The Quick Read: You borrow against the equity in a rental you already own, move the cash into your own account, and put it toward the next purchase. It works only when the new lender accepts borrowed funds and the new property can carry its own payment. Treatment of borrowed down-payment money varies by program, so confirm it before you draw.
- On Lendmire’s network, a line secured by an investment property tops out at 70% combined loan-to-value (CLTV), with a 700 minimum credit profile and a $500,000 maximum line, subject to lender guidelines.
- You will carry two obligations at once: the new mortgage and the line, which is borrower-level debt.
- A line used for the whole down payment leaves you near 100% financed on the new property.
- Clearing a rent test on the new property does not mean the deal cash-flows. Repairs, vacancy, and management sit outside that test.
Key Terms Defined
HELOC (home equity line of credit): A revolving credit line secured by property you own, which you borrow from as needed up to a set limit.
CLTV (combined loan-to-value): All loans secured by the property, added together, divided by its value.
Draw period: The stretch when you can borrow from the line. On Lendmire’s investment lines, it runs five years.
Repayment period: The stretch after the draw period when you can no longer borrow and the balance amortizes. On investment lines it runs 25 years.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s monthly payment. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the payment a DSCR test compares rent against.
Seasoning: How long money has sat in your account, or how long you have owned a property, before a lender counts it.
Source of funds: The paper trail showing where your down-payment money came from.
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.
What Does an Investment Property HELOC Actually Do Here?
It converts rental equity into cash you control, without selling the rental or refinancing its first mortgage. Your existing loan stays in place. The line sits behind it in second position, or in first position if the rental is free and clear.
Here are the network’s investment-line terms. Every figure is subject to lender guidelines and a full file review.
- Leverage: The ceiling is 70% CLTV. Credit at 720 and credit at 700 both reach it, so a higher score buys eligibility, not extra leverage.
- Credit: 700 is the floor. There is no tier beneath it.
- Line size: From $25,000 up to $500,000. Anything larger is available only on a primary residence.
- Structure: A five-year draw followed by a 25-year repayment. At least 75% of the line is drawn at closing.
- Pricing: It floats through both phases and never converts to fixed.
- Valuation: Lines at or below $500,000 usually run on an automated valuation, so a traditional appraisal is uncommon. You can still request one.
- Debt ratio: 50% maximum DTI, tested on the interest-only payment at the maximum draw.
Market surveys report rental-property lines reaching 80% loan-to-value, according to Experian. That describes the broader market. On this network, an investment-property line stops at 70% CLTV.
Experian also notes that rental-secured lines are harder to qualify for than lines on a primary home. That matches what brokers see: fewer lenders, tighter credit floors, lower ceilings.
Lendmire arranges these through select wholesale partners and is never the lender. Availability is limited to its 16 full-service states, which is narrower than its 41-market DSCR footprint.
How Do Lenders Treat the Money, Step by Step?
Two separate underwriting files run side by side. One decides whether you get the line. The other decides whether the purchase lender accepts the cash. Treat them as independent gates.
1. Pick the collateral. The line can sit on a rental or on your own home. The choice changes your ceiling, your risk, and your paperwork (see the comparison below).
2. Qualify the line. This is borrower-level underwriting: equity, credit, and debt-to-income. The line’s lender never looks at the new property.
3. Open the line before you shop, not after. Sellers want proof of funds with your offer. One BiggerPockets investor describes going under contract before the first line statement even arrived, which is a tight way to run it.
4. Draw and move the cash into your own account. Keep the line agreement, the draw statement, and the deposit record. A dedicated account makes the trail easier to read.
5. Disclose the source to the purchase lender. Undisclosed borrowed funds are a classic way to derail a file. Ask before you draw whether the program accepts them.
6. Purchase underwriting. On a DSCR purchase, the new property’s rent is tested against its own payment. The line payment generally sits outside that ratio. It still hits your real cash flow.
7. Sort the pots. Down payment, closing costs, and reserves are separate gates. A program may accept borrowed money for one and refuse it for another.
The last point catches people. A loan officer in one BiggerPockets thread separates down-payment use from reserve use, and says the reserve use is the real problem.
Lenders across the network differ on borrowed funds. Some accept line proceeds toward the down payment. Others want a portion in your own unborrowed cash. A few ask for the funds to season before they count. Those are program choices, not federal rules.
Where the Stack Gets Tested: A Worked Example
Say you own a rental worth about the same as the next property you want to buy. The first mortgage on it is 40% of its value.
A 70% CLTV ceiling leaves room for a line of up to 30% of the value. The lender’s own valuation sets that figure, and your file still has to clear underwriting.
Now price the purchase side. On a DSCR purchase, most files land at 75% to 80% LTV, so you need 20% to 25% down. Select programs reach 85% LTV at roughly a 700 score. Closing costs come on top.
- At 25% down, a 30% line covers the down payment with about five points of value left for closing costs. Nothing remains for reserves.
- If the existing first mortgage were 50% of value, room shrinks to 20%. That is short of a 25% down payment, so you would need your own cash or a lower-down program. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Modeled assumption: the new property clears roughly 1.2x on its own payment. That looks comfortable. But the line payment is outside that ratio, and the line was drawn at least 75% at closing. Interest starts on day one.
Stress it. If rent slips 10%, coverage falls to roughly 1.08x. The loan still reads fine on paper. Your personal cash flow now carries the first mortgage on the old rental, the new mortgage, and the line, all from rent and income that just got thinner.
