The Quick Read: The right program is the one whose equity limit, credit floor, and draw structure fit the property that will secure the line, and whose cash your rental purchase lender will accept as a down payment.
- A home equity line of credit (HELOC) supplies cash only. A separate loan buys the rental.
- Occupancy sets the ceiling. Across our wholesale network, investment-property lines top out at 70% combined loan-to-value (CLTV), while primary-residence lines can reach higher.
- Most DSCR purchase loans land at 75% to 80% loan-to-value (LTV) on a purchase, so you usually need 20% to 25% down, plus closing costs and reserves.
- The line payment sits outside the DSCR math but still comes out of your pocket.
- Programs differ on how much borrowed money they allow, so ask before you draw.
How Does a HELOC Down Payment Actually Work?
A HELOC down payment is two separate loans on two separate files. The line is sized on the property that secures it. The rental purchase is sized on the target property’s rent. Neither approval guarantees the other.
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.
Here is the sequence, start to finish:
1. Equity is measured. Equity is what the home is worth minus what you owe. A lender caps the first mortgage plus the new line at a percentage of value. That cap is the combined LTV.
2. The line is approved and closed. The lender reviews credit, debt-to-income (DTI), and the home’s value. DTI compares your monthly debts to your income.
3. You draw cash into your own account. The money sits in a bank account in your name, where it leaves a clear paper trail.
4. The rental purchase file is built. The new loan reads the rent against the full monthly payment. Lenders also review credit, assets, reserves, and the appraisal.
5. The purchase closes. The borrowed cash goes in as part or all of the down payment, if that lender allows it.
Benzinga’s explainer makes the same basic point: the line on your current home can fund the next purchase, if you have enough equity. We see this structure often. The sharp part is not the line itself. It is whether the second lender accepts what the first one gave you.
A debt service coverage ratio (DSCR) loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. That is why this pairing fits investors well. The line does not feed the rental’s coverage number, so it does not weaken the rent test. The details of that loan type are in Lendmire’s complete DSCR loans guide.
Which HELOC Program Is Best as a Down Payment on Another Home?
No program wins for everyone. The best program for your situation depends on the property securing the line, your credit profile, how much cash you need, and what the purchase lender will accept. Lendmire is a mortgage broker. It works with a network of wholesale HELOC lenders and matches your file to the program that fits.
A single lender can only show you its own guidelines. A broker compares several. That matters here because programs differ on credit floors, draw length, and which properties they accept. Judge any program on these points:
| Feature | Why it matters | What to ask |
|---|---|---|
| Max CLTV for your occupancy | Sets how much cash you can reach | What is the ceiling at my score? |
| Credit floor | Decides if the line is open to you at all | Where do the tiers start? |
| Draw and repayment structure | Shapes the payment step-up later | How long is the interest-only draw? |
| Minimum draw at closing | Drives the interest you carry | How much must be drawn at closing? |
| Title rules | Rules out entity-held property | Who can hold title? |
| Valuation method | Affects cost and the value you get | Is an appraisal required? |
Size the line to the actual cash need. On the programs we place, at least 75% of the line is drawn at closing. You carry interest on that draw whether you need it or not. An oversized line costs real money.
Which Property Secures the Line?
The occupancy of the property that secures the line sets your limits. A line on your primary home gets the most room. A line on a rental gets the least. Figures below are program ceilings across our network, subject to lender guidelines and full file review.
| Occupancy | Min credit | Max CLTV | Max line |
|---|---|---|---|
| Primary residence | 600 | 90% (only at 720+) | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 640 | 90% (only at 720+) | $500,000 |
| Investment property | 700 | 70% | $500,000 |
The 90% ceiling exists only at 720 or better, and only up to a $500,000 line. At 700 and above, a primary residence reaches 85% on lines to $500,000. At lower tiers the ceiling steps down. A 640 score on a primary residence, for example, caps at 80%. Use the table above for the full set of figures.
A line above $500,000 is available on a primary residence only. It requires a credit profile of 700 or better (720 on the longer-runway program, described below), caps at 75% CLTV, and requires a full appraisal.
A line on a rental sounds tempting because the equity is already there. The cap is lower, though, and the credit floor is higher. Lenders can also view the line as riskier, as Benzinga notes. The rental itself becomes the collateral.
