The Quick Read: Usually up to 70% combined loan-to-value on a second-lien line, with lines from $50,000 to $500,000 at a 720 credit score or better, but the draw you can actually use is the smaller of that ceiling and what the purchase lender will count as down payment. The line is sized on the equity in the rental that secures it, and the rent on that rental has to cover the qualifying test, subject to lender guidelines.
- A second-lien line behind a mortgage you keep reaches 70% CLTV at 720 or better, to $500,000.
- A first-lien line on a rental with no mortgage reaches 75% LTV at 740 or better and 70% at 700 to 739, with lines to $500,000.
- A first-lien line above $500,000, up to $1,000,000, carries a 65% LTV ceiling.
- At least 80% of the line is drawn at closing, so size the line to the cash you need.
- The purchase lender decides how much borrowed money counts as down payment, so get its position in writing first. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
What Sets the Draw Limit?
Two limits apply, and the smaller one wins. The first is the line itself: value times the combined-leverage ceiling, minus what is owed on the first mortgage. The second is the purchase lender’s rule on borrowed funds.
The federal consumer-finance regulator’s HELOC booklet describes the same basic formula: take a percentage of appraised value, subtract the mortgage balance, and the remainder is the potential line. Lenders also weigh the borrower’s ability to repay.
On a DSCR HELOC, the percentage and the repayment test come from the program. Across the wholesale network Lendmire works with, the second-lien ceiling is 70% CLTV at 720 or better. Below 720 there is no second-lien tier. Those are ceilings, not offers, and every file is underwritten individually.
How Do You Size the Line?
Take a rental valued at $500,000 with a first mortgage you plan to keep. At 70% CLTV, the first mortgage plus the new line cannot exceed 70% of value. Whatever room sits between your current balance and that ceiling is the most the line can be, and the line cannot pass $500,000 or fall under $50,000.
That arithmetic is illustrative. The lender’s own calculation governs, and a declining-market flag lowers the ceiling by 5 points.
You do not need the maximum. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. A line sized to your actual down payment and closing costs avoids carrying a large balance you did not need. Borrow for the target, not the ceiling.
How Does the Rent Qualify the Line?
The rental qualifies the line, not your paycheck. Minimum DSCR is 1.10x, which is gross monthly rent divided by a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit, tested at a stress rate above the start rate. Taxes and insurance are not part of it. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease must be in place, and a two-to-four-unit property may have at most one vacant unit.
Because the test runs on the whole line, a bigger limit lowers coverage even if you draw less. On a second lien, confirm on the file how the lender treats the first-mortgage payment. The qualification runs primarily on property-level rental income covering the payment, with no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
What Does the Purchase Lender Decide?
The purchase lender decides what counts. The HELOC only supplies cash. The DSCR purchase loan is a separate file with its own leverage tier, credit floor and reserve rules. Across the network, programs differ on three points:
| Question | What programs vary on |
|---|---|
| Borrowed down payment | Some accept a fully borrowed amount; others cap the borrowed share |
| Seasoning of funds | Some want the cash sitting in your account first |
| Reserves | Some programs exclude borrowed money from reserves |
A fully borrowed down payment is not zero down. It means financing close to 100% of the price across two loans, and the new rental must carry both payments in real life. Investor accounts on BiggerPockets make the same point about rent covering the HELOC payment as well as the loan.
Ask the purchase lender three questions before you draw: what share can be borrowed, whether the funds must season, and whether borrowed funds count toward reserves. Get the answers in writing. The DSCR coverage ratio on the purchase itself compares that property’s rent with that property’s own payment, and a larger down payment lowers the new loan and can lift the number, whether the cash is borrowed or not. The complete DSCR loans guide covers the purchase side in detail.
Which Property Can Secure the Line?
A rental you already own, held for at least six months. The line is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never written on your own home or a second home, and it is never closed together with a purchase.
