The Quick Read: An investment property HELOC can supply the down payment on the next rental, but it is a separate loan with its own approval, and the purchase lender decides whether borrowed money counts toward the down payment, closing costs, or reserves, so the plan only works when both approvals line up. The line is secured by a property the investor already owns. A DSCR purchase loan then finances the new rental on its own rent.
- On an investment property, the network’s equity line tops out at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
- Pricing on the line floats for the whole life of the loan and never converts to fixed.
- At least 75% of the line is drawn at closing, so interest starts on most of it right away.
- The new rental’s DSCR is built from its own rent and its own payment, not from the line.
- Borrowed down-payment funds are program-dependent. Confirm acceptance with the purchase lender before opening the line.
How an Investment Property HELOC Covers the Down Payment
The strategy is two loans, two approvals, and two payments. The first loan is the equity line, which turns home equity into cash. The second is the purchase loan on the new rental, which for most investors is a DSCR loan. DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines. They are business-purpose loans for non-owner-occupied investment property, so they are reviewed differently from a standard owner-occupied mortgage.
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.
The two loans never merge. The line lender cares about the collateral, the borrower’s credit, and combined leverage on the property securing the line. The purchase lender cares about the new property’s rent, the borrower’s credit and reserves, and where the cash to close came from. Approval on one says nothing about the other. Drawing the cash first and asking the purchase lender second is a risky order, because the purchase lender may not accept the funds.
For the full picture of the purchase side, Lendmire’s complete DSCR loans guide walks through how the loan itself is built.
Key Terms Defined
HELOC: A revolving line of credit secured by a property you own, drawn in stages instead of one lump sum.
CLTV (combined loan-to-value): All liens on a property added together and divided by its value.
Draw period: The stretch of the line when you can borrow and typically pay interest only.
Repayment period: The later stretch when the balance fully amortizes and the payment steps up.
DSCR: Monthly rent divided by the monthly principal, interest, taxes, insurance, and any HOA dues on the property.
Seasoning of funds: How long money has sat in the borrower’s account before a lender treats it as the borrower’s own.
Reserves: Liquid funds the borrower holds after closing, measured in months of the property’s payment.
What a HELOC Is Mechanically
A home equity line works like a credit card secured by real estate. The Consumer Financial Protection Bureau explains that you can generally spend up to your credit limit at any point during the draw period, and gives a draw period of 10 years as an example. It also notes that these lines usually carry a variable interest rate, so payments can change from month to month. Some plans require a minimum amount each time you borrow, or an initial draw when the line opens.
The agency’s HELOC booklet adds that variable-rate payments can move even when you draw nothing more, and that the repayment period begins when the draw period ends. Both points matter later here, because the payment on the line is the second obligation the investor carries.
Rental collateral is the harder version of this product. Experian says a HELOC on a rental is possible but usually harder to qualify for than one on a primary home, and less common. It also reports that lenders across the broader market commonly cap investment-property lines near 80% of value. On the network Lendmire brokers through, the investment-property ceiling is lower, at 70% CLTV.
Step by Step: How the Plan Moves Through Underwriting
Here is the sequence, in the order the files actually move.
1. Pick the collateral. The line can sit on a primary residence or an existing rental. A primary-home line puts the residence behind the new rental purchase. A rental-secured line keeps the risk inside the investment portfolio but runs on tighter terms.
2. Size the line against combined leverage. The line lender adds the first mortgage, if any, to the new line and tests the total against the property’s value. On an investment property, that total cannot exceed 70% CLTV.
3. Qualify the borrower. The network’s investment line wants a 700 minimum credit score and a debt-to-income ratio no higher than 50%. The line is qualified on the interest-only payment calculated at the maximum draw, not on what is drawn at closing.
4. Value the property. Because an investment line caps at $500,000, it normally runs on an automated valuation with no traditional appraisal. A borrower can still request a full appraisal.
5. Draw and document. At least 75% of the line is drawn at closing. The cash lands in the borrower’s account, and the purchase lender will want the line statement and the bank statement showing the deposit.
