The Quick Read: The right HELOC program for a rental purchase is the one whose collateral, credit requirements, and draw structure fit your equity and also satisfy the purchase lender, because the line only supplies cash for the down payment while a separate DSCR loan actually buys the property. Lendmire is a mortgage broker, not a lender. It matches your scenario to select wholesale lenders and does not approve loans itself.
- A home equity line (HELOC) is a source of cash. It never finances the rental.
- On an investment property, the line caps at 70% CLTV (combined loan-to-value) with a 700 minimum credit score, subject to lender guidelines.
- A line on your primary residence usually releases more cash than a line on a rental.
- The DSCR purchase lender decides whether borrowed funds count toward your down payment, closing costs, and reserves.
- Clearing the DSCR test does not tell you whether you can carry both payments. You have to check that separately.
What a HELOC Does in a Rental Purchase
A HELOC does one job here: it turns equity you already own into cash. That cash becomes the down payment, closing costs, and sometimes reserves on a separate purchase loan. For a pure rental purchase, that purchase loan is usually a DSCR loan.
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.
DSCR stands for debt service coverage ratio. It compares the property’s monthly rent to the monthly cost of owning it. That cost is PITIA: principal, interest, taxes, insurance, and any HOA dues. A loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal income is not the headline test.
You end up with two loans and two separate files. The line is underwritten on you and your collateral. The DSCR loan is underwritten on the new property. Neither lender approves the other’s loan.
One timing fact catches people out. You cannot open a line against a property you have not bought yet. The line has to sit on something you already own, which means you build the plan backward from your purchase date.
Two collateral paths
You can put the line on your primary residence or another property you own. Or you can put it directly on an existing rental. Both are real options, and they behave very differently.
| Factor | Line on Primary or Second Home | Line on an Investment Property |
|---|---|---|
| Max CLTV | Up to 90% at 720+ credit | 70% |
| Credit | Tiered, from a 600 program floor | 700 minimum |
| Max line | Above $500,000 on primary only | $500,000 |
| Draw structure | Two structures exist | 5-year draw, 25-year repayment |
Those figures reflect select lenders in the wholesale network Lendmire works with, and every file is reviewed individually. The 90% tier exists only at a 720-or-better credit profile. It does not apply to investment collateral at all.
Key Terms Defined
CLTV (combined loan-to-value): All loans secured by the property, including the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and typically pay interest only.
Repayment period: The stretch after the draw ends, when the balance amortizes and the payment usually steps up.
Seasoning: The time funds have sat in your account, or the time you have owned a property, before a lender treats them as established.
Reserves: Liquid cash a purchase lender wants you to hold after closing, commonly counted in months of PITIA.
Business-purpose loan: A loan made for an investment property rather than a home you will live in.
How Underwriting Treats the Line, Step by Step
Here is the sequence, in the order it actually happens.
1. Measure usable equity. Add every lien on the collateral property and divide by its value. Your usable line is the value times the CLTV cap, minus what you already owe. Say a primary residence has liens equal to 40% of its value. A 70% cap would leave room for about 30% of value, though a primary-residence line can go higher at stronger credit tiers.
2. Qualify the borrower. A line secured by a rental checks your personal credit and your debt-to-income ratio (DTI). It does not look at the rent the property brings in. DTI tops out at 50%, and the payment is qualified on interest-only at the maximum draw. Investment lines need at least a 700 score.
3. Value the property. Because an investment line caps at $500,000, and full appraisals begin only above that amount, it normally runs on automated valuation. You can still request a full appraisal.
4. Close the line first. The line is never closed together with the purchase. At least 75% of the approved line is drawn at closing, so size it to what you need. Subsequent draws after closing carry their own minimums.
5. Move the cash and document it. Draw into your own account, keep the money separate, and keep the paper trail. Applications ask whether funds are borrowed. An undisclosed source can sink the file.
6. Run the DSCR purchase. The new lender checks rent against the new property’s PITIA. Your line payment sits outside that ratio.
7. Plan the exit. You either pay the line down from other cash flow or improve the property and refinance it with a cash-out DSCR loan. The refinance repays the line.
What the Line Looks Like on the Credit Side
The Consumer Financial Protection Bureau describes a HELOC as an open-end line of credit. You can borrow repeatedly up to your limit during the draw period. Its HELOC booklet adds that you can typically borrow only up to a set percentage of your equity.
On investment collateral, that percentage is 70% CLTV on this network. Pricing floats through both the draw and the repayment period and never converts to fixed. Keep that in mind when you plan the exit. A floating-cost line carried for years is a different bet than a short bridge.
How the DSCR Purchase Lender Sees Borrowed Funds
The purchase lender runs three separate tests: down payment, closing costs, and reserves. Treat them as three pots.
Across the wholesale network, borrowed funds are often accepted for the down payment and closing costs when the source is documented. They are commonly excluded from reserves. A few programs cap the borrowed share. The strictest overlays want part of the down payment to come from your own unborrowed money.
So confirm the purchase lender’s rule before you draw. Drawing first and asking later is the most expensive order of operations.
Here is what the purchase side typically looks like, subject to lender guidelines:
- Purchase leverage: Most files land at 75%-80% LTV on a DSCR purchase (20%-25% down). Select programs reach 85% LTV on a purchase (15% down) with roughly a 700+ score.
- Coverage: 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 leverage.
- Credit: A 620 floor exists in parts of the network. Most programs want around 660. A 700+ score unlocks the strongest leverage tiers.
- Reserves: They vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common, and larger loans typically step up to about 9 months.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).
