The Quick Read: It depends, and it is smart mainly when the new rental’s own income can carry its first mortgage while you also carry the equity loan, when the lien sits on collateral you can afford to put at risk, and when the line’s adjustable pricing and draw period fit how long you plan to hold. Across the wholesale network Lendmire works with, the files that go well treat the equity loan as a bridge with an exit plan. The files that struggle treat it as free money.
- A home equity loan stacks a second payment on top of one rent check.
- On an investment property, equity lines in the network cap at 70% combined loan-to-value (CLTV) and $500,000.
- A DSCR above 1.00 does not mean the property cash-flows after the second payment.
- Often the better tool is a DSCR cash-out refinance or a larger down payment on a smaller deal.
Which Loan Do People Actually Mean?
The question hides two different loans, and the risk is very different for each. One borrows against the home you live in to fund a rental. The other borrows against a rental you already own.
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.
| Item | Borrow against your home | Borrow against an existing rental |
|---|---|---|
| Collateral | Your primary residence | The rental property |
| Main risk | Losing your home | Losing the rental |
| Typical use | Down payment on the next rental | Reserves, repairs, next purchase |
| Title rule | Individual or revocable trust | Same; LLC titling is a problem |
The first is the more common plan. It is also the one that puts the most personal downside on the table. If a rental stumbles, the lender’s claim is on your house.
How Does the Equity Loan Fit Next to the Rental’s Own Mortgage?
The two loans are underwritten separately, and the equity loan is judged on you. With an existing first mortgage, a home equity loan or line becomes a second mortgage paid in addition to the first, as the CFPB’s explainer on home equity loans and HELOCs describes. A home equity loan is a lump sum. A line of credit lets you draw up to a limit.
The rental purchase is a different file. 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.
DSCR qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio compares rent to the property’s own principal, interest, taxes and insurance (PITIA). It does not know your equity line exists.
That gap matters. A property can clear the ratio and still lose money each month once the equity payment lands on top. The ratio also ignores repairs, vacancy, management, utilities and capex. Clearing 1.00 is not positive cash flow. Not even close, on a thin file.
Borrowed down-payment funds raise their own questions. Whether a given lender accepts them, and what paper trail it wants, varies by lender, leverage and loan size. Brokers placing these files see the same pattern: the draw is treated as borrowed money, so the cleaner the paper trail from line to closing account, the fewer surprises. Confirm the sourcing rules for your target lender before you draw, not after.
When Is It Smart, and When Isn’t It?
It is smart when the rental clears coverage with room to spare, you hold real reserves, and the equity loan has a defined exit. It is not smart when the new property only works if everything goes right. Use these as decision criteria rather than a pros-and-cons list.
It tends to make sense when:
- The rental clears its first mortgage with a cushion, not just a pass.
- Your primary residence has meaningful equity left after the line, and the loan size is modest relative to it.
- You plan to repay the line within a defined window, such as after a refinance on the new property.
- Your reserves could cover several months of both payments without help from the rent.
- You are weighing the line against the alternative of waiting and saving, and the property’s value to you justifies the added debt.
It tends to be the wrong call when:
- The purchase only pencils at near-100% financing, leaving no equity cushion.
- You are reaching for the line because the deal barely qualifies. That is a signal to re-examine the deal, not the funding source.
- Your own household budget cannot absorb the line if the rental sits vacant.
- The line’s payment is meant to be paid from the rental’s rent, and the rent has no spare margin.
Honestly, the middle case is a toss-up. A solid property with a thin cushion can work for an investor with strong reserves and a short hold on the line. The same property is a poor bet for someone with one income and a mortgage already stretched.
BiggerPockets carries a lender’s warning that a HELOC is not meant to be permanent financing, with the maturity date and the adjustable pricing as the usual trouble spots. That matches what brokers see on the borrower side.
What Do the Numbers Look Like Under Stress?
Run the numbers on a modeled purchase at 75% LTV, with rent covering the first mortgage at about 1.20x. These are assumptions for illustration, not market data. The equity line’s payment sits outside the ratio, so the ratio looks healthier than your actual monthly picture. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
| Case | Modeled coverage | Read |
|---|---|---|
| Base | About 1.20x | Passes with a modest cushion |
| Rent down 10% | About 1.08x | Passes, but little room left |
| Rent down 15% | About 1.02x | Barely clears 1.00x |
| Rent down 20% | About 0.96x | Below 1.00x on rent alone |
Now add the equity line. If the line funded the 25% down payment, the purchase runs near 100% financing. That means no equity cushion in the new asset, plus the line’s adjustable pricing on top. A rent dip, a vacancy and a repair bill can land in the same quarter. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
If a purchase lands below 1.00x, structures may exist that a lender would review. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted. Interest-only periods and extended terms through select lenders may help in some cases. Qualification stays subject to lender guidelines, credit approval and property review.
If the stress case only works with a sub-1.00 structure plus a line at near-100% financing, step back. The deal is telling you something.
What Do Equity Lines Allow Through Lendmire’s Network?
On an investment property, the network’s equity line tops out at 70% CLTV and $500,000, with a 700 minimum credit score. Credit above 700 buys eligibility, not extra leverage, since the 700 and 720 tiers both sit at 70% CLTV. Programs are brokered through select wholesale partners, and figures are subject to lender guidelines and full file review. Availability runs through Lendmire’s 16 full-service states, narrower than its DSCR footprint of 41 markets, including Washington, D.C.
On a primary residence or second home, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile. Don’t plan around the top tier unless your file fits it.
Structure matters for planning:
- Draw and repayment. Primary-residence lines offer either a 3-year interest-only draw followed by a 17-year repayment, or a 5-year draw followed by 25 years. Investment lines run the 5-year draw and 25-year repayment structure only.
