The Quick Read: A HELOC has no down-payment rules of its own: the line lender decides how much you can borrow against your equity, and the purchase lender decides whether those borrowed dollars count as your cash in, so the right fit depends on which property secures the line, your credit profile, and the program you buy with. Across the wholesale network Lendmire works with, the ceilings depend on occupancy, and the top tier is narrower than most borrowers expect.
- On an investment-property line, the ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit profile and a line up to $500,000.
- On a primary-residence or second-home line, the ceiling reaches 90% CLTV only at a 720-or-better credit profile, on lines up to $500,000.
- Whether borrowed funds count toward your down payment is decided by the purchase program, so ask before you draw.
- A DSCR purchase of an investment property typically lands at 75%-80% LTV, so borrowing the down payment does not remove the rental coverage test.
- The line’s payment sits outside the DSCR ratio, but your rent still has to help carry it.
How a HELOC Fits Into a Home Purchase
A home equity line of credit (HELOC) is a revolving line secured by a property you already own. You borrow against the equity, and the cash can go toward a down payment on the next purchase. That is the whole concept. The complication is that two separate lenders touch the deal.
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.
The line lender asks one question: do you have enough equity, credit, and income to hold this line? The purchase lender asks a different one: where did your down payment come from, and does our program accept it? Passing the first test says nothing about the second.
Yahoo Finance notes that line funds can go to a down payment, closing costs, or other expenses up to the approved limit. That flexibility is why investors like lines. It is also why the purchase lender wants a paper trail.
Here is how the pieces interact in practice. The line closes first. You draw cash into your own account. The purchase lender then reviews the file as its own transaction. On a DSCR purchase, that review centers on the rental’s income against its own payment.
“Best” is a loaded word here. No single line wins for everyone. The best program for your situation depends on which property secures the line, your credit tier, how much cash you need, and what the purchase lender accepts.
Key Terms Defined
HELOC: A revolving line of credit secured by a property you own, with a draw period when you borrow and a repayment period when you pay it down.
CLTV (combined loan-to-value): All loans secured by the property, added together, divided by the property’s value.
DSCR (debt service coverage ratio): The property’s monthly rent divided by its monthly payment of principal, interest, taxes, insurance, and any HOA dues. Select programs start at 1.00.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the full monthly housing payment on a property.
Seasoning of funds: The time money has sat in your account, with a document trail, before a lender accepts it as yours.
Vesting: The name or entity that holds legal title to a property.
Which Property Secures the Line? Three Routes Compared
The network’s equity-line programs set different limits depending on occupancy. This is where most borrowers pick the wrong route.
| Property securing the line | Max CLTV | Min credit | Max line |
|---|---|---|---|
| Primary residence | 90% (720+ only) | 600 | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 90% (720+ only) | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
Those are program ceilings, not typical outcomes. On a primary residence, lower credit tiers step the ceiling down: 85% CLTV at 660 through 700 for lines up to $500,000, 80% at 640, 70% at 620, and 60% at 600. A line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the longer-runway program, one of two wholesale programs in the network), caps at 75% CLTV, and requires a full appraisal. Every figure is subject to lender guidelines and full file review.
On this network, an investment-property line stops at 70% CLTV.
Two practical points follow:
- Home equity is the common source. Many investors pull from their primary residence because the ceiling is higher and the credit floor is lower.
- Rental equity is available, with a lower ceiling. A line on an existing rental caps at 70% CLTV and wants a 700 profile. It also keeps the debt attached to the investment instead of your home. A BiggerPockets Rookie episode notes that banks often limit lines to primary residences, which is part of why line-on-a-rental options matter.
Lendmire’s piece Best Investment Property HELOC Program to Cover a Down Payment on Another Home goes deeper on that second route.
How the Sequence Works, Step by Step
Order matters more than most borrowers realize. Doing it in the wrong order is the most common way to end up with a line you cannot use.
1. Ask the purchase side first. Before you open anything, find out whether the purchase program accepts borrowed funds for the down payment. Ask whether it caps the borrowed share. Ask whether it wants part of the money unborrowed.
