The Quick Read: A home equity line of credit (HELOC) supplies cash only; it never buys the rental itself. Investors draw on equity in a property they already own, then use that cash toward the down payment and closing costs on a separate purchase loan. Each loan is reviewed on its own terms, and both payments have to be carried.
- A HELOC is a revolving line secured by a property you own, usually your home.
- A separate purchase loan, often a DSCR loan, finances the rental.
- The line is typically variable-priced, so its payment can move.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV) and the line tops out at $500,000.
- Clearing a DSCR of 1.00 does not mean the deal cash flows once the HELOC payment is added.
Plenty of investors have equity sitting in a home and a rental in their sights. The two facts connect in an obvious way. The mechanics behind that connection are where deals succeed or stall, so this walks through them in order.
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.
What Is a HELOC, in Plain Terms?
A HELOC is a credit line secured by real estate you own. You borrow what you need, up to a limit, and pay interest on the drawn balance. It works like a credit card with a house behind it.
The CFPB’s consumer booklet on HELOCs notes that these lines typically carry variable rates, so monthly payments can change. It also describes a fixed draw period, with 10 years given as an example. When that period ends, you may be able to renew the line. If not, you can no longer borrow and a repayment period begins.
A market explainer from Opendoor describes a common structure of a 10-year draw with interest-only payments, then a 20-year repayment with principal and interest. That is a market-wide picture. The structure on this network is different and is covered below.
One more definition matters here. CLTV is combined loan-to-value: your first mortgage plus the line, divided by the property’s value. The usable line is roughly the value times the allowed CLTV, minus what you still owe on the first mortgage.
The Two-Loan Stack
The standard investor structure uses two loans. The first is the HELOC on a property you already own. The second is the purchase loan on the rental. The line funds the equity portion, and the purchase loan covers the rest.
Here is the sequence, step by step:
1. Choose the collateral. This is usually your primary home. It can also be an existing rental.
2. Size the line. The lender applies a maximum CLTV to the property’s value, then subtracts the first mortgage balance.
3. Qualify for the line. A HELOC is reviewed on you: credit, income, debt-to-income ratio (DTI), and equity.
4. Draw the cash. The funds move into your own account, creating a paper trail.
5. Close the purchase loan. That lender sets its own rules on leverage, credit, reserves, and borrowed funds.
6. Repay. Rent, a later refinance, or a sale pays down the line.
The line has to be open and drawn before you go to contract. A first-time investor with only a primary home has no rental to secure a line against, so the home is the collateral.
Which Property Secures the Line?
The answer shapes your risk more than anything else. A line on your primary home puts the home behind the debt. A line on an existing rental puts that rental behind it.
| Factor | Line on primary home | Line on an existing rental |
|---|---|---|
| Collateral at risk | Your residence | That rental |
| Network CLTV ceiling | 90% only at 720+ credit | 70% |
| Maximum line | Up to $750,000 | $500,000 |
| Draw structure | Two options | 5-year draw only |
Those figures reflect select wholesale lenders in Lendmire’s network, subject to lender guidelines and full file review. They differ from broader market surveys. One lender-adjacent guide reports market CLTVs of 80–85% on a primary home and 70–80% on an investment property. On this network, an investment line stops at 70% CLTV regardless.
How Lenders Treat an Investment-Property Line
Investment lines are tighter than home lines. Across the wholesale network, an investment-property line requires a 700 minimum credit score. Both the 700 and 720 tiers reach the same 70% CLTV, so a higher score buys eligibility rather than extra leverage. Because the line caps at $500,000, it normally runs on an automated valuation and often closes without a traditional appraisal. A borrower can still request a full appraisal.
Other points worth knowing:
- Line size. Lines run from $25,000 to $750,000, but anything above $500,000 is for primary residences only.
- DTI. The maximum is 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw.
- Draw at closing. At least 75% of the line is drawn at closing.
- Pricing. It floats through both the draw and repayment periods and never converts to fixed.
- Property types. Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure-family history on investment files follows a path of 7 years for a foreclosure and 4 for a deed-in-lieu, pre-foreclosure, or short sale.
The Draw Structure on This Network
Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year repayment. The other has a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year draw and 25-year repayment structure only.
Either way, the payment can change in two ways. It can rise because pricing floats. It can also jump when the draw ends and principal payments begin. Plan for it before you draw, not after.
How the Purchase Loan Sees the HELOC
The purchase lender reads the property; the HELOC lender reads you. That split is the center of this strategy.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The DSCR is monthly rent divided by the new property’s monthly principal, interest, taxes, insurance, and any association dues (PITIA). Your HELOC payment is generally not in that ratio. Treatment varies by lender, so confirm it against the actual program.
A conventional investor loan is different. It looks at your DTI, so the HELOC payment counts against you. For more on how the two paths differ, see the complete DSCR loans guide.
On a DSCR purchase, most files land at 75%-80% LTV, meaning 20%-25% down. Select high-leverage programs reach 85% LTV with roughly a 700+ score. Credit floors start at 620 in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. On the coverage side, a DSCR of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
Where the General Rule Breaks
Several edge cases change how a HELOC is treated as a down payment source.
