The Quick Read: On a rental you keep a mortgage on, the line is the property’s value times 70%, minus the first mortgage balance, and it tops out at $500,000. The credit score, the rent test and the property all have to clear first, subject to underwriting.
- Second lien: up to 70% combined loan-to-value (CLTV) at a 720 score or better, on lines of $50,000 to $500,000.
- First lien (no mortgage on the rental): up to 75% loan-to-value (LTV) at 740 or better, 70% from 700 to 739, with lines to $1,000,000.
- The rent test: a minimum 1.10x coverage on a stress payment over the whole line.
- Where it works: 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Every figure here is a ceiling, not an offer. Final amounts depend on the valuation, the credit report and the lender’s own calculation.
What Is a DSCR HELOC?
A DSCR HELOC is a revolving line of credit on a rental you own. The rent qualifies it, not your paycheck. It is written as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage.
That is different from a DSCR cash-out refinance, which replaces your first mortgage. It is also different from a bank line underwritten on your personal income. The term gets used loosely, so ask which structure a quote actually describes.
The line is never closed together with a purchase. It is never a third lien. It is never placed on your own home or a second home. If you want the full picture of how rent-based loans work, the complete DSCR loans guide covers it.
An LLC can stay on title (investment property only), subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment.
How Is the Maximum Line Calculated?
The maximum line equals the property’s value times the leverage cap, minus every lien already recorded. The CFPB’s HELOC booklet describes the same basic method: take a percentage of appraised value, then subtract the mortgage balance.
Here is how that plays out on a second lien. Take a rental valued at $450,000 and a 70% CLTV cap. Total lien room is $315,000 (this is plain arithmetic on an illustrative value, not a market statistic). Your existing first mortgage uses part of that room, and the rest is the most the line can be.
The table shows how the same property behaves as the first mortgage changes. Percentages are of value.
| First mortgage as % of value | Room under 70% CLTV | What it means |
|---|---|---|
| 30% | 40% of value | Roomy; the $500,000 cap may bind first |
| 50% | 20% of value | Workable; the line minimum matters |
| 65% | 5% of value | Too thin for a $50,000 line |
| 70% or more | None | No second-lien room |
Two limits can stop you. The first is equity: the percentage cap. The second is the program’s line cap of $500,000 on a second lien. On a high-value, lightly mortgaged rental, the line cap binds before equity does. On a heavily mortgaged rental, equity binds long before the cap.
Lines also start at $50,000. If your math leaves less room than that, a second-lien line is not a fit. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. On the smallest lines, that means most of the line is drawn at closing.
What About a Rental With No Mortgage?
A rental with no mortgage can take a first-lien line, and the ceilings are higher. Through select programs, the first-lien tiers run like this, subject to underwriting:
- 740 or better: up to 75% LTV on lines to $500,000.
- 700 to 739: up to 70% LTV on lines to $500,000.
- Lines above $500,000, up to $1,000,000: 65% LTV at 720 or better. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Note the drop. Anyone sizing a first-lien line above $500,000 should plan around 65%, not 75%. On a free-and-clear rental worth $600,000, for example, the large-line ceiling is 65% LTV, which is why the biggest lines suit high-value properties. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
A first lien exists only on a rental with no mortgage. If you keep a first mortgage, a second lien is your path, and the second-lien score floor is 720. The first-lien floor is 700.
How Does the Rent Test Work?
The rent test sets whether you qualify, not how much equity you can reach. A rental with strong rent does not unlock more equity. But a rental with weak rent can fail the test even with plenty of equity.
Minimum coverage is 1.10x. That is gross monthly rent divided by the qualifying payment. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit at a stress rate. It is not your actual payment, and taxes and insurance are not part of it. Because the stress payment covers the full limit, a bigger line makes the test harder.
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.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs, and illustrative math should be treated that way.
The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s or personal income calculation. Credit, value and equity are still reviewed. The rent, lease, credit report and valuation are all documented.
How Do Big Banks and Brokers Differ on Line Size?
A big bank offers its own product menu, and many large retail lenders do not put a rental-property line on it. NerdWallet reports that fewer lenders offer a HELOC on an investment property and that you generally cannot borrow as much as you could against a primary home.
