The Quick Read: A home equity line of credit does not buy the rental; it supplies cash, usually drawn against your primary home, for the down payment while a separate DSCR (debt service coverage ratio) loan finances the property, and it works when the purchase lender accepts borrowed funds and the rent can carry both payments.
- The line is underwritten on you: credit, debt-to-income, and the equity in the home that secures it. The DSCR loan is underwritten on the rental’s rent against its payment.
- You can’t open a line on the rental you’re about to buy. The line has to be open and funded before you go under contract.
- Across Lendmire’s wholesale network, a line secured by an investment property tops out at 70% combined loan-to-value (CLTV, every lien on the property added together) with a 700 minimum credit score and a $500,000 maximum line.
- A line on a primary home can reach 90% CLTV, but only at a 720-or-better credit profile.
- Ask the purchase lender how it treats borrowed funds before you draw a dollar. That one call decides whether the plan works.
Key Terms Defined
Draw period: the window when you can borrow from the line and, on the programs described here, pay interest only.
Repayment period: the stretch after the draw period, when the balance amortizes and every payment includes principal.
PITIA: principal, interest, taxes, insurance, and association dues. It’s the full monthly payment on the rental, and it’s the bottom half of the coverage ratio.
Reserves: liquid money left over after closing. Lenders want proof you can carry the property if a month goes wrong.
Seasoning: the waiting period a lender wants between two events, such as buying a property and refinancing it, or funds landing in your account and being used.
Vesting: how title is held. For a home equity line, that means you personally or your revocable living trust.
Automated valuation: a computer estimate of value used instead of a full appraisal on smaller lines.
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 a HELOC Actually Does in a Purchase
A HELOC is a revolving credit line secured by property you already own. You borrow what you need, when you need it, up to the limit. In a purchase, it’s a source of cash. The purchase loan is a separate file with a separate lender.
“Local” here means you own equity in property near you and want to use it to buy the next rental. It doesn’t mean crowdfunding, community investing, or finding outside partners. This article is about your own equity.
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 loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal debt-to-income ratio is not the test.
The HELOC is the opposite. NerdWallet notes that not every lender offers a line against an investment property, qualification is strict, and you usually can’t borrow as much as you could against a primary home. That’s why most investors pull the cash from their own residence instead. It also explains why the two loans end up with different underwriters asking different questions.
Which Property Do You Borrow Against?
You have two collateral choices, and they behave very differently. A line on your primary home has the widest lender pool and the highest leverage. A line on an existing rental has a smaller pool, tighter leverage, and puts the rental at risk instead of your residence.
| Factor | Line on Primary Home | Line on a Rental |
|---|---|---|
| Max CLTV (network) | Up to 90%, only at 720+ | 70% |
| Minimum credit | 600 program floor | 700, hard floor |
| Max line | $750,000 | $500,000 |
| Draw structure | 3-yr or 5-yr interest-only | 5-yr draw, 25-yr repayment |
| Asset at risk | Your residence | The rental |
Market-wide figures run higher on paper. NerdWallet reports an 80% maximum loan-to-value on investment-property lines, though many lenders sit below 70%. The network figure is 70% CLTV. Credit above 700 buys eligibility on an investment line, not extra leverage, because 720 and 700 both reach the same 70% ceiling.
A line on a primary home steps its ceiling down as credit drops. The 90% tier exists only at 720 or better, so don’t plan around it unless your score is there. Primary lines above $500,000 need a 700 credit profile or better (720 on the five-year-draw structure), cap at 75% CLTV, and require a full appraisal.
One practical point: because an investment line caps at $500,000, it sits in the automated-valuation lane and commonly closes with no traditional appraisal. Lines at or below $500,000 on any occupancy ordinarily run the same way, though a higher CLTV may trigger a second valuation. You can also request a full appraisal in any case.
Sequencing the Deal for Local Investors Funding a Purchase
Underwriting happens in a set order, and getting the order wrong is how deals stall. Here’s the sequence start to finish.
