The Quick Read: A home equity line of credit (HELOC) lets you borrow against equity you already own and use the cash as the down payment on a rental, so your stocks, funds, or other holdings stay invested. The line never buys the property itself. A separate acquisition loan, usually a DSCR loan, closes the purchase, and each loan has its own approval.
- The line is secured by a property you own. On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit profile and a $500,000 maximum line.
- On a primary residence or second home, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile.
- The DSCR lender checks whether the new property’s rent covers its own payment. It also has its own rule on how much of the down payment can be borrowed.
- Clearing the DSCR test does not mean the deal cash flows. You still have to cover the line payment, repairs, vacancy, and everything else.
- Which lenders fit depends on the collateral, the credit profile, the leverage you need, and the state. Lendmire is a mortgage broker that shops a wholesale network, not a lender.
Key Terms Defined
HELOC: 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 and divided by its value.
DSCR (debt service coverage ratio): The property’s monthly rent divided by its monthly payment of principal, interest, taxes, insurance, and any HOA dues (together called PITIA). A result of 1.00 means rent equals the payment.
Draw period: The stretch when you can borrow from the line and may owe only interest. A repayment period follows.
Seasoning: How long funds have sat in your account, or how long you have owned a property, before a lender counts them.
Non-QM: Loans that fall outside standard owner-occupied mortgage rules. Lenders review them on their own program guidelines, and DSCR loans are one example.
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.
Why Borrow Against Equity Instead of Selling?
Borrowing keeps your assets in place. Selling can realize gains or losses and takes money out of holdings that may keep growing. A line against real estate lets you raise cash while leaving the portfolio alone.
The tradeoff is that you take on debt and a payment. A sale does not do that. You also tie a second property to the deal, because the line is secured by the collateral property. If the new rental underperforms, that other property still carries the line.
This is why the choice is not always obvious. Selling suits some investors, borrowing suits others, and some do a bit of both. It depends on how your assets are held, what they earn, and how much monthly obligation you can carry.
Here is how the main funding routes compare.
| Route | What you give up | Main constraint |
|---|---|---|
| HELOC on a property | A new lien and a variable payment | CLTV cap, credit, DTI |
| Cash-out refinance | Your existing loan terms | Seasoning, leverage cap |
| Selling investments | Future growth on those assets | Market timing, gains or losses |
| DSCR purchase alone | Down payment from savings | Cash on hand |
A cash-out refinance replaces your existing mortgage with a larger one. It is a different tool from a line, and the DSCR cash-out refinance page covers it in full.
How the Two Loans Work Together
You need the line approved before you shop. The line is secured by a property you already own, because you cannot open a line against a property you have not bought. The sequence has five steps.
1. Pick the collateral. This is the property you already own that holds the equity.
2. Get the line approved. The lender combines every lien on that property and divides by its value to get CLTV.
3. Draw the cash and keep records. The purchase lender wants the draw traceable on your bank statements as the source of the down payment.
4. Apply for the acquisition loan. For a rental, that is usually a DSCR loan underwritten to the new property.
5. Plan the exit. Decide how the line gets paid back.
The approvals use different tests. The line is qualified largely on you: credit, debt-to-income, and the collateral’s equity. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A strong file passes both.
Which Property Do You Borrow Against?
You can borrow against your home or against a rental you already own. Many banks and credit unions write lines only on a primary residence. A BiggerPockets article on home-equity strategies notes that terms often require owner-occupancy when the line is opened. Lines on rentals generally come from different lenders.
The network treats the two cases very differently. Leverage depends on occupancy.
| Collateral | CLTV ceiling | Credit note |
|---|---|---|
| Investment property | 70% | 700 minimum; 720 and 700 both reach 70% |
| Primary residence or second home | Up to 90% | 90% only at 720 or better |
On an investment line, a score above 700 buys eligibility, not extra leverage. The 70% cap holds at every tier. Credit below 700 is not eligible for an investment line, so there is no lower tier.
A primary residence usually offers more borrowing room, but it puts your home behind the deal. A BiggerPockets discussion frames the question investors ask themselves: are you willing to risk your primary residence to buy a rental? Collateral on a rental isolates the risk, but it is capped at 70% CLTV.
What HELOC Lenders in the Network Look For
Lenders in the wholesale network differ at the edges. They agree on the core items.
Credit. The overall program floor is 600, but that floor applies to primary residences only. Investment lines require 700 or better, and 700 is a hard floor with no tier beneath it. Lenders use a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores.
Debt-to-income. The ceiling is 50%. It drops to 45% for credit profiles from 600 to 679, and a ratio above 45% requires at least 680. Because investment lines start at 700, the 45% tier never applies to them. Lenders review your file on the interest-only payment calculated on the maximum draw. A large limit therefore weighs on your ratio even if you draw little.
Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may require a second valuation, and you may request a full appraisal in any case. An investment line caps at $500,000, so it sits in that lane. Lines above $500,000 are for primary residences only, cap at 75% CLTV, and require a full appraisal. That 75% cap overrides the 90% ceiling, which applies only to primary-residence and second-home lines at a 720-or-better credit profile and only at or below $500,000.
Property type. Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) properties are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Title. The individual borrower or a revocable living trust must hold title. 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 instead.
Exposure. A borrower is limited to three lines. An investor with more than 15 financed properties is not eligible.
How the Draw and Repayment Work
A line has a draw period, when you can borrow and often pay only interest. After that, it enters repayment. The CFPB’s guide to HELOCs says the draw period may last 10 years and that many plans set minimum payments on the current balance.
Network structures are more specific. On a primary residence or second home, there are two options. One is a 3-year interest-only draw with a 17-year repayment. The other is a 5-year draw with a 25-year repayment. Investment lines run only the 5-year draw and 25-year repayment.
