The Quick Read: Yes, you can use a home equity line of credit (HELOC) to fund the down payment on a rental. Most investors pair it with a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC is borrowed money, so the purchase lender treats it as debt, not savings. Plan for both a leverage limit on the line and a reserve requirement on the new loan.
The Short Version
- A HELOC is a down-payment tool, not a purchase loan. You borrow against a property you own, then put that cash into a separate rental purchase.
- Across the wholesale network Lendmire places files with, a line on an investment property tops out at 70% CLTV, $500,000, and a 700 credit score.
- A line on your primary residence can reach 90% CLTV, but only at a 720-or-better credit profile.
- The DSCR lender still wants your funds documented, and it still wants cash left over after closing.
- You end up with two loans on two properties. That is the real decision.
- Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Key Terms Defined
HELOC: A revolving line of credit secured by a property you own. You draw cash as needed, up to the limit.
How large a line the equity supports in your market.
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 tiers reach 640; primary-residence tiers reach 600.
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: investment property runs to 70% combined LTV with a 700 credit floor and a $500,000 cap; a second home runs to 90% at a 640 floor with a $500,000 cap; a primary residence reaches up to 90% at a 600 floor, and its $750,000 maximum line applies only at 75% combined LTV or below with 720+ credit 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.
CLTV (combined loan-to-value): All loans against a property, added together, divided by its value.
Lien position: Your place in line for repayment if the property is sold. A HELOC can sit in first or second position.
Draw period: The stretch when you can pull money from the line, usually paying interest only.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly payment. Ratios above 1.00 mean rent exceeds the payment.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the full monthly obligation the DSCR ratio uses.
Reserves: Liquid cash left after closing, measured in months of PITIA.
Seasoning: The waiting period a lender wants before a refinance or cash-out.
How Does a HELOC Actually Fund a Rental Purchase?
You draw on the line, park the cash in your bank account, and use it as the down payment on a separate rental. Then a DSCR loan covers the rest of the price, and the property’s rent is what that loan is underwritten against.
Here is the sequence, start to finish:
1. Equity screen. The HELOC lender values the property securing the line and checks combined debt against it.
2. Draw. You pull cash from the line and move it to your account.
3. Documentation. The DSCR lender asks where the down payment came from and sees the HELOC draw on your credit report and balance sheet.
4. Appraisal. The rental gets valued. Appraisers borrow the agency form names here: Form 1007 for a single-family rent schedule and Form 1025 for two-to-four-unit income reporting. The underwriting decision itself is not an agency decision.
5. Review. The lender checks credit, rent coverage, title, and reserves.
Most DSCR purchases land at 75% to 80% LTV, meaning 20% to 25% down. Select higher-leverage programs reach 85% LTV with about a 700+ score. Your HELOC draw has to cover that percentage plus closing costs, and you still need cash left over. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
How Do Underwriters Treat HELOC Money?
They treat it as a liability. The draw does not count as seasoned personal savings, and a lender will want the paper trail to show exactly where the cash came from.
Keep it clean. Draw into a bank account you control, avoid mixing the money with unrelated deposits, and keep the statements. A commingled account turns a simple file into a long conversation.
Here is the part investors often miss. The DSCR calculation looks at the subject rental only: rent against its own PITIA. Your HELOC payment on the source property generally does not enter that math. It still counts in the bigger picture, though. It appears on your credit, it drains your monthly cash, and it competes with reserves for the same dollars.
Reserves are where files stumble. They vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common, conservative rate-term files at modest leverage under $1,500,000 can see them waived, and larger loans typically step up to about 9 months. A HELOC that funds the entire down payment can leave you thin on exactly this test.
One more thing. Clearing 1.00 coverage is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. If you are also making HELOC payments, those sit outside it too.
Primary Residence or Rental: Which Equity Do You Tap?
Your primary residence supports more leverage than a rental does, and the gap is wide. One credit union’s guide reports that investment properties and second homes often cap near 70% to 75% while primary residences reach 85% to 90%. Those are market-wide figures. Here are the network figures, which are what matter for files placed through Lendmire.
| Factor | Primary residence line | Investment property line |
|---|---|---|
| Max CLTV | 90% (720+ only) | 70% |
| Min credit | 600 program floor | 700, hard floor |
| Line size | $25,000 to $750,000 | Up to $500,000 |
| Draw structure | 3-yr or 5-yr interest-only draw | 5-yr draw, 25-yr repayment |
Notice what is missing on the investment side: a higher tier. A 700 score and a 720 score both land at 70%. Credit above 700 buys eligibility, not extra leverage.
Two structural details apply on both lines. At least 75% of the line is drawn at closing, so you start paying on most of it immediately. And the cost of the line floats for its whole life. It never converts to fixed. Opening a huge line “just in case” is not free.
Because investment lines cap at $500,000, they sit in the automated-valuation lane and commonly close without a traditional appraisal. Lines above $500,000 are primary-residence only, cap at 75% CLTV, and need a full appraisal.
Where the General Rule Breaks
The rule is simple: borrow against equity, fund the down payment, buy the rental. Here are the cases where it stops working.
The rental is held in an LLC. HELOC programs in the network require title held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title. A property already deeded into an LLC needs a vesting change first, or a DSCR cash-out refinance instead. (DSCR purchases can often close in an LLC, subject to lender program eligibility.) That is a real structural difference between the two products.
The property type is off the list. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network. The HELOC side also excludes manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning. Single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos, are eligible.
The seasoning clock. Say you buy with a HELOC-funded down payment and plan to pull equity back out later. Cash-out refinances on most files want about 6 months of seasoning, usually measured from the deed recording date, not the date you drew on the line. Some lenders treat an all-cash purchase more generously, but a purchase funded partly by borrowed money generally does not fit that treatment.