1. Check the equity. The standard sizing method takes a percentage of appraised value and subtracts what you owe. The CFPB’s HELOC booklet shows the method with a $100,000 home, a 75% cap, and a $40,000 balance, which leaves a $35,000 line. On an investment-collateral line, swap in the 70% CLTV cap. Only the collateral property’s equity counts.
2. Get approved on your own profile. The HELOC lender looks at credit, debt-to-income, existing liens, and value. Debt-to-income tops out at 50%, and the payment is figured on interest only at the maximum draw. Size the line to your need, not your ceiling.
3. Open and fund the line before you go under contract. Draw the cash into your own account. The paper trail starts there.
4. Call the purchase lender before you draw. Treatment of borrowed funds varies by lender. Some accept documented HELOC proceeds as the down payment. Some cap the borrowed share. Some want a slice of your own seasoned, unborrowed cash.
5. Assemble the file. Expect to show the HELOC closing documents, the draw confirmation, and statements with the cash landing in your account. The new line will also appear on your credit report. Large unexplained deposits create conditions.
6. Close the DSCR loan on the rental’s numbers. The coverage ratio is monthly rent divided by PITIA. The HELOC payment normally sits outside that ratio.
Step 6 deserves one more look. “Outside the ratio” is not the same as “outside your life.” The HELOC payment is a real monthly obligation, and you still have to cover it.
What the Purchase Lender Looks At
Across Lendmire’s wholesale network, most purchase files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV (15% down) with roughly a 700-plus score. Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders on standard programs, subject to lender guidelines.
On credit, a 620 floor exists in parts of the network, most programs want around 660, and 700-plus unlocks the strongest leverage tiers. Reserves vary by lender, leverage, loan size, and transaction type. About six months of PITIA is common, conservative files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up toward nine months.
Here’s the part HELOC borrowers miss. Down payment, closing costs, and reserves are tested separately. Borrowed money may count toward the first and not the others. A lender that welcomes your HELOC proceeds as down payment may still want reserves in your own unborrowed funds.
Coverage works the same way. 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. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
A bigger down payment can lift the ratio by shrinking the loan. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
DSCR eligibility also carries property limits. Manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs.
Where the General Rule Breaks
An LLC can’t hold the line. This is the sharpest difference from a DSCR loan. Home equity lines require title in your own name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts can’t hold title. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. Lendmire’s piece on HELOCs for portfolio investors holding rentals in an LLC covers that structure in depth, and the loan side of any LLC file is subject to lender program eligibility.
Occupancy changes the answer. A duplex where you live in one unit is typically reviewed as a primary residence. Rent both units and it’s reviewed as an investment property, with the 70% ceiling and 700 floor. A unit that’s vacant between tenants is a case-by-case call. Ask first.
A line on the rental you already own. Some investors keep a low first mortgage on a rental and add a line behind it. Lendmire’s article Investment Property HELOC Lenders for Investors Keeping a Low First Lien explains how that plays out. The tradeoff is the tighter investment-collateral limits shown above.
Draw rules can surprise you. At least 75% of the line is drawn at closing. You start paying interest on most of it right away, so don’t open a line far larger than the gap you’re filling. Lines run $25,000 to $750,000, and the minimum varies by state.
Exposure limits. A borrower is limited to three lines. Combined exposure caps between $750,000 and $2,000,000 depending on the structure. A borrower with more than 15 financed properties isn’t eligible.
Credit history matters. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, foreclosure history follows seven years, and a deed-in-lieu, pre-foreclosure, or short sale follows four.
Availability is narrower. HELOCs through Lendmire’s network are available only in its 16 full-service states. That’s a smaller map than the DSCR footprint of 41 markets, including Washington, D.C. A DSCR purchase can be arranged in a market where the line can’t.
The line can freeze. HELOC agreements generally let the lender freeze or reduce a line if the home’s value falls or your finances weaken. The line has to be funded before you go under contract, and a frozen line mid-deal would leave you short. Draw the cash early and confirm it’s in your account.
