The Quick Read: The best program is the one that pairs a line your equity and credit can support with a purchase lender that accepts borrowed funds for the down payment, because a line only supplies cash and a separate loan still has to buy the property. Both sides have to say yes, and the line has to close first.
- A home equity line of credit (HELOC) gives you cash. It does not buy the rental.
- On investment property the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a $500,000 maximum line. Subject to lender guidelines.
- Primary-residence and second-home lines reach higher leverage, but the top 90% tier requires a 720-or-better credit profile.
- The purchase lender decides whether borrowed funds count for the down payment, closing costs, and reserves. Ask before you draw.
- Clearing the rental’s coverage test does not mean the deal cash flows, because the line payment comes out of the same rent.
What Does the Best HELOC Program for a Down Payment Look Like?
The best program depends on your situation, not on a brand or a headline number. It is a pairing: line terms you can carry, on a property that is eligible, with a purchase lender whose policy accepts the funds.
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.
Lendmire is a mortgage broker. It works with a network of wholesale HELOC lenders and does not lend itself. That matters here because no single lender’s page tells you which program fits. A broker that sees several sets of guidelines can match your scenario to the right one.
Five things decide the match:
- Which property secures the line. Your primary home, a second home, or a rental each carry different ceilings and different risk.
- Credit profile. Higher scores unlock higher combined leverage.
- How much cash you need. Size the line to the down payment plus closing costs, not to the most equity you could pull.
- Draw and repayment structure. A short-term cash need and a long hold call for different setups.
- What the purchase lender will accept. A great line is useless if the next lender will not count the money.
How Does the Sequence Work, Start to Finish?
The order matters more than most investors expect. You close the line first, then shop for the purchase loan, then draw. The two loans are separate approvals.
1. Size the need. Add the down payment and closing costs. Most DSCR purchases on the network land at 75%–80% loan-to-value (LTV), which means about 20%–25% down. A select tier reaches 85% LTV on a purchase, which is about 15% down, usually with a 700-plus score. Subject to lender guidelines.
2. Pick the property that secures the line. Rental lines are harder to find at large retail lenders, which is one reason a broker’s access to several wholesale programs helps. Putting the line on your home ties your residence to the debt. Putting it on a rental ties that rent to two liens.
3. Close the line before you shop. The line cannot close alongside the purchase. It needs to be open and funded-ready when you go under contract.
4. Ask the purchase lender three questions. Are borrowed funds accepted for the down payment? For closing costs? For reserves?
5. Draw and document. Expect to show statements that trace the draw and where the cash landed.
6. Run the coverage test on the new property. Then run your own stress test on every payment stacked together.
7. Plan the exit. Common routes are paying the line down from savings, from sale proceeds, or from a later cash-out refinance after the property is stabilized.
One detail changes the sizing math. On this network, at least 75% of the line is drawn at closing. You start paying on most of the balance right away, so a line sized far above your need costs you money from day one.
What Do the Network’s Line Terms Look Like?
Ceilings differ by occupancy, so never quote one number for all three. The table below summarizes the range for the wholesale programs Lendmire places files with. Figures are typical guidelines, not commitments, and every file is reviewed individually.
| Secured by | Max CLTV | Min credit | Max line |
|---|---|---|---|
| Primary residence | Up to 90% at 720+ | 600 | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | Up to 90% at 720+ | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
Read the table with care. The 90% tier exists only at a 720-or-better profile, and only on lines up to $500,000. On a primary residence, a line above $500,000 needs a 700 score or better (720 on the longer-runway structure described below), caps at 75% CLTV, and requires a full appraisal. Lower credit tiers step the ceiling down. A 640 profile on a primary residence, for example, sits at 80% CLTV.
Investment-property lines are the tightest. The ceiling is 70% CLTV, and no tier sits above it. That is a real constraint if you planned to pull the most equity out of an existing rental.
Draw and repayment structures
Two structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other has a 5-year interest-only draw followed by a 25-year repayment, and it is the longer-runway option. Investment lines run only the 5-year draw and 25-year repayment. Pricing floats during both phases and never converts to fixed.
For context, a Yahoo Finance explainer describes a typical market HELOC as a 10-year draw with roughly 20 years of repayment. That is a market-wide description. The network figures above are the ones that apply here.
Other line rules worth knowing
- A line can sit in first or second lien position.
- Debt-to-income (DTI) tops out at 50%, and drops to 45% for credit profiles from 600 to 679. The line is qualified on the interest-only payment at the maximum draw.
- Lines at or below $500,000 usually run an automated valuation. A line above $500,000 needs a full appraisal.
- Eligible collateral includes single-family, 2–4 unit, PUD, townhome, and condominium properties. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.
- Home-equity lines through this network are available in 16 full-service states, which is narrower than Lendmire’s 41-market DSCR footprint. Check your state before you build a plan around the line.
Will the Purchase Lender Accept Borrowed Funds?
It depends on the program, and you need the answer in writing before you draw. The purchase lender decides whether borrowed money counts, and the answer can differ for the down payment, closing costs, and reserves.
For contrast only: Fannie Mae’s Selling Guide accepts asset-secured borrowed funds for conventional agency loans. DSCR loans are not agency products. They set their own treatment, so that rule does not carry over.
Across the wholesale network, a few patterns show up:
- Down payment. Borrowed funds are most commonly accepted here.
- Closing costs. Often accepted, but confirm.
- Reserves. Often excluded. Reserves are the cushion that proves you can survive a vacancy, so many programs want them from your own unborrowed money. They commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and any HOA dues). They vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months.
- Fully borrowed down payments. Some programs accept them. Others cap the borrowed share or want part of the cash to be your own seasoned funds.
