The Quick Read: A home equity line of credit (HELOC) usually supplies the cash for the down payment, closing costs, or repairs on your next rental. A separate loan, often a DSCR loan, buys the property itself. The two loans are judged on different things, and the order you do them in matters.
- A HELOC is judged on you and the equity in a property you already own. The purchase loan is judged mainly on the new property’s rent.
- On an investment property, lines through our network cap at 70% CLTV and $500,000, with a 700 minimum credit score.
- A line on your primary home can reach 90% CLTV, but only at a 720-or-better credit profile.
- Open the line before you go under contract, and ask the purchase lender whether borrowed down-payment funds are accepted.
- A HELOC payment generally sits outside the DSCR calculation, but it still comes out of the same rent.
Key Terms Defined
HELOC (home equity line of credit): a revolving credit line secured by a property you own. You draw cash as needed, up to a limit.
CLTV (combined loan-to-value): all loans secured by the property, added together, divided by its value. Your existing mortgage and the new line both count.
Draw period: the stretch when you can borrow from the line. Payments are often interest-only during this phase.
Repayment period: the stretch after the draw ends, when you can no longer borrow and the balance is paid down over time.
DSCR (debt service coverage ratio): monthly rent divided by the property’s monthly payment, which covers principal, interest, taxes, insurance, and any HOA dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Reserves: liquid cash a lender wants you to keep after closing, usually counted in months of payments.
Seasoning: the waiting period a lender requires between two events, such as buying a property and refinancing 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.
Two Loans, Two Different Questions
The HELOC and the purchase loan never meet in the middle. Each lender asks its own question, and you have to pass both.
The HELOC lender asks about the property you already own. How much is it worth? What do you owe on it? What does your credit look like? How much of your income already goes to debt? Our network caps DTI (debt-to-income ratio, the share of income that goes to debt payments) at 50% on these lines. Lenders review your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
The purchase lender asks about the rental you are buying. On a DSCR loan, that means the rent against the payment. The first lender cares about your equity, and the second cares about the new property’s income.
One point trips up first-timers. You cannot open a HELOC on the rental you have not bought yet. The line has to sit on something you already own. That is either your primary home or a property in your portfolio.
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. That difference is why investors with heavy personal debt often use DSCR for the purchase side. Lendmire’s complete DSCR loans guide covers that side of the file in full.
How the Money Moves, Step by Step
Here is the sequence that works, in order.
1. Open the line first. It has to exist and be documented before you make an offer. Opening it after you are under contract adds pressure for no reason.
2. Size the line backward from the target purchase. Add the down payment percentage times the price, the closing costs, any rehab, and your reserves. That total is the cash you need.
3. Draw into your own account. The purchase lender has to source the funds. A clean trail of dated draws makes that easy.
4. Confirm how the purchase lender treats borrowed funds. Some programs accept them as down payment. Some cap them. Some require a slice of your own unborrowed money. Ask before you draw.
5. Close the purchase loan. The new property is now collateral for its own loan, and the line stays on the original property.
6. Carry two payments. The DSCR file may not count the HELOC payment, but you still pay both from your cash flow.
7. Plan the exit. Pay the line down from cash flow or sale proceeds, or refinance the new rental and use the proceeds to retire the line.
One feature of our network surprises people. On an investment line, at least 75% of the line is drawn at closing. That means you cannot open a large line and leave most of it idle as a safety net. Size the line closer to the need.
Home Line or Rental Line?
You can place the line on your own home or on a rental you already hold. A line on your home is generally easier to get. Benzinga notes that a HELOC on an investment property can fund renovations or help buy more rentals. Lenders treat rental collateral as higher risk, so the box is tighter.
| Factor | Line on primary home | Line on a rental |
|---|---|---|
| Max CLTV | Up to 90% (720+ only) | 70% |
| Min credit score | Program floor of 600 | 700 |
| Max line size | Up to $750,000 | $500,000 total |
| Draw structure | 3- or 5-year interest-only | 5-year draw, 25-year repayment |
| Valuation | Automated, or full above $500,000 | Usually automated |
A few notes on the table. The 90% ceiling exists only with a 720-or-better credit profile, and many borrowers will see a lower cap. The investment line has no tier above 70%, and credit above 700 buys eligibility rather than extra leverage. There is also no investment tier above $500,000. Any line above $500,000 is primary-residence only, needs a full appraisal, and caps at 75% CLTV.
