The Quick Read: A home equity line of credit (HELOC) puts cash in your account for the down payment, closing costs, and reserves on your next rental, while a separate DSCR loan buys the property and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The line does not buy anything. It funds the deal, and two different approvals have to line up.
- On an investment property, a HELOC across Lendmire’s wholesale network tops out at 70% CLTV and a $500,000 line, with a 700 minimum credit score.
- The line is judged on you and your equity. The DSCR loan is judged on the rent against the payment.
- The line has to be open and funded before you go to contract.
- Clearing the coverage test is not the same as positive cash flow, and the line’s payment sits outside that test.
Key Terms Defined
You will see these terms throughout. Each one is defined once here.
- HELOC: a revolving credit line secured by real estate, where you borrow against your equity as you need it.
- CLTV (combined loan-to-value): all loans secured by the property, added together, divided by its value.
- Lien: a lender’s legal claim on a property until the loan is paid off.
- Draw period: the stretch when you can borrow from the line, often with interest-only payments.
- Repayment period: the stretch after the draw ends, when the balance is paid down over time.
- DSCR (debt service coverage ratio): monthly rent divided by the property’s monthly payment, meaning principal, interest, taxes, insurance, and any HOA dues.
- PITIA: that full monthly payment: principal, interest, taxes, insurance, and association dues.
- Vesting: the legal name that holds title to the property, such as you personally or an LLC.
- Seasoning: the waiting period a lender wants before it treats a loan, balance, or ownership as established.
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.
How Does a HELOC Fit Into a Rental Purchase?
A HELOC sits in front of the purchase, not inside it. You borrow against equity you already own, park the cash in your own account, and then use it as the down payment on a DSCR loan. Two lenders, two files, two sets of rules.
The structure of the line itself is simple. The Consumer Financial Protection Bureau explains that a HELOC lets you borrow up to your limit during a draw period, with a 10-year draw as its example. Its HELOC brochure adds that some plans allow interest-only payments during the draw, so nothing goes toward principal. It also says a variable-rate payment can change even if you borrow nothing more. When the draw ends, repayment often runs over ten or 15 years, and some plans instead demand the whole balance at once.
Those are general consumer descriptions. The investment lines Lendmire places run a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and pricing floats through both phases. It never converts to fixed. That detail matters when you plan how long you will carry the balance.
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 is exactly why investors pair them with a line: the purchase loan cares about the rent, and the line cares about you.
For the full picture of how the purchase side works, the complete DSCR loans guide covers it start to finish.
Which Property Secures the Line?
Most investors borrow against their own home, because that is where the equity and the lender choices are. A line against an existing rental is possible, but fewer lenders offer it and the terms are tighter. You cannot open a line against a property you have not bought yet.
| Factor | Line on your home | Line on an existing rental |
|---|---|---|
| Collateral at risk | Your residence | The rental |
| Lender choice | Wider | Narrower |
| Network ceiling | Up to 90% CLTV, only at 720+ credit | 70% CLTV |
| Line size | Up to $750,000 | Up to $500,000 |
| Title | Individual or revocable trust | Individual or revocable trust |
Read the second column carefully. The 90% figure applies only to primary-residence and second-home lines, and only with a 720 or better credit profile. On an investment property, 70% CLTV is the ceiling at both the 700 and 720 tiers. Credit above 700 buys eligibility, not extra leverage. Market surveys of the broader HELOC industry quote higher figures, but those describe the wider market, not this network.
Lines above $500,000 are primary-residence only. They cap at 75% CLTV and require a full appraisal.
How Is the Line Sized and Underwritten?
The equity test comes first. Take the property’s value, multiply by the lender’s CLTV cap, subtract every lien already on it, and what remains is the room for your line. The CFPB’s HELOC booklet walks through the same arithmetic. You run it one property at a time.
Here is the percentage version. Say you borrow against a rental under the 70% CLTV investment cap. If the existing first mortgage sits at 50% of value, you have 20 points of room. If it sits at 60%, you have 10. Same property, same cap, very different line. Older, paid-down properties give you the most room, and recently financed ones give you the least.