Also, a property deeded to an LLC cannot secure these lines. Title must sit with you personally or in a revocable living trust. An LLC-held rental needs a title change, or a DSCR cash-out refinance instead.
How Does Underwriting Treat the Line and the Purchase?
Two sets of underwriting apply. Each one asks its own questions.
The line. The lender reviews your credit report, your DTI, and the home’s value. Across our network:
- Credit floors run from 600 on primary residences to 700 on investment properties.
- DTI tops out at 50%. It is 45% for profiles from 600 to 679, and anything over 45% needs at least a 680.
- The lender reviews your file on the interest-only payment calculated on the maximum draw, not your actual draw.
- Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. You can request a full appraisal anyway. A higher CLTV may call for a secondary valuation.
- A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits. One program declines it entirely on primary residences and second homes. The other accepts a foreclosure after 7 years and a short sale or deed-in-lieu after 4.
The purchase. The DSCR lender divides the property’s rent by its full monthly payment: principal, interest, taxes, insurance, and any HOA dues. On most files, 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. Treat the ratio as a lender’s test, not a profit forecast.
Most purchase files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700 score or better. Most programs want around 660 on credit. A 620 floor exists in parts of the network. A score of 700 or higher unlocks the strongest tiers.
Now the part most investors miss. Down payment, closing costs, and reserves are three separate pots. Reserves are months of your payment held in the bank after closing, and the amount required varies on a DSCR file. They vary by lender, leverage, loan size, and transaction type. Some conservative rate-and-term files at modest leverage can see reserves waived, and larger loans step up. Borrowed funds are often accepted for the down payment. They are commonly excluded from reserves. Treat that as a pattern, not a rule, and confirm it with the purchase lender.
What Structures Exist?
The structure of the line affects how long the interest-only period lasts and what happens when it ends. The network includes two wholesale programs. This article calls them the higher-leverage program and the longer-runway program, since each one has its own terms. Where a figure belongs to one of them, it says so.
- Draw structures on primary residences and second homes. One structure has a 3-year interest-only draw followed by a 17-year repayment. The other has a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year, 25-year structure only. A few states shorten these periods.
- Lien position. The line can sit in first or second position as a standalone product.
- Pricing. Pricing floats through both the draw and repayment periods. It never converts to fixed.
- Subsequent draws. After closing, the minimum draw on the longer-runway program is $1,000, except in Texas at $4,000.
- Line size. Lines run from $25,000 to $750,000. Michigan’s floor is $10,000.
- Exposure. 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. A borrower with more than 15 financed properties is not eligible.
- Property types. Single-family homes, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Two-to-four unit properties need a 640 minimum on the longer-runway program. Modular factory-built homes qualify on the longer-runway program only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered on either program.
- Credit depth. The longer-runway program wants two tradelines seasoned 12 months or one seasoned 24. Its housing history standard is 0x30x6 and 1x30x12 at 640 and above, and 0x30x12 from 600 to 639.
Availability matters too. These HELOC programs are offered through Lendmire in 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. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
Where Does the General Rule Break?
The rule says a HELOC works as a down payment. These edge cases are where it stops working.
A fully borrowed down payment. Some purchase programs cap the borrowed share. Some want part of the down payment unborrowed. Others accept it all. A plan that is 100% borrowed can fail on that point alone. Ask before you draw.
An LLC-held rental as collateral. A line needs a natural-person borrower or a revocable trust. If your rental sits in an LLC, the line is out unless you change title. A DSCR cash-out refinance on the LLC-held property is the usual alternative, subject to program terms.
A property that is too new, too odd, or too listed. A recent listing can kill eligibility in several states, depending on the lender and the file. Ineligible property types are simply not offered.
Texas primary residences. A Texas primary residence is a homestead, so combined LTV caps at 80%. Second homes and investment properties follow the standard tables.
Sequencing with a DTI-based loan. If your next loan counts your debts against income, the line payment counts against you. Close the DTI loan first, then open the line. If the next loan is DSCR, the order matters less.
A frozen line. A lender can cut a line if your home’s value falls, according to the CFPB’s HELOC brochure. That is a real risk if you plan to draw in stages. The 75% drawn at closing on our programs reduces that exposure, but it does not remove it.
Tax. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
What Does a Worked Scenario Look Like?
