The Quick Read: The best program is the one that matches your property, your equity, and the lender that will fund the purchase. A home equity line of credit supplies cash for the down payment, and a separate loan buys the house. Across Lendmire’s wholesale network, a line secured by an investment property tops out at 70% combined loan-to-value (CLTV) with a 700 credit score. A line secured by your primary residence can reach higher, which is why most investors who use this strategy borrow against their own home. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
- An investment-property line runs 70% CLTV at 700 or better, up to $500,000.
- A primary-residence or second-home line reaches 90% CLTV only at a 720-or-better credit profile.
- An LLC cannot hold title on these lines. Individuals and revocable living trusts can.
- The HELOC payment sits outside the DSCR ratio but inside your real cash flow.
- Whether the purchase lender accepts borrowed funds is a separate test, and it varies by program.
What a HELOC Actually Does When You Buy a Rental
A HELOC does not buy the house. It is a revolving line of credit secured by property you already own, and you borrow from it as needed. The cash lands in your account, and you use it as a down payment on a different property. A second loan, usually a DSCR purchase loan, finances the rest.
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.
A DSCR loan (debt service coverage ratio loan) is an investor loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC is underwritten on you and the collateral property. The DSCR loan is underwritten on the new rental. They are two files with two sets of rules.
BiggerPockets describes the strategy the same way: a second lien on a property you own, with the cash used as a down payment elsewhere. The same post names the cost. The equity in the original property is now tied up as collateral.
The upside is speed of action. You can make offers with cash already available, and you do not have to sell anything first. The downside is that the debt stays with you, whether or not the new rental performs.
How Underwriting Treats It, Step by Step
Here is the sequence a borrower follows, and what each lender checks along the way.
1. Pick the collateral. The line is secured by your primary residence, a second home, or an existing rental. This choice sets your leverage ceiling, so it comes first.
2. Qualify the line. The HELOC lender looks at credit, debts, and the equity left after the combined loan limit. SmartAsset notes that lenders check income and existing debts, and that the amount of equity caps the line size. On the network’s programs, debt-to-income (DTI) runs to a 50% maximum, qualified on the interest-only payment calculated on the maximum draw.
3. Value the property. Lines at or below $500,000 ordinarily run an automated valuation instead of a traditional appraisal. A higher CLTV may require a second valuation. You can request a full appraisal in any case.
4. Close and draw. On the network’s programs, at least 75% of the line is drawn at closing. You therefore carry most of the balance from the start, so size the line to the money you need.
5. Document the money. The purchase lender will want a paper trail from the draw to your down payment. Keep the draw in its own account and do not mix it with personal spending.
6. Qualify the purchase loan separately. This file is reviewed on the rental’s income, your credit, and your reserves.
7. Plan the end of the draw period. When the interest-only draw ends, a fully amortizing repayment begins and the payment steps up.
Step 6 is where files stall. Borrowed funds can be treated differently for the down payment, for closing costs, and for reserves. Treat these as three separate tests and ask about each before you open the line.
Which Is the Best HELOC Program to Buy an Investment House?
The best program for your situation depends on three things. They are which property secures the line, how the lender underwrites it, and whether the purchase lender will accept borrowed money. No single product wins on all three for every borrower.
| Factor | Primary-residence line | Rental-secured line |
|---|---|---|
| Max CLTV | Up to 90% at 720+ | 70% at 700+ |
| Max line size | Up to $750,000 | Up to $500,000 |
| Credit floor | 600 program floor | 700, no tier below |
| Valuation | Automated at or under $500,000 | Automated in practice |
| Draw structure | 3-year or 5-year draw options | 5-year draw, 25-year repayment |
Two details change real decisions.
First, an investment-property line has only two credit tiers, and both reach the same 70% CLTV. A 720 score buys you eligibility, not extra leverage. A 700 is a hard floor with nothing beneath it.
Second, a primary-residence line carries more room, and it also puts your home on the line. SmartAsset warns that a borrower who misses HELOC payments risks losing the primary residence to foreclosure. If the rental sits vacant, the line stays owed.
The lenders that write these lines vary in appetite, and a broker that shops several wholesale lenders can match your scenario to the right program. Lendmire is a mortgage broker, not a lender. It arranges financing through select wholesale partners, and every figure here is subject to lender guidelines and full file review.
The Network’s Program Parameters in Plain English
These ranges come from the wholesale programs Lendmire places files with. They are typical guidance, not promises, and each figure applies only within its own program’s terms.
Leverage. An investment property line caps at 70% CLTV. A primary-residence or second-home line reaches 90% CLTV, but only at a 720-or-better credit profile. Market surveys may show higher or lower caps from lenders, and those describe the wider market, not this network.
Line size. Lines run from $25,000 to $750,000. Anything above $500,000 is primary-residence only and requires a full appraisal.
Structure. The line can sit in first or second lien position. Pricing floats during both the draw and repayment periods and never converts to fixed. A primary residence offers a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Investment lines use the 5-year draw and 25-year repayment only.
Credit and debt. The program floor is 600, with the score keyed to the primary wage earner. A ratio above 45% DTI requires a 680 minimum. Investment lines floor at 700, so that rule never binds you on a rental-secured line.
Property types. Eligible properties include single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
Exposure. A borrower is limited to three lines, and anyone with more than 15 financed properties is not eligible.
Availability. These lines are available in 16 full-service states. That is narrower than Lendmire’s 41-market DSCR footprint, so confirm your state first.
Two points deserve emphasis. Bankruptcy requires four years from discharge or dismissal. And a property listed for sale, or listed within the past 60 days, is ineligible in several states, so check before you open a line on a home you may sell.