2. Check your equity. Equity is your property’s value minus what you owe. The line is sized against it, and CLTV counts your first mortgage plus the new line.
3. Open the line. For lines at or below $500,000, the network ordinarily runs an automated valuation with no traditional appraisal. A higher CLTV may trigger a second valuation, and you can request a full appraisal anytime. Above $500,000, a full appraisal is required.
4. Draw. At least 75% of the line is drawn at closing on both wholesale programs. That means you are borrowing most of the line from day one. Do not open a large line just to have it available.
5. Season and document the cash. Keep the line closing documents, the draw confirmation, and bank statements showing the deposit. The purchase lender will want that chain.
6. Run the purchase. The purchase lender reviews the rental on its own merits, separate from the line.
7. Plan the payoff. The line is not free money. You need a plan for what happens when the draw period ends.
The line lender also tests your personal finances. DTI (debt-to-income) tops out at 50% on the network’s lines. It drops to 45% for credit profiles from 600 to 679, and a ratio above 45% requires a 680 minimum. The test uses the interest-only payment calculated on the maximum draw. Keep that in mind if your other debts are already heavy.
Will the Purchase Lender Accept Borrowed Funds?
It depends on the program. Some DSCR programs accept borrowed money toward the down payment. Others require a minimum of your own funds or cap the borrowed share. Across the wholesale network, borrowed-funds treatment is program-specific, which is why step one above is asking.
Think of your cash needs as three separate pots:
- Down payment. Typically 20%-25% on a DSCR purchase of an investment property, since most files land at 75%-80% LTV. Select programs reach 85% LTV (15% down) with roughly a 700-plus score.
- Closing costs. Some programs treat these differently from the down payment.
- Reserves. Commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Borrowed money is commonly excluded from reserves even where it counts toward the down payment.
The same dollars generally cannot serve as both the down payment and the reserves. A file can look fine on paper and still fail because all the cash was borrowed and nothing sits in reserve.
Here is a simple script for your purchase lender or broker before you draw:
- Does this program accept line proceeds toward the down payment?
- Is there a cap on the borrowed share?
- Do you want the cash seasoned, and with what documents?
- Will borrowed funds count toward reserves?
- Does the account receiving the draw have to be in the borrower’s name or the entity’s?
If the answer to any of these is no, find that out before the line closes. Not after.
Lendmire’s piece Best DSCR HELOC Program for a Down Payment on Your Next Home covers the borrowed-funds question from the DSCR side.
Where the General Rule Breaks
Equity lines look simple until one of these catches you.
Title and vesting. The line is held by you as an individual or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on a line. A property already deeded to an LLC needs a vesting change first. Or you skip the line and use a DSCR cash-out refinance instead. This is the sharpest structural difference from a DSCR loan, which can close in an LLC subject to lender program eligibility.
Property type. Eligible: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Not eligible: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agricultural zoning. Modular factory-built homes are eligible on the longer-runway program only. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network.
Exposure. A borrower can hold up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible. Portfolio investors hit this wall.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits on primary residences and second homes. One program seasons a foreclosure in 7 years and a deed-in-lieu, pre-foreclosure, or short sale in 4. The other declines the history entirely, regardless of age. Investment files follow the 7-and-4-year path.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible for a line in several states.
Availability. Lendmire brokers equity lines in its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint. Lendmire is a broker, not a lender, and every figure here is subject to lender guidelines and full file review.
A fully borrowed down payment. Some purchase programs accept it. Even where one does, you may end up with little equity and no cash. One more thing to weigh: you would then owe the first mortgage on your home, the line, and the new rental loan all at once.
What the DSCR Purchase Side Wants
Once the cash is in your account, the purchase gets underwritten on its own. This is where the complete DSCR loans guide picks up. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal DTI is not the test.
Across the network, typical program figures look like this:
- Purchase leverage: most files land at 75%-80% LTV on a purchase of an investment property. Select programs reach 85% LTV with roughly a 700-plus score.
- Coverage: 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit: a 620 floor exists in parts of the network. Most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
- Reserves: commonly around 6 months of PITIA. Loans above $1,500,000 typically step up to about 9 months.