An investor on BiggerPockets makes the same point plainly: when the down payment is borrowed, the line is indirectly debt on the new property. You are close to fully financed.
Clearing 1.00 is not the same as positive cash flow. The DSCR test compares rent to PITIA only. It ignores repairs, vacancy, management, utilities, and capital expenses.
Which Property Should Secure the Line?
Put the line on the rental, and a default puts the rental at risk. Put it on your own home, and the home is the collateral. Yahoo Finance says it directly: if you cannot repay a line on your primary residence, you could lose that residence.
| Factor | Line on a rental | Line on your primary home |
|---|---|---|
| Asset at risk | The rental | Your home |
| Network ceiling | 70% CLTV | Up to 90% CLTV, only at 720+ |
| Minimum credit | 700 | Program floor of 600 |
| Maximum line | $500,000 | $750,000 |
| Draw structure | 5-year draw, 25-year repayment | Two structures available |
The 90% figure exists only at a 720-or-better credit profile, and it applies only to primary residences and second homes. A line above $500,000 requires at least a 700 credit profile (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal.
The rental-secured route keeps the risk on investment property rather than your residence. It costs you leverage, since 70% CLTV is the cap. Many investors would rather take less money than put their own roof behind a purchase.
Where Does the General Rule Break?
The general rule: the cash arrives, and the purchase lender decides whether it counts. These edge cases are where files go sideways.
- A fully borrowed down payment. Some programs want part of the down payment in unborrowed cash. Others accept it with documented source. Ask which kind you are dealing with before you draw.
- Seasoning. A lender may want the money to sit in your account for a period. One BiggerPockets poster reports a lender asking for two months, though that is one lender’s practice.
- Reserves. Reserves on a DSCR purchase commonly run around six months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Loans above $1,500,000 typically step up to about nine months. Borrowed reserves are usually the hardest sell.
- Prepayment penalty on the new loan. A step-down prepayment schedule makes a quick refinance expensive, which is how many investors plan to retire the line. One BiggerPockets contributor flags this as a risk of borrowing the down payment.
- LLC title. On Lendmire’s network, an LLC cannot hold title on the line’s collateral. Only the individual borrower or a revocable living trust can. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance is the better fit, subject to program terms.
- Exposure limits. A borrower is limited to three lines. A borrower owning more than 15 financed properties is not eligible.
- Property type. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not.
- Listing status. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
- A primary-residence purchase. If “another home” is the one you will live in, it is a different file. That lender reviews your file on personal income and debts, so the line payment counts against you there. A rental-secured line plus an owner-occupied purchase calls for a conversation with the lender before you draw.
What About the Line’s Own Risks?
The line’s pricing floats. The CFPB explains that you can generally borrow up to your limit during the draw period. After it ends, you enter repayment, payments are often much higher, and in some cases the whole balance comes due. Its HELOC brochure adds that these lines typically carry variable pricing.
On Lendmire’s investment lines, the draw period is interest-only for five years, then the balance amortizes over 25. The payment can jump when repayment begins. A line that looked easy at year two can look different at year six.
One BiggerPockets contributor calls a line suitable for a quick acquisition only if you can pay it off within a year or two. That is an opinion, not a rule. It is a useful test, though. If your exit plan is vague, the line probably does not fit.
The usual exit is a refinance of the new property once it has seasoned and the value supports it. That depends on appraisal results, seasoning rules, and how the market moves. Nobody can promise it.
When Does It Make Sense, and When Should You Skip It?
It makes sense when the new property has a clear path to covering both loans, when you hold meaningful reserves outside the line, and when you can name the exit.
Skip it when the numbers work only at full occupancy, when the line would eat your reserves, or when you cannot afford the first mortgage on the old rental, the new mortgage, and the line payment together.
The alternative is a DSCR cash-out refinance on the old rental. Cash-out refinances top out around 75% LTV across most of the network on standard rentals, with about six months of seasoning as the common expectation. You swap one loan for a larger one, so there is no second lien and no floating line. The tradeoff is a new first mortgage on the rental you already own. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Then comes the purchase side. A DSCR purchase loan underwrites the rent against the payment, so it suits a pure rental buy. Across the network:
- Leverage: Most files sit at 75% to 80% LTV.
- 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 or better unlocks the strongest 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.
A bigger down payment lowers the payment and can lift coverage. It does not erase credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. The complete DSCR loans guide walks through how those tests fit together.
Frequently Asked Questions
Can I draw the full line right away?
At least 75% of the line is drawn at closing on the network’s programs, so a large share of it starts costing you interest immediately. Size the line close to what you need, since unused cash still carries a payment.
Will the purchase lender count the line payment in the DSCR?
On a DSCR purchase, the ratio compares the new property’s rent to its own PITIA. The line payment generally sits outside it. That does not make the payment disappear. It still hits your cash flow, and some programs look at your broader obligations.
Does the line work if my rental sits in an LLC?
Not on this network. Title must be held by the individual borrower or a revocable living trust. A property in an LLC needs a vesting change first, or a DSCR cash-out refinance fits better, subject to program terms.
Can I use the line for reserves too?
Treat reserves as a harder case than down payment. Lenders vary on whether borrowed money counts there at all. Commonly they want about six months of PITIA in your own funds, though that can differ by lender, leverage, and loan size.
What if I want to buy my own home instead of a rental?
That purchase is underwritten on your personal income and debts, so the line payment counts against you. A rental-secured line adds a payment to that file even though the rental brings in income. Ask the purchase lender how it treats both before drawing.
