The Quick Read: On a primary residence, a home equity line of credit (HELOC) usually comes down to three tests: a credit score above the program floor, a debt-to-income ratio (DTI) under the cap, and enough equity left after the first mortgage. There is no minimum salary.
- Credit: The floor across Lendmire’s wholesale partners is 600. The strongest leverage tiers start at 700 and 720.
- Income: Lenders check the ratio of your debts to your income, not a dollar amount. The cap is 50%, and it drops to 45% for scores from 600 to 679.
- Equity: The line is sized by combined loan-to-value (CLTV). On a primary residence, the top ceiling is 90%, and only at a 720 score.
- Occupancy: Primary-home terms are the most generous. Second homes and investment properties face higher credit floors and lower leverage.
Most people searching this are not just curious. So this walkthrough covers how lenders judge the home you live in, where the rules bend, and how the decision looks next to a DSCR loan. A DSCR loan is an investor loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
One note up front. Lendmire is a broker. It places these lines through select wholesale partners and does not lend. Every figure below is subject to lender guidelines and full file review, and none is a commitment to lend.
What Do Lenders Actually Check on a Primary-Home HELOC?
Lenders check four things: your credit profile, your income against your debts, your equity, and the property and title itself. A HELOC sits behind or beside your main mortgage, so the lender is more careful than it would be on a first loan. The home is the collateral either way.
Here is how the deal works, step by step:
1. Value. The lender estimates what the home is worth today. For lines at or below $500,000, that usually means an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation. You can also ask for a full appraisal.
2. Credit. The lender pulls a credit report. The score decides whether you qualify and how much of your equity you can reach.
3. Income and DTI. The lender verifies income, adds up your monthly debts, and measures the ratio.
4. Property and title. Eligible property types and ownership rules get checked.
5. Closing and draw. The line opens and you draw funds.
Each step can cap the line on its own. Strong equity does not rescue a score below the floor. A great score does not rescue a DTI over the limit. The strongest files clear all of them.
Credit Score: Where the Floor Is and What It Buys
The program floor on a primary-residence HELOC is 600. A higher score moves you into higher CLTV tiers and larger line sizes. Across the network, the score controls leverage more than it controls yes-or-no approval.
Here are the maximum CLTV tiers on a primary residence:
| Credit score | Max CLTV (primary residence) | Line size up to |
|---|---|---|
| 720+ | 90% | $500,000 |
| 720+ | 75% | $750,000 |
| 700+ | 85% | $500,000 |
| 680+ and 660+ | 85% | $500,000 |
| 640+ | 80% | $500,000 |
| 620+ | 70% | $400,000 |
| 600+ | 60% | $400,000 |
Read the 720 row carefully. At 720 you pick a tradeoff: 90% CLTV on a line up to $500,000, or a larger line up to $750,000 at a reduced 75%. The 90% figure exists only at a 720 score.
A line above $500,000 is primary-residence only. It needs a 700 score or better (720 on the longer-runway program, described below). It caps at 75% CLTV and requires a full appraisal.
A few rules sit behind the score:
- Which score. The lender uses a single-bureau score model keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed.
- Tradelines and housing history. The longer-runway program wants two tradelines seasoned 12 months or one seasoned 24. It also wants a clean housing history, 0x30x6 and 1x30x12 at 640 and above, and 0x30x12 from 600 to 639. Late-payment patterns matter, not just the number.
- Past credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits: one wholesale program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines that history entirely, regardless of age.
- Business bank accounts. Using business accounts for the deposit analysis needs a 680 minimum. A 640 borrower can qualify for the line but cannot use them.
Markets outside this network report different minimums. Many lender pages say 620 is the usual floor, and others say 680. That spread is the point: no federal rule sets the number, so it is lender policy.
Income Requirements: A Ratio, Not a Salary
There is no minimum income for a HELOC. Lenders measure DTI, which is your total monthly debt payments divided by your gross monthly income. The cap on this network is 50%, and 45% for credit profiles from 600 to 679. A ratio above 45% needs a 680 score at minimum.
