The Quick Read: A home equity line does not buy a rental. It produces cash that becomes your down payment, while a separate investor loan buys the property. The plan works only if the line, the purchase loan, and the rent can each carry their own weight. Lenders review the line and the purchase loan separately, and each has its own rules.
- On an investment property, the line tops out at 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a $500,000 maximum line.
- A line on your primary residence can reach higher, but the 90% CLTV ceiling exists only at a 720-or-better credit profile.
- The line has to be open and funded before you go under contract, and at least 75% of it is drawn at closing.
- The DSCR on the purchase loan leaves out the line’s payment, but your bank account still pays it.
- Lines go to individuals or revocable living trusts. An LLC cannot hold title.
Where the Cash Comes From
Most investors who pair a line with a purchase use one of two structures. Know which one you are in, because the underwriting differs.
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.
Structure A: the line sits on your primary home. You borrow against the equity in the house you live in, then use the cash toward a rental. The line’s collateral is your home. The rental is a separate property with its own loan.
Structure B: the line sits on a rental you already own. The older rental’s equity funds the next one. The line is an investment-property line, and it carries tighter terms than a primary-residence line.
Either way, the line is debt. Borrowed down-payment money is not savings, and it is not free equity. It has to be repaid, and a lender can see it as a new obligation.
Lendmire is a mortgage broker, not a lender. It places home equity lines through select wholesale partners, in 16 states. Every figure below is subject to lender guidelines and a full file review.
What the Network’s Lines Look Like
Ceilings depend on how the property is used. Here is the side-by-side.
| Occupancy | Max CLTV | Min credit | Max line |
|---|---|---|---|
| Primary residence | 90% (720+ only) | 600 | $750,000 |
| Second home | 90% (720+ only) | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
Read that table carefully. The 90% figure applies only to a 720-or-better profile and only on a primary residence or second home, and it applies on lines up to $500,000. A primary-residence line above $500,000 caps at 75% CLTV and needs a stronger credit profile and a full appraisal. Lines at or below $500,000 usually run on an automated valuation instead.
An investment-property line has no higher tier. The ceiling is 70% CLTV, and the line cannot exceed $500,000 in total.
Other mechanics matter just as much:
- Structure. The line is a standalone first- or second-lien loan. On primary residences and second homes, two draw structures exist: 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.
- Cost behavior. The cost of the line floats through the draw and the repayment period. It never converts to a fixed structure.
- Draw at closing. At least 75% of the line is drawn at closing. This is not a line you leave untouched and tap later. Most of the interest clock starts on day one.
- After closing. The minimum subsequent draw is $1,000 on the structure that states one.
- Debt-to-income (DTI). The maximum is 50%, or 45% for credit profiles from 600 to 679. A ratio above 45% needs a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to draw.
Market surveys show a different picture. NerdWallet reports a typical market structure of a 10-year draw followed by repayment of up to 20 years, and DTI limits of 40% to 50% on investment-property lines. Those are market-wide figures. The network figures above are the ones that apply to a file placed here.
How Underwriting Treats the Line, Step by Step
Step 1: The equity math
The lender takes the property’s value, applies its CLTV cap, and subtracts every existing lien. The CFPB’s home equity line booklet describes the same basic formula: a percentage of appraised value, less what you still owe.
Picture an investor with a 700 score whose primary home carries a first mortgage equal to 60% of its value. A tier that allows 85% CLTV on a primary-residence line up to $500,000 leaves room worth 25% of the home’s value. If the rental costs about what the home is worth, that room matches the 25% down payment on a purchase at 75% loan-to-value. It leaves nothing for closing costs or reserves. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Now run the same idea on an older rental. Say it carries a first mortgage at 40% of value. The investment ceiling of 70% CLTV leaves room worth 30% of its value, capped by the $500,000 maximum line. Credit must be 700 or better.
Step 2: The line is underwritten to you
The line looks at your credit, your DTI, and your equity. It does not primarily look at the rental you plan to buy. Lenders also review repayment ability: income, debts, and credit history.
A few file rules apply. The credit report can be no more than 90 days old at closing. The score model is a single-bureau score keyed to the primary wage earner. Housing history is checked across all financed properties. A borrower cannot own more than 15 financed properties and is limited to three lines.
Step 3: You draw the cash
Under the CFPB’s description of a home equity line, you can borrow repeatedly up to your limit during the draw period, and you could lose your home if you fall behind. On this network, most of the line is drawn at closing anyway.
Sequencing matters. The line has to be open and funded before you go under contract on the purchase. The funds should sit in your account, seasoned and documented. Don’t bet a contract on a line that has not closed.
Step 4: The purchase lender reviews the new loan
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.
On a purchase, most files across the wholesale network land at 75% to 80% loan-to-value, meaning 20% to 25% down. Select programs reach 85% LTV (15% down), generally with a score near 700 or better. Credit floors run from 620 in parts of the network to around 660 on most programs, and 700 or better unlocks the strongest tiers. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. You can read the mechanics in Lendmire’s complete DSCR loans guide.
Here is the catch for this article. Whether a lender accepts borrowed funds for the down payment is program-specific. Some lenders in the network do, others do not, and some limit it. Confirm this before you open the line, not after.
Step 5: You carry both payments
The DSCR ratio compares rent to the purchase loan’s payment (principal, interest, taxes, insurance, and any HOA dues). It leaves out the line. Your line’s interest-only payment still leaves your account every month.