6. Qualify the purchase. The DSCR lender tests the new rental’s rent against that property’s own payment, then reviews credit, reserves, and the source of the cash to close.
7. Plan the exit. The line gets repaid from savings, portfolio cash flow, or a later refinance of the rental.
Network Terms for an Investment Line
The numbers below are the typical eligibility ranges across select wholesale partners. They are guidance, not commitments, and every file is reviewed individually by the lender.
- Maximum CLTV: 70% on an investment property. Both the 720+ and 700+ credit tiers reach 70%, so a higher score buys eligibility, not extra leverage.
- Credit floor: 700 for investment collateral, with no tier beneath it.
- Line size: $25,000 to $500,000 on an investment property. Lines above $500,000 are available only on primary residences.
- Structure: a standalone line in first or second lien position. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
- Pricing: floats through both the draw and the repayment period and never converts to fixed.
- Minimum draw at closing: at least 75% of the line.
- Eligible property: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
- Title: held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
- Exposure: a borrower can hold up to three lines, and an owner of more than 15 financed properties is not eligible.
- Availability: 16 states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That is narrower than Lendmire’s DSCR footprint of 41 markets, including Washington, D.C.
On a primary residence, the line’s ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. That tier does not apply to investment collateral, so an investor who wants more leverage from a primary home is making a different risk choice, not finding a better rental line.
How the Purchase Lender Treats Borrowed Funds
This is the step most investors skip. The HELOC lender does not care what you do with the cash. The purchase lender does, and its answer varies by program.
Some DSCR programs accept borrowed funds for the down payment with documentation. Others cap the borrowed share or want some seasoned, unborrowed cash in the file. A few lenders in the network are comfortable with a line draw if the statements trace cleanly. The strictest overlays are the ones that read a fully borrowed down payment as financing close to the whole price.
A BiggerPockets investor discussion shows the friction from the conventional side, where one bank would not allow a HELOC as a down payment. Whether a DSCR lender allows it is a rule that belongs to each lender.
The documents that usually answer the lender’s questions are:
- The line agreement and the statement showing the draw.
- The bank statement showing the deposit into the borrower’s own account.
- A clear paper trail from the draw to the closing funds.
- Proof of reserves held separately from the borrowed funds.
Down payment and reserves are separate tests. Borrowed funds are often accepted for the first and excluded from the second. Reserves on DSCR files vary by lender, leverage, loan size, and transaction type. They commonly run around six months of the property’s payment. 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 nine months.
On the purchase itself, most files land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700-plus score. The down payment is only part of the cash needed. Closing costs and reserves need their own funding, and the line has to be sized with all three in mind.
Funding Mix and Loan Comparison
The first table compares the four common ways to fund the down payment. The second shows what changes as the share of borrowed money grows.
| Source | Collateral | Payment shape | Main catch |
|---|---|---|---|
| Savings | None | None | Ties up cash |
| HELOC | Owned property | Floats, interest-only draw | Second payment |
| Fixed home equity loan | Owned property | Fixed second lien | Lump sum only |
| Cash-out refinance | Existing rental | New first mortgage | Resets the first lien |
| Funding mix | Equity in new deal | Payment stack | Cushion in a downturn |
|---|---|---|---|
| All savings | Full down payment | One loan | Widest |
| Partial HELOC | Reduced | Two loans | Moderate |
| Fully borrowed | Near zero | Two loans | Thinnest |
On the cash-out side, the network’s refinance tops out around 75% LTV, with about six months of seasoning as the common expectation. That is why a refinance often replaces the line once the new rental has some time behind it.
A Worked Example in Ratios
Run the numbers on an investor who owns a rental with a first mortgage equal to 45% of its value. An investment line allows 70% combined, so the room for a new line is 25% of that property’s value. Say the next rental costs about what the first one is worth. A purchase at 75% LTV needs 25% down, so the line, drawn at roughly its full size, covers the down payment and nothing else. Closing costs and reserves still need other money. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Now the second half. Suppose the new rental’s rent clears a coverage ratio around 1.2x against its own payment. But the line is drawn at least 75% at closing, and it carries its own interest-only payment on the old property. That payment comes from somewhere else: the first rental’s income, the investor’s wages, or both.
