The Quick Read: The right provider is the one whose program fits your property, equity, and credit profile, not the one on a ranked list. A home equity line of credit (HELOC) on your primary residence can supply cash for either goal. Lendmire is a mortgage broker, so it shops select wholesale lenders and matches your file to a program.
- On a primary-residence line, combined loan-to-value (CLTV) reaches 90% only at a 720 or better credit profile. A line above $500,000 caps at 75% CLTV.
- On a second-home line, the ceiling steps from 75% at a 640 credit profile up to 90% CLTV, and 90% requires 720 or better.
- On an investment-property line, the ceiling is 70% CLTV. No credit tier goes higher.
- Lines run $25,000 to $750,000, but anything above $500,000 is primary-residence only.
- A HELOC is underwritten on your personal income, credit, and equity, never on a business’s revenue or a rental’s income.
A ranked “top five” would mislead you here. The lenders that write these lines differ on property type, occupancy, credit floors, and what the funds can be used for. A broker that sees several programs can sort those differences for you.
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.
What a HELOC Actually Is
A HELOC is a revolving line of credit secured by your home. You draw what you need, repay it, and draw again. During the draw period, payments are typically interest-only. After that, a repayment period begins and the balance amortizes.
The Consumer Financial Protection Bureau describes it as an open-end line that lets you borrow repeatedly against your equity. It also says the repayment period often runs ten or 20 years. If you cannot repay as agreed, you could lose the home.
If you already have a mortgage, the HELOC sits behind it as a second payment. On the lender’s side, a line can also sit in first-lien position when there is no mortgage. Either way, your home backs the money you spend on the business or the down payment.
Key Terms Defined
HELOC: a revolving credit line secured by your home, with a draw period followed by a repayment period.
CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the home’s value.
Draw period: the stretch when you can borrow from the line, usually with interest-only payments.
Repayment period: the stretch after the draw period when you repay principal and interest.
DSCR (debt service coverage ratio): a rental’s monthly rent divided by its monthly mortgage obligation.
PITIA: principal, interest, taxes, insurance, and any association dues, which together make up that obligation.
Vesting: the legal name that holds title to the property, such as an individual or a trust.
How the Underwriting Works, Step by Step
Underwriting a HELOC means checking whether you, personally, can carry the debt, and whether the home has enough equity behind it. Business plans and rental projections do not enter the HELOC decision. Here is the sequence.
Step 1: Pick the collateral. The usual choice is your primary residence. A line on an existing rental is possible, but investment-property lines carry tighter terms on this network. They cap at 70% CLTV and start at a 700 credit profile.
Step 2: Work out usable equity. The lender takes a percentage of the home’s value and subtracts what you owe. The CFPB’s HELOC booklet walks through that arithmetic with an illustrative percentage.
Picture a primary residence with a first mortgage at 50% of its value. If the lender’s ceiling for your profile is 80% CLTV, the line can reach roughly 30% of the home’s value. At the 90% primary-residence ceiling, which needs a 720 or better profile, the cushion is wider. Credit tier, line size, and valuation can all pull the final number below the ceiling.
Step 3: Qualify on personal numbers. Debt-to-income (DTI) is capped at 50%, but profiles from 600 to 679 face a 45% cap. Going above 45% requires a 680 minimum score. The lender reviews your file on the interest-only payment calculated on the maximum draw, not the amount you plan to use. A line you intend to draw lightly is still tested as if it were fully drawn.
Step 4: Valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you can request a full appraisal in any case. Every line above $500,000 requires one.
Step 5: Close and draw. The network programs require at least 75% of the line to be drawn at closing. Pricing floats across both the draw and repayment periods and never converts to fixed. That matters if you wanted a standby line you would barely touch.
Step 6: Move the money and document it. The funds land in your account. The lender on the second home or the business purchase will want a paper trail showing where the cash came from. Because HELOC proceeds are borrowed funds, confirm with that lender how it treats them for the down payment and for reserves.
Step 7: Repay and reuse. As you repay, available credit replenishes. The line can fund a later deal, though the draw period and any minimum balances shape how that works.
