The Quick Read: It depends on the equity in the rental that secures the line, because the amount is a formula, not a fixed number: the property’s value times the maximum leverage for your credit tier, minus every lien already recorded, with lines running from $50,000 to a $500,000 ceiling on a second lien, subject to underwriting. The line sits on a rental you already own. It never sits on the third property, and it is never closed together with the purchase.
- Second lien (behind your first mortgage): combined loan-to-value (CLTV) up to 70% at a 720 credit score or better, on lines up to $500,000, through select programs.
- First lien (rental with no mortgage): loan-to-value (LTV) up to 75% at 740 or better, 70% from 700 to 739, and 65% on lines above $500,000 (lines run to $1,000,000).
- Coverage test: rent must reach 1.10x a stress payment on the entire credit limit, so a bigger line demands more rent.
- Draw rule: at least 80% of the line is drawn at closing, so size the line to the cash you actually need. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
How Is the Maximum Line Calculated?
The maximum line is the smaller of two ceilings: the equity ceiling and the program cap. The equity ceiling is property value times the allowed leverage, minus all existing liens. The cap is $500,000 on a second lien and $1,000,000 on a first lien. The rent test can also bind before either one does, and that comes up in a later section.
Work it in four steps.
1. Start with the value. The lender sets it through an automated valuation or an appraisal, not through your estimate.
2. Apply the leverage tier. Use the combined figure on a second lien (first mortgage balance plus the new line, divided by value). Use the plain LTV figure on a first lien.
3. Subtract what is already recorded. On a second lien, that means the first mortgage balance.
4. Check the floors and the cap. The remaining room has to reach the $50,000 minimum line, and it cannot exceed the cap for the lien position.
Here is a worked example in percentages. Say a rental has a first mortgage at 50% of its value, and the borrower scores 720 or better. The second-lien ceiling of 70% CLTV leaves room for a line of about 20% of value. Move the first mortgage up to 65% of value and the room drops to about 5%, which is usually too thin to reach the minimum line. Whether the $500,000 cap or the equity ceiling binds first depends on the property’s value and the existing liens, so run both numbers on your own file.
A declining-market flag on the property lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower. These are network guidelines, and every file is underwritten individually.
What Do the Leverage Tiers Allow?
The tiers differ by lien position, and credit score moves you between them. A borrower who keeps a first mortgage can only take a second lien. A first lien exists only on a rental with no mortgage.
| Lien position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | up to $500,000 |
| First lien | 700 to 739 | 70% LTV | up to $500,000 |
| First lien | 720 or better | 65% LTV | above $500,000, to $1,000,000 |
The 65% tier applies to larger lines, so a borrower at 700 to 719 should expect the first-lien floor of 700 to apply to the smaller lines only. There is no second-lien tier below 720. A borrower at 700 to 719 who owes money on the first mortgage cannot take a second-lien line through this program. These figures are ceilings, not offers, and they apply to non-owner-occupied one-to-four-unit rentals only. A primary-residence HELOC is a different, owner-occupied product with its own rules. This line is never written on your own home or a second home.
Which Rental Should Secure the Line?
Equity does not pool across properties. If you own two rentals, each one is tested alone on value, liens, rent and seasoning.
Picture an investor with two rentals. The first is a free-and-clear duplex. The second is a single-family house bought recently with a high-leverage first mortgage. The duplex can carry a first-lien line at up to 75% LTV with a 740 score. The single-family house probably has no room, and it may fail the six-month rule anyway. Using the duplex is the cleaner path. Adding a first-lien line to a free-and-clear rental also puts a lien on a property that had none, and that is a real tradeoff to weigh. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The collateral is also the risk. The CFPB’s HELOC booklet warns that missing payments can cost you the property that secures the line. If the line sits on a rental, that rental is exposed even though the money went into a different purchase.
Vesting in your LLC is allowed on this program for investment property, subject to program eligibility. The LLC members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Why Can the Rent Test Cap the Line Before Equity Does?
The rent test is run on the entire credit limit, not on what you draw. Qualification is primarily on property-level rental income covering the payment, subject to lender guidelines. The minimum is 1.10x, which means gross monthly rent divided by a stress payment. That payment is a fully amortizing payment on the whole limit at the start rate plus 2 percentage points.
That has three practical effects.
- A larger line means a larger stress payment, so the same rent supports a smaller line than the equity alone would allow.
- Taxes and insurance are not part of the qualifying payment. It is principal and interest on the full line.
- On a second lien, the lender’s coverage calculation governs. Confirm on the file how the lender treats the first-mortgage payment.
Rent used for lender review has one rule. 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 in place is required. A two-to-four-unit property may have at most one vacant unit. No traditional personal-income documentation, W-2s or personal income calculation are part of the test.
What Does the File Need Before the Line Opens?
The file needs a valuation, a title product, clean credit history and seasoning on the collateral rental. Each has a hard edge, and each is a place where a file stalls.
Valuation. Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
Title. A first lien and any second lien above $400,000 take a full title policy. Smaller second liens use an owner-and-encumbrance report. Hazard insurance covers both liens, and flood coverage is needed where required.
Credit. The floor is 720 on a second lien and 700 on a first lien. The lender’s own credit report sets the tier. The file needs no 30-day mortgage late in the last 12 months, and 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required.
Seasoning. 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).
Borrowers. U.S. citizens, permanent residents and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers cannot.