Structures and Variations Beyond a Standard Line
A HELOC is one tool. The CFPB explains that HELOCs usually carry variable rates, so payments can change month to month. Some plans let you convert part of the balance to a fixed rate. The network’s lines do not convert, so pricing keeps floating through the whole term.
The CFPB booklet on HELOCs adds that when the draw period ends, payments can rise significantly. Run that stress test before you commit, not after.
Other routes can fund the same down payment:
| Option | Choose it if |
|---|---|
| HELOC on your home | You want flexible draws and have strong equity |
| Closed-end second lien | You want one lump sum and no revolving access |
| DSCR cash-out on a rental | You own a rental with equity and want a lump sum |
| Standard cash-out refinance | You would replace a first mortgage anyway |
A DSCR cash-out refinance pulls equity from an existing rental. It tops out around 75% LTV across most of the network, with about 6 months of seasoning (ownership time) as the common expectation. The 75% ceiling applies to standard rentals. Lendmire’s pull-equity guide on cash-out refinancing an investment property walks through that structure. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
If you own a low-rate first mortgage, a second lien lets you keep it in place. A cash-out refinance would replace it. That tradeoff can decide which route wins.
Where the General Rule Breaks
Property deeded to an LLC. A HELOC cannot go on a property titled to an LLC, corporation, or partnership. Only individuals and inter vivos revocable living trusts can hold title, subject to program terms. This is the sharpest structural difference from a DSCR loan. If your rental already sits in an LLC, you need a vesting change or a DSCR cash-out instead.
No equity anywhere. A first-time investor with no rental and no home equity has nothing to borrow against. The better path is a DSCR purchase with your own cash down.
Fully borrowed down payment. Some purchase programs accept borrowed funds for the down payment. Others cap the borrowed share or want part of the down payment in your own seasoned cash. A plan built on 100% HELOC money can fail on that rule alone.
Reserves. Borrowed funds are commonly excluded from reserves, even where they are accepted for the down payment. Reserves on the DSCR side commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and HOA dues). They vary by lender, leverage, loan size, and transaction type. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.
Recent rehab. Automated valuations may not capture the value you just created. A fresh renovation can leave you with a lower line than you expected.
Credit-score confusion. One lender’s 720 and another’s 700 can both be correct for their own programs. A line above $500,000 is primary-residence only and calls for 700 or better (720 on the longer-runway structure of the 5-year draw program).
Owning many properties. Past 15 financed properties, a borrower is not eligible for these lines. Plan your sequence before you reach that count.
The Purchase Side: How the DSCR Loan Sees Your Down Payment
Once the HELOC cash is in your account, a different lender asks questions. The DSCR ratio compares monthly rent to the new property’s PITIA. Your HELOC payment is not part of that ratio. It is a second obligation the rent was never asked to cover.
A common mistake follows from that. Clearing the ratio does not mean the property produces positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
Purchase leverage on most DSCR files lands at 75% to 80% LTV, or 20% to 25% down. Select programs reach 85% LTV with roughly a 700-plus score. A bigger down payment lowers the monthly payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Most programs want around 660 credit, and a 620 floor exists in parts of the network. A 700-plus score unlocks the strongest leverage tiers. Coverage of 1.00 is where many select programs start. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted.
Lendmire’s complete DSCR loans guide covers the full qualification picture for the purchase side.
What the Decision Looks Like in Practice
Picture three investors with three different answers.
The homeowner with strong equity. Say you own a primary residence, carry a 720-plus credit profile, and have plenty of CLTV room. A primary-residence line can fund the down payment on a rental, and a DSCR purchase at 75% LTV finances the rest. If the rent clears around 1.2x coverage, the new loan looks healthy on its own. The exposure is your home, so keep a cushion for vacancy. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The investor holding rentals in an LLC. Your equity sits in properties a HELOC cannot touch. The cleaner route is a DSCR cash-out on one rental, at up to 75% LTV after about 6 months of seasoning. That pulls a lump sum without moving title. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The first-time buyer with no equity. There is nothing to borrow against. Save the down payment, then use a DSCR purchase at 75% to 80% LTV. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
In all three, stack the debts honestly. You carry the first mortgage, the line, and the new DSCR loan. A rent shortfall or a vacancy hits all three at once.

Comparing HELOC Options for Your Property
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. The brokerage places files with select wholesale lenders, and the right fit depends on your scenario.
Frequently Asked Questions
Can I use a HELOC on my primary residence to buy a rental?
Often yes, subject to lender guidelines. The line is secured by your home, and the cash can go toward a down payment on the rental. The purchase lender then reviews whether it accepts borrowed funds for the down payment, closing costs, and reserves. Ask about all three before you draw.
How much can I borrow against an existing rental?
On this network, an investment-property line caps at 70% CLTV, up to $500,000, with a 700 minimum credit score. Both 700 and 720 reach the same 70%, so a higher score does not buy more leverage. A full appraisal is not required, since valuation is automated at that size.
Can I put a HELOC on a property owned by my LLC?
Not on these lines. Title must be held by an individual or a revocable living trust. If your property is already in an LLC, you would need to change the vesting or use a DSCR cash-out refinance instead.
Does my HELOC payment count against the DSCR ratio?
No. The ratio compares rent to the new property’s payment alone. The line payment still reduces your real cash flow, and it counts toward DTI when the line is underwritten. Keep both in view when you size the deal.
Are HELOC lenders consistent about investment properties?
No. Appetite for rental-secured lines varies from lender to lender. A broker that works with several wholesale lenders can match your scenario to a program that actually writes it.