The Stack: Risk, Exit Plan, and Stress Test
A fully HELOC-funded down payment means close to 100% of the purchase is borrowed. It’s spread across two liens on two properties. That’s leverage stacked on leverage. It can work, but it needs a plan.
Floating cost. HELOC pricing floats across both the draw and the repayment period and never converts to fixed. Per the CFPB, a line gives you a draw period followed by a repayment period. The booklet adds that variable rates are tied to a public index, so payments can move even when you draw nothing new. A DSCR loan, by contrast, usually carries a fixed rate for the term. Your blended cost can drift up while the rental’s rent stays flat.
The repayment cliff. Investment lines run a five-year interest-only draw, then 25 years of fully amortizing repayment. Any balance left at the end of the draw means principal payments on top of interest. Primary-home lines also offer a three-year draw with 17 years of repayment. Know which one you’re signing.
The allocation question. If the HELOC cash went into the rental, the payment belongs in that rental’s real numbers. If it was spent elsewhere, it doesn’t. Be honest about which one you did.
Run a stress test before you commit. Take the rent down, the vacancy up, and the floating payment higher, then see whether you still carry both loans from the rental and your own income. If the answer depends on everything going right, the plan is too thin. Also decide how you’ll pay the line down: excess rent, a later refinance, or a sale. A plan with no exit is a bet.
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.
HELOC, Cash-Out, or Cash: Choosing the Tool
The HELOC is one way to reach equity. It’s not always the right one. The decision turns on what you own, what you need, and how much payment risk you’ll carry.
| Option | Best When | Watch For |
|---|---|---|
| HELOC on primary home | Equity is in your residence | Residence is the collateral |
| DSCR cash-out refinance | Equity is in a seasoned rental | About 75% LTV cap; ~6 months seasoning |
| Savings | You have unborrowed cash | Draining your reserves |
A DSCR cash-out refinance on an existing rental pulls equity out against that property. It tops out around 75% LTV across most of the network on a standard rental, and about six months of seasoning is the common expectation. On short-term-rental collateral, the cash-out ceiling is 70%. The money comes as a lump sum with a fixed structure, so you don’t carry a floating balance. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Pick the HELOC when your equity sits in a residence and you want flexibility on how much you draw. Pick cash-out when the equity sits in a rental that has already been held long enough to season. Pick neither when the rental barely covers its own payment. In that case the extra debt just stretches a thin deal.
Local investors have one real edge. You know your rents and your submarkets, so you can sanity-check an automated valuation against what’s actually happening on the street. If the estimate looks off, you can request a full appraisal. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Frequently Asked Questions
Can I use a HELOC to pay for the whole purchase?
Rarely, and it’s not a good idea. DSCR purchase loans typically finance 75%-80% of the price, with select programs reaching 85%. The HELOC would fill the gap, but the lender tests down payment, closing costs, and reserves separately. Borrowing everything leaves you with no seasoned cash behind the property.
Can I open a HELOC on the property I’m buying?
No. You don’t own it yet, and the equity has to exist before the line can be written. The line must be funded before you go under contract, using equity in a home or rental you already hold.
Does the HELOC payment count against my DSCR?
Usually not. The coverage ratio compares the rental’s rent to its PITIA, and the HELOC payment typically sits outside it. But it’s still a monthly obligation you have to pay. Some lenders weigh it in the overall debt picture, so confirm how yours treats it.
Can my LLC take out the line?
No. Titles on these lines are limited to you personally or an inter vivos revocable living trust. If the property sits in an LLC, you’d need a vesting change or a DSCR cash-out refinance instead, subject to program terms.
What happens if the line is frozen or reduced?
The lender can generally freeze or cut the limit if the home’s value drops or your finances weaken. If that happens before you’ve drawn the cash, the plan stalls. Fund the line and move the cash to your account before you sign the purchase contract.
