The Quick Read: It depends on the rental’s equity, and the rent can shrink the number but never raise it: the line equals the property’s value times the maximum combined leverage, minus every lien already on it, then capped by the program’s dollar limit and the rent-coverage test. Your business’s size or revenue does not set the limit. Here is what to expect on a rental with a first mortgage, subject to underwriting.
- On a second lien, combined loan-to-value (CLTV) tops out at 70% at a 720 score or better, on lines up to $500,000.
- 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.
- Lines run from $50,000, and at least 80% of the line is drawn at closing.
- The rent has to cover a stress payment on the whole line at a 1.10x minimum.
- No reserves are required, and the owner’s personal income is never calculated.
What a DSCR HELOC Actually Is
A DSCR HELOC is a revolving line of credit secured by a rental you keep. It is written as a standalone second lien behind the first mortgage, or as a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, and it is never placed on your own home.
The rent qualifies the line. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, so there is no traditional personal-income documentation, W-2s, pay stubs or debt-to-income calculation. Vesting in your LLC is allowed on this investment-property line, subject to program terms, and the members sign as guarantors.
The term is loose across the market. Some lenders use it for a closed-end second mortgage or a cash-out refinance. Here it means a revolving line on a one-to-four-unit non-owner-occupied rental. Lendmire is a broker that places these files with a wholesale lender in its network, and the complete DSCR loans guide covers the wider family of rental programs.
How Is the Maximum Line Calculated?
The maximum line is the smaller of two numbers: the room your equity leaves under the leverage cap, and the line the rent can support. Start with the equity number, because that is the one most owners hit first.
Equity room works in three steps:
1. Set the value. 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. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
2. Apply the cap. Multiply value by the maximum combined leverage for your lien position and score.
3. Subtract what is already owed. On a second lien, the first mortgage balance comes out of the cap. The new line is whatever remains.
Combined leverage counts the first mortgage plus the full line limit, not just what you draw. A line sized right at the cap leaves no cushion. A declining-market flag can lower the ceiling by 5 points, so a valuation that lands softer than you expect changes the answer.
NerdWallet’s explainer on investment-property HELOCs notes that these lines are harder to get than primary-home lines and that not every lender offers them. That scarcity is why a broker with wholesale access matters.
The Leverage Tiers, Side by Side
| Lien position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien (keep first mortgage) | 720+ | 70% CLTV | $50,000-$500,000 |
| First lien (no mortgage) | 740+ | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700-739 | 70% LTV | Up to $500,000 |
| First lien (no mortgage) | 720+ | 65% LTV | Above $500,000 to $1,000,000 |
Those are ceilings, not offers, and all are subject to underwriting. A borrower who keeps a first mortgage can only take a second lien, which carries the 720 floor. A first lien exists only on a rental with no mortgage.
Here is a worked pass at a second-lien file, using modeled inputs rather than market data. Say a rental is valued at $400,000 and carries a first mortgage. At 70% CLTV, the combined ceiling is 70% of value. Every dollar of first mortgage balance comes off that top, and what remains is the maximum line. If the first mortgage already sits near 60% of value, only about 10 points of value are left for the new line. A lower-balance mortgage leaves far more room. Pencil your own balance against your own valuation before planning a budget.
Now the same property with no mortgage. At 75% LTV and a 740 score, the ceiling is 75% of value, and the whole thing is available as a first-lien line, up to the program’s dollar limit. That is why the same rental can support a much larger line once the mortgage is gone. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Does the Rent Limit the Line?
Yes, and this is the step investors skip. The program requires a minimum 1.10x DSCR, which is gross monthly rent divided by the qualifying payment. That payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, a stress payment. Taxes and insurance are not part of it.
Two features of that test surprise people:
- The whole line is tested, not the drawn amount. A $300,000 line is qualified as if all $300,000 were outstanding and amortizing.
- 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, and a two-to-four-unit property can have at most one vacant unit.
So an equity-rich rental with thin rent can hit the coverage wall before the leverage wall. If the number lands under 1.10x, the answer is a smaller line, a different property, or a different product. Whether the first-mortgage payment joins the qualifying payment on a second lien is something to confirm on the file, because the lender’s own coverage calculation governs.
Matching the Line to the Business’s Real Cash Need
Size the line to the business, not to the maximum. The structure is built so that 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 are at least $5,000 each.
