The Quick Read: It depends on the equity in a rental you already own: a DSCR HELOC on that rental typically allows combined leverage up to 70% of its value as a second lien, minus the first mortgage, on lines from $50,000 to $500,000, subject to underwriting and a rent test on the full line. The rent from the house you are buying does not set the amount. The line mostly funds the down payment on that purchase.
- The formula: property value × the combined loan-to-value cap, minus the balance on the first mortgage.
- Second lien: up to 70% combined leverage at a 720 credit score or better, through select programs.
- First lien (rental with no mortgage): up to 75% loan-to-value at 740 or better, and 70% from 700 to 739, on lines to $500,000.
- The rent test: the rental’s rent must cover a stress payment on the entire line at 1.10x or better.
- Draws: at least 80% of the line is drawn at closing, so size the line to the cash you need. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
What Is a DSCR HELOC, Really?
A DSCR HELOC is a revolving line of credit secured by a rental you keep. It is qualified on that rental’s rent, not on your personal income. Across the wholesale network Lendmire works with, the structure is one of two things. It is a standalone second lien behind the first mortgage you keep. Or it is a standalone first lien on a rental that has no mortgage.
The label confuses people, so here is what it is not. It is not a loan on the house you are buying. It is never a third lien, and it is never a line on your own home or a second home.
Your LLC can stay on title, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs an acknowledgment and the security instrument.
The qualifying work is done by the rent. The program asks for no traditional personal-income documentation, W-2s, pay stubs or personal debt-to-income calculation. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. For the full picture of how this family of loans fits together, see the complete DSCR loans guide.
How Much Can You Borrow? The Sizing Math
Your line equals value times the combined cap, minus every lien already on the property. That is the whole equity side of the answer.
Take the second-lien cap of 70% at a 720 score. “Combined” means the first mortgage balance plus the new line, divided by the property’s value. The cap covers all the debt together, not just the new line. You can only borrow what is left after the first mortgage.
Here is how that plays out with three different first-mortgage balances, expressed as a share of value:
| First mortgage (% of value) | Room at 70% combined | Read |
|---|---|---|
| 30% | 40% of value | Strong equity, large line possible |
| 50% | 20% of value | Workable on a higher-value rental |
| 65% | 5% of value | Usually below the $50,000 minimum |
That last row matters. Programs set a minimum line, and this one starts at $50,000. Five percent of value falls short of $50,000 on any rental worth less than $1,000,000. Positive math can still fail the minimum.
The ceiling is also hard. A second-lien line runs to $500,000, and the program never goes above 70% combined on a second lien.
The value in the formula is the lender’s valuation, not your estimate or your purchase price from years ago. A rental that has appreciated adds room. A rental whose valuation comes in light shrinks it.
First Lien or Second Lien: Which Ceiling Applies?
Your existing mortgage decides the lien position. If you keep a first mortgage, you can only take a second lien. A first lien exists only on a rental with no mortgage.
| Position | Credit score | Max leverage | Line size |
|---|---|---|---|
| Second lien | 720+ | 70% combined | $50,000–$500,000 |
| First lien | 740+ | 75% loan-to-value | To $500,000 |
| First lien | 700–739 | 70% loan-to-value | To $500,000 |
| First lien, larger line | 720+ | 65% loan-to-value | Above $500,000, to $1,000,000 |
These are ceilings, subject to underwriting, not offers. A borrower with a mortgage who scores between 700 and 719 has no second-lien tier. The obstacle there is the lien position, not a missing first-lien product. The first-lien floor is 700.
A first-lien line above $500,000 drops to the 65% ceiling. Bigger is not better here. Asking for a larger line can lower your leverage, so check whether the extra dollars are worth the lower cap.
Other eligibility points sit alongside the numbers:
- Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- Credit history matters. The program looks for no 30-day mortgage late in the last 12 months. It also looks for 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- No reserves are required.
- Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
Why the Rent Test Can Shrink Your Line
The equity cap is one ceiling. The rent is the second, and you get the lower of the two, unless three months of rent receipts support a lease above market.
The program requires a minimum DSCR (debt service coverage ratio) of 1.10x. That is gross monthly rent divided by the qualifying payment. The qualifying payment is a stress payment: a fully amortizing payment of principal and interest on the entire credit limit, calculated at 2 percentage points above the starting 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.
The detail most borrowers miss is that the test runs on the whole line, not on what you plan to draw. A line sized to every dollar of equity carries the biggest stress payment. A smaller line can pass when the maximum-equity line fails.
Picture a rental with deep equity but modest rent. The cap says you could ask for a large line. The rent test says the rent only supports a smaller one.
