The Quick Read: The HELOC method means borrowing against equity in a property you already own, then using that cash as the down payment, closing costs, or rehab money on a rental you buy with separate financing. The two loans are approved separately and judged by different tests. The line is judged on you, and a DSCR loan is judged mainly on the property’s rent.
- A home equity line of credit (HELOC) is a revolving credit line secured by your property. It is not a down-payment program.
- Through Lendmire’s wholesale network, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit profile, subject to lender guidelines.
- The rental you buy is typically financed with a DSCR loan, which looks at whether rent covers the monthly housing payment.
- A line that sits on your own home puts that home behind your rental bet.
- Whether a DSCR program accepts borrowed funds as a down payment depends on the program, so confirm it before you draw.
What Is the HELOC Method?
The HELOC method is a sequence, not a product. You open a line against equity you already hold, draw cash, and put that cash into the next deal. Later you repay the line from rent, savings, or a refinance, and you can repeat the cycle.
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.
Investors use the phrase in a few ways. Some mean a down payment funded by a line on their primary home. Some mean a line on an existing rental. Others mean a buy-rehab-refinance loop, where the line pays for the purchase and the repairs. A smaller group means using a line to make lump-sum payments on a mortgage. This article covers the first three, because they involve buying more property.
The method does not replace the loan on the new property. It only changes where your cash comes from.
How Does a HELOC Actually Work?
A HELOC is an open-end line, meaning you can borrow, repay, and borrow again up to a limit. The CFPB’s plain-language explainer describes a draw period during which you can borrow, with 10 years given as an example. It also warns that falling behind could cost you the home that secures the line.
ConsumerAffairs reports that market-wide draw periods typically run about 5 to 10 years and can reach 15 with some lenders. It adds that payments usually rise once principal is included. It also notes that some lines adjust limits mid-draw if property value or credit changes.
The structures in Lendmire’s network are narrower than the market at large. An investment-property line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to a fixed payment. Those terms are subject to lender guidelines and full file review.
That 75% rule matters for the method. You cannot open a large line and leave it untouched for the right deal. Most of it is borrowed from the start, and you pay interest on it from day one.
How Much Can You Actually Pull?
Your usable line is the value of the property times the maximum CLTV, minus what you already owe. CLTV is the combined loan-to-value ratio, which adds every loan secured by the property and divides by its value.
Run it in percentages. Say you want a line on a rental, and your first mortgage equals 40% of its value. At the 70% investment ceiling, the most the line can add is 30% of the value. At least 75% of that, or about 22.5% of the value, would be drawn at closing. If your first mortgage already equals 60% of value, only 10% of value is left.
Credit decides which ceiling you get, and occupancy decides which table applies. Here is how the network’s ceilings compare by property use:
| Property use | Top CLTV | Credit needed | Max line at that CLTV |
|---|---|---|---|
| Investment property | 70% | 700 minimum | $500,000 |
| Second home | 90% | 720+ for 90% | $500,000 |
| Primary residence | 90% | 720+ for 90% | $500,000 |
The 90% figure exists only at a 720-or-better credit profile. On a primary residence, lines above $500,000 are available up to $750,000, but they cap at 75% CLTV and require a full appraisal. A line above $500,000 needs a 700 credit profile or better (720 on the longer-runway structure, the 5-year draw with a 25-year repayment). A lower credit score steps the ceiling down through the tiers, and the minimum credit profile on a primary residence is 600.
Lines at or below $500,000 ordinarily use an automated valuation, though a higher CLTV may call for a secondary valuation. Every line above $500,000 needs a full appraisal, and you can request one on any line.
Which Property Should Secure the Line?
Most of the capital in this method comes from one of two places: your primary residence or an existing rental. The difference is large.
A line on your primary residence reaches higher leverage, because primary-residence ceilings run up to 90% CLTV at 720+. It also carries the most personal risk. If the rental underperforms and you cannot cover the line, your home is the collateral.