Run the numbers this way. Picture an investor with a 740 score who owns a primary residence. The first mortgage covers about half of the home’s value. At 740 on a primary residence, the ceiling can reach 90% CLTV on a line up to $500,000, subject to guidelines. That leaves roughly 40% of the home’s value in reach, up to the line cap.
The investor wants a duplex purchase at 75% LTV on a purchase. That means 25% down, plus closing costs and reserves. Say the duplex’s rent clears roughly 1.2x its full monthly payment. The line can fill the down payment and part of the closing costs. Reserves come from savings. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Now flip it. The same investor holds only a rental with no primary residence equity. A line on the rental caps at 70% CLTV and needs a 700 score. After the existing mortgage, much less cash is available. A DSCR cash-out refinance on a standard rental, at around 75% LTV and about 6 months of seasoning, may reach further. Seasoning is the wait between buying a property and refinancing it. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
| Path | Cash source | Typical ceiling |
|---|---|---|
| HELOC on primary | Home equity | Up to 90% CLTV (720+) |
| HELOC on rental | Rental equity | 70% CLTV |
| DSCR cash-out refinance | Rental equity | Around 75% LTV, standard rentals |
The best choice depends on which property has the equity and how much cash you actually need.
What Can Go Wrong? (Budget and Stress Test)
You end up with three obligations: your first mortgage, the line, and the new rental loan. If rents underperform, you are doubly leveraged. The DSCR calculation ignores the line payment, so a rental can clear 1.00 and still strain your budget.
Plan for three things:
- The payment step-up. The line is interest-only during the draw. When repayment starts, principal comes due. A 3-year draw gives you less runway than a 5-year draw.
- Variable pricing. The pricing floats and never converts to fixed. Your payment can move.
- Collateral risk. If the line sits on your primary home, that home backs the debt. Benzinga warns of foreclosure risk if you cannot make the required payments. Selling the home generally means paying off the line, according to the CFPB’s HELOC brochure.
The CFPB’s HELOC booklet defines a HELOC as revolving credit secured by your home. It illustrates the usual method for sizing equity: take a percentage of the home’s value, such as 75 percent, and subtract the mortgage balance. That illustration is a general example. Our network’s limits depend on occupancy and credit, as shown above. The booklet’s best tip also fits this decision: get three estimates and compare them. A broker that shops several wholesale lenders does that comparison for you.
Honestly, the stronger play for many investors is a smaller line and a bigger rent cushion. The investor who maxes every limit has the least room if a roof fails.
What Should You Check Before You Apply?
Use this list before opening a line:
- Confirm which property will secure the line and who holds title.
- Check your credit tier against the table above.
- Ask the purchase lender how it treats borrowed down-payment funds, in writing if possible.
- Ask whether borrowed funds count toward reserves.
- Size the line to the cash need, knowing that at least 75% is drawn at closing.
- Gather the line statement and bank statements showing the deposit.
- Confirm the target property is an eligible type.
- Stress-test the three payments against realistic rent and vacancy.

CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value.
DSCR: A ratio of a rental’s monthly rent to its full monthly payment, used to judge whether the property covers its own debt.
Draw period: The early stage of the line, when payments are interest-only.
Seasoning: The waiting period a lender wants between two events, such as buying and refinancing.
Reserves: Months of payments you hold in the bank after closing.
Frequently Asked Questions
Can the line and the rental loan come from the same lender?
Not necessarily. They are separate files with separate guidelines, and a broker can place each with the program that fits it. Matching them matters more than keeping them under one roof.
Does the HELOC payment lower my DSCR?
No. The DSCR calculation compares rent to the rental’s own payment: principal, interest, taxes, insurance, and any HOA dues. The line payment is outside that math. It still reduces your real cash flow, and it can affect other loans that count your debts against income.
Can I put the line on a rental held in an LLC?
Not directly. These lines require title held by you personally or in a revocable living trust. A rental already deeded to an LLC needs a title change first, or a DSCR cash-out refinance instead, subject to program terms.
Is a bigger down payment always better?
It lowers the new loan’s payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear two tests: enough equity and enough rental coverage.
Do I need an appraisal on the line?
Lines at or below $500,000 ordinarily use an automated valuation, though a higher CLTV may call for a secondary valuation. You can request a full appraisal in any case. A full appraisal is required on every line above $500,000.