Borrowed funds are not treated uniformly. Some programs accept them for the down payment with documentation. Others resist them. Because acceptance varies by program, ask the purchase lender in writing before you draw.
Reserves may not accept borrowed money. Reserves are the months of payments you hold in the bank after closing. They commonly run around 6 months of PITIA, and they vary by lender, leverage, loan size, and transaction type. A HELOC may cover the down payment but not the cushion. Confirm which bucket the draw can fill.
You cannot borrow the whole purchase. The purchase loan’s leverage cap sets a floor on your cash in, no matter how large the line is.
LLC title blocks the line. A HELOC on this network must be held by an individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
Exposure caps apply. 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. Owning more than 15 financed properties makes a borrower ineligible.
Listed properties. A property that is listed for sale, or was listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
Availability is narrower than DSCR. HELOCs through Lendmire are available only in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. Lendmire’s DSCR loans cover 41 markets, including Washington, D.C.
Key Terms Defined
HELOC: A revolving credit line secured by real estate, with a draw period followed by repayment.
CLTV: The first mortgage plus the line, divided by the property’s value.
DSCR: Monthly rent divided by the property’s monthly PITIA, a ratio the lender uses to judge whether rent covers the payment.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly housing cost.
Reserves: Liquid funds a lender wants left after closing.
Seasoning: A waiting period a lender wants between two events.
Stress-Test Before You Draw
Passing the DSCR test does not mean the deal makes money. Rent covering the purchase loan’s PITIA says nothing about repairs, vacancy, management, utilities, or capital expenses. It also ignores your HELOC payment. Your bank account does not ignore it.
Run the plan in three passes:
- Base case. Take rent, subtract the purchase loan payment and the HELOC payment, then subtract the real costs of owning.
- Rate-up case. The line floats, so assume its payment rises with no new draws. The CFPB booklet notes payments can change even when you borrow nothing more.
- Empty case. Assume the rental sits vacant for a stretch while both loans stay due.
Then test the end of the draw period, when a payment of interest only becomes principal plus interest. A rental that cannot carry that payment needs a refinance or a payoff plan on day one.
Picture an investor who uses a line to put 25% down on a rental that clears about 1.2x coverage. The ratio looks comfortable on paper. Add the HELOC payment and a vacant month, and the real cushion can disappear. That gap is why reserves outside the line matter. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Exit plans deserve the same attention. Typical exits are paying down the line from cash flow, refinancing the new property, or selling. Some investors find a HELOC suits a short hold better than a long one. If you plan to refinance soon, check the new loan for a prepayment penalty, which is a fee for paying off early.
The Risks, Plainly
A home-secured line puts your home behind the debt. Missed payments can lead to foreclosure on the home, not the rental. If the rental sits empty, both loans remain due.
Two properties carrying leverage also make a vacancy plus a job loss the real worst case. Keep rental reserves and personal liquidity separate from the line. Set a maximum draw you can carry if rent stops.
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.
HELOC or Something Else?
A line is one of several ways to source equity. Compare it against the alternatives before you commit.
| Option | Payment type | Best fit |
|---|---|---|
| HELOC | Floats, interest-only draw | Staged or uncertain cash needs |
| Fixed home equity loan | Set payment | One lump sum, predictable cost |
| DSCR cash-out refinance | Set by new loan | Equity in an existing rental |
| Cash savings | None | Lowest added debt |
A DSCR cash-out refinance on an existing rental taps its equity through a new loan on that property. Cash-out tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. Lendmire’s piece Top Bank Statement HELOC Providers for Investment Purchases goes deeper on one version of the line. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Questions to Ask Before You Apply
- Does the purchase lender accept HELOC funds for the down payment, closing costs, or reserves?
- Is the line secured by my home or by a rental?
- What is my combined leverage after the draw?
- When does the draw period end, and what does the payment do then?
- Is the property titled in my name or in an LLC?
- Does my state fall within the available states?
Frequently Asked Questions
Can a HELOC pay for an entire investment property?
Not on this network’s programs. A HELOC provides cash, and the purchase loan sets a minimum down payment through its leverage cap. Most DSCR purchases land at 75%-80% LTV, so you need real cash in, subject to lender guidelines.
Does the HELOC payment count in my DSCR?
Generally no. The ratio is rent divided by the new property’s PITIA. Lender treatment varies, and your own cash flow still bears the payment, so test the deal after both loans.
Is the HELOC rate fixed?
No. Pricing floats through both the draw and repayment periods on this network and never converts to fixed. The CFPB also notes that home equity lines typically carry variable rates.
Can I get a HELOC on a rental property?
Yes, within limits. On this network an investment line requires a 700 minimum credit score, caps at 70% CLTV, and tops out at $500,000. It must be held in your name or a revocable living trust, not an LLC.
Is HELOC interest tax deductible when I buy a rental?
It can depend on how the funds are used. The IRS explains in Publication 936 that home mortgage interest treatment on equity lines applies to buying, building, or improving the home that secures the loan. Rental use is treated differently, so speak with a qualified tax professional.