A line on an existing rental is capped at 70% CLTV and $500,000, and it needs a 700 minimum credit profile. The risk stays on investment property instead of your residence. For many investors that is a better trade even though it unlocks less cash.
Two structural limits apply either way. The title must be held by you individually or by a revocable living trust. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on these lines. That is the sharpest difference from a DSCR loan, where an LLC can often be the borrower, subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change before it can secure a line, or a DSCR cash-out refinance instead. Lendmire’s piece HELOC For Real Estate Investing covers that choice in more depth.
The second limit is exposure. A borrower can hold three lines at most, and a borrower with more than 15 financed properties is not eligible.
How Does Underwriting Treat Each Loan?
The line and the new loan are two separate approvals, and each one asks a different question. Here is the sequence the way a file moves.
1. The line is approved on you. The lender reviews credit, debt-to-income, equity, and the property. DTI, or debt-to-income, can run to a 50% maximum, and it is 45% for profiles from 600 to 679. A ratio above 45% requires a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, so it assumes you borrow the whole line.
2. The credit report is checked. It uses a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing.
3. You draw the cash. The funds land in your account and carry the line’s payment obligation from day one.
4. The DSCR lender reviews the rental. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR is rent divided by the full monthly obligation: principal, interest, taxes, insurance, and any HOA dues.
5. The DSCR lender also reviews your funds. It looks at where the down payment came from and whether you have reserves. That is where a line gets tested.
The new line’s payment is a personal obligation that sits outside the rental’s coverage ratio. The ratio does not measure it. A lender may still look at your overall debt picture, so do not assume the line stays invisible.
What Does the DSCR Side Look Like?
On the purchase, most DSCR files across the network land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700+ credit score. Most programs want around a 660 score, and a 620 floor exists in parts of the network.
On 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. Reserves vary by lender, leverage, loan size, and transaction type, and they commonly sit around 6 months of PITIA, which is principal, interest, taxes, insurance, and association dues.
Here is the picture that makes the method click. Say your primary home carries a first mortgage equal to 50% of its value, and you qualify for 75% CLTV. That leaves a line up to 25% of the home’s value. If the rental you want costs about the same as the home, that line roughly matches a 25% down payment at 75% LTV. It does not cover closing costs or reserves, which come on top. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
That example is a model, not a quote. It shows why the method works best when your equity is large, when the rental’s rent covers its payment, and when you hold cash outside the line.
Clearing 1.00 is also not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. The Motley Fool makes a related point when it lists a HELOC as a purchase funding path. It warns there may be no cash flow until the line is repaid, so you have to run the numbers first.
Three Ways to Run the Method, and One Alternative
The same line can play different roles. The payoff source is what separates them. The last row is not a way to run the method at all. It is the alternative to compare against.
| Variation | How the line is used | Payoff source | Main risk |
|---|---|---|---|
| Down payment | Covers cash at closing | Rent and savings | Stacked payments |
| Rehab funding | Pays for repairs | Refinance | Low appraisal |
| Bridge | Funds a quick offer | Refinance or sale | Exit stalls |
| Alternative: cash-out compare | No line, one new loan | Rent over time | Larger new loan |
The first row is the plain version. The second is the buy-rehab-refinance loop, where you refinance the finished rental and retire the line. A refinance can only pay off a line if the finished property supports the loan you need, and an improvement may support a higher appraised value, depending on comps and underwriter review.
The last row is the alternative. If you already own a rental with equity, a DSCR cash-out refinance pulls the cash into a single new loan underwritten on rent. Across most of the network a cash-out tops out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation. Seasoning is the waiting period a lender wants after you buy a property before it will refinance. Lendmire’s piece Using HELOC To Invest In Real Estate goes further on that comparison. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Where Does the General Rule Break?
The general rule says to borrow the equity and put it into the next rental. These edge cases show where that rule fails.
The DSCR lender may not accept borrowed funds. Some programs allow a documented line draw as the down payment. Others want unborrowed cash or a minimum of your own funds. It is program-dependent, so ask before you open the line, not after.