Then the borrower side. Across the network, the line is underwritten on personal credit, debt-to-income, and the valuation:
- Credit: a 600 program floor exists, but investment lines require a 700 minimum. The score is a single-bureau model keyed to the primary wage earner, and the report can be no more than 90 days old at closing.
- Debt-to-income: 50% maximum. The line is qualified on the interest-only payment calculated on the maximum draw, not on what you plan to use.
- Valuation: an investment line caps at $500,000, so it is structurally in the automated-valuation lane. It commonly closes with no traditional appraisal, though a higher CLTV can trigger a secondary valuation, and you can request a full appraisal anyway.
- Draw at closing: at least 75% of the line is drawn at closing. Interest starts on that amount on day one.
That last point surprises people. A line you open just in case is not free. Size it to the cash you actually need.
What Does the DSCR Loan Do With That Money?
The DSCR loan treats the cash as your down payment and nothing more. It keeps its own leverage tier, credit floor, reserve rules, and property eligibility. A bigger down payment lowers the monthly payment and can lift the coverage number. It never erases a leverage cap.
Here are the program ranges to plan around, subject to lender guidelines:
- Purchases: most files land at 75%-80% LTV on a rental purchase, meaning 20%-25% down. Select programs reach 85% LTV on a purchase, with roughly a 700+ score.
- Cash-out refinances: about 75% LTV across most of the network on standard rentals, with around 6 months of seasoning as the common expectation.
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest tiers.
- Reserves: commonly around 6 months of PITIA. 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.
The real question is whether the lender accepts borrowed money as the down payment. Across the wholesale network, lenders fall into three camps. One accepts documented line proceeds. One caps the borrowed share and wants some seasoned cash of your own. One requires part or all of the down payment to be unborrowed. A plan that is 100% borrowed can fail on that point alone. Ask before you draw, not after.
Down payment and reserves are also separate tests. Borrowed money may count toward one and not the other, depending on the lender.
Keep the paper trail clean. Underwriters review recent bank statements and look at the source of large deposits. Save the HELOC agreement, the draw confirmation, and the statement showing the deposit.
The Buy-More-Rentals Loop, Step by Step
Investors who use this strategy repeatedly are running a cycle. Here is how it works in order:
1. Open the line early. It has to be open and funded before you go to contract.
2. Ask the purchase lender how it treats borrowed funds. Do this before the draw.
3. Draw and park the cash in your own account, with the paper trail intact.
4. Close the DSCR purchase on a property that clears both tests: enough equity behind the down payment, enough rent behind the payment.
5. Stabilize the rental. Get it leased, seasoned, and running.
6. Exit the line. Pay it down from cash flow, or refinance the new rental and use the proceeds to retire or reset the line.
7. Repeat once the line has room again.
The refinance step is where many investors rotate equity. The DSCR HELOC piece covers investors who already hold a DSCR first lien and want more equity access.
Where the Rules Break
The general rule is that equity plus rent buys the next rental. These edge cases are where it stops working.
LLC-owned rentals. Only individuals and revocable living trusts can hold title on these lines. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. This is the sharpest structural difference from a DSCR loan, and it is subject to program terms.
Property types. Eligible collateral includes 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-zoned properties are not offered. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered either.
Exposure caps. A borrower is limited to three lines, and a borrower owning more than 15 financed properties is not eligible. Large portfolios hit these walls.
Prior credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. For investment files, foreclosure history follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path.
Geography. HELOC availability is narrower than the DSCR footprint. Lendmire arranges DSCR investor loans across 41 markets, including Washington, D.C., but home equity lines are offered in a smaller set of full-service states. Confirm yours before you build a plan around one.
Payment shock. The line is variable throughout. The payment can rise with no new draw, and the shift from interest-only to amortizing repayment raises it again. Both land on you, not on the rent.