A broker works the other way around. Lendmire is a mortgage broker that works with a network of wholesale DSCR HELOC lenders. It matches the property, rent, equity and credit profile to the program that fits. It does not lend or approve. The lenders decide.
| Factor | Big bank or large retail lender | Broker-placed wholesale program |
|---|---|---|
| What gets tested | Often personal income and debt ratios | The rental’s rent against a stress payment |
| Access | One lender’s menu | Several programs compared |
| Typical obstacle | Rental line may not be offered | Equity, score, property type |
| LLC title | Often needs a title change | Allowed on this program, subject to program terms |
The tradeoff is real. A bank where you already hold deposits may price a relationship line differently, and a bank line qualified on personal income can suit a W-2 borrower with one rental and little debt. A rent-based line fits better if you hold rentals in an LLC, are self-employed, or carry debt that would sink a debt-to-income test.
Which Kind of “No” Did You Get?
A bank’s “no” comes in different types, and only some can be fixed. Sort yours first.
- Product not offered. The bank does not write lines on rentals. A broker can look elsewhere. Some banks decline anything called a “HELOC” on a rental but offer a “line of credit” (an anecdote on a BiggerPockets thread), so naming matters.
- Personal income fails. Debt-to-income is too high. A rent-qualified line moves that test to the property.
- Title fails. The rental is in an LLC. The program above allows LLC vesting, subject to program terms.
- Equity fails. The combined balance is already near the cap. A different lender will not fix the math. A cash-out refinance, which replaces the first lien, may be the better route.
- Score fails. A second lien needs 720. A 700 to 719 borrower with a first mortgage cannot use this line, though a first-lien line on a rental with no mortgage starts at 700.
What Disqualifies a Property or Borrower?
Check these before you spend time on numbers.
- Credit history: no 30-day mortgage late in the last 12 months. 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Borrower status: US citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- Exposure: at most 5 loans or $2,500,000 per borrower with the program.
- Property types that do not fit: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, mixed-use, a property listed for sale in the prior 2 months, and a property with a solar lien.
- Eligible types: single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres.
A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
Seasoning has 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).
How Is the Property Valued?
The valuation sets the number everything else multiplies. 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. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
NerdWallet also notes that investment properties can require more than one appraisal. A low valuation shrinks the line dollar for dollar at your leverage cap, so a property that looked comfortable on an online estimate can come in tighter.
Hazard insurance covers both liens, and flood coverage applies where required. No reserves and no cash to close are required.
What Do Draw and Repayment Terms Mean for Your Plan?
The line works in two phases. For 5 years you pay interest only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable.
The CFPB describes a HELOC as an open-end line you can borrow against repeatedly during a draw period. Because the payment moves with the balance and the rate, the cost of a fully drawn line can rise at repayment. Plan for that step-up before you draw.
Size it to the use. It suits a down payment on the next rental, rehab, or consolidating higher-cost debt on the property.
If the funds buy another rental, that purchase needs its own loan, and the line payment still comes out of your pocket whether or not the new property covers its own debt. 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.
Key Terms Defined
- DSCR: gross monthly rent divided by the qualifying payment; this program’s minimum is 1.10x.

- Standalone second lien: a line recorded behind your first mortgage without changing that mortgage.
A Short Checklist for Comparing a Bank Quote With a Broker Quote
Ask each of them the same things.
1. Is the line a first or second lien, and is it written on a rental?
2. What is the combined loan-to-value cap, and does it change with my score?
3. Does the test use my personal income or the rent?
4. Can the property stay in my LLC?
5. What is the maximum line, and the minimum draw at closing?
6. How is the property valued, and could a second appraisal be required?
7. What is the draw period, repayment period and maturity?
The rate and the pricing terms come with the lender’s disclosures, so compare those in writing.
Frequently Asked Questions
What is the most I can borrow on a rental with a mortgage?
Up to $500,000 on a second lien, and only if value times 70% minus your first mortgage leaves that much room. The score must be 720 or better. The lender’s valuation and underwriting decide the final number.
Can I get a line on a rental I own free and clear?
Yes, through select programs, as a standalone first lien. The ceiling is 75% LTV at 740 or better and 70% from 700 to 739, on lines to $500,000. Lines above $500,000 run to $1,000,000 at a 65% LTV ceiling at 720 or better. All of it is subject to underwriting. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
How soon after buying a rental can I take 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). Both must be satisfied.
Does a higher credit score mean more leverage?
Only up to a point. A second lien has a single tier at 720 or better, with a 70% CLTV ceiling. A first lien steps from 70% to 75% LTV at 740, so a higher score matters there. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Can a rental held in an LLC qualify?
Yes, on this program an LLC can hold the investment property, with members signing as guarantors, subject to program terms. A bank line qualified on personal income often cannot be held by an LLC, so check this first if your rentals sit in an entity.