Reserves and down payment are separate tests. Borrowed cash may cover the down payment while reserves still need to be verified in your own accounts. A file that is strong on down payment can still fall short on reserves.
The line itself may restrict renting. Terms on a line secured by your home can limit or prohibit renting that home out. That matters for house-hackers and for anyone converting a primary residence into a rental.
The lender can change the line mid-draw. If property value falls or your credit weakens, a lender may freeze or reduce the available balance. Plan as if the line might not be there when you want the second draw.
An LLC-owned property cannot secure the line. The title rule above is a hard stop, not a paperwork issue.
Some properties are not offered. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agriculturally zoned properties are not eligible for these lines. Manufactured homes, log homes, and barndominiums are also not offered under the network’s DSCR programs.
A conventional loan treats the line differently. On a debt-to-income purchase loan, a new line’s payment counts against you and can break an approval. DSCR files are tested mainly on property coverage instead.
Availability is narrower than the DSCR footprint. Lendmire arranges DSCR investor loans across 41 markets, including Washington, D.C. Home equity lines are offered only in its 16 full-service states.
What Happens When the Draw Period Ends?
This is the part many investors underestimate. During the interest-only draw, you pay only the interest on the balance. When repayment starts, principal joins the payment, so the monthly obligation steps up. The balance has not shrunk, so the bill rises. On an investment line that means year six brings a 25-year amortizing payment on whatever you still owe.
Pricing also floats through both periods and never converts to fixed, so the payment can rise for reasons that have nothing to do with the property. That is why the exit plan has to exist before the first draw.
Stress test the plan in three steps:
1. Assume the refinance or sale takes longer than you expect.
2. Assume the appraisal comes in below your target.
3. Assume the payment rises, and see whether rent and savings still cover both loans.
If the plan only works when everything goes right, the line is too large.
What Does the Decision Look Like in Practice?
The method fits when you hold large, stable equity, a strong credit profile, and a rental whose rent clears the coverage test with room to spare. It fits best when you have a plan to repay the line that does not depend on the rental appreciating.
It fits poorly in these situations:
- The line would sit on your primary home, and a vacancy would strain your household budget.
- Your coverage is thin, and a rent dip would pinch both loans at once.
- You are borrowing the entire down payment and have no cash of your own in the deal.
- Your title sits in an LLC, so you would have to restructure it just to open the line.
Many investors find the cleaner route is a DSCR cash-out refinance on a rental they already own, or a purchase with cash they saved. Others keep the line only as a short-term bridge. Which one is right depends on your equity, your credit profile, and how much of your own cash you can commit.

Frequently Asked Questions
Can I use a HELOC as the down payment on a DSCR loan?
Sometimes. Some DSCR programs accept a documented line draw, while others require unborrowed cash or a minimum of your own funds. The lender will want to see the source of the funds, and reserves are a separate requirement. Check the specific program before you draw.
Does the HELOC payment count in my DSCR?
Generally no. The DSCR ratio compares the rental’s income to its own monthly obligation, so your line’s payment sits outside the calculation. A lender can still review your overall debts, credit, and reserves, so the line is not invisible to the file.
What is the maximum CLTV on an investment-property line?
On an investment property, the network ceiling is 70% CLTV, with a 700 minimum credit profile and a $500,000 maximum line. There is no higher tier for investment lines. Primary residences and second homes reach 90% only at a 720-or-better credit profile.
Is a HELOC or a DSCR cash-out refinance better for pulling equity?
It depends on what you hold and how long you need the money. A line gives you revolving access but floats in price and puts your own equity behind it. A DSCR cash-out refinance is a single loan underwritten on rent, usually capped around 75% LTV on a standard rental with about 6 months of seasoning.
Can I open a line on a property held in an LLC?
No. These lines require title held by you individually or by a revocable living trust. A property already in an LLC needs a vesting change first, or a DSCR cash-out refinance as the alternative, subject to lender program eligibility.
