The Quick Read: It depends on which of three limits binds first: the combined loan-to-value ceiling minus what you already owe, the program’s dollar limit of $500,000 on a second lien, or the rent test run on a stressed payment for the entire line. The interest-only period changes what you pay while you draw. It does not raise the amount you can borrow.
- On a second lien behind your first mortgage, the combined loan-to-value (CLTV) ceiling is 70% at a 720 credit score or better, on lines from $50,000 to $500,000, subject to underwriting.
- On a rental with no mortgage, a first-lien line reaches 75% loan-to-value (LTV) at 740 or better and 70% from 700 to 739 on lines up to $500,000. Lines above $500,000, up to $1,000,000, carry a 65% ceiling.
- The rent must cover a stress payment on the whole line at a debt-service coverage ratio of 1.10x or better.
- You pay interest only on the drawn balance for 5 years, then principal and interest over a 25-year repayment period.
- At least 80% of the line is drawn at closing, so the line is not a stand-by cushion. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment. A result of 1.10x means rent is 110% of that payment.
DSCR HELOC: A revolving line of credit secured by a rental you own, qualified on the rental’s income instead of your personal income.
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value. On a first-lien line with no other mortgage, the same idea is simply LTV.
Draw period: The stretch when you can borrow from the line and pay interest only on what you have drawn.
Repayment period: The stretch after the draw period ends, when you can no longer borrow and the balance pays down over time.
Stress payment: A fully amortizing payment on the entire credit limit, figured at the start rate plus 2 percentage points. Lenders use it only to test the rent, not as the bill you receive.
Second lien: A loan that sits behind your first mortgage. The first lender is paid first if the property is ever sold or foreclosed.
The Three Limits That Set Your Line
The final line is the lowest of three numbers. Property value times the leverage ceiling, minus every lien already on the property, gives the equity room. The program’s dollar range sets the outer walls. The rent test then decides how much of that room the rental can carry.
Across the wholesale network, a DSCR HELOC is one of two shapes. It is a standalone second lien behind the first mortgage you keep. Or it is a standalone first lien on a rental with no mortgage. It is never a third lien. It is never closed together with a purchase. It is never a line on your own home or a second home. The rental has to be non-owner-occupied, one to four units.
Here is the equity-room math, written as percentages of value so it holds for any price. These are illustrative inputs, and the lender’s own calculation governs.
| Step | Example A | Example B |
|---|---|---|
| Value | 100% | 100% |
| CLTV ceiling (second lien) | 70% | 70% |
| First mortgage owed | 45% of value | 60% of value |
| Room for the new line | 25% of value | 10% of value |
In Example B, the room is only 10% of value. That works only if 10% of value reaches the $50,000 minimum line. On a modest rental it does not, and no line exists. On a higher-value rental, the same percentage may clear the minimum easily.
The dollar walls matter at the other end. A second-lien line tops out at $500,000, even if the equity room is larger. A first-lien line can run to $1,000,000. Going above $500,000 on a first lien costs leverage: the top tier drops from 75% to a 65% LTV ceiling, available at a 720 score or better. A borrower who wants a bigger line sometimes ends up with less usable equity than the tier below.
Why the Rent Test Often Binds First
The rent test is the limit that surprises borrowers who focus on equity alone. It uses a stress payment on the full credit limit, not on what you draw. The stress payment is principal and interest on the entire line, amortized fully, at the start rate plus 2 percentage points. Taxes and insurance are not part of it.
That design means the interest-only period gives you no extra room. You may pay interest only on the drawn balance for 5 years. But the test assumes the whole line amortizes from day one at a higher rate. A rental can look comfortable at a drawn-balance payment and still miss the test.
Run it as ratios. Say a rental covers an interest-only payment on the drawn balance at roughly 1.4x. Tested on the stress payment for the full line, the same rent might land near 1.05x. That falls short of the 1.10x minimum, so the line has to shrink until the stress payment fits. Treat those numbers as illustration only.
Because the stress payment scales with the line size, the rent sets a ceiling on the line. Higher rent supports a bigger line. Lower rent shrinks it, no matter how much equity exists.
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 can have at most one vacant unit. The appraiser’s market rent comes from Form 1007.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in the coverage calculation. The lender’s calculation governs, and the answer can shift the line size.
How the Interest-Only Period Really Works
You pay interest only on the drawn balance for 5 years, then the line moves into a 25-year repayment period. The maturity is 30 years in all. The rate is variable.
The CFPB’s explanation of home equity lines describes the general shape. A HELOC is an open-end line you can borrow against repeatedly during a draw period. After that period you can no longer borrow, and a repayment period begins. The CFPB’s HELOC booklet adds two points that matter here. On interest-only plans you pay nothing toward principal during the draw period. And because most lines carry a variable rate, the monthly payment can change even if you borrow nothing more.
Two things follow for an investor.
First, interest-only is not paydown. The balance on day 1,800 is the balance you drew, give or take later draws. Equity in the rental grows only through appreciation or your own principal payments elsewhere.
Second, the draw rules limit flexibility. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws must be at least $5,000 each. If you only want a small standby cushion, this is the wrong tool.
The payment step-up at the end of the draw period is the big planning point. In the repayment period, the full balance amortizes over 25 years. Principal is added to interest for the first time, and the variable rate can move the payment either way. Test the repayment-phase payment against your rents well before year five, not at year five.
What the Program Requires of the File
These requirements are typical of select programs in the network, subject to underwriting.