Two Draw Structures, and Where They Differ
The wholesale lenders behind these lines run two structures on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year repayment. Investment-property lines use the 5-year draw and 25-year repayment structure only. Some states shorten both structures.
Pricing floats on each, so any figure you are quoted comes with that program’s own draw and repayment schedule. Always ask which structure a quote assumes before comparing two offers.
The network has two wholesale programs, and they differ on details. One is a higher-leverage program. The other is a longer-runway program built around the 5-year draw. The longer-runway program asks for two tradelines seasoned 12 months or one seasoned 24, with a clean housing history. Where the two differ, each figure applies only within its own program.
Here is how the second-home line tiers look for lines up to $500,000, subject to lender guidelines and full file review.
| Credit profile | Max CLTV, second home |
|---|---|
| 720+ | 90% |
| 700+ | 85% |
| 680+ | 85% |
| 660+ | 80% |
| 640+ | 75% |
The minimum credit profile for a second-home line is 640. These tiers apply to second homes only, so an investment-property line sits below every one of them.
What Separates One Line From Another
Most “provider” comparisons rank company names. A better question is which features matter for your deal. These are the ones that decide the outcome.
| Factor | Why it matters to you |
|---|---|
| Occupancy allowed | Primary, second home, and investment lines differ |
| Max CLTV for your credit | Sets how much equity you can reach |
| Draw and repayment structure | Changes the payment after the draw ends |
| Use of proceeds | Some agreements limit business use |
| Vesting and title rules | Individuals and revocable trusts only |
| Property eligibility | Condos, 2-4 units, and PUDs vary |
Use of proceeds deserves a closer look for the business-purchase half of your goal. Achieve notes that some lenders prohibit business use or certain types of business. Read the line agreement before you draw, not after.
A single bank offers one set of guidelines. A broker can compare several wholesale programs and match your scenario to the one that fits.
Using the Line for a Second Home or Rental Down Payment
A HELOC on your primary residence can cover the down payment on another property. The Nasdaq/SmartAsset explainer says lenders check your income and existing debts before approving the line. It also says borrowing the down payment lets you keep cash on hand for other uses.
The second loan works differently. If the new property is a rental, a DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Here is the structure that often works. The HELOC supplies the down payment. The DSCR loan finances the rental. The rent has to cover the new loan, and you have to cover the HELOC payment from your own income. Those are two separate tests.
Across the wholesale network, DSCR purchase loans most often land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700 or better score. A larger down payment lowers the new loan’s payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. A path with no coverage ratio also exists through select lenders, generally for borrowers who already own a primary residence. You likely do, since you are borrowing against one.
Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside that calculation. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA. Conservative files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.
Think of the second-home case differently from the rental case. A vacation home you use yourself is not a rental, so the DSCR route generally does not apply to it. A second-home purchase is better served by a conventional purchase mortgage for the home itself, with the HELOC supplying the down payment. The purchase lender will weigh your whole financial picture.
For rental purchases, Lendmire’s complete DSCR loans guide walks through the property-side numbers. DSCR loans are available across 41 markets, including Washington, D.C., while the HELOC placements described here are limited to 16 full-service states. That footprint is narrower, so check availability for your state early.
Using the Line for a Business Purchase
A HELOC can supply cash toward buying a business, but it rarely covers the whole price. BizBuySell says buyers often combine home equity with other financing. It also warns that if the business fails, the home is at risk of foreclosure.
The business’s revenue does not qualify you for the line. Your personal credit, DTI, and home equity do. That helps a buyer with no business credit history, but it also means every dollar of risk lands on your home.
A few practical points follow from that.
- The seller, an SBA-style lender, or an investor may supply the rest of the price. The HELOC fills the equity gap.
- You are tested on the interest-only payment calculated on the maximum draw. That figure counts against your DTI before the business earns anything.
- With at least 75% of the line drawn at closing, you carry the cost of most of it from day one. A purchase with a delayed start date makes that cost heavier.
- Lenders may ask about use of funds. A line agreement that restricts business use can stop the draw.
Where the General Rule Breaks
The basic plan is a HELOC on your primary home, cash in hand, then a purchase. Several edge cases change it.
