What do you need to qualify for a HELOC?

To qualify for a HELOC, most lenders want your first mortgage plus the new line to stay at or under 80% to 90% of your home's value, a credit score of 640 or higher, a debt-to-income ratio at or below roughly 45% to 50%, and income they can verify. Each of those limits comes from the individual lender's program matrix, so the same file can get different answers from different lenders.

A home equity line of credit (HELOC) is a revolving line secured by your home that you can draw on, repay and draw on again during a set draw period. The CFPB describes it as borrowing against your equity, which is your home's value minus what you owe on your mortgage.

The table below pulls common norms from public lender guidelines. Programs vary, and every approval is subject to underwriting.

Requirement	Common norm	Example from a public source
Equity (CLTV cap)	80% to 90% on a primary residence	Homebridge: 80% max. Spring EQ: 90% at a 680+ score
Credit score	Floors from 640 up, top tiers at 720 to 740	Spring EQ: 640. Homebridge top tier: 720+. Aaron's advertised HELOC programs: 640
Debt-to-income	Roughly 45% to 50% max	Homebridge: about 45%. Spring EQ: 50%
Income	Verified income and employment	Spring EQ: 1 to 2 years of tax returns if self-employed
Occupancy	Primary gets the highest limits	Spring EQ: 80% max on second homes and investment property at 740+
Valuation	AVM on smaller lines, appraisal on larger ones	Spring EQ: full appraisal above $400,000 on a second lien
Mortgage history	Few or no recent late payments	Spring EQ: no 30-day lates in the last 6 months on a primary
Time to close	Varies by lender	Navy Federal: 30 to 40 calendar days from application

How much equity do you need for a HELOC?

Lenders measure equity through combined loan-to-value (CLTV): your first mortgage balance plus the full HELOC line, divided by your home's value. Many lenders cap CLTV at 80% to 90% on a primary residence. At those caps, you need at least 10% to 20% of your home's value left unborrowed after the line is set.

The Federal Reserve's HELOC booklet shows the basic math with a 75% cap. On a home appraised at $100,000, 75% is $75,000. Subtract a $40,000 mortgage balance and the potential line is $35,000.

Public caps sit in a range. Homebridge lists an 80% maximum for primary residences. Spring EQ allows up to 90% for borrowers with a 680 or higher score. Spring EQ's matrix calls this HCLTV, because they count the full line amount, not only what you have drawn.

Here is a worked example using hypothetical numbers: a $600,000 home with a $330,000 first mortgage balance.

Max CLTV	Total debt allowed ($600,000 x cap)	Minus first mortgage	Maximum line
80%	$480,000	$330,000	$150,000
85%	$510,000	$330,000	$180,000
90%	$540,000	$330,000	$210,000

That figure is a ceiling set by equity alone. The Federal Reserve booklet notes that the actual limit also depends on your ability to repay. Program maximums cap it too, such as $500,000 on a Spring EQ second-lien HELOC.

To estimate your own line, multiply a realistic home value by the cap and subtract what you owe. The lender's valuation sets the value used.

What credit score do you need for a HELOC?

Each HELOC program sets its own credit floor. Spring EQ's matrix starts at 640, and the HELOC programs Aaron advertises also start at a 640 credit score. On many lender matrices a higher score allows a higher CLTV, so your score affects how much you can borrow as well as whether you qualify.

Homebridge treats 720 and above as its top tier for maximum borrowing power. Spring EQ's September 2026 matrix ties CLTV directly to score:

Credit score	Primary residence max CLTV	Second home max CLTV	Investment max CLTV
740+	90%	80%	80%
680-739	90%	70%	70%
660-679	80%	Not listed	Not listed
640-659	70%	Not listed	Not listed

The same matrix requires a 740 score for any line of $400,000 or more.

Before you apply, pull your credit reports and fix errors. Paying down revolving balances can move you into a higher tier.

What debt-to-income ratio and income documents do HELOC lenders want?

Debt-to-income (DTI) is your monthly debt payments divided by your gross monthly income. Many HELOC programs cap it around 45% to 50%. Lenders verify the income behind that ratio with documents or electronic records before they approve a line.