The DSCR ratio does not see this. It compares rent to PITIA on the new property and stops. Clearing 1.00 does not mean the deal cash flows, because repairs, vacancy, management, utilities, and capex sit outside the calculation. A file at 1.2x with a borrowed down payment can still lose money every month after the line payment.
A word on the coverage floor. A 1.00 ratio is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Neither path makes the line payment disappear.
Where the General Rule Breaks
The fully borrowed down payment. Some DSCR programs accept it. Others cap the borrowed share. The effective leverage on the deal approaches the full price, and the investor has little equity if values soften. The honest answer is program-dependent.
Title held in an LLC. The line cannot be written on a property titled in an LLC. A property already deeded to an LLC needs a vesting change before the line can close, or the investor can use a DSCR cash-out refinance instead. The DSCR purchase can close in an LLC, subject to lender program eligibility.
A line above $500,000. An investment line cannot be larger than $500,000. Any line above that size is primary-residence only, requires a 700 or better credit profile (720 on the longer-runway structure), and needs a full appraisal. Its ceiling is 75% CLTV, which is separate from the investment ceiling of 70% CLTV.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible for the line in NC, PA, TN, TX, and WA.
Portfolio size and line count. An investor with more than 15 financed properties is not eligible, and a borrower is limited to three lines. A growing portfolio can hit those walls.
Gift funds versus line proceeds. The two are underwritten differently. Gift funds come from a third party. Line proceeds are the borrower’s own borrowing, secured by an asset, which is why some lenders treat them as borrowed capital instead of savings.
Floating pricing. The line never converts to fixed. The CFPB notes that variable-rate payments can change even when nothing more is drawn, and the payment steps up again when the draw period ends. A cash flow plan that only works at today’s payment is a thin plan.
Tax treatment. 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 Decision Looks Like
The strongest files clear two tests at once: enough equity to open the line, and enough rental coverage on the new property. Before opening a line, run through this checklist.
- Does the collateral property fit the network’s terms, meaning an eligible property type and title in an individual’s name or a revocable trust?
- Is combined leverage at or below 70% CLTV, with a 700-plus credit score?
- Does the purchase lender accept borrowed funds, and for how much of the down payment?
- Are closing costs and reserves funded separately from the line?
- Does the new rental cover its own payment with room to spare after vacancy and repairs?
- Can the investor carry the line payment from outside the new property, including a stress case where pricing moves up?
- Is there an exit, such as a refinance or savings plan, before the repayment period begins?
If two or more of those answers are no, a smaller line or a larger share of savings is the safer structure. If every answer is yes, the line is a reasonable tool for a growing portfolio. A larger down payment also lowers the new loan’s monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Frequently Asked Questions
Can a HELOC be used as the down payment on a rental?
Usually yes on DSCR files, but it depends on the purchase lender. Some programs accept borrowed funds with documentation, and others cap the borrowed share or ask for some seasoned cash. Ask the purchase lender before opening the line.
Does the HELOC payment count in the DSCR?
On most DSCR files, the ratio is built from the new property’s rent against its own payment, so the line payment generally stays out of it. That is the typical treatment, and the lender can still look at the payment when reviewing the borrower. On a loan based on personal debt-to-income, the line payment is a debt and can break the ratio.
How much can I borrow against a rental property?
On an investment property, the network’s line goes up to 70% CLTV and $500,000, with a 700 minimum credit score. Market surveys report that lenders more broadly commonly cap investment-property lines near 80%, but that is not the network figure.
Can the line cover reserves too?
Often no. Down payment and reserves are separate tests, and borrowed funds are commonly excluded from reserves. Reserves vary by lender, leverage, and loan size, and commonly run around six months of the property’s payment.
Can I take the line against a property held in an LLC?
No. The network requires title in an individual’s name or a revocable living trust. A property already in an LLC needs a vesting change first, or the investor can use a DSCR cash-out refinance instead.