A bigger down payment lowers the monthly payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Here is why a pure rental purchase usually ends up on a DSCR loan. Conventional and full-doc programs add the line’s payment to your personal DTI before they weigh the new payment. A DSCR program tests the rental’s income against the rental’s payment. Your existing mortgages do not cap borrowing the same way. (The line itself still gets a DTI test, which is why you check both sides.)
One more caution. Clearing 1.00 does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the number.
A Worked Scenario, Without the Dollar Signs
Consider two investors buying the same rental. Both have a 720 credit profile, a primary residence with solid equity, and a DSCR purchase at 75% LTV. Assume, as a modeled input and not a market fact, that the rent clears about 1.2x coverage on the rental loan. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Investor A draws a line sized to cover part of the 25% down payment. She brings her own cash for the rest, plus closing costs and reserves. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Investor B borrows the full 25%. His purchase program accepts borrowed funds for the down payment, but not for reserves. So the question becomes where six months of reserves comes from.
Both rentals show the same 1.2x ratio. The ratio never counted the line. But Investor B now carries the home’s first mortgage, the line payment, and the rental loan. The rent has to help carry the line in real life, even though the DSCR test ignores it. The line also floats with the market, so that payment can move.
Honestly, this is a close call for most people. Investor A’s structure is slower to build, but it survives a vacancy. Investor B’s structure works until the first one.
Costs and Risks You Should Price In
Your home is the collateral. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly during a draw period, followed by a repayment period when you can no longer borrow. Payments are often significantly higher once repayment starts. In some plans the whole balance can come due at that point. The network’s structures run a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Investment lines run the 5-year draw and 25-year repayment structure only. Pricing floats across both periods and never converts to fixed.
The CFPB’s HELOC booklet adds two points. Monthly payments may change even if you draw nothing more. And if you sell the home securing the line, you are generally required to pay it off in full.
A line can also be frozen or reduced if home values decline, per the same booklet. That matters if you plan to rely on the undrawn portion for repairs.
Who This Fits (and Who Should Skip It)
A line tends to fit when you:
- Own a primary residence or second home with substantial equity and a 700-plus credit profile.
- Want to keep savings liquid for reserves and rehab.
- Have confirmed your purchase program accepts borrowed funds.
- Have rent that can carry both payments with room to spare.
Skip it, or shrink it, when you:
- Plan to borrow the entire down payment and keep no reserves.
- Hold your property in an LLC and cannot change vesting.
- Have a tight DTI already. The 50% ceiling is firm.
- Need a long hold with no repayment plan. Short-term acquisitions fit lines better than a 30-year hold.
Frequently Asked Questions
Can a HELOC cover the entire down payment?
Sometimes, but it depends on the purchase program. Some accept a fully borrowed down payment while others require a minimum of your own funds or cap the borrowed share. Even where it is allowed, the borrowed dollars are commonly excluded from reserves. Ask the purchase lender before the line closes.
Does the HELOC payment affect my DSCR?
No, the ratio only compares the rental’s rent to the rental’s payment. The line’s payment is a personal obligation, though, and the line lender runs its own DTI test. In real life, your rent still helps carry it.
Can my LLC take out the line?
No. A line is held by you as an individual or by a revocable living trust. LLCs, corporations, and partnerships cannot hold title on it. The DSCR purchase itself can often close in an LLC, subject to lender program eligibility.
What if the purchase lender will not accept borrowed funds?
Bring more of your own cash, or look at a lower-leverage structure. Another option is a DSCR cash-out refinance on a rental you already own, which tops out around 75% LTV with about 6 months of seasoning. That route may also be treated as borrowed, so confirm first. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Is the line secured by the property I’m buying?
No. The line described here sits on a property you already own and hold in your own name. The new rental is financed separately through its own purchase loan.

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. An illustrative calculator on the site can give you a rough sense of the structure before you talk to anyone.
The strongest down-payment plans treat the line and the purchase as two separate approvals, each with its own limits, and are built backward from the purchase lender’s rules.