Three features matter for planning.
- At least 75% of the line is drawn at closing. This is not a standby line you keep untouched.
- Pricing floats through both the draw and the repayment period. It never converts to fixed, even though the CFPB notes some plans in the wider market allow a fixed option.
- After closing, the minimum subsequent draw is generally $1,000, with some state exceptions.
The line size runs from $25,000 to $750,000, with a $500,000 cap on investment property. Because of that floating structure, the payment can change even if you draw nothing more. The CFPB’s HELOC booklet lists the terms to compare, including the draw and repayment periods, adjustment frequency, and limits on how far pricing can move.
How the DSCR Lender Treats the Borrowed Down Payment
Treatment of borrowed funds varies by program. A few cap the borrowed share. The strictest overlays want part of the down payment unborrowed. Reserves are separate, and borrowed funds are often excluded from them.
DSCR compares rent to the property’s PITIA and nothing else. On a DSCR purchase, the line payment generally does not enter the ratio for the new property. That is a sharp contrast with a loan that is reviewed on debt-to-income, where the line payment is added to personal debt and can break the ratio. Some programs also review the broader debt picture, so ask the purchase lender how it treats the line.
- Purchase leverage: most files land at 75%-80% LTV (20%-25% down). Select programs reach 85% LTV on a purchase with roughly a 700+ score.
- Coverage: 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better terms and leverage.
- Credit: a 620 floor exists in parts of the network. Most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Loan size: 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.
- Reserves: these vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common.
A larger down payment lowers the monthly obligation and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The complete DSCR loans guide walks through how these pieces fit.
A Worked Picture
Picture an investor who owns a home with substantial equity. She wants a rental bought at 75% LTV on a purchase, and she wants to keep her brokerage account untouched. The rent on the new property clears roughly 1.2x coverage against its own PITIA. That passes the DSCR test. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Now stress-test the rest. The line payment sits outside the DSCR math, but she still has to pay it. Run three checks.
1. Take the rent and subtract the DSCR payment. That is the cushion before costs.
2. Subtract realistic repairs, vacancy, management, and utilities from the cushion.
3. See whether what remains, plus her other income, covers the line payment, including if pricing floats higher.
If the cushion is thin, the investor is carrying two obligations on one property’s rent. A coverage ratio above 1.00 does not make the deal cash flow positive. The ratio measures rent against PITIA only.
What Is the Exit Plan?
You need a repayment path before you draw. There are three common ones.
- Repay from rental cash flow. This works if the cushion is real and the line payment fits.
- Refinance the new property and repay the line from proceeds. A BiggerPockets discussion explains that the line does not roll into the new mortgage, and that a purchase made with line cash is technically a cash purchase. On a cash-out refinance, the network tops out around 75% LTV, and about 6 months of seasoning is the usual expectation.
- Buy, renovate, rent, then refinance. This only works if the new appraisal and the rent cooperate. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Do not assume a refinance will cover the line. The refinance depends on value and rent after you own the property.
Where the Rule Breaks
- Entire down payment borrowed. Some programs accept it. Others require part to be unborrowed.
- Gift funds versus line proceeds. They are underwritten differently. Line proceeds are your own borrowing secured by an asset.
- Unsecured borrowing. Cash advances or unsecured credit as a down-payment source are generally treated less favorably than a secured line. Ask the purchase lender first.
- LLC purchases. Funds are usually sourced to the borrowing entity or its members, subject to lender program eligibility. The line itself still cannot be titled in an LLC.
- Ineligible properties. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered.
- Availability. The home equity line is offered only in the 16 states where Lendmire provides full-service brokering. That is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
How a Broker Finds the Right Lender
Which lender fits depends on your situation: the collateral, your credit profile, the leverage you need, and the state. No single institution fits every file. A broker works with a network of wholesale lenders and matches the scenario to the program that suits it.
Before you apply, gather the following.
- The collateral property’s value estimate and all existing liens.
- Your credit profile and debt picture, because the 50% DTI ceiling applies.
- Bank statements showing where the down payment will come from.
- The target purchase’s expected rent and price, so the DSCR side is tested at the same time.
- A repayment plan for the line.
Asking questions up front saves time. Does the purchase lender accept borrowed funds? Does it cap the borrowed share? Are the funds excluded from reserves? Does the line fit within three lines and 15 financed properties?

Frequently Asked Questions
Can a HELOC cover the whole down payment?
Sometimes. Many programs in the network accept borrowed funds for the down payment and closing costs. A few cap the borrowed share, and the strictest overlays want part of the down payment unborrowed. Reserves are a separate test, and borrowed funds are often excluded from them. Check the purchase lender’s rule before you draw.
Is it better to borrow against my home or a rental?
It depends on leverage and risk. A primary residence can reach 90% CLTV, but only at a 720-or-better credit profile. An investment property caps at 70% CLTV, with a 700 minimum and a $500,000 maximum line. A line on your home puts your home behind the deal, while a line on a rental limits the exposure to the investment collateral.
Does the line payment hurt my DSCR?
Generally not on the new property, since DSCR compares that property’s rent to its own PITIA. The payment still has to come from somewhere, though. On a loan that is reviewed on debt-to-income, the line payment is added to your personal debt and can break the ratio. Some programs review the broader debt picture, so confirm with the lender.
Can I take the line in an LLC?
No. A property already in an LLC needs a vesting change, or a DSCR cash-out instead. Purchases through an LLC on the DSCR side are subject to lender program eligibility.
What if my coverage falls below 1.00?
Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Many select programs start at 1.00. A thin ratio also makes it harder to carry the line payment, so stress-test the whole structure first.