Frozen lines. Lenders can freeze or reduce a line when values fall or finances weaken. A line you are counting on for deal number four may not be there.
Subsequent draws. After closing, the minimum draw is $1,000, so plan your tranches.
Stress Test: Where the Squeeze Comes From
Here is the part most investors skip. The DSCR compares rent to PITIA, and only PITIA. Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities, and capex all sit outside the calculation. And the HELOC payment is not in the ratio either, though you still pay it out of real cash.
You are effectively financing close to the entire purchase. The rent is asked to cover the DSCR payment. Nobody asked it to cover the line.
| Scenario | What changes | Who absorbs it |
|---|---|---|
| Base case | Rent covers PITIA; line interest paid from cash flow | The rental, partly you |
| Variable-rate move | Line payment rises, DSCR payment unchanged | You |
| Vacancy | Rent stops; both payments continue | You |
| Frozen line | Next deal’s down payment disappears | Your plan |
(Honestly, vacancy plus a rising line payment in the same year is the scenario that sinks thin deals.) The investors who survive it keep reserves beyond what the lender requires and size the line to what they will use.
One more effect: a new line shows on your credit file. A DSCR purchase lender underwrites primarily on the property, so the line usually matters less there. A conventional or bank-statement lender adds the line’s payment to your personal debt-to-income. If you plan to use one of those for deal number five, count the line against it.
HELOC, Cash-Out Refinance, or DSCR Purchase Alone?
A line is one of three ways to get equity into a deal. Which one fits depends on where the equity sits and how the property is titled.
| Option | Where equity comes from | Best fit |
|---|---|---|
| HELOC | Your home or rental, via a second lien | Down payment on the next rental |
| DSCR cash-out refinance | A rental you already own | Rentals held in an LLC |
| DSCR purchase, cash down | Savings or sale proceeds | No added debt on your home |
A cash-out refinance on a standard rental goes up to about 75% LTV, and on short-term-rental collateral up to about 70% LTV. A purchase tops out at 75% on short-term rentals. Short-term rental programs also expect a 640+ score and about 12 months of hosting history. 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. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
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.
The tradeoff is simple. A line keeps your existing first mortgage in place and adds a second lien, and a cash-out refinance replaces the loan on the property. The line is flexible. The refinance is cleaner.
Which Investor Is This For?
The strategy fits three profiles well:
- You own a home with solid equity and a 700+ credit profile, and you want your first or second rental without selling anything.
- You have a paid-down rental in your own name and want to rotate its equity into the next purchase.
- You have already stabilized a rental and plan to refinance it to retire the line.
It fits poorly in these situations:
- Your rentals sit in an LLC and you do not want to retitle them.
- Your reserves are already thin.
- You are close to the exposure caps.
- Your purchase lender requires unborrowed funds.
This one is a genuine toss-up for investors with moderate equity: the line gets you into a deal now, but the carrying cost during a slow lease-up can outweigh the benefit of moving early.
Frequently Asked Questions
Can I use a HELOC on a rental I already own?
Yes, subject to lender guidelines. Investment lines run up to 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000. The title has to be held by you personally or by a revocable living trust. If the rental sits in an LLC, a vesting change or a DSCR cash-out refinance is the usual workaround.
Does the HELOC payment count against my DSCR?
No. The DSCR compares the rent to the new property’s PITIA, so the line’s payment sits outside the ratio. It still comes out of your pocket, though. A conventional or bank-statement lender would instead add it to your personal debt-to-income.
Will a DSCR lender accept a borrowed down payment?
It depends on the program. Some accept documented line proceeds, some cap the borrowed share and want seasoned cash of your own, and some require part or all of the down payment to be unborrowed. Always confirm before you draw.
How many lines can I hold, and is there a cap on my portfolio?
A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible. Combined exposure also has a ceiling, which varies by program.
What if the lender freezes my line before the next purchase?
Lenders can freeze or reduce a line when property values fall or a borrower’s finances worsen. If your next deal depends on the line, open it early, draw on a timeline you control, and keep a backup source of funds.