That is the myth to drop. A borrower earning less can qualify with low debts. A high earner can fail with heavy debts.
One detail changes the result. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. So a line you intend to barely touch is still counted at full size.
Run the numbers as percentages. Say a borrower sits at 38% DTI before the line. The interest-only payment on the full limit adds the equivalent of 8 points of income. The new ratio is 46%. That clears a 680-plus borrower. It fails a 660 borrower, whose cap is 45%. Same income, same line, different answer.
Documentation follows the income type:
- Employees: pay stubs and W-2s.
- Self-employed: traditional personal-income documentation, or documented income under the applicable program, subject to lender guidelines.
- Variable income (bonus, commission): typically a multi-year history.
- Retirement or fixed income: award letters or statements.
Bank statements from a business account can support the file, but that 680 floor applies.
How Much Equity Counts? CLTV on Your Home
Equity is your home’s current value minus what you owe, and it is judged on today’s value, not what you paid, as TheStreet’s explainer on HELOC requirements notes. The line is then sized by CLTV, which adds the new line to your existing mortgage balance and divides by value.
Skip the dollars and think in shares of value. Say your first mortgage equals 50% of the home’s value. At an 85% CLTV cap, the line can use up to 35% of value. At a 70% cap, only 20%. Your credit tier decides which cap you get.
Two other limits can bite first:
- Line size. Lines run from $25,000 to $750,000. The tier table above shows the size limits by score.
- Draw at closing. At least 75% of the line is drawn at closing. This is not a pure standby line.
Then comes the structure. The line is a standalone line in first or second lien position. Primary residences and second homes have two draw structures: a 3-year interest-only draw followed by a 17-year repayment, or a 5-year interest-only draw followed by a 25-year repayment. Pricing floats during both the draw and the repayment period. It never converts to fixed. The longer-runway program uses the 5-year draw. The higher-leverage program is the one that reaches 90% CLTV and allows combined exposure up to $2,000,000.
A payment jump when the draw ends is the real risk with any line like this. Plan for it before you borrow.
Key Terms Defined
HELOC: A revolving line of credit secured by the equity in your home. You borrow against it as needed, up to a limit.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value.
DTI (debt-to-income): Monthly debt payments divided by gross monthly income.
Draw period: The early stretch when you can borrow and pay interest only.
Repayment period: The later stretch when the balance fully amortizes and you can no longer draw.
DSCR (debt service coverage ratio): A rental’s income divided by its monthly payment, covering principal, interest, taxes, insurance, and any HOA dues.
Seasoning: The waiting period a lender wants after an event, such as a bankruptcy or a purchase.
Where Federal Rules Fit
No federal rule sets a minimum score or income for a HELOC. The ability-to-repay rule that governs standard closed-end mortgages excludes HELOCs from its scope, so underwriting standards are lender policy. That does not mean lenders ignore repayment ability. They still underwrite credit and income, as the sections above show.
The government’s plain-language definition is also worth knowing. The CFPB’s explanation of a HELOC describes an open-end line you can draw on repeatedly during a draw period, with a 10-year draw as one example. It also warns that if you fall behind, you could lose the home. That point matters more when the money buys a rental.
Edge Cases: Where the General Rule Breaks
The primary-home rules above bend in a handful of named situations.
Second homes and investment properties. The credit floor rises to 640 on a second home and 700 on an investment property. An investment line tops out at 70% CLTV. Investment lines run the 5-year draw and 25-year repayment structure only. Lines above $500,000 are not available on them.
Converting your home to a rental. HELOC agreements can prohibit renting the home out. The CFPB’s HELOC booklet warns that this may be a violation of the terms, so read yours before moving out.
Title held in an LLC. Only the individual borrower or a revocable living trust can hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead.
Texas primary residences. These are homesteads. They cap at 80% combined loan-to-value, so the higher tiers in the table never apply.
Ineligible property. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible on either program. Eligible types include single-family, 2-4 units (a 640 minimum on the longer-runway program), PUD, townhome, and condominium, including non-warrantable. Modular factory-built homes are eligible on the longer-runway program only.