The rate-and-term trap. If you refinance to pay off the first loan and walk away with even a little extra cash, the file is typically reclassified as a cash-out refinance. The longer seasoning and lower leverage cap then apply. Model the HELOC payoff carefully before you assume a clean rate-and-term.
Owner-occupancy and location overlays. In Texas, a 12-day waiting period, a one-lien-at-a-time rule, and 12-month seasoning bind primary residences only. Texas second homes and investment properties are eligible as non-homestead transactions, and properties are limited to 10 acres. In Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington, a property listed for sale in the past 60 days is ineligible. New Mexico and Ohio cap CLTV based on the credit profile. Tennessee also shortens the draw and repayment periods on primary-residence lines.
Too many lines or properties. 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 one. A borrower with more than 15 financed properties is not eligible.
Availability. Lendmire brokers HELOCs in its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than its DSCR investor loan footprint of 41 markets, including Washington, D.C.
What Does the DSCR Side Look Like?
Once the down payment is in hand, the DSCR loan has its own tests. Across the wholesale network, loan sizes run roughly up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures. Credit varies by program: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
Coverage matters too. Some select programs start at 1.00 coverage. That is a program floor, not the standard. Stronger ratios open better pricing and leverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence.
Term options help too. The spine is the 30-year fixed. Extended terms (40-year) and interest-only periods are available through select lenders, and ARM structures exist for investors who want them. Our complete DSCR loans guide walks through every tier in detail.
A bigger down payment lowers the monthly obligation and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
A Worked Picture
Run the numbers on this shape of deal. Say you own a primary residence with a mortgage, a 740 score, and enough equity that a line fits under the 90% CLTV ceiling. You draw on that line to fund the 25% down payment on a rental, taking the DSCR loan to 75% LTV. The rent clears roughly 1.2x coverage. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
On paper, that looks clean. Now look at the whole stack.
- The primary residence now carries a first mortgage and a line that floats.
- The rental carries its own mortgage.
- Your cash reserves must still satisfy the DSCR lender after closing.
- If a tenant leaves, you cover two payment streams until the unit is leased again.
One investor forum thread put it bluntly: borrowing against your own home is, in a roundabout way, spreading the love and thinning your equity. That is fair. A HELOC converts idle equity into a down payment, but it also adds a lien to a house that produces no rent.
HELOC or DSCR Cash-Out: A Toss-Up?
Not quite. It depends on where your equity sits and what you want next.
Use a HELOC when the equity is in your own home, the cash need is modest, and you can pay the line down. Many investors treat it as a short-term bridge: draw, buy, then refinance the rental and pay the line toward zero.
Use a DSCR cash-out when the equity sits in a rental you already own. Cash-out tops out around 75% LTV across most of the network, with about 6 months of seasoning expected, and it qualifies primarily on property-level rental income covering the payment. It also scales better. Each rental is underwritten on its own income, while a HELOC is limited to one pool of equity. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Honestly, the stronger play for a portfolio builder is usually to start with whichever route leaves the most breathing room in reserves. For a first deal, though, a HELOC against a primary home can make sense.
What Lenders Check on the HELOC
Skip the guesswork. These are the main points on an equity line:
- DTI: 50% maximum. It drops to 45% for credit profiles from 600 to 679, and anything above 45% requires a 680 minimum. Lenders qualify you on the interest-only payment calculated on the maximum draw.
- Credit: A 600 program floor, with a single-bureau score model keyed to the primary wage earner. The report must be no more than 90 days old at closing, and there are no rescores.
- Derogatory history: Bankruptcy seasons in 4 years from discharge or dismissal. Investment files follow a 7-year path for foreclosure and 4 years for deed-in-lieu, pre-foreclosure, or short sale.
- Valuation: Lines at or below $500,000 ordinarily run an automated valuation, though a higher CLTV may require a secondary one.
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).
Common Mistakes
Assuming HELOC cash counts as savings. It does not. It shows as debt.
Forgetting reserves. The down payment is one test. Post-closing cash is a separate one.
Sizing the line to the maximum. With at least 75% drawn at closing, a bigger line means a bigger bill from day one.
Counting on 1.00 coverage as cash flow. Rent against PITIA is only one slice of the budget.
Ignoring the vesting. An LLC-held rental cannot carry a HELOC. Find that out before you apply.
Frequently Asked Questions
Can I use a HELOC on my primary home for the down payment on a rental?
Yes. That is the most common version of this strategy. A primary-residence line can reach 90% CLTV, but only at a 720-or-better credit profile. The DSCR lender will still document the funds, count the draw as debt, and require reserves after closing.
Can I take a HELOC on the rental I already own?
Yes, within limits. An investment-property line caps at 70% CLTV and $500,000, with a 700 credit minimum. It runs a 5-year draw and 25-year repayment structure, and the rental must be titled to you or your revocable trust, not an LLC.
Does the HELOC payment count against my DSCR?
Generally not. The DSCR ratio compares the subject rental’s rent to its own PITIA. The HELOC payment still affects your credit profile, your monthly cash, and your reserves, so a lender sees it even though the ratio does not.
What happens if the rental doesn’t cover its payment?
You would likely put more down, which means drawing more on the line. Qualification stays subject to lender guidelines, credit approval, and property review.
Is a HELOC better than a DSCR cash-out refinance?
It depends on where your equity is. A HELOC taps equity in a property you own, usually your home. A DSCR cash-out taps equity in a rental, tops out around 75% LTV, and scales with each property’s income. Many investors use both, in sequence.
