The Quick Read: A home equity line of credit sits behind your first mortgage as a separate loan, so nothing about the existing mortgage changes, and approval depends on credit, remaining equity, debt-to-income, property type, and how the property is titled, with an investment property capped at 70% combined leverage. Lendmire, a DSCR-focused mortgage broker, arranges these lines through select wholesale partners in 16 full-service states. That is narrower than its 41-market DSCR footprint, which includes Washington, D.C. Every figure below is subject to lender guidelines and full file review.
- The line is a second loan, or a first loan on a property with no mortgage, so no refinance is needed.
- On an investment property the network ceiling is 70% combined loan-to-value, with a 700 minimum credit score and a $500,000 maximum line.
- Primary homes and second homes can reach 90% combined leverage, but only at a 720 credit profile or better.
- Title matters. LLC-owned property cannot hold these lines.
- Equity alone does not qualify you. Debt-to-income and credit must also fit.
Key Terms Defined
Combined loan-to-value (CLTV): every loan secured by the property, added together, divided by the property’s value.
Second lien: a loan that sits behind the first mortgage in repayment priority, so the first mortgage stays untouched.
Draw period: the stretch when you can borrow from the line and pay interest only.
Repayment period: the stretch after the draw ends, when you can no longer borrow and the balance amortizes.
Vesting: how the deed names the owner, such as an individual, a revocable trust, or an LLC.
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.
Does a HELOC Require Refinancing the First Mortgage?
No. A HELOC is its own loan with its own lien. Your first mortgage keeps its balance, its terms, and its lender.
The FTC describes a HELOC as a revolving line secured by the property. You pay interest only on what you draw, not on the full limit. Many lines include a draw period followed by a repayment period in which you can’t borrow more.
Two cases still need a refinance. One is a property already deeded to an LLC, which these lines can’t secure. The other is a borrower who wants to change the first mortgage’s terms or remove a borrower from it. A line can’t do either of those jobs.
How Underwriting Treats a HELOC, Step by Step
Underwriting runs in a fixed order: collateral, equity after the line, borrower capacity, then property and title review. Each step can end the file, so it helps to check them in sequence before you apply.
1. Pick the collateral. The line secures either a rental you own or your primary home. You can’t open one on a property you haven’t bought yet. ConsumerAffairs notes that you can draw on an existing line to fund another purchase.
2. Run the equity test. The lender adds the first mortgage and the requested line, divides by the property’s value, and compares the result to a leverage ceiling. Room for the line equals the ceiling minus the first mortgage, both measured as a share of value.
3. Test the borrower. Across the lenders in Lendmire’s wholesale network, debt-to-income tops out at 50%. It tightens to 45% for credit profiles between 600 and 679, and any ratio above 45% needs at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. The existing first mortgage counts in that ratio.
4. Pull credit. The score model is a single bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores.
5. Value the property. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal in any case. Every line above $500,000 requires one.
6. Check title and property type. The deed must name an individual or a revocable living trust. The property must be on the eligible list.
7. Review the first mortgage documents. If the first loan is a DSCR loan or another investor product, its documents may limit a second lien. Read them before applying.
Requirements at a Glance
Network ceilings depend on occupancy, and the top tier requires a 720 credit profile. The table shows each occupancy’s floor and ceiling, which differ sharply, so find your own row before reading anything else.
| Occupancy | Minimum score | Ceiling CLTV | Maximum line |
|---|---|---|---|
| Investment property | 700 | 70% | $500,000 |
| Second home | 640 | 90% at 720+ | $500,000 |
| Primary residence | 600 | 90% at 720+ ($500,000 line) | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
Primary residences also have a mid-tier path: at a 700 or 720 score, a larger line up to $750,000 is available at a 75% CLTV cap. Lower scores step the ceiling down, with smaller maximum lines at those tiers. Second homes also step down as scores fall, with the highest ceiling reserved for stronger scores.
One credit rule applies to any line above $500,000. It is primary-residence only and needs a 700 score or better, rising to 720 on the 5-year-draw structure described below. It also caps at 75% CLTV and requires a full appraisal.
Other requirements:
- Line size: $25,000 to $750,000 in most cases.
- Draw at closing: at least 75% of the line is drawn at closing.
- Later draws: the minimum is typically $1,000 after closing.