Exposure and portfolio size. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. Someone owning more than 15 financed properties is not eligible.
Sub-640 profiles. On the longer-runway program, these are limited to single-family residences with a clean 12-month housing history. Because second homes floor at 640 and investment at 700, this restriction reaches primary residences only.
Availability. HELOCs are offered only in Lendmire’s 16 full-service states. That is narrower than its DSCR footprint of 41 markets, including Washington, D.C. Some states also layer on their own CLTV caps or rules about homes recently listed for sale.
HELOC or DSCR Loan? What the Investor Decision Looks Like
Use the two tools for different jobs. A HELOC is sized by your credit, income, and the equity in your own home. A DSCR loan is sized by the rental’s income. The two can run in sequence: a line on your residence funds the down payment, then a DSCR loan buys the rental.
Know what the HELOC does to the rest of your file. It adds a payment to your DTI. It puts a lien on the home you live in. It also ties the two properties together until the line is repaid or refinanced. Tax treatment varies; consult a qualified professional before relying on any deduction.
Now the DSCR side. On a purchase, most files land at 75% to 80% LTV, with select high-leverage programs reaching 85% at roughly a 700 score or better. A cash-out refinance tops out around 75% LTV, and about 6 months of seasoning is the common expectation. A 1.00 coverage ratio is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Most programs want around a 660 score, and a 620 floor exists in parts of the network. DSCR compares rent to the full monthly payment only. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation.
Here is where the strategies differ. A HELOC on your home needs a personal income test. A DSCR loan puts the rental’s income first. A borrower with high DTI but a strong rental can find DSCR the cleaner fit. A borrower with great income and a weak rental may find the opposite.
The stronger play for many investors is to fund the down payment from the line, then confirm the rental itself clears coverage. Others will argue the reverse: skip the line, bring cash, and keep the home free of liens. The right answer depends on how much cushion you have if the rental sits empty. For more on how rental-backed loans work, see Lendmire’s complete DSCR loans guide.
Across the wholesale partners Lendmire works with, the files that stall are rarely about the score. They stall on DTI, when the full-limit payment gets counted and surprises the borrower. Run your ratio at the maximum draw before you apply, not at the amount you expect to use.
Not Qualifying Yet? Fix These in Order
Pull the levers in this order:
1. DTI first. Paying off a small installment loan can move the ratio faster than anything else. It also helps the most when you sit just over 45%.
2. Score second. Cutting card balances and keeping every payment on time can lift the number. This takes the longest, so start early.
3. Equity third. You can only add it by paying down the mortgage or by home value rising.
4. Property and title last. Move the home into your own name or a revocable living trust if it sits elsewhere.
Shopping around helps too. Wholesale partners set different floors and tradeline rules. Your file might clear one program and miss another.
Frequently Asked Questions
What credit score do I need for a HELOC on my primary home?
The program floor is 600. At that level you can reach 60% CLTV on lines up to $400,000. At 720 the ceiling reaches 90% CLTV on lines up to $500,000. Exact eligibility depends on lender guidelines, the full credit file, and the property.
Is there a minimum income for a HELOC?
No. Lenders measure DTI, which is debts against income. The cap is 50%, or 45% if your score is 600 to 679. Documentation requirements follow your income type, such as pay stubs, W-2s, or traditional personal-income documentation.
Can I use a HELOC on my home to buy a rental property?
Many investors do exactly that, using the line for the down payment. Check the agreement for any restriction on renting out the home. Remember that the line adds to your DTI and puts a lien on your primary residence. A DSCR loan can then finance the rental itself.
Can an LLC hold title on a HELOC property?
No. Title must sit with the individual borrower or a revocable living trust. A home already deeded to an LLC needs a vesting change first. Alternatively, a DSCR cash-out refinance may fit the situation better.
Do I have to use all of the line at closing?
At least 75% of the line is drawn at closing. After that, subsequent draws have a $1,000 minimum on the longer-runway program, and Texas sets it at $4,000. Pricing floats through the draw and repayment periods and never converts to fixed.
