The Quick Read: A home equity line secured by a rental works when you hold real equity in that rental, your purchase loan accepts borrowed cash, and your whole portfolio can carry both payments without leaning on the new rental to bail you out. The line supplies cash only. A separate loan, usually a DSCR loan, buys the new property, and each loan is approved on its own terms.
- On Lendmire’s wholesale network, a line on an investment property reaches up to 70% CLTV, from $25,000 to $500,000, with a 700 minimum credit score.
- The line is reviewed on your credit, income, and debt-to-income ratio, not on the rent the property earns.
- The purchase loan compares the new rental’s rent to that property’s own payment. The line’s payment never enters that ratio, but you still pay it every month.
- Purchase programs treat borrowed down payments three ways: some accept them with documentation, some cap the borrowed share, and some want part of the down payment to be your own cash.
- The strategy fits a rental with a modest first mortgage. A property bought recently at high leverage usually has no room left.
Equity-funded rental growth is simple on paper and fussy in practice. The fussy parts are who owns the title, how much of the line you must draw, and what the purchase lender does with borrowed money. This guide walks through each one.
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 Approvals
Two separate lenders review two separate files. The line looks at you and the collateral. The purchase loan looks at the new rental. Nothing about one loan’s approval carries over to the other.
Picture the sequence. You own a rental with a lot of equity. You open a line against it and draw cash into your own account. You then offer on a new rental, and a DSCR lender reviews that property. The DSCR lender is not asking how you got the cash, at least not at first. It wants to know that the cash is yours, that it was documented, and that the new property’s rent covers its own payment.
Experian says a HELOC on an investment property can fund renovations, repairs, or another real estate investment. That matches how brokers use the product. The line is a source of cash. It is not a way to buy a property.
Key Terms Defined
HELOC: A home equity line of credit, a revolving credit line secured by property you already own.
CLTV: Combined loan-to-value, which adds every loan on the property and divides by its value.
Draw period: The stretch of time when you can borrow from the line, usually with interest-only payments.
DSCR: Debt service coverage ratio, which is monthly rent divided by the property’s monthly PITIA.
PITIA: Principal, interest, taxes, insurance, and any association dues, which together make up the full monthly housing payment.
Automated valuation: A computer-generated property value used in place of a full appraisal.
Which Property Should Secure the Line?
You have two choices. You can borrow against your primary home, or you can borrow against an existing rental. Both can put cash in your account. They carry different risks and different limits.
| Factor | Line on your home | Line on a rental |
|---|---|---|
| Collateral at risk | Your residence | The rental |
| Network CLTV ceiling | Up to 90%, at 720+ credit only | 70% on an investment property |
| Minimum credit | Varies by occupancy | 700, with no tier above it |
| Valuation | Automated at or below $500,000 | Commonly automated, no full appraisal |
The home-secured line stretches further. It also puts the place you live behind your investing plans. That is the trade, and only you can price it. A line on a rental keeps the risk inside the portfolio, but it caps out at 70% CLTV and fewer banks write it.
Availability is real. In a BiggerPockets discussion, an investor describes calling several lenders before finding one that would lend against a rental. Lendmire’s network offers the rental-secured line in 16 full-service states, which is narrower than the 41 markets where its DSCR loans are available.
How Underwriting Treats the Line, Step by Step
The line is underwritten on credit, income, and DTI. The rent from the property does not raise the line. Here is the order the investor works through.
1. Measure usable equity. Take the property’s value, multiply by the CLTV cap, and subtract every existing lien. That is your ceiling.
2. Check the other two limits. The usable line is the smallest of three numbers: CLTV room, the $500,000 program cap, and what your DTI allows.
3. Apply and close the line first. The line is never closed together with the purchase. It exists before you make the offer.
4. Draw into your own account. Keep the draw documented. The purchase lender will ask to see where the cash came from.
5. Ask the purchase lender about borrowed funds. Down payment, closing costs, and reserves are three separate pots, and each can be treated differently.
6. Close the new rental on its own loan. Then pay the line down from rent, savings, or a later refinance of the new property. Closing on the rental does not pay the line off.
