The Quick Read: A HELOC does not buy the property; it supplies the cash for a down payment, and a separate purchase loan, often a DSCR loan, buys the property, so the best program depends on which asset secures the line, how much combined leverage it allows, and whether the purchase lender accepts borrowed funds. You keep your stocks and funds invested. You also take on a second monthly obligation.
- Collateral drives everything. On this network, a line on an investment property tops out at 70% CLTV and $500,000. A line on a primary residence or second home can reach 90% CLTV, but only with a 720 or better credit profile.
- The line is underwritten to you, not to the rental. The HELOC lender looks at your credit, equity, and debt. The new property’s rent does not matter to that line.
- The purchase lender gets a vote. Confirm whether borrowed down-payment funds are acceptable before you draw a dollar.
- DSCR does not count your HELOC payment. Clearing 1.00 on the new rental does not mean your total cash flow works.
- A securities-backed line is the other way to avoid selling. It carries its own risks, covered below.
Lendmire is a mortgage broker. It places these lines through select wholesale partners, and every figure below is subject to lender guidelines and full file review.
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.
Key Terms Defined
HELOC: A home equity line of credit, a revolving credit line secured by a property you own. You borrow what you need, up to a limit.
CLTV (combined loan-to-value): Your existing mortgage plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line, usually paying interest only. A repayment period follows.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly payment: principal, interest, taxes, insurance, and any HOA dues. The lender uses it to judge whether a rental pays for itself.
SBLOC (securities-backed line of credit): A credit line secured by a taxable brokerage account instead of a house.
Source of funds: The paper trail showing where your down payment came from.
What “Best HELOC Program” Means Here
The best program is the one that matches your collateral, title, credit, and purchase plan. There is no universal winner. Anyone who names one without asking those questions is selling something.
Think of it as two separate loans. The HELOC is a funding tool. The purchase loan is the mortgage on the new rental. Each has its own approval, and one can sink the other.
Four questions decide the fit:
1. Which asset secures the line?
2. Will the purchase lender accept borrowed funds?
3. Can your monthly budget carry the line’s payment?
4. How will you pay the line back?
Collateral comes first, because it sets the leverage ceiling:
| Collateral | Max CLTV | Line size |
|---|---|---|
| Primary residence | Up to 90% (720+ credit only) | $25,000–$750,000 |
| Second home | Up to 90% (720+ credit only) | $25,000–$500,000 |
| Investment property | 70% | Up to $500,000 |
Pause on that last row. Many investors assume the rental they already own is the obvious place to pull cash. Our wholesale network treats it more tightly than your own home, with a lower ceiling, a smaller maximum line, and a 700 credit floor. Lendmire’s piece Best HELOC Program to Buy a Rental Without Selling Other Investments covers the broader strategy.
How Underwriting Treats the Line, Step by Step
The HELOC lender underwrites you. It does not underwrite the property you plan to buy. Here is the sequence most files follow.
Step 1: Pick the collateral. Your home, a second home, or an existing rental. The choice sets your CLTV ceiling and line size.
Step 2: The lender checks your credit. The network’s floor is 600, and the score model is a single-bureau pull keyed to the primary wage earner. Investment-property lines start at 700. Credit reports can be no more than 90 days old at closing, and rescores are not allowed.
Step 3: The lender checks your debt load. The maximum debt-to-income ratio is 50%. It drops to 45% for credit profiles from 600 to 679, and anything above 45% needs 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.
Step 4: The lender values the property. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may need a secondary valuation. Every line above $500,000 gets a full appraisal, and you can request one anyway. Because an investment line caps at $500,000, it commonly closes without one.
Step 5: You close and receive the draw. Here is a detail most explainers skip. At least 75% of the line is drawn at closing. This is not a standby line you can leave untouched until a deal appears. You borrow most of it on day one and pay interest on it. Plan the timing so the cash does not sit idle.
Step 6: You document the cash. The purchase lender will want the line agreement, the draw record, and the bank statement showing the money reaching title or escrow. Keep every page.