Seasoning is two six-month clocks: a rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
Title can sit in an LLC, subject to program terms, with the members signing as guarantors. Rural property, condotels, row homes, leaseholds and land trusts are outside this lane, and a property listed for sale in the prior 2 months is not eligible.
| Collateral | Leverage ceiling | Credit floor | Line range |
|---|---|---|---|
| Second lien | 70% CLTV | 720 | $50,000 to $500,000 |
| First lien, top tier | 75% LTV | 740 | to $500,000 |
| First lien, mid tier | 70% LTV | 700 to 739 | to $500,000 |
| First lien, larger line | 65% LTV | 720 | above $500,000 to $1,000,000 |
What Paper Trail Makes the Draw “Documented”?
Keep one clean line from the draw to the escrow. That means the HELOC statement showing the draw, the bank statement showing the deposit, and the transfer or wire to the title company. If the purchase lender allows the LLC to hold the funds, deposit them there from the start rather than moving them twice.
Valuation also shapes the file. Lines to $400,000 use an automated valuation with a property inspection report or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
The sequence matters more than speed. Open the line and take the draw before you go under contract. Lenders can freeze or reduce a line if value falls or credit weakens, and a frozen line cannot be drawn. The CFPB’s HELOC explainer confirms that you generally can spend up to the limit only during the draw period.
Key Terms Defined
Combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line, which on this program is 5 years interest-only on the drawn balance.
Repayment period: the stretch after the draw period, which here is a 25-year fully amortizing schedule inside a 30-year maturity.
Seasoning: how long a property or a pile of cash has to sit before a lender counts it.
Sourced funds: money you can trace to a documented origin, such as a specific draw.
Borrowed funds: cash that came from a loan, which some purchase lenders limit or exclude.
Should You Borrow the Full Amount? (The Carrying-Cost Test)
Not automatically. The ratio counts one payment, but you pay two. The new rental’s rent was never underwritten to cover the line’s payment, and the line carries a variable rate, so the payment can rise.
Run a simple test: rent, minus the purchase loan’s payment, minus the line’s payment. If that number is thin or negative, the structure is stretching. The same is true if the deal only works while the line’s payment stays low. BiggerPockets Rookie makes the stress-test point plainly: ask whether the deal survives if the line’s cost jumps.
The honest tradeoff: a smaller draw means more of your own cash in the deal, and a fuller draw means thinner cash flow and a second lien on the property that secures the line. An investor with steady cash reserves elsewhere and a high-coverage purchase can reasonably draw more. An investor whose cash flow only works at maximum leverage is signaling that the deal needs a bigger down payment or a different property.
A DSCR HELOC is also not the only way to pull equity. Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance Draw as a Documented Rental Down Payment covers the other route, which replaces the first mortgage instead of sitting behind it.
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.
Where Do These Plans Break?
- Thin coverage on the line. The stress test runs on the entire limit, so an oversized line can fail at 1.10x even if you plan to draw little.
- Borrowing against the property you are buying. The line must sit on a seasoned rental you already own.
- Early contract timing. Going under contract before the draw is in your account leaves no paper trail.
- Reserves. Borrowed cash may satisfy the down payment but not the reserve test on the purchase.
- Exposure limits. The program allows at most 5 loans or $2,500,000 per borrower.
Frequently Asked Questions
Can HELOC money count as the down payment on a DSCR purchase?
Often yes, but the purchase lender decides. Some programs accept a fully borrowed down payment and others cap the borrowed share or want some unborrowed funds. Ask for the lender’s written position before you draw, and keep the documented trail from draw to escrow.
Does the HELOC payment lower the DSCR on the new rental?
Generally not. The purchase ratio compares that property’s rent with that property’s own payment. The line’s payment still reduces your real cash flow, so test the combined carry as well as the ratio.
How long must a rental be owned before it can secure the line?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). Both are measured on the rental that secures the line.
What is the most I can take on a second-lien line?
Up to 70% CLTV at a 720 credit score or better, with lines from $50,000 to $500,000, subject to underwriting. Because at least 80% of the line is drawn at closing, size the limit to the cash you need. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
