The Quick Read: A home equity line of credit (HELOC) lets you borrow against equity you already own, and many investors use it to fund the down payment on a rental. Two separate loans are involved. The line is underwritten on you and the property that secures it, while a DSCR purchase loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV) with a 700 minimum credit score and a $500,000 line cap.
- On a primary residence, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile.
- The HELOC payment is generally not part of the new rental’s coverage ratio, but you still pay it from your own pocket.
- A DSCR above 1.00 does not mean the rental cash-flows. Repairs, vacancy, and management sit outside the calculation.
- Most home equity lines on the network are variable and never convert to fixed.
What Is a HELOC Loan and How Does It Work?
A HELOC is a revolving line of credit secured by your property. You borrow what you need up to a limit, repay it, and borrow again during a set window. It behaves more like a credit card than a standard mortgage, but a lien on your property backs it.
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.
Every line has two phases, and the federal consumer-finance regulator booklet on HELOCs describes both. The draw period is when you can borrow. The repayment period begins when the draw period ends. Some plans allow interest-only payments during the draw, which means nothing goes toward principal. When repayment begins, the lender may set a schedule to repay the balance, or it may require the whole balance at once. If the rate is variable, your payment can change even when you borrow nothing new.
Investors care about the gap between those two phases. A low draw-period payment feels easy. Then the payment steps up when principal starts to amortize. Plan for that step on day one.
How Does Using a HELOC Loan to Invest Fit Together?
The HELOC and the investment purchase are two separate underwriting events. Treat them that way and most of the confusion disappears.
Event one: the HELOC. The lender looks at you. It reviews credit, income, debt-to-income (DTI), the equity in the collateral property, and existing liens. The new line payment lands in your personal debt picture. On the network, the HELOC payment is qualified as interest-only on the maximum draw, which is a conservative test.
Event two: the DSCR purchase loan. The debt service coverage ratio (DSCR) divides the rent by the full monthly housing obligation on the new property. That obligation is principal, interest, taxes, insurance, and any association dues. The ratio measures the deal, not your paycheck. The HELOC payment is generally not in that ratio, though a lender may still review your overall debt picture.
This pairing works for a reason. A conventional loan would stack the HELOC payment and the new mortgage on top of your DTI. A DSCR loan avoids much of that stacking. It also suits self-employed investors, because write-offs that shrink taxable income do not set the rental loan’s coverage test.
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 Lendmire complete DSCR loans guide walks through that framework in full.
Step by Step: From Line to Closing
Here is how the sequence runs in practice.
1. Pick the collateral. Most investors borrow against their primary home. A line against an existing rental is possible, but the ceilings are tighter and the credit floor is higher.
2. Work out the CLTV. Add every lien on the property, including the first mortgage and the new line. Divide by the property’s value. That percentage must fit under the ceiling for your credit tier and occupancy.
3. Qualify yourself. Expect a review of credit, DTI, and the property. The credit report cannot be more than 90 days old at closing, and no rescores are allowed.
4. Draw the funds. At least 75% of the line is drawn at closing on the programs we place files with. That is a firm rule, so size the line to what you will actually use.
5. Document the money trail. Keep the HELOC statement, the deposit into your account, and the wire to title. A lender buying a rental wants to see where the down payment came from.
6. Underwrite the rental. Rent must cover the new property’s payment at the coverage level the program requires.
7. Close and carry both payments. The rent carries the new mortgage. You service the HELOC separately.
8. Plan for the end of the draw. Know the date when interest-only ends and amortization starts.
Whether borrowed funds can count toward the down payment, toward reserves, or both depends on the lender and program. That is a question to settle before you open the line.
What Do the HELOC Parameters Look Like by Occupancy?
The ceiling depends first on how the collateral property is used. Do not borrow a primary-residence figure and apply it to a rental.
| Collateral | Minimum credit | Ceiling | Max line |
|---|---|---|---|
| Primary residence | 600 | Up to 90% CLTV (720+ only) | $750,000 |
| Second home | 640 | Up to 90% CLTV (720+ only) | $500,000 |
| Investment property | 700 | 70% CLTV | $500,000 |
These are typical ranges from select wholesale lenders, subject to lender guidelines and full file review. Several details sit under the table.
- Primary residence tiers. A 600 profile’s CLTV ceiling varies by scenario. A 640 profile reaches 80%. Profiles from 660 to 719 reach 85%, with lines up to $500,000. The 90% tier requires 720 or better.
- Second homes. A 640 profile reaches 75% CLTV. 660 reaches 80%. 680 to 719 reaches 85%. 720 or better reaches 90%.
- Investment property. Credit at 700 or higher is the entry point, and 70% CLTV is the ceiling. No tier sits above it.
- Large lines. Lines above $500,000 exist only on primary residences, cap at 75% CLTV, and need a full appraisal.
- Line size. Lines run from $25,000 to $750,000, with a $1,000 minimum for each draw after closing on the program that states one.
- DTI. The maximum is 50%, and it drops to 45% for credit profiles from 600 to 679.
- Valuation. Lines at or below $500,000 ordinarily use an automated valuation. A full appraisal is required above that size, and you can request one anyway.
To see how this works, say your first mortgage equals 50% of the home’s value and the home is your primary residence. At a 75% CLTV ceiling, the line could reach up to 25% of value, subject to the line cap and your credit tier. Run the same home as an investment property and the ceiling is 70%, so the room shrinks to 20% of value.