A DSCR above 1.00 also does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. A rental that clears 1.25x on the purchase loan can still feel thin once the line’s payment comes out of the same rent.
Where the General Rule Breaks
Most of the above works as described. These edge cases change the outcome.
A rental held in an LLC. Lines go to individuals and revocable living trusts only. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If a rental is already deeded to an LLC, you need to change the vesting or use a DSCR cash-out refinance instead. A DSCR loan can often be made to an LLC, subject to program terms. This is the sharpest structural difference between the two products.
A recently bought rental. A property purchased at typical investor leverage has little equity room. The line usually has to sit on your primary home or an older rental.
Converting a home to a rental. A line opened on a home you live in assumes you live there. Renting it out later can conflict with the line’s terms. Disclose your plan to the lender before you convert.
Lien position. A DSCR loan generally needs first-lien position on the subject property. A line sitting on a rental you now want to refinance has to be paid off or restructured first, depending on the lender.
Reserves. Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around six months of PITIA (principal, interest, taxes, insurance, and association dues). Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about nine months. Borrowed money typically does not count as reserves, because it is debt, not an asset.
A line that gets frozen. Lenders can freeze or reduce lines if values fall or your finances worsen. Don’t plan a purchase around draws you have not yet taken.
Ineligible property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible for the line. Single-family, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable) are. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered at all.
Listed properties. A property listed for sale, or within the past 60 days, is ineligible in several states. Check this before you apply.
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.
Line or Cash-Out Refinance? (Choose the Right Tool)
A line on one property is not the only way to pull equity. A DSCR cash-out refinance on the rental itself is the main alternative.
| Factor | Investment-property line | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Borrower credit, DTI, equity | Rental income vs. payment |
| Leverage ceiling | 70% CLTV | 75% standard rentals; 70% STR |
| Cost behavior | Floats, never fixed | Fixed spine; ARM available |
| Title | Individual or revocable trust | LLC possible per program |
| Seasoning | Varies by file | About 6 months common |
The cash-out route has its own rules. Coverage of 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. Cash-out leverage tops out around 75% on standard rentals and 70% on short-term-rental collateral.
Lendmire’s walkthrough on using a home equity line for investing covers the broader strategy side of this choice.
Neither tool is better in every case. The line is a good fit when your credit is strong and you hold equity in a home you plan to keep as a home. The cash-out is the stronger play when the rental has built up equity and you want the debt tied to the property that earns the income. Honestly, many investors end up doing both, just at different times.
The Real Cost: Two Debts, One Plan
Using a line for the down payment pushes your combined leverage toward 100% of the purchase price. Your home or older rental becomes collateral for the debt that bought a different property.
Stress-test three things before you sign:
1. A moving payment. The line’s cost floats, and a stable payment today can look different later.
2. The repayment step-up. On an investment line, the 5-year interest-only draw ends and a 25-year full repayment begins. The payment jumps. Ask whether the rental will be stabilized by then.
3. An empty unit. Run the plan with the rental vacant for a stretch. Rent must carry the purchase loan, and your own cash must carry the line.

Common Mistakes
- Opening the line after going under contract. Funds need to be seasoned and documented first.
- Assuming the whole line is optional. At least 75% is drawn at closing.
- Counting the line as a reserve. It is debt, not an asset.
- Ignoring the DTI test. The lender reviews your file on the interest-only payment at the maximum draw.
- Forgetting title. An LLC cannot hold the line’s collateral.
- Treating DSCR above 1.00 as profit. It is a coverage test, not a cash-flow forecast.
Key Terms Defined
HELOC (home equity line of credit): A revolving loan secured by your property. You borrow against its equity as needed, up to a limit.
Equity: What a property is worth minus what you owe on it.
CLTV (combined loan-to-value): All loans on a property added together, divided by its value.
Draw period: The stretch when you can borrow and pay interest only. Repayment of principal follows.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly payment. It measures whether the rent covers the loan.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the full monthly payment counted in the DSCR.
Seasoning: The waiting period a lender wants between two events, such as buying a property and refinancing it.
Lien position: Whether a loan is first or second in line to be repaid if the property is sold or foreclosed.

Frequently Asked Questions
Can I use a HELOC for the down payment on a DSCR loan?
Sometimes. Whether the purchase lender accepts borrowed down-payment funds depends on the program, the lender, and your file. Lines also have to be open and funded before you go under contract. Confirm acceptance first, then open the line.
Does the HELOC payment count in the DSCR?
No. The DSCR compares rent to the purchase loan’s payment only. The line’s payment still comes out of your cash, so a passing ratio can still leave thin monthly cash flow once you add the line.
Can I take a line on a rental held in an LLC?
Not directly. Lines go to individuals or revocable living trusts. A property deeded to an LLC needs a vesting change, or a DSCR cash-out refinance can pull the equity instead, subject to program terms.
How much can I borrow against a rental I already own?
On an investment-property line, up to 70% combined loan-to-value, to a $500,000 maximum line, with a 700 minimum credit score. Your existing mortgage counts against that 70%.
Can the lender freeze my line after I open it?
Yes. Lenders can freeze or reduce a line if the property’s value falls or your finances worsen. That is why you draw and document the funds before you go under contract, not after.