Your credit pull also hits all your financed properties. Housing history is reviewed across every property you finance, and the standards differ by program, so a late payment on a rental matters here too.
Sizing the Line
The formula is simple: property value × the CLTV cap − your current mortgage balance = the most you could borrow. Work it in percentages, not dollars.
Say your primary residence carries a mortgage equal to 50% of its value, and you have a 720 or better credit profile. A 90% CLTV cap leaves room for a line up to 40% of the home’s value. Drop to a 700 credit profile and the top tier is off the table.
Now run an investment property with a mortgage at 45% of value. The 70% CLTV cap leaves up to 25% of value, and the $500,000 maximum applies on top of that.
Compare that to what the purchase needs. Most DSCR purchase files land at 75%–80% LTV, which means 20%–25% down. Select programs reach 85% LTV with roughly a 700+ score, so 15% down. Add closing costs and reserves, which commonly run around 6 months of PITIA (principal, interest, taxes, insurance, plus HOA dues if any). A conservative rate-term file at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months. Reserves vary by lender, leverage, and loan size.
Reserves often come from your own funds, not borrowed ones. Ask before you assume a HELOC can cover them.
The Structures That Exist
The network’s HELOCs are standalone lines in first or second lien position. Lendmire brokers them through two wholesale programs, one built for higher leverage and one with a longer interest-only runway. Their details differ, so each figure below belongs only to its own program.
Primary residences and second homes can use one of two draw structures:
| Structure | Draw (interest-only) | Repayment (amortizing) |
|---|---|---|
| Shorter | 3 years | 17 years |
| Longer | 5 years | 25 years |
Investment lines use the 5-year draw and 25-year repayment structure only.
Pricing floats through both the draw and repayment periods and never converts to fixed. That differs from the general market, where the CFPB notes that some plans let you convert part of the balance to a fixed rate and that draw periods can last 10 years, for example. Do not count on a fixed-rate conversion here. Subsequent draws after closing carry a $1,000 minimum, which is stated by the longer-runway program. The higher-leverage program does not state one.
Other structural limits:
- Line size: $25,000 to $750,000. A line above $500,000 is primary-residence only, needs a credit profile of 700 or better (720 on the longer-runway program), caps at 75% CLTV, and requires a full appraisal.
- Exposure: You 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.
- Portfolio size: A borrower with more than 15 financed properties is not eligible.
- Property types: Single-family, 2–4 units, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.
- Availability: HELOCs are available only in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint.
Where the General Rule Breaks
“Use a HELOC for the down payment” works until one of these edge cases bites.
Title held in an LLC. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on a HELOC. Only you personally or a revocable living trust can. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. This is the sharpest structural difference between a HELOC and a DSCR loan. DSCR loans to LLC borrowers are subject to lender program eligibility.
Borrowed funds and the purchase lender. Some DSCR programs accept a documented HELOC draw for the down payment but not for reserves. Others have their own policies on borrowed funds, and some want funds to sit in your account for a stretch so the source is clear. Programs vary, and this is a purchase-lender decision. Get the answer in writing before you draw, and ask your broker to shop programs for you.
Stacked leverage. Say you buy at 75% LTV and fund the down payment entirely with a HELOC. Your combined debt across both properties approaches 100% of the purchase price. A dip in values or rents hits hard when you have almost no equity cushion. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Prepayment penalties. A DSCR purchase loan often carries a prepayment penalty that steps down over several years. If your plan is to refinance the new rental and repay the line, that penalty can block the refinance. Ask about it before you buy.
Payment reset. When the draw period ends, repayment begins. The CFPB’s HELOC booklet warns that payments can rise sharply at that point, and it advises collecting three HELOC estimates before you pick one. Because pricing on these lines floats, your payment can also move month to month.
The correlated downturn. Markets fall, home values fall, and the rental sits vacant, all at once. Meanwhile your line payment keeps coming due. A lender can also freeze or reduce a line in a downturn. Plan an exit that does not depend on borrowing more.