Lendmire arranges these lines in its 16 full-service states. That is narrower than its DSCR footprint of 41 markets, including Washington, D.C.
What Structures Exist?
Several variations change the risk profile more than the headline CLTV does.
Lien position. The line can sit in first or second position. Most investors keep an existing first mortgage and add the line behind it. If your first loan is attractive, a HELOC preserves it. If it is not, a DSCR cash-out refinance may replace the first loan instead.
Draw structures. On primary residences and second homes, two structures exist. One is a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other is a 5-year interest-only draw followed by a 25-year repayment. Investment lines use the 5-year draw and 25-year repayment structure only. Pricing floats during both phases and never converts to fixed. A longer draw feels gentler. The balance still has to be repaid.
Closed-end second. This is a single fixed draw instead of a revolving line. It can suit an investor who knows the exact cash needed. For the line-versus-refinance choice, see Lendmire’s piece Using HELOC To Invest In Real Estate.
DSCR purchase terms. Most DSCR purchase files land at 75% to 80% LTV on a purchase. Select programs reach 85% LTV with roughly a 700 or higher score. Coverage of 1.00 is where many select programs start. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. A larger down payment can lift coverage. It never removes leverage caps, credit floors, reserve rules, or property eligibility. Reserves vary by lender, leverage, loan size, and transaction type, and commonly sit around 6 months of principal, interest, taxes, insurance, and dues (PITIA).
Where the General Rule Breaks
A few situations catch investors who learned the basics and stopped.
Borrowed down payment means near-full financing. If the line funds the down payment, your combined leverage on the purchase approaches the full price. A modest price drop can leave you owing more than the property is worth. The HELOC rides on your home, so that shortfall is not limited to the rental.
Down payment versus reserves. A lender may accept line proceeds for one and not the other. Ask early, because a file that is fine on coverage can still stall on reserves.
Payment shock. The step from interest-only to amortizing can be large, and the CFPB booklet warns that some plans demand the full balance at once. Because pricing floats on these lines, a rising index raises the payment on top of that step. We cannot predict the size of the shock. We can say it should be in your plan before you draw.
LLC titling. A HELOC property must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
Ineligible property types. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural property are not offered. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Some programs have additional limits, such as a 640 minimum on 2-4 units.
Exposure caps. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on one program and $750,000 on another. A borrower with more than 15 financed properties is not eligible.
Debt history. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure-family history splits. One program seasons a foreclosure in seven years and a deed-in-lieu, pre-foreclosure, or short sale in four. The other declines that history regardless of age.
Stock-market use. Some investors borrow against home equity to buy securities instead of property. That swaps rental income for market volatility, and the payment continues when prices fall. Lendmire covers the trade-offs in its piece Using HELOC To Invest In Stocks. The collateral risk is identical: your home backs an asset that can lose value.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction. (IRS Publication 936 covers home-secured debt.)
Is a HELOC Loan Right for Your Next Purchase?
Use this checklist.
- Equity. Your CLTV fits under the ceiling for your credit tier and occupancy, with room to spare.
- Credit. You meet the credit floor for the collateral. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review.
- Income stability. You can service the HELOC if the rental sits vacant for a stretch.
- Coverage. The rental clears the DSCR the program requires, and you have checked cash flow after repairs, vacancy, and management.
- Reserves. You have liquid reserves beyond the draw itself.
- Title. The collateral is in your name or a revocable trust.
- Exit plan. You know how the line gets repaid if rents fall or prices dip.
Walk away if the plan depends on every number going right. A HELOC draw plus a DSCR purchase means two debts and one rent check. Clearing 1.00 is not positive cash flow, because the ratio only compares rent to PITIA.
If the numbers pass, size the draw to the purchase and nothing more. Keep a cushion for the step-up in payment. Keep the paper trail clean.
Key Terms Defined
Combined loan-to-value (CLTV). All liens on a property added together, divided by the property’s value.
Draw period. The window when you can borrow from the line, often with interest-only payments.
Repayment period. The phase after the draw ends, when principal must be paid down.
PITIA. Principal, interest, taxes, insurance, and association dues, the full monthly housing obligation that DSCR compares to rent.
Balloon payment. A lump sum due at the end of a term instead of gradual repayment.
Lien position. Where a loan stands in line for repayment: first or second behind another mortgage.
Frequently Asked Questions
Can I use a HELOC loan for the down payment on a rental property?
Many investors do. The line is underwritten on you and the collateral, and the DSCR loan is underwritten on the rental. The lender on the purchase will want the draw traced from the line to your account to title. Whether it counts toward reserves as well depends on the lender and program.
Does the HELOC payment lower my DSCR on the new rental?
Generally not. DSCR compares the new property’s rent to its own PITIA. The HELOC payment still comes out of your pocket, and a lender may still review your overall debt picture.
What is the maximum CLTV on a HELOC secured by a rental?
On an investment property, the ceiling is 70% CLTV with a 700 minimum credit score and a $500,000 line cap. The 90% ceiling applies only to primary residences and second homes, and only at a 720-or-better credit profile.
Can an LLC own the property that secures the line?
No. Title must be in your name or in a revocable living trust. A property already in an LLC needs a vesting change or a DSCR cash-out instead.
What happens when the draw period ends?
Repayment begins. On the network, that means a fully amortizing payment over 17 or 25 years, depending on the structure, and pricing stays variable. Your payment can rise sharply, so build that step into your plan.