- Tradelines and history: standards vary by program. One structure asks for two tradelines seasoned 12 months, or one seasoned 24. It also asks for a clean housing history across all financed properties.
- Bankruptcy: four years of seasoning from discharge or dismissal.
- Eligible property: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos.
- Not offered: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property.
A Worked Combined-Leverage Example
Run the numbers on an investor with a rental, a 700 score, and a first mortgage equal to 50% of the property’s value. The network’s investment ceiling is 70% CLTV. The room left for a line is therefore 20% of the property’s value, as long as that stays under the $500,000 maximum.
Now change one input. If the first mortgage is 65% of value, only 5% of value remains. The line may then fall short of the $25,000 minimum on a modestly priced property. That is a common reason a good-credit investor still gets a thin result.
Credit doesn’t move this ceiling. On an investment property, a 720 score reaches the same 70% as a 700 score. Stronger credit helps with eligibility and with the 45%-versus-50% debt-to-income test, but it doesn’t buy more leverage.
Primary homes behave differently. A homeowner at 720 with a first mortgage at 60% of value has room for a line up to 30% of value, which would take combined leverage to the 90% tier on a line of $500,000 or less. A homeowner at 640 gets the 80% tier instead, so the same first mortgage leaves 20% of value.
Structures and Variations That Exist
The core variations are lien position, draw structure, and how the borrower qualifies.
Lien position. The line can be a second lien behind an existing mortgage or a first lien on a property with no mortgage. A paid-off rental can therefore carry a line in first position, which keeps a no-mortgage property from needing a full cash-out refinance.
Draw structure. On primary residences and second homes, two structures exist:
- a 3-year interest-only draw followed by a 17-year fully amortizing repayment
- a 5-year interest-only draw followed by a 25-year fully amortizing repayment, called the 5-year-draw structure here
Investment-property lines use the 5-year draw and 25-year repayment only. Pricing floats through both periods and never converts to a fixed payment. A payment that was small during the draw can step up sharply when repayment begins.
Borrower qualification. The lines described here qualify the borrower personally, using credit and debt-to-income. A rent-qualified line, where the property’s rent against a stress payment replaces the personal ratio, circulates in the market under the label DSCR HELOC. That label is not a standardized product, and terms vary program by program. Investors who own several financed properties or hold title in an entity usually find the personal-ratio path restrictive. They often get further with a DSCR cash-out refinance, covered in Lendmire’s complete DSCR loans guide.
For more on the rent-qualified idea, see Lendmire’s explainer DSCR HELOC Requirements Without Refinancing Your First Mortgage.
HELOC, Home Equity Loan, or Cash-Out Refinance?
Each option answers a different need. A line suits staged, uncertain costs. A closed-end second suits a single known expense. A cash-out refinance suits an investor willing to replace the first mortgage entirely.
| Factor | HELOC | Home equity loan | DSCR cash-out refinance |
|---|---|---|---|
| First mortgage | Stays | Stays | Replaced |
| Funds | Draw as needed | One lump sum | One lump sum |
| Reviewed on | Personal credit, DTI | Personal credit, DTI | Rent coverage, credit |
| Entity title | Not allowed | Varies by lender | Often allowed |
| Typical leverage | 70% on investment | Varies by lender | Up to about 75% |
The cash-out column reflects select programs in the network. Most files land around a 75% LTV ceiling on a standard rental, with about six months of seasoning as the common expectation. Short-term-rental collateral typically tops out near 70%. Coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Most programs want a score near 660, and 700 or more opens the strongest tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).
One caution applies here. A DSCR ratio compares rent to the full monthly obligation only. Clearing it does not mean the property cash-flows. Repairs, vacancy, management, and capital costs sit outside the calculation.
Where the General Rule Breaks
The general rule is that a HELOC needs equity, credit, and a fitting ratio. These named situations bend it.
LLC title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Only an individual or an inter vivos revocable living trust can. A property already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead. Moving a property out of an LLC can have its own consequences, so review the loan documents and the property’s insurance and legal setup first. Treat any entity-held rental as a DSCR cash-out candidate by default, subject to program terms.
Portfolio size. A borrower can hold only three lines in total. An investor with more than 15 financed properties is not eligible. Large portfolios are where DSCR cash-out becomes the practical route.
Credit under 640. Profiles below 640 are limited to single-family residences with a clean 12-month housing history on the 5-year-draw structure. Because second homes floor at 640 and investment lines at 700, this restriction reaches primary residences only.