- Higher leverage tiers. These are where borrowed-fund overlays tend to be strictest. You would be financing nearly the whole purchase.
The honest answer on seasoning is also program-specific. Some lenders want the cash to sit in your account for a period before it counts. Ask the purchase lender, not the line lender.
How the Rental’s Coverage Test Treats the Line
The coverage test compares monthly rent to the new property’s PITIA. The HELOC payment generally sits outside that ratio. That is the good news.
Here is the catch. The payment is still real, and it comes out of the same rent. Clearing the coverage test is not the same as positive cash flow. The ratio ignores repairs, vacancy, management, utilities, and capital expenses. Add a line payment on top and the margin shrinks again.
For standard DSCR purchases, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and higher leverage. The complete DSCR loans guide walks through how the ratio is built.
A stacked-payment stress test
Run this check yourself before you draw, using your own real numbers:
1. List the first mortgage on the property securing the line, if any.
2. Add the line payment on the interest-only draw basis. Then add the higher amortizing payment you will face when repayment starts.
3. Add the new rental’s full obligation.
4. Compare the total to the rent you can document, then subtract a realistic vacancy and repair allowance.
If the rent only works in the best case, the plan is thin. Variable pricing can raise the line payment even if you never draw again. The CFPB’s HELOC brochure says a variable payment can change with no new draw, and that payments are often significantly higher once repayment begins.
Where the General Rule Breaks
The rule of thumb is simple: close the line, draw, buy. These edge cases bend it.
An LLC cannot hold title on the line. Home-equity lines through the network require title held by an individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. Subject to program terms.
Your primary home is on the line. Borrowing against your residence puts it at risk if you cannot pay. Nasdaq’s coverage of HELOC down payments flags the foreclosure risk to the primary home directly. Borrowing against a rental instead keeps your residence out of it, but limits you to the 70% CLTV investment ceiling.
The line cannot be a first-lien refinance trap. A DSCR loan generally sits in first position. If you plan a first-lien refinance on the same property, do it before you add a second lien.
Draw period ends. Borrowing stops and the payment resets. On a short-term cash need, that reset is part of the plan, not a surprise.
Property listed for sale. In NC, PA, TN, TX, and WA, a property listed for sale, or listed within the past 60 days, is ineligible.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. A foreclosure on an investment file follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path.
Exposure limits. A borrower is limited to three lines, with combined exposure capped 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. Experienced portfolio investors hit this limit before they hit the equity limit.
Texas primary residences. A Texas primary is a homestead with extra rules, including a 12-day waiting period and a one-lien-at-a-time rule. Second homes and investment properties there are treated as non-homestead transactions.
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.
Which Line Fits Which Investor?
Think in scenarios. These are patterns the network sees, not guarantees.
Owner of a primary home with strong equity and a 720-plus profile. The primary-residence tiers give the most room. A modest line sized to the down payment keeps the draw small and the payment manageable. The tradeoff is that your home secures it.
Investor with several rentals and one clean, low-leverage property. The investment line runs up to 70% CLTV at a 700 score or better. Leverage is lower, but your residence stays out of it. Watch the three-line exposure limit.
Investor whose properties sit in LLCs. The line is not available against LLC-titled property. The better route is often a DSCR cash-out refinance.
Buyer who needs most of the cash from borrowed money. Expect the toughest questions from the purchase lender. Higher leverage tiers carry stricter overlays on borrowed funds, so line up a lender that accepts them before you draw anything.
Borrower buying a rental specifically. The purchase lender will want to see the rent supports the loan. Lendmire’s article Best DSCR HELOC Program for a Down Payment on Your Next Rental covers that pairing in more detail.
Key Terms Defined
HELOC (home equity line of credit): A revolving credit line secured by a property you own, which you can draw from during a set draw period.
CLTV (combined loan-to-value): All loans secured by the property added together, divided by the property’s value.
Draw period: The first phase of the line, when you can borrow and typically pay interest only.
Repayment period: The second phase, when borrowing stops and the balance is paid down in full amortizing payments.
PITIA: Principal, interest, taxes, insurance, and any HOA dues, which is the full monthly obligation the coverage test measures.
DSCR (debt service coverage ratio): The property’s monthly rent divided by its PITIA.
Reserves: Liquid funds, often counted in months of PITIA, that a lender wants you to hold after closing.
Frequently Asked Questions
Can a HELOC cover my entire down payment on a rental?
Sometimes, but it depends on the purchase lender. Some programs accept a fully borrowed down payment. Others cap the borrowed share or want part of the cash to be your own seasoned money. Higher leverage tiers tend to be strictest. Ask before you draw, and expect reserves to come from unborrowed funds.
Does the HELOC payment lower my DSCR?
Generally no. The ratio compares rent to the new property’s PITIA, and the line payment sits outside it. But that payment still comes out of your real cash flow. A property can clear the coverage test and still run tight once you subtract the line payment, repairs, and vacancy.
What credit score do I need?
It depends on what secures the line. The program floor is 600 on primary residences, 640 on second homes, and 700 on investment properties. Higher scores unlock higher leverage. The 90% tier requires 720 or better. Subject to lender guidelines and full file review.
Should I borrow against my home or against a rental?
Borrowing against a rental keeps your residence out of the risk, but investment lines cap at 70% CLTV. Borrowing against your primary home allows higher leverage, but your residence secures the debt. The right choice depends on how much cash you need and how much risk you will carry.
Can I use a HELOC if my rental is owned by an LLC?
Not on the line itself. LLCs and similar entities cannot hold title on these lines. A DSCR cash-out refinance is often the better route for LLC-titled property. Subject to program terms.