Because investment lines top out at $500,000, they commonly close with an automated valuation and no traditional appraisal. A borrower can still ask for a full appraisal.

How Much Can the Line Provide?
The equity math is simple. Take the property’s value, multiply it by the lender’s CLTV cap, and subtract what you already owe. The CFPB’s HELOC booklet walks through this formula with an illustration: 75% of a $100,000 value, less a $40,000 mortgage. Treat that as a teaching example, not a market standard.
Now run it in percentages with network numbers. Say you own a rental with a first mortgage equal to 50% of its value. On an investment property, the 70% CLTV ceiling leaves headroom equal to 20% of the value. Your own primary home is different. If the first mortgage is 60% of value and you have a 720-or-better profile, the 90% ceiling leaves 30% of value. Either way, the line size also has to respect the $500,000 investment cap or the primary-home limits.
Now work backward from the purchase. Most purchase files across our network land at 75% to 80% LTV on a purchase, so you need 20% to 25% down. Select programs reach 85% LTV on a purchase, which means 15% down, typically with a score around 700 or better. Add closing costs, any rehab, and reserves, which commonly run around six months of payments on a DSCR file. That total is your target line.
Checking these numbers against both lenders’ rules before you draw saves most of the grief. A larger down payment lowers the new loan’s payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files have enough equity and enough rental coverage.
What the Purchase Lender Sees
On the purchase side, the lender sees a new rental, a down payment, and a source for that down payment. A line against another property is borrowed money. Programs differ on how they treat it, so the answer comes from the specific program, not from a general rule.
Coverage is the second thing the lender checks. Many select DSCR programs start at 1.00, meaning the rent just covers the payment. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage. Credit matters too. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
Here is the piece many first-time investors miss. DSCR compares rent to the property’s payment, and nothing else. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the ratio, and so does your HELOC payment.
Picture a rental that clears around 1.25x. The DSCR file looks healthy. But the line payment, the rental’s own operating costs, and one vacant month can still leave you cash-negative at the household level. The new property needs to carry its own loan and the line.
The structure itself is usually simple. The spine of the DSCR side is the 30-year fixed. Extended terms, such as 40-year, and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
Stress-Test Before You Draw
A HELOC is not a fixed-payment loan. The CFPB explains that a HELOC has a draw period followed by a repayment period. Payments are often significantly higher once repayment starts, and repayment is often scheduled over ten or 20 years. On our network, pricing floats through both the draw and the repayment period and never converts to a fixed amount.
The CFPB’s consumer brochure on HELOC risks adds that with a variable structure, the payment can change even when you draw no more money. It also warns that the end of the draw period can leave a balloon payment due all at once.
On an investment line, that means five years of interest-only payments and then a 25-year amortizing schedule. The payment on day one of repayment is not the payment you were living with in year four. Plan for that shift now.
Run three tests before you draw:
- Payment shift. What does your cash flow look like when interest-only becomes fully amortizing?
- Vacancy. Can you carry both loans through a month or two with no rent?
- Pricing movement. If the line’s cost floats upward, does the rental still cover both obligations?
If the answer to any of these is no, shrink the draw or skip the strategy.
Banks.com describes a HELOC plainly as a second mortgage, which means more debt and higher monthly costs. That framing is blunt, and it is also correct.
Another risk is easy to skip: your collateral is a property you already own. If you place the line on your own home, a default puts that home at risk. If you place it on a rental, trouble on one property can spread to the other. Total debt across two properties and two liens is the number to watch.
Where the General Rule Breaks
The steps above hold for a typical borrower with a typical property. These edge cases are where files go sideways.
LLC title. HELOCs through our network require title in the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. DSCR loans can often close in an LLC, subject to program terms. If your rental already sits in an LLC, you need a vesting change or a DSCR cash-out refinance instead.
Property types. The line side does not offer manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agriculturally zoned properties. The DSCR side does not offer manufactured homes (single- and double-wide), log homes, or barndominiums. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible on the line side. Check both lists before you commit to a target.
Borrower limits. A borrower is limited to three lines in total. A borrower who owns more than 15 financed properties is not eligible. Investors scaling a portfolio may hit these walls before they hit equity limits.
Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, foreclosure-family history follows a seven-year path for a foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale. Housing history standards also apply across all financed properties.
Prepayment penalties. Some DSCR loans carry them. If your exit plan is a cash-out refinance of the new rental, check the penalty terms before you close the purchase. Otherwise a more affordable exit may cost more than you expected.