Credit history events. Bankruptcy needs four years of seasoning on every file. A foreclosure, deed-in-lieu, pre-foreclosure, or short sale splits the field. One program seasons foreclosure at seven years, while another seasons it at four and a third declines the history entirely, regardless of age.
Occupancy labels. A property rented short-term can be classified as a second home rather than an investment property. That shifts the leverage table, since second homes sit at a higher tier than investment property. The classification follows the lender’s review of how the property is used, so confirm it before assuming either row.
Property type. Manufactured homes, log homes, and barndominiums fall outside these programs and outside the network’s DSCR programs. Don’t plan around them.
Rescission rights. The federal three-business-day cancellation right applies to credit secured by a principal dwelling. A second home or rental isn’t one. A line on your own home carries that cooling-off period, as the FTC explains. A line on a rental does not.
Collateral choice. A line secured by a rental keeps your primary residence out of the lien. A line secured by your home does the opposite, and if the rental underperforms, your home is the collateral. That tradeoff is as much a risk decision as a financing one.
Keep the Mortgage or Refinance?
Keep the first mortgage if its terms are favorable and the equity you need fits inside the line’s leverage ceiling. That is the main reason to choose a line instead of a refinance. The first loan is untouched, and you pay interest only on what you draw.
Refinance if the equity you need exceeds the ceiling, the property sits in an entity, or you want fixed terms instead of a floating payment. A DSCR cash-out refinance reaches higher leverage on a standard rental than a personal investment line does. It also is reviewed on the property’s rent coverage, subject to lender guidelines, instead of your personal ratio.
The use of funds matters too. A line fits staged costs such as repairs between tenants or renovation draws. A single fixed need, such as a down payment on the next rental, may fit a closed-end second better. Tax treatment varies; consult a qualified professional.
If your equity is thin, no program fixes that. Pay down the first mortgage, wait for the property to appreciate, or lower the amount you request. Reaching for a bigger line on weak numbers is the wrong response.
The Application, Step by Step
1. Gather balances. Collect the first mortgage balance, a realistic property value, and a recent credit report.
2. Compute combined leverage. Divide the first mortgage plus your target line by the value. Compare it to the ceiling for your occupancy.
3. Confirm title. Check that the deed names you or your revocable trust.
4. Read the first mortgage terms. Look for second-lien restrictions, especially on investor first loans.
5. Submit the application. Provide credit, income, and property details. The lender decides whether an automated valuation or a full appraisal applies.
6. Review the line terms. Check the draw and repayment structure, the 75% closing draw, and how payments change after the draw.
7. Draw and manage. After closing, draws start at about $1,000 minimums, subject to the program.
What Can Go Wrong
Payments float. The payment can change even when your borrowing doesn’t, and it can step up when repayment starts. Combined leverage also leaves less cushion if values drop. A line on a rental puts that rental at risk. A line on your home puts your home at risk.
Keep the line sized to the plan. A line used to bridge a renovation with a clear exit is a different animal from a line used to cover recurring shortfalls.
Frequently Asked Questions
Can I have a mortgage and a HELOC at the same time?
Yes. The line is a second lien behind the first mortgage, and both loans stay active. Lenders add the first mortgage payment to your debt-to-income test, and the first loan’s documents should allow a second lien. On a property with no mortgage, the line can sit in first position.
How much equity do I need?
It depends on occupancy. On an investment property the network ceiling is 70% combined leverage, so the first mortgage plus the line can’t exceed 70% of value. Primary homes and second homes can reach 90% at a 720 profile or better. Lower scores step the ceiling down, and lines above $500,000 are capped at 75% on primary residences.
Is an appraisal required?
Not always. Lines at or below $500,000 ordinarily run an automated valuation, though a higher CLTV may need a second one, and you can ask for a full appraisal. Every line above $500,000 requires a full appraisal.
Can an LLC hold a HELOC?
No, not on these lines. Title must sit with an individual or a revocable living trust. An LLC-owned rental usually points toward a DSCR cash-out refinance, subject to program terms, or toward a vesting change before applying.
What credit score do I need?
It depends on occupancy. Investment lines start at 700, second homes at 640, and primary residences at 600. Higher scores raise the leverage tier on primary homes and second homes. On investment property, 720 gets the same ceiling as 700.