Here is what the sizing looks like in percentages. Say your first mortgage sits at 50% of the property’s value. With a 70% CLTV ceiling, about 20% of value remains for the line. A leveraged rental hits the percentage limit first. A high-value rental with little debt hits the $500,000 cap first. DTI can bind before either one, because the network qualifies the line on the interest-only payment calculated on the maximum draw, with a 50% DTI ceiling.
The Investment Line’s Ground Rules
A few mechanics shape every decision, so read them before you commit.
- Structure: A standalone line in first or second lien position. Investment lines run a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period.
- Draw at closing: At least 75% of the line is drawn at closing. Size the line to the cash you need, because interest accrues on what you draw.
- Pricing behavior: The line floats during both the draw and repayment periods, and on this network it never converts to fixed.
- Credit: A 700 minimum. Scores above 700 keep you eligible but do not raise the 70% ceiling.
- Title: Held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
- Exposure limits: Up to three lines per borrower. Anyone with more than 15 financed properties is not eligible.
- Eligible properties: Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
- Valuation: Because the line caps at $500,000, it normally runs on an automated valuation, with no traditional appraisal.
- Listing status: In several states, a property listed for sale or listed within the past 60 days is ineligible.
Market structures differ. Experian describes a typical 10-year interest-only draw followed by 10 to 20 years of repayment, and it reports that lenders across the market typically cap investment-property loan-to-value at 80%. The network’s ceiling on an investment property is 70% CLTV. Treat the market figures as background only.
The CFPB explains that many lines allow part of the balance to convert to a fixed rate. That option exists across the broader market. The network’s investment line does not offer it.
How the Purchase Lender Treats the Cash
The DSCR purchase loan cares about two things: the new property’s rent coverage and the source of your down payment. Most purchase files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select high-leverage programs reach 85% LTV on a purchase, which means 15% down, typically for scores of about 700 and above. No zero-down DSCR purchase exists.
DSCR compares rent to PITIA only. For many select programs, 1.00 is where coverage starts. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage. The rest of the picture sits in the complete DSCR loans guide.
Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. Your HELOC payment sits outside it too, which is where investors get lulled. The ratio can look healthy while your real monthly picture is tight.
Borrowed funds split three ways across the network:
- Some programs accept documented borrowed funds for the down payment.
- Some cap the borrowed share.
- Some want part of the down payment unborrowed.
Reserves are a separate test. They commonly run around 6 months of PITIA, and many programs exclude borrowed funds from reserves even when they accept them for the down payment. Reserve rules vary by lender, leverage, loan size, and transaction type. Ask about all three pots before you draw a dollar.
The Benzinga overview lists the documents lenders usually want on an investment-property line: proof of income, tax returns, rental agreements, and proof of insurance. On the purchase side, expect to show the draw and prove that funds cover the down payment, closing costs, and reserves.

Where the General Rule Breaks
The general rule is that equity in one rental can fund the next. These situations bend it.
A recently bought rental. A rental purchased at 75% to 80% LTV on a purchase starts above the 70% CLTV ceiling on an investment line. It has no room until the balance drops or the value rises. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A property in an LLC. Once a rental is deeded to an LLC, the line cannot use it as collateral. A DSCR loan can close in an LLC name, subject to lender program eligibility. A property already in an LLC needs a vesting change or a DSCR cash-out refinance instead.
A fully borrowed down payment. This can fail on that basis alone, even when rent coverage is strong. It also leaves you financing nearly the whole price, so a vacancy stretch hits harder.
A foreclosure purchase. One investor reported that a property bought at foreclosure could not carry a line for at least six months at their bank. That is one investor’s account, not a rule. It does show that title seasoning can matter.
A bank that limits you to one line. Some lenders allow only a single investment property. The network allows up to three lines per borrower.
Variable payments on a long hold. The line floats, so its payment can drift away from what you modeled. Many investors treat it as a bridge rather than permanent financing.
Divorce. In many states, a pending case can hold the usable amount at zero until the spouse consents in writing or a court allows the draw.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered on the DSCR side either.