That shapes the planning. If your business needs money in stages, such as inventory now and equipment in nine months, a large line funds mostly up front, and interest runs on that drawn balance during the 5-year interest-only draw period. A 25-year repayment period follows, with a 30-year maturity. The rate is variable.
Practical sizing questions to answer before applying:
- Can the business productively deploy 80% of the line immediately?
- If not, would a smaller line fit better, within the $50,000 minimum?
- What happens to the repayment period if the business is still young when amortization begins?
Cash that sits idle in a business account while interest runs is a cost with no return.
What Else Can Shrink the Number
Credit and property details trim a line even when equity looks generous.
- Credit. A 720 score is the floor on a second lien and 700 on a first lien. There should be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Property type. Single-family, PUD, townhome, two-to-four units and condominiums are eligible. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use and a property listed for sale in the prior two months are not.
- 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).
- Exposure. A borrower is limited to 5 loans or $2,500,000 with the program, which matters for owners with several lines.
- Borrower status. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What Does “Business Purpose” Mean Here?
Because the proceeds fund a business, the loan is a business-purpose investor loan, and it is reviewed differently from a standard owner-occupied mortgage. The purpose is documented at closing, and it has to be true in substance. The CFPB’s Truth in Lending exam chapter lists the exemption for credit extended primarily for a business purpose. Saying a loan is for business does not make it.
Lenders generally do not restrict what the money is spent on, and approval rests on equity, credit and rental coverage, not the strength of your business plan. NerdWallet’s business-lending page makes the same point and advises treating a home equity line as a last-resort option. A clean paper trail helps: move the draw into a separate business account and keep records of how it was spent.
Where Most Owners Misjudge the Risk
A rental line is personal exposure. Even if an LLC owns the business, the line is secured by your rental, and the members sign as guarantors on an LLC-held property. And a HELOC doesn’t build business credit, as Nav explains.
Few owners go this route. Bankrate cites a Federal Reserve Small Business Credit Survey finding that about 5% of owners rely on home equity for startup financing.
Stress-test two things before committing. First, a vacancy or rent drop puts the rental’s own income at risk while the line payment keeps running. Second, a variable rate can move the payment after the interest-only period ends. Because the whole line is qualified on a stress payment at the start, qualifying says the rent can carry it today, not that it will in every future year.
This is a genuine fork. A startup with no revenue history leans on the rental to carry both the line and the business’s early losses. An established business with steady cash flow can usually service its own debt, which makes the line a lower-risk bridge. If the business case only works when the rent carries everything, it is worth asking whether the business is ready for secured debt at all.
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 (debt service coverage ratio): gross monthly rent divided by the qualifying payment on the line.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by property value.
LTV (loan-to-value): the line divided by property value, used on a first lien with no other mortgage.
Draw period: the 5 years during which you pay interest only on the drawn balance.
Stress payment: a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only to qualify.
Business purpose: the stated and documented use of the funds for a business rather than personal or household use.
When a Different Product Fits Better
A DSCR HELOC is not always the right tool. Compare it against the alternatives, and note that other programs’ figures belong to those programs, not this one.
| Option | How it qualifies | Key tradeoff |
|---|---|---|
| DSCR HELOC | Rental income | Mostly drawn at closing |
| DSCR cash-out refinance | Rental income | Replaces the first mortgage |
| Personal-income HELOC | Owner’s income and DTI | Opens the personal file |
| SBA or business loan | Business financials | Slower documentation |
The case for a cash-out refinance is a first mortgage you would like to replace anyway. The case against it is giving up a low-rate first mortgage you want to keep; a second-lien line leaves it untouched. NerdWallet notes cash-out refinances on investment property are usually limited to 70% to 75% across the market.

Across a wholesale network, programs differ on valuation, lien position and entity title. The ranges here reflect select programs, and every file is underwritten individually.
Frequently Asked Questions
Can the business’s revenue increase how much I can borrow?
No. The line is sized by property value, combined leverage, existing liens and the rent-coverage test. The business’s age or revenue does not enter the formula, and the owner’s personal income is not calculated.
What is the most I can borrow on a rental that has a mortgage?
Up to $500,000 on a second lien, at 70% CLTV with a 720 score or better, subject to underwriting. The practical ceiling is usually lower, because the first mortgage balance and the 1.10x coverage test both reduce it.
Can I hold the rental in an LLC and still take the line?
Yes, on this investment-property line, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
How soon after buying a rental can I take 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).
Do I need an appraisal?
Lines up to $400,000 can use an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