A bigger down payment lowers the DSCR 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 both tests: enough equity and enough rental coverage.

Where the General Rule Breaks
The steps above describe the clean case. These are the edges.
LLC title
The line cannot sit on a property held by an LLC, corporation, partnership, or an irrevocable, blind, or land trust. Title has to be held by you individually or by a revocable living trust. This is the sharpest structural difference from a DSCR loan, which investors often hold in an LLC subject to program eligibility. A rental already deeded to an LLC needs a vesting change first, or a cash-out DSCR refinance instead.
Property types
The line allows single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones. It does not allow manufactured homes, co-ops, condotels, log homes, commercial or mixed-use properties, or agricultural zoning. Those property types are not offered. The DSCR side has its own exclusions: manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs.
Exposure and availability
A borrower is limited to three lines. Anyone owning more than 15 financed properties is not eligible. Some states bar a line on a property listed for sale, or listed within the past 60 days. HELOC availability through Lendmire is also narrower than its DSCR footprint. The line is available in 16 states, while DSCR investor loans cover 41 markets, including Washington, D.C.
Thin supply in the wider market
Investment-property HELOCs are a smaller niche than primary-home lines, and many large retail lenders decline them. That scarcity is a reason to go through a broker that shops multiple wholesale lenders instead of a single desk.
A fully borrowed down payment
This can work on some programs. But some purchase lenders require a minimum from your own funds. You also end up carrying two loans against one rent stream, so the cash-flow test gets harder.
Gift funds
A gift is not HELOC money. Most programs want an investment down payment to be your own capital, sourced and often seasoned.
Zero down
It does not exist on the target property. A line can cover the down payment, but the purchase loan still sets a leverage ceiling.
The Two-Payment Stress Test
Passing DSCR is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Your line payment sits outside it too.
Picture a rental with rent that clears the purchase loan’s payment at around 1.25x. On paper that looks comfortable. Now add the line. The rent was never asked to cover it, so that payment comes out of your pocket or your other income.
Then run three cases:
1. Base case: The unit is leased and both payments fit your budget.
2. Vacancy case: The unit sits empty for a stretch. The DSCR loan payment still comes due, and so does the line.
3. Step-up case: The draw period ends and repayment begins. The line’s payment usually rises, and pricing floats the whole way.
If case three breaks your budget, the plan is too tight. Real Estate Explained makes a similar point: without a clear payoff source, you have borrowed the down payment at a variable rate against property you already own. The seventh step, the exit plan, is what keeps that from happening.
Which Route Fits Which Investor?
No single route wins. Here is how the main funding paths compare.
| Route | Best Fit | Main Tradeoff |
|---|---|---|
| Line on primary residence | Equity-rich owner-occupant | Home secures investment debt |
| Line on an existing rental | Owner with rental equity | 70% CLTV cap, 700 credit |
| Cash-out DSCR on a rental | Investor with a seasoned rental | About 75% LTV max, seasoning |
| Savings-funded purchase | Cash-rich buyer | Ties up liquidity |
On the cash-out route, most programs top out around 75% LTV on a standard-rental cash-out, with about 6 months of seasoning as the common expectation.
Honestly, the cash-out refinance is often the cleaner choice when you own a rental with solid coverage. You get one loan instead of two, and the DSCR file already underwrites the rent. The line wins when you have equity in a primary residence and no seasoned rental. It also wins when you want cash on a schedule you control.
How to Judge a Program Without a Lender List
Because the best program depends on your situation, judge any option by these questions.
- Collateral fit. Does the line’s collateral match yours: primary, second home, or rental? Is title held individually or in a revocable trust?
- Credit fit. Does your score clear the occupancy tier you need? Investment lines start at 700.
- Leverage. What CLTV does your collateral allow, and how much cash does that release?
- Draw structure. Does the line require at least 75% drawn at closing? Does the repayment step-up fit your budget?
- Purchase lender acceptance. Does the DSCR lender accept borrowed funds for the down payment, closing costs, and reserves?
- Eligibility. Is the property type eligible, and is the state served?
A broker shops several wholesale lenders against those questions and matches the scenario to the program. That is the real answer to which program is best for you: the one that clears every question on this list.
Questions to ask before you draw
Ask the line lender how the draw minimum works and whether the property must be unlisted. Ask the DSCR lender whether borrowed funds count, whether any part must be unborrowed, and what reserves apply. Get the answers before you move money.
Frequently Asked Questions
Can a HELOC pay for the entire rental?
Usually not. The line supplies cash for the down payment, closing costs, and sometimes reserves. A separate purchase loan covers the rest. Some programs cap how much of the down payment can be borrowed, and a few want part of it from your own funds.
Does the HELOC payment lower my DSCR?
Typically not. The ratio compares rent to the new property’s PITIA only. The line payment stays outside it. It still comes out of your real cash flow, so run the two-payment stress test before you commit.
Is it better to put the line on my home or on a rental?
It depends on equity and credit. A primary-residence line can reach higher leverage, up to 90% CLTV at 720+ credit, but your home secures the debt. A rental-backed line caps at 70% CLTV with a 700 minimum, subject to lender guidelines.
Can I hold the rental in an LLC and still use a line on it?
No. Title on the line’s collateral has to be held by you individually or by a revocable living trust. The purchase side is different, since DSCR loans can often close in an LLC subject to lender program eligibility.
What if I do not have enough equity?
Look at a cash-out DSCR refinance on a seasoned rental, a savings-funded purchase, or a smaller or less leveraged deal. Each file is reviewed individually, and a larger down payment never erases credit floors or property eligibility.