When It Makes Sense (and When It Doesn’t)
Run the decision against your situation, not a general rule.
| Situation | Fit |
|---|---|
| Strong first mortgage, low CLTV on the rental | Good |
| Cash-short, equity-rich, buying one more rental | Good |
| Purchase lender accepts borrowed down payment | Good |
| Rental bought recently at high leverage | Poor |
| Portfolio runs thin after vacancy | Poor |
| Plan depends on the new rental’s rent to pay the line | Poor |
The strongest case is an investor with a good existing first mortgage who wants to keep it. A line leaves that loan untouched. A cash-out refinance replaces it. If the existing loan is strong, the line avoids disturbing it.
The weakest case is the plan that works only if everything goes right. If a single vacancy turns the portfolio negative, the line is adding fragility, not growth.
Consider a modeled scenario, not a market figure. You own a rental with a first mortgage at 50% of value. An investment line on this network caps at 70% CLTV, which leaves about 20% of value in line room. You plan a purchase at 75% LTV, so you need 25% down, plus closing costs and reserves. Dividing 20 by 25 shows the new rental’s price would need to be about 80% of the old property’s value or less, before closing costs and reserves. Because at least 75% of an investment line is drawn at closing, you would also start paying on most of that amount right away, so the practical room is tighter than this arithmetic suggests. Past that, you need other cash. Then ask whether the new rental’s coverage clears roughly 1.2x on its own and whether your other rentals can carry the line’s variable payment through a vacancy. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
When the line has to fund everything, the file gets thin fast. Savings that cover reserves leave the borrowed cash with one job, the down payment.
HELOC or DSCR Cash-Out Refinance?
A cash-out refinance replaces the first loan and is reviewed on rent coverage. A line leaves the first loan in place and is reviewed on you. Neither is better in general.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Credit, income, DTI | Property rent coverage |
| Ceiling | 70% CLTV, investment property | Around 75% LTV, standard rental |
| Original first loan | Stays in place | Replaced |
| Seasoning | Varies by lender | About 6 months common |
| Payment behavior | Floats, interest-only draw | Fixed spine, IO available select |
A cash-out refinance can make sense when the first loan is weak or when you want a fixed structure. A line can make sense when the first loan is strong. Ask which loan you are protecting.
Pre-Draw Checklist
Run through this before you close the line.
- Confirm the rental’s equity under the 70% CLTV cap, after every lien.
- Confirm the title is in your name or a revocable trust.
- Ask the purchase lender how it treats borrowed funds in each of the three pots.
- Confirm the rental is not listed for sale, and has not been within the past 60 days.
- Stress your whole portfolio for vacancy, then for a larger variable payment.
- Write down how the line gets repaid: rent, savings, or a refinance of the new property.
Payment shock is the part many people skip. The CFPB notes that monthly payments are often much higher once the repayment period starts, and that borrowing stops at that point. On this network’s investment structure, the interest-only draw lasts 5 years, then the 25-year amortizing repayment begins. Plan your exit before the draw period ends.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Can a HELOC cover the whole purchase of a rental?
Not in a clean way. A DSCR purchase loan still wants a down payment of 20% to 25% on most files, and no zero-down DSCR purchase exists. Many programs also cap or reject a fully borrowed down payment, and reserves often must come from your own cash.
Does the HELOC payment lower the new rental’s DSCR?
No. The purchase loan reads the new property’s rent against that property’s own PITIA. The line’s payment never enters the ratio. It still comes out of your cash flow every month, which is why the ratio can look fine while the portfolio feels tight.
Does the rent from my rental raise the line?
No. The line is underwritten on credit, income, and DTI, not on the property’s rent. Credit above 700 does not raise the 70% CLTV ceiling either. It only keeps you eligible.
Can my LLC take out an investment property HELOC?
No. Title must sit with you personally or in a revocable living trust. A DSCR cash-out refinance is usually the route for an LLC-owned rental, subject to lender program eligibility.
Is a HELOC a long-term way to hold a rental?
Many investors treat it as a bridge. The line floats, so the payment can drift from your model, and the draw period ends. Plan the exit before you draw, whether that is a later refinance of the new property or paydown from savings.
