under stress (higher utilization = higher loss exposure)
Payment shock modeling at draw-to-repayment conversion

Typical credit enhancement levels

HEL (Closed-End)

Rating	Prime (<80% CLTV)	Near-Prime (<85% CLTV)	Expanded
AAA	8-14%	18-28%	30-45%
AA	5-10%	12-20%	22-35%
A	3-7%	8-15%	16-26%
BBB	2-4%	5-10%	10-18%

HELOC

Generally 3-5% higher enhancement than HEL due to unfunded commitment risk and payment shock at conversion.

Key stress scenarios

Base case: Your historical performance with modest deterioration
Moderate stress: Home prices flat, unemployment +2%, CDR 2x
Severe stress (AAA): Home prices -20%, unemployment +5%, CDR 4-5x
Extension scenario: CPR 0.5x base, losses extend and accumulate
HELOC payment shock: Model 2x CDR during 12-month window around repayment conversion

Diligence focus areas

Loan identifiers, origination date, current balance, original balance
Interest rate, rate type (fixed/variable), index and margin for variable
Term, remaining term, payment amount
FICO at origination, current FICO (if refreshed)
CLTV at origination, current CLTV
First lien balance (current), first lien servicer

Property valuation review

Capital providers will test whether your property values are reliable.

AVM reconciliation:

Compare origination appraisal to current AVM
Variance analysis: how many loans have AVM >10% different from appraisal?
Trend analysis: are AVMs showing appreciation consistent with local indices?

Sample appraisal review:

2-5% sample of full appraisal reports
Focus on: comparable selection, condition adjustments, market trend analysis
Red flags: desktop appraisals for high-CLTV loans, appraisals from a small number of AMCs

First lien tracking sample

Verification steps:

Confirm subordination agreement is on file for each loan
Match credit bureau first lien balance to loan tape data
Verify first lien payment status (0x30 requirement)
Check for any first lien modifications or refinances since origination

Common findings:

Missing subordination agreements (often 1-3% of pool)
First lien balance discrepancies from stale data
Undisclosed first lien modifications

Underwriting file review

Sample size: 50-100 loans for initial facility, ongoing sampling per draw

Focus areas:

Income verification documentation (pay stubs, tax returns, bank statements)
DTI calculation accuracy (all debts captured)
Appraisal or AVM in file
Title report confirming lien position
Signed subordination agreement
Proper disclosures (TILA, RESPA)

Servicer operations

First lien coordination:

Process for obtaining first lien balance updates
Notification procedures when first lien goes delinquent

Red flags and off-market characteristics

Performance red flags

CDR exceeding 1.5x base case for 2+ consecutive vintages at the same seasoning point
CLTV drift: Pool average mark-to-market CLTV rising more than 5% over 12 months without corresponding home price index decline (suggests stale origination values)
First lien delinquency correlation: If your seconds are current but the underlying firsts are going delinquent, losses are coming
HELOC draw rate spike: Utilization jumping from 55% to 75%+ in a quarter suggests borrower financial stress
HELOC payment shock losses: CDR during repayment conversion exceeding 2x draw period CDR indicates underwriting didn’t account for payment shock

Originator red flags

Rapid CLTV expansion: Increasing maximum CLTV from 80% to 90% without demonstrated track record at higher CLTV
Geographic concentration in declining markets: More than 25% in a single state with weakening housing fundamentals
Weak first lien tracking: No automated process for monitoring first lien status; manual-only or credit bureau-only with 60+ day lag
Appraisal quality concerns: Single AMC providing all appraisals, or desktop/AVM-only for high-CLTV loans
Income verification weakening: Shift from full doc to stated/lite doc without guideline disclosure
Volume growth exceeding 50% YoY: Aggressive growth in home equity typically precedes performance deterioration

Important: The 2006-2008 home equity crisis was driven by exactly this pattern: rapid CLTV expansion + aggressive volume growth + weakening income verification + home price concentration. Capital providers who lived through it will immediately flag these combinations.

Structural red flags

High CLTV concentration without enhancement: More than 30% of pool above 85% CLTV with less than 20% credit enhancement
HELOC unfunded commitment mismatch: Warehouse advancing 80% against funded + unfunded but assuming only 50% ultimate draw rate
Inadequate first lien subordination: Missing or incomplete subordination agreements, particularly for loans where first and second lien servicers differ
No CLTV monitoring covenant: Warehouse that doesn’t require AVM refresh and CLTV recalculation
Single-state concentration above 30%: Particularly in states with long foreclosure timelines (NY, NJ, FL) or judicial foreclosure requirements

Market cycle considerations

Second liens are highly cyclical. Your base case assumptions should account for:

Housing market correlation: When home prices decline:

CLTV rises mechanically
Severity increases (less equity cushion)
Borrowers more likely to default (negative equity reduces incentive to cure)
Strategic default risk increases (borrowers walk away from underwater homes)

First lien competition: In rising rate environments, first lien refinancing slows, which can increase home equity demand (borrowers tap equity via second lien rather than cash-out refi). This can support origination volume but may bring in lower-quality borrowers.

Lessons from 2008-2012:

Second lien losses reached 30-50% CNL at peak
Severity approached 100% for pools with average CLTV above 90%
Banks with large second lien portfolios (Bank of America, JPMorgan, Wells) took massive losses
The market essentially shut down for 5+ years

Capital providers with institutional memory price this risk into their advance rates and structural protections. If your origination program was launched post-2015, you may face additional scrutiny because your track record doesn’t include a stressed housing cycle.