Property. Eligible types include single-family, PUD, townhome, two-to-four-unit, warrantable and non-warrantable condominiums, and lots up to 10 acres. Several types are outside this program:
- rural-designated property, row homes and condotels;
- commercial or agricultural property, and mixed-use;
- leaseholds, land trusts and age-restricted communities;
- hobby farms, modular and log homes, and land contracts;
- a property listed for sale in the prior 2 months, or one with a solar lien.
Each borrower can carry at most 5 loans or $2,500,000 with the program. Each line counts toward that exposure as the portfolio grows.
How Does the Third Purchase Actually Fit?
The line funds the down payment, and a separate loan buys the property. The sequence matters more than the numbers, because the line has to exist before you go under contract.
1. Pick the collateral rental. Test its value, liens, rent, lease and six-month clocks first.
2. Open the line. The line closes on the rental you already own, never together with the purchase.
3. Draw. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. Later draws are at least $5,000 each.
4. Sign the purchase. The third property gets its own DSCR purchase loan, underwritten on that property’s rent. The borrowed down payment needs a clear paper trail from the line to the closing table.
5. Repay or refinance. The draw period is 5 years interest-only on the drawn balance. Then a 25-year fully amortizing repayment period runs to a 30-year maturity. The rate is variable.
For the mechanics behind the purchase loan, see the complete DSCR loans guide.
The 80% draw rule changes how to size the line. You cannot open a large line and leave most of it unused. If the down payment and closing costs need a certain amount, take a line close to that amount. A bigger line raises the stress payment in the rent test.
What Should the Cash-Flow Check Look Like?
Run two checks: one on the new rental and one on your total monthly obligations. The line’s payment is interest-only on the drawn balance during the draw period. It steps up when repayment starts. The CFPB’s HELOC explainer notes that payments can jump sharply at that point, and some plans require the full balance back at once.
Picture an investor whose third rental covers its own purchase loan at a comfortable 1.2x. That ratio ignores the line. The line payment comes out of the investor’s own cash flow, so the real question is whether the two collateral rentals and the new property carry both obligations through a vacancy. A Yahoo Finance report on using a HELOC for a down payment frames the strategy as best for borrowers with healthy reserves and a plan to refinance or pay off the line within 12 to 24 months. This program requires no reserves, but that does not mean you should carry none.
Where This Doesn’t Work
The line does not fit in these situations:
- The rental was bought or refinanced in the last 6 months, or you have not held title for 6 months.
- The first mortgage already sits near the ceiling. A recent purchase made at high leverage often leaves no room under 70% CLTV.
- The rent is thin against a stress payment on the full limit. The coverage test fails before the equity does.
- The collateral is an owner-occupied home, a second home or any ineligible property type.
- The property is in Tennessee or another state the program does not serve, or the borrower is a foreign national or ITIN borrower.
- You would need only a small amount. The $50,000 minimum line and the 80% closing draw make small needs a poor fit.
The property’s state is the first gate, and Tennessee is the one licensed state where the program is not offered.
White Coat Investor notes that HELOCs on investment property are harder to find than HELOCs on a primary home, which is why many investors end up comparing structures rather than shopping one bank.
How Does It Compare With Other Ways to Pull Equity?
The line leaves your first mortgage in place and adds a second lien beside it. Other tools replace the first mortgage or qualify on personal income instead of rent.
| Option | What it does to the first mortgage | How it qualifies |
|---|---|---|
| DSCR HELOC (this program) | Leaves it in place (second lien) | Rent coverage at 1.10x on a stress payment |
| DSCR cash-out refinance | Replaces it with a new loan | Rent coverage, per that program’s rules |
| Bank statement HELOC | Leaves it in place | Personal bank deposits, per that program’s rules |
The right choice often turns on whether the existing first mortgage is worth keeping.
Key Terms Defined
Combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by the property’s value.
Lien position: whether the new loan sits behind your first mortgage (second lien) or is the only loan on the property (first lien).
Draw period: the stretch when you can borrow from the line and pay interest only on the drawn balance. On this program it lasts 5 years.
Stress payment: the qualifying payment on the entire credit limit at the start rate plus 2 percentage points. It is used only to test coverage.
Seasoning: the time a rental must be owned or sit unrefinanced before the line is available.
Frequently Asked Questions
Can a DSCR HELOC be placed on the third property I’m buying?
No. The line is never closed together with a purchase, so the third property cannot secure its own down payment. The line goes on a rental you already own, and the purchase closes separately with its own loan underwritten on that property’s rent.
What is the maximum I can borrow on a second-lien line?
The ceiling is 70% combined loan-to-value at a 720 score or better, with lines from $50,000 up to $500,000. The usable amount is value times 70%, minus your first mortgage balance, and then the rent test can lower it. All figures are subject to underwriting.
Does a higher credit score raise the leverage cap?
On a second lien, no. 720 or better is the only tier, and it tops out at 70% CLTV. On a first lien, a higher score does matter: 740 or better reaches 75% LTV, while 700 to 739 stops at 70%. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
How soon after buying a rental can I open a line on it?
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 clocks apply to the collateral rental, not to the property you plan to buy.
Can my LLC hold the property that secures the line?
Yes, for investment property, subject to program eligibility. The members sign as guarantors, and any title holder who is not a borrower signs the security instrument and a non-borrowing owner acknowledgment. The borrowers on the line need not match the borrowers on the first mortgage.