Borrowing Versus Selling: How to Weigh It
Selling investments to fund a down payment can trigger a taxable gain and removes shares from future growth. A line avoids both. It also adds interest cost and risk that selling does not.
Run your own comparison on three inputs: your taxable gain if you sold, your expected growth if you hold, and what the line costs you for the full time you carry it. Use your own figures. The cleanest sell-versus-borrow math is the kind you run with your CPA.
An SBLOC is the other tool. AssetMark explains that it is a revolving line secured by a taxable brokerage portfolio, typically non-purpose, meaning it can fund real estate but cannot buy more securities. Fidelity says you keep the securities, their growth, and their dividends, and avoid realizing capital gains. It also warns that you could lose investments if payments are not made, and a minimum portfolio value may be required. Forbes adds that SBLOC pricing floats over SOFR, often sits above mortgage pricing, and suits short-term use better than a long-term strategy.
| Factor | Home equity line | Securities-backed line |
|---|---|---|
| Collateral | Real estate | Brokerage portfolio |
| Main risk | Line freeze, foreclosure | Collateral call, forced sale |
| Best use | Longer carry | Short bridge |
| Underwriting | Credit, equity, DTI | Portfolio value |
Brokerage lines are not something Lendmire arranges. They come from your brokerage firm. A home equity line is where a broker adds value, because the wholesale network shops multiple programs against your credit, equity, and leverage.
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 the DSCR Purchase Loan Needs Next
Once the down payment is in hand, a DSCR loan buys the rental. For a full walk-through, see the complete DSCR loans guide. 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. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Here is what a typical file looks like across the network:
- Purchase leverage: Most files land at 75%–80% LTV.
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Credit: A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).
- Structure: The 30-year fixed is the spine. Interest-only periods and 40-year terms are available through select lenders.
One reminder. A DSCR above 1.00 is not positive cash flow. The ratio compares rent to the payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. And your HELOC payment is not in the ratio at all. Your bank account still pays it every month.
The strongest files clear two tests: enough equity to fund the cash and enough rental coverage to carry the loan. A larger down payment can lower the monthly obligation and lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility.

Who Should Skip This
Skip the strategy if any of these apply:
- You could not carry the line’s payment for a year from your own income if the rental sat empty.
- Your existing mortgage plus the new line would leave you with almost no equity cushion.
- Your rental is deeded to an LLC and you do not want to change title.
- The rental you want to buy is a manufactured home, a log home, or a barndominium, and those property types are not offered in the DSCR network.
- You are leaning on the HELOC for reserves as well as the down payment.
- You cannot tolerate a payment that moves.
Practical Next Steps
Sequence matters. Confirm the purchase lender’s rules on borrowed funds first. Then open the line. Then draw, document, and close the purchase. Do not reverse that order.

Frequently Asked Questions
Can I use a HELOC on my own home as the down payment for a rental?
Often, yes, but the purchase lender decides. Some DSCR programs accept a documented draw for the down payment and want reserves from your own funds. Others set their own limits on borrowed money. Check before you draw, and keep the line agreement and draw record.
Does a HELOC payment count against my DSCR?
No. DSCR tests the new rental’s rent against that property’s own payment. The HELOC is a personal obligation outside the ratio. On loans that review your personal debt-to-income ratio, the line’s payment can count, so budget for it either way.
Can I get a HELOC on a rental I already own?
Sometimes. On this network, an investment-property line requires a 700 credit profile, caps at 70% CLTV, and tops out at $500,000. It must be held in your name or a revocable living trust. Many banks will not write one at all.
Is a securities-backed line safer than a HELOC?
Neither is safe in the abstract. A brokerage line puts your portfolio at risk, and a home equity line puts your house at risk. The better choice depends on which asset you can afford to expose and how long you will carry the debt.
How much of the line do I have to borrow at closing?
At least 75% of the line is drawn at closing on both wholesale programs. Size the line to the cash you need, not the maximum you qualify for, so you are not paying interest on idle money.