- Funds drawn at closing. At least 75% of the line is drawn at closing. This is not a stand-by reserve you leave untouched.
- Pricing. It floats through the draw and the repayment period and never converts to fixed.
- Debt-to-income. The maximum is 50%, calculated on the interest-only payment at the full draw.
- Valuation. Lines at or below $500,000 ordinarily use automated valuation with no traditional appraisal. You can request a full appraisal.
- Property types. Single-family, 2-4 units, PUDs, townhomes and condominiums. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural properties are not offered.
- Title. The individual borrower or a revocable living trust. An LLC cannot hold title on the equity line, subject to program terms.
- Exposure. Three lines per borrower, and a borrower with more than 15 financed properties is not eligible.
The title point catches portfolio investors. A rental already deeded to an LLC needs a vesting change before it can carry an equity line. Often a DSCR cash-out refinance is the cleaner route. Lendmire’s home equity loan rental property covers that fork in more depth.
The Risks Nobody Budgets For
The biggest risk is not the second payment. It is the stack. Primary mortgage, equity loan and rental mortgage all draw on one household’s cash flow. A single disruption, such as a job change, a long vacancy or an unexpected capex bill, can cascade across all three.
The CFPB’s HELOC booklet lays out the mechanics. A line lets you borrow, spend and repay as you go with your home as collateral. Falling behind could cost you the home. Some lines carry a balloon payment, and the payment can jump when the draw period ends. Some lenders waive up-front costs and others charge fees, such as an appraisal.
Other risks come up on real files:
- Lien position. A line on a property with a first mortgage sits in second position. Refinancing the first later can require subordination.
- Future borrowing room. The line counts against your debt-to-income on the next purchase.
- Selling. Selling the home often forces repayment of the home equity debt.
- A shrinking cushion. If values dip while a line is fully drawn, the combined balance can sit above what a refinance supports.
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.
How Does It Compare to the Alternatives?
Several other paths reach the same goal. The comparison below uses network figures and labels each by transaction and occupancy.
| Option | Collateral | Leverage ceiling | Reviewed on |
|---|---|---|---|
| Equity line on primary home | Your residence | Up to 90% CLTV at 720+ | You (credit, DTI) |
| Equity line on a rental | The rental | 70% CLTV, $500K max | You (700+ credit, DTI) |
| DSCR cash-out refinance | The rental | About 75% on standard rentals | Property rent vs. payment |
| DSCR purchase, bigger down | The new rental | 75-80% on a purchase | Property rent vs. payment |
On a DSCR purchase, most files land at 75%-80% LTV, and select programs reach 85% LTV with roughly a 700 score or better. On a cash-out, the network tops out near 75% LTV on standard rentals, with about six months of seasoning as the common expectation. Coverage of 1.00x is where select programs start, and stronger ratios open better pricing and leverage. Most programs want a credit score near 660, and a 620 floor exists in parts of the network.
The advantage of a DSCR cash-out is structural. It is secured by the rental, not your home, and it is reviewed on the property’s rent rather than your personal debt-to-income. The tradeoff is that it replaces your existing first mortgage, which only helps if the new terms work for you. If you hold an LLC portfolio, DSCR is typically the only lane that works. For a single rental owned personally with strong household income and a low existing first mortgage, a line may carry less friction.
Using a larger down payment is the plain-vanilla alternative. It lowers the payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules or property eligibility. Reserves vary by lender, leverage and loan size, commonly around six months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up. The strongest files clear both tests: enough equity and enough rental coverage.
For the wider picture of how these loans work, Lendmire’s complete DSCR loans guide is the place to start.
Before You Apply
Settle these questions before any application:
1. How much would the property cover on rent alone, after the first mortgage?
2. If the line funds your down payment, what is the combined financing on the new asset?
3. Who holds title today, you personally or an entity?
4. What is your exit plan for the line, and by when?
5. Could your household carry all three payments through a vacancy?
6. Does your target lender accept borrowed down-payment funds, and what paper trail does it want?

DSCR: Debt service coverage ratio, meaning the rent divided by the property’s monthly obligation.
Seasoning: The time you must hold a property or loan before a lender will count it.
Vesting: The legal form in which title is held, such as an individual or a trust.
Frequently Asked Questions
Is it smart to use a home equity loan as the down payment on a rental?
Only when the rental can carry both its own mortgage and the equity payment with room to spare. Using the equity line near 100% financing leaves no cushion in the new asset. It tends to fit a short hold with a defined exit, such as a refinance that repays the line, better than a long hold.
Can I take an equity line on a rental held in an LLC?
Generally no. On this network the line requires title in the individual borrower’s name or a revocable living trust. A rental deeded to an LLC needs a vesting change or a DSCR cash-out instead, subject to lender program eligibility. For the broader question, see Lendmire’s piece Can You Get A Home Equity Loan On Rental Property.
How much can I borrow against an investment property?
On an investment property, the network’s ceiling is 70% CLTV with a $500,000 maximum line and a 700 minimum credit score. A line above $500,000 applies only to primary residences. Valuation on lines at or below $500,000 ordinarily runs on automated valuation.
Does the equity line payment count in the DSCR?
The ratio compares the new property’s rent to its own PITIA, so the line sits outside it. How a given lender treats borrowed funds and your overall file varies, so confirm before you draw. Either way, the payment still comes out of your real cash flow.
What if rents fall after I buy?
Then the equity payment keeps coming while coverage shrinks. In the stress table above, a 20% rent drop takes a 1.20x property below 1.00x on rent alone. Hold reserves for exactly that scenario before taking on a line.