Availability. Lendmire arranges home equity lines through select wholesale partners in 16 full-service states. That is narrower than its DSCR footprint of 41 markets, including Washington, D.C.
HELOC, Cash-Out Refinance, or Something Else?
A HELOC is not the only way to move equity into a deal. The right tool depends on how long you will hold the debt, how much you need, and how the property is titled.
| Factor | HELOC | Cash-out refinance |
|---|---|---|
| Structure | Revolving line, floats | One new loan, term options |
| Investment max | 70% CLTV, $500,000 | 75% LTV on standard rentals |
| Best for | Short-term bridge | Larger, longer-term needs |
| Title | Individual or revocable trust | LLC possible, per program |
The cash-out line deserves a closer look. On a standard rental, a cash-out refinance across most of the network tops out around 75% LTV. A short-term-rental cash-out sits around 70%. Expect about six months of seasoning as the common expectation. On the DSCR side, the cash-out loan is underwritten to the rental’s income, which keeps your personal DTI out of the center of the file. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Lendmire’s article How to Time a Rental Cash-Out Refinance Before the Next Purchase covers the sequencing in detail.
A HELOC tends to fit best when you need a modest amount for a limited stretch and you plan to repay it from cash flow or a refinance. A cash-out refinance fits when you need more money, want a defined payoff schedule, or hold the rental in an LLC.
Short-term rentals add another layer. Purchase leverage goes to 75% LTV, refinance sits around 70%, and a cash-out sits at 70%. Expect a 640-plus score and about 12 months of hosting history. Coverage floors are set separately for purchases and refinances. 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. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
What the Decision Looks Like in Practice
Consider an investor with a primary home carrying a modest first mortgage and a strong credit profile. She is eyeing a duplex that she thinks will clear roughly 1.2x on the DSCR side. She plans to buy at 75% LTV on a purchase, so she needs 25% down plus closing costs and reserves. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Her options split three ways. She could draw on her home’s line, if the purchase lender accepts borrowed down payment funds. She could use cash, if she has it. Or she could refinance an existing rental into a larger loan. The HELOC makes sense only if all three tests pass. The purchase lender accepts the source. The rental carries both payments with room to spare. She has a repayment plan for the line before she opens it.
Now consider a second investor who holds everything in LLCs. He has equity, but no individual-name property to place a line on. The HELOC route does not fit his structure. A DSCR cash-out refinance on an LLC-held rental is the practical path, subject to program terms.
A third investor wants to scale across several deals. He treats the line as a bridge. He draws for the down payment, buys, stabilizes, and refinances the new rental to pay the line back to a low balance. Then he repeats. This works when each step clears the next lender’s rules, and when prepayment terms do not punish the refinance.
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.
Across the wholesale network, the pattern in files like these is consistent. The deals that stall rarely stall on the HELOC itself. They stall when the purchase lender will not count the borrowed funds, when reserves fall short after the draw, or when the title sits in the wrong name. Each of these takes one phone call to check before you commit.

Frequently Asked Questions
Can a HELOC buy a rental property outright?
Rarely. A HELOC typically covers the down payment, closing costs, or rehab, while a separate loan closes the purchase. On an investment property, our network caps lines at $500,000, so the line alone rarely covers a full price. Most investors pair the line with a DSCR purchase loan.
Can I open a HELOC on a rental held in an LLC?
Not directly. Lines through our network require title in an individual or an inter vivos revocable living trust. A property already deeded to an LLC needs a vesting change or a DSCR cash-out refinance.
Does the HELOC payment count against my DSCR?
Generally no. The DSCR calculation compares rent to the new property’s payment, which covers principal, interest, taxes, insurance, and any HOA dues. The HELOC payment still comes out of your cash flow, so the new rental needs to carry both. Clearing 1.00 also does not mean positive cash flow.
What credit score do I need for a line on a rental?
A 700 minimum applies on investment lines through our network, and 720 and 700 both reach the same 70% CLTV ceiling. Primary-home lines floor lower, with a 600 program floor. The 90% CLTV ceiling on a primary home exists only at a 720-or-better profile.
Does it matter when I open the line?
Yes. Open it before you go under contract, because the line has to exist and be documented before the offer. Also remember that at least 75% of the line is drawn at closing, so size it to the need. Confirm the purchase lender’s treatment of borrowed funds before you draw.