The CFPB's DTI example adds a $1,500 mortgage, a $100 auto loan and $400 of other debts for $2,000 a month. Against $6,000 of gross monthly income, that is a 33% DTI. The CFPB notes that different products and lenders set different DTI limits.

Homebridge says most approvals allow DTI up to about 45%, with room above that for strong credit and reserves. Spring EQ's matrix sets a 50% maximum. The Federal Reserve booklet says lenders judge your ability to repay by looking at your income, debts, other financial obligations and credit history.

Income documentation depends on how you earn. Homebridge's approvals are subject to verification of income, employment, occupancy, title, credit and home value. Spring EQ asks self-employed borrowers with 5 or more years in business for the most recent year of personal and business tax returns plus IRS transcripts. Self-employed borrowers with less than 5 years provide 2 years. For salaried borrowers, the matrix points to Fannie Mae's Selling Guide rather than listing its own document rules.

Gather recent pay stubs, W-2s and tax returns before you apply. If you own a business, have both personal and business returns ready.

Can you get a HELOC on a second home or investment property?

Some lenders offer HELOCs on second homes and investment properties, but with lower CLTV caps and stricter rules than a primary residence. Many programs also exclude certain property types entirely, whatever the occupancy.

Homebridge lists primary residences, second homes and investment properties, and says investment properties may have stricter guidelines. Its eligible property types are single-family homes, condos and planned unit developments.

Spring EQ's matrix shows the gap in numbers. At a 740+ score, a primary residence can reach 90% CLTV, while a second home or investment property tops out at 80%. At 680-739, the non-primary cap drops to 70%. The matrix also sets these rules:

• At least one borrower must have been on title for 6 months before applying on an investment property.
• Second homes and investment properties need zero 30-day mortgage lates in the last 24 months.
• 2-4 unit investment properties and multi-unit second homes are ineligible.
• Co-ops, condotels, mobile and manufactured homes, and timeshares are ineligible for any occupancy.

If the property is a rental, expect a lower line and a full appraisal. Confirm the property type is eligible before you pay any fees.

Do you need an appraisal for a HELOC, and how long does approval take?

Many lenders accept an automated valuation model (AVM) on smaller lines for owner-occupied homes and require a full appraisal on larger lines, higher CLTVs or investment properties. Approval and closing time varies by lender. Navy Federal currently estimates 30 to 40 calendar days from application.

Spring EQ's valuation rules for a second-lien HELOC show how the thresholds work:

Line amount	Primary or second home	Investment or 2-4 unit
Under $250,000	AVM allowed	AVM allowed
$250,000 to $400,000	AVM allowed only at 80% HCLTV or less	Full appraisal
Over $400,000	Full appraisal (or eligible prior or piggyback report)	Full appraisal

An AVM there must be dated within 60 days of the note date, meet a confidence threshold and come with a property condition report. A full appraisal must rate the home at least Q5 for quality and C5 for condition, with repair costs no higher than the greater of $2,000 or 2% of value.

Timing depends on how fast you return documents and whether the file needs an appraisal. Send income documents and your current mortgage statement at the start so underwriting is not waiting on you.

What can stop a HELOC approval?

The most common stoppers are too little equity once the value comes in, a score below the program's tier and a DTI above the cap. Recent mortgage late payments, a recent listing for sale, an ineligible property or title setup, and recent major credit events can also make a file ineligible.

A low valuation shrinks the line directly. In the hypothetical above, if the home values at $560,000 instead of $600,000, an 80% cap allows $448,000 of total debt. After the $330,000 first mortgage, the maximum line falls from $150,000 to $118,000.

Spring EQ's matrix lists other stoppers in specific terms:

• A primary residence can have one 30-day mortgage late in months 7 to 24, and none in the last 6 months.
• A property listed for sale in the 120 days before the application date is ineligible.
• Vesting in an LLC, life estates, irrevocable trusts and land contracts are ineligible ownership types.
• Recent major credit events can disqualify an application.

Check each of these against your file before you apply. If one of them is a problem, you want to know before you pay an application fee.