Credit. The minimum score is 720 on a second lien and 700 on a first lien. The score tier is the lender’s own report. A mortgage history with no 30-day late in the last 12 months is expected. At least 48 months must have passed since a bankruptcy, foreclosure, short sale, or deed in lieu. No reserves and no cash to close are required.
Income. The rental’s income qualifies the line. That means no traditional personal-income documentation, W-2s, pay stubs, or personal income calculation, subject to lender guidelines. The rent, the lease, the credit report, and the valuation are all documented.
Valuation. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report. A full interior appraisal is also accepted on those lines. Lines above $400,000 require a full interior appraisal on Form 1004, 1073, or 1025. Appraisal waivers are not accepted.
Borrowers and title. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. The property can sit in your LLC, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
Exposure. One borrower can hold at most 5 loans or $2,500,000 with the program.
Property. Single-family homes, PUDs, townhomes, two-to-four units, and warrantable and non-warrantable condominiums are eligible. So are lots up to 10 acres. Not eligible: rural-designated property, condotels, row homes, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use, commercial, and agricultural property. Also out are properties listed for sale in the prior 2 months and properties with a solar lien. A declining-market flag lowers the leverage ceiling by 5 points.
What Seasoning Rules Apply?
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). This catches the investor who buys a rental, rehabs it, and wants to pull equity out right away. Plan the timeline around both dates before you plan the line.
Which Limit Wins? A Quick Decision Guide
Use this as a checklist, working top to bottom.
1. Thin equity. If you owe a lot on the first mortgage, the CLTV ceiling binds first. The room may fall below the $50,000 minimum line, and then no line exists.
2. High equity, modest rent. The rent test binds first. The line shrinks until the stress payment fits at 1.10x.
3. High equity, strong rent, high value. The dollar limit binds. Second liens stop at $500,000. First liens above $500,000 drop to a 65% ceiling.
4. A weaker credit tier. A 700 to 719 score has no second-lien option. It can still work on a first lien, which exists only on a rental with no mortgage.
5. Valuation surprises. If the valuation comes in under your expected value, every percentage ceiling shrinks with it.
A smaller line than the maximum is often the smarter choice. A bigger line raises the stress payment, the closing draw, and the repayment-period payment all at once. Many investors size the line to a specific project and a known repayment plan instead of grabbing the ceiling.
How It Compares With a Cash-Out Refinance
A DSCR cash-out refinance replaces your first mortgage with one new loan and hands you equity as a lump sum. A DSCR HELOC leaves the first mortgage alone and adds a revolving line beside it. The tradeoff is structural.
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Funds | Line, mostly drawn at closing | One lump sum |
| Rate | Variable | Can be fixed |
| Payments early on | Interest only on drawn balance | Fully amortizing |
| Best fit | Keep a low first mortgage | Reset the whole loan |
If your first mortgage is one you want to keep, the line protects it. If you would rather consolidate into one loan, the cash-out route fits better. Different lenders also treat the first mortgage differently in the coverage math, so compare both options on the same property.
Risks and Exit Plans
The payment floats. Rents on a long-term rental tend to be steady, but a variable-rate payment is not. Stress your own numbers with a higher payment than today’s.
Repayment is a step up. When principal joins the payment at the end of the draw period, coverage can tighten. Know whether the rental can carry that payment, and decide early whether you will refinance, pay down, or sell.
Selling means paying off the line. The line is secured by the rental. Selling the property means paying the line off.
Rent shortfalls hurt twice. A vacancy can strain your cash flow and also your next refinance. If you have more than one vacant unit on a two-to-four-unit property, the line is not available at all.
Marketing numbers mislead. Home-equity advertising is built around primary-home borrowing. The NerdWallet HELOC explainer reports that most HELOC lenders cap combined loan-to-value at 85% on a primary residence. On an investment property in this program, the second-lien ceiling is 70% CLTV. NerdWallet’s investment-property explainer also notes that investors face a smaller pool of lenders and cannot borrow as much as against a primary home.
The honest read: the DSCR HELOC suits an investor who keeps a first mortgage worth keeping, has equity and a strong lease, and has a plan for the repayment period. For a different structure, Lendmire’s piece How Much Can You Borrow on a Bank Statement HELOC With a 10-Year Interest-Only Draw Period? covers a line qualified on personal bank deposits instead of rent. A broader overview lives in Lendmire’s complete DSCR loans guide.

Frequently Asked Questions
Does the interest-only period let me borrow more?
No. The ceiling comes from value, existing liens, the program’s dollar limits, and the rent test on a stress payment for the full line. Interest-only changes the payment you make while drawing. It does not enter the qualifying math in your favor.
What happens when the 5-year draw period ends?
You can no longer borrow. The balance then amortizes over a 25-year repayment period, so principal is added to interest. The payment usually rises, and the variable rate can move it further. Plan your refinance, paydown, or sale before that point.
Can I draw only a small amount at closing?
No. At least 80% of the line (and never less than $50,000) is drawn at closing. On the smallest lines, that means the whole line. Later draws can be as small as $5,000.
How soon can I use it after buying or refinancing the rental?
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 have to be met before a file moves forward.
Can my LLC hold the property, and do I need a first mortgage?
Yes to the LLC, subject to program terms, on investment property only. The line is either a second lien behind a first mortgage you keep, or a first lien on a rental with no mortgage. Members sign as guarantors, and the borrowers on the line need not be the borrowers on the first mortgage.