Rent used for lender review follows one rule. Rent is the lesser of the appraisal’s market rent (Form 1007) 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.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in the coverage calculation. The lender’s own calculation governs, and the arithmetic here is only illustrative.
How Do the Draw Rules Change How Much You Should Ask For?
Ask for the line you will use, because most of it is drawn on day one. 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.
The draw period runs 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period follows, with a 30-year maturity. The rate is variable.
Two practical lessons follow:
1. A big line “just in case” starts costing you interest at closing. It also raises the stress payment in the rent test.
2. When the draw period ends, the payment steps up as principal begins to amortize.
The CFPB booklet on home equity lines describes the standard sizing method. The lender takes a percentage of appraised value and subtracts what is already owed. That matches the formula above. The booklet is written around a borrower’s own home, so use it for the sizing logic, not for investor program terms.
The same guidance is plain about risk. The CFPB explains that falling behind on a home equity line can cost you the property securing it. For you, that property is a rental. A variable-rate balance on one rental can strain the rest of your portfolio, so treat the line as bridge capital with a plan to refinance or repay.
Does One Line Cover the Whole Next Purchase?
The line usually funds the down payment, not the whole purchase. You still need a loan or cash for the rest of the new house. Think of two separate approvals:
- Approval one: the line on rental A, which reads the rent, the equity, your credit and the valuation on rental A.
- Approval two: the purchase financing on rental B, which reads rental B’s numbers and its own down-payment rules.
Your sizing exercise therefore starts at the target. Work out the down-payment percentage the purchase lender wants. Apply it to the purchase price. Then check whether the line on rental A can supply that amount, plus your closing costs and any rehab budget.
- Each line attaches to one property. Equity does not pool across your rentals.
- Down-payment funds that come from a line are borrowed funds. The purchase lender sets its own rules on them, so ask before you draw.
- Purchase lenders commonly ask to see the line’s terms and the draw records, with funds traced into your account.
- The line’s payment is not part of rental B’s coverage ratio, because the line is secured by rental A. Whether the purchase lender counts it elsewhere in your file depends on that lender’s guidelines.
If you plan to refinance out of the line later through a DSCR cash-out refinance, check any prepayment terms on the loan you will be replacing.
What Are the Timing Rules?
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 shapes your sequence. A rental you just bought cannot carry a line right away. Plan your next purchase so the equity you need sits in a property that already meets both clocks. The line also needs to be in place before you make an offer you could not otherwise fund. Because it is never closed with a purchase, you set up the line first and then contract on the next house.
When the Number Comes Out Smaller Than You Expected
Thin equity is the obvious reason. Several other factors can lower the number or take a property out entirely.
Valuation. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better plus 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. If the automated value lands low, the room in your formula drops with it.
Market flags. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
Property type. Eligible property includes single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres. The leverage tiers above apply to every property type. These are outside the program:
- Rural-designated property
- Row homes
- Condotels
- Commercial or agricultural property
- Leaseholds and land trusts
- Age-restricted communities and hobby farms
- Modular and log homes
- Land contracts and mixed-use property
- A property listed for sale in the prior 2 months
- A property with a solar lien
Hazard insurance must cover both liens, with flood coverage where required. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Title. A full title policy applies on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
What Does This Compare To?
The right tool depends on whether you want to keep your first mortgage in place and whether you qualify on rent or on personal income.
| Option | What it touches | Reviewed on |
|---|---|---|
| DSCR HELOC | Adds a lien, keeps first mortgage | Rent |
| DSCR cash-out refinance | Replaces the first mortgage | Rent |
| Investment HELOC, personal income | Adds a lien | Personal income |
| Bank statement HELOC | Adds a lien | Bank deposits |
The other programs follow their own rules, which vary by lender. A cash-out refinance resets the whole loan and creates a lump sum. A line leaves the first mortgage alone and lets you draw in stages after closing. A HELOC on your own home is a different, owner-occupied product, and this line is never offered on an owner-occupied home.

Frequently Asked Questions
Can the line be on the house I am buying?
No. The line is a standalone lien on a rental you already own. After the seasoning clocks run, the new house could carry its own line.
What is the largest line I can get?
It depends on lien position and credit. A second lien runs to $500,000 at up to 70% combined leverage with a 720 score. A first lien on an unmortgaged rental can reach $1,000,000, but leverage drops to 65% loan-to-value above $500,000. Every figure is a ceiling subject to underwriting.
How long do I have to own a rental before it can carry a 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).
Is the interest on the line deductible?
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.