Your property is held by an LLC. HELOC title must sit with the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan, which can close in an entity name, subject to lender program eligibility. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
You plan to sell the home. Some line agreements restrict renting that home out. If a move is on the horizon, a HELOC may be the wrong tool.
Your credit profile is thin or damaged. The program floor is 600. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On primary residences and second homes, one program seasons a foreclosure at 7 years and a deed-in-lieu or short sale at 4, while the other declines that history regardless of age. Investment files follow the 7-and-4-year path.
The property type is off the list. Neither HELOC program accepts manufactured homes, co-ops, condotels, log homes, or commercial, mixed-use, or agricultural zoning. DSCR loans on this network do not cover manufactured homes (single- and double-wide), log homes, or barndominiums either. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Modular factory-built homes work on the longer-runway program only.
You already hold a lot of debt on real estate. 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. Owning more than 15 financed properties makes you ineligible.
You want a bigger line. Lines above $500,000 are primary-residence only. They cap at 75% CLTV and require a full appraisal. The credit requirement is 700 or better, or 720 on the longer-runway program.
Your home is listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in some states. Some states also cap CLTV by credit profile or apply extra waiting rules to primary homes. These state differences are real, so ask before you plan around a number.
Stacked Payments: The Part People Underestimate
A down payment funded by a HELOC means three obligations at once: your first mortgage, the HELOC, and the new loan. The HELOC payment floats, while a fixed DSCR payment holds steady. Your home backs the line, so a missed payment puts your primary residence at risk.
NerdWallet cautions against mortgaging your home for risky ventures such as starting a business. That caution applies with equal force to a leveraged rental purchase. Ask whether your income can carry the HELOC if the rental sits vacant for a stretch.
When the draw period ends, the payment changes. The 3-year structure moves into a 17-year repayment, and the 5-year structure into a 25-year one. Plan for the payment after the interest-only years, not only the one you see on day one.
What the Decision Looks Like in Practice
Start with the lower-stakes questions first. Do you have the equity, and does your credit profile reach the CLTV you need? If your first mortgage is already high relative to the home’s value, the line may be too small to matter.
Next, match the use to the product. A rental purchase pairs with a DSCR loan, and the HELOC is only the down payment. A business purchase pairs with whatever financing the seller or a business lender provides, and the HELOC fills the equity gap. A second home you will live in is a different loan altogether.
If you already hold a rental with built-up equity, a DSCR cash-out refinance can be an alternative to a HELOC on your home. Lendmire’s piece Cash-Out Refinance Options to Fund a Business Purchase and a Second Home Down Payment covers that route. Cash-out on a standard rental typically tops out around 75% LTV. Short-term-rental collateral caps at 70%. Cash-out also commonly expects about 6 months of seasoning.
One more comparison matters. The same HELOC logic applies when parents fund a child’s purchase, which Lendmire covers in its article Top HELOC Providers to Gift a Child a First-Home Down Payment. The mechanics are close, but the gift rules on the receiving side are not.

Frequently Asked Questions
Can a HELOC cover the whole down payment on a rental?
It can cover the down payment if your equity, credit, and DTI support a line that size. Most DSCR purchases need 20% to 25% down, and select high-leverage programs go to 15% down with a 700 or better score. The HELOC is borrowed money, so the DSCR lender decides how it treats those funds for the down payment and reserves. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Does the business I am buying help me qualify?
No. A HELOC is reviewed on your personal credit, income, and home equity, not on the business’s revenue. That helps a newer owner without business credit, but it also puts your home behind the debt. A DSCR loan is separate and applies only to rental real estate.
What is the most I can borrow on a second home or an investment property?
On a second home, the ceiling reaches 90% CLTV at a 720 or better profile, up to a $500,000 line. On an investment property, the ceiling is 70% CLTV, and the line caps at $500,000. The line itself can run up to $750,000, but anything over $500,000 is for primary residences only.
Why does the line require drawing most of it at closing?
The wholesale programs require at least 75% of the line to be drawn at closing. That means you start paying on most of the balance right away, even if you do not need it. A smaller line may fit better if you want to hold part of it back.
Can my LLC take out a HELOC?
No. HELOC title must be held by an individual or a revocable living trust. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance may be the better fit.
