The Quick Read: It depends on your equity and the rent, not on the stocks: a DSCR HELOC is sized at up to 70% combined loan-to-value on a second lien, on lines from $50,000 up to $500,000, subject to underwriting, but the program is built for business-purpose use, so a stock purchase is not generally something to count on. The size of the line comes from equity, credit tier and rent coverage. What you do with the money is a separate question, and it gets settled in the lender’s use-of-proceeds terms before you sign.
- The line size is a formula: property value times the leverage cap, minus every lien already on the property.
- A second lien behind your first mortgage tops out at 70% combined loan-to-value (CLTV) at a 720 credit score or better, subject to underwriting.
- The rent has to cover a stress payment on the entire line, so a bigger line needs more rent.
- At least 80% of the line is drawn at closing, so interest starts on most of the money right away.
- A DSCR HELOC is a business-purpose product, so ask for the use-of-proceeds terms in writing before you plan a brokerage deposit.
How Is the Maximum Line Calculated?
The maximum is the property’s value times the leverage cap, minus what is already recorded against it. The stock plan does not change that arithmetic. Across the wholesale network where Lendmire places these files, the structure is the same: the value comes from the valuation, the cap comes from the lien position and your credit tier, and the program’s dollar limits trim the result.
Start with the lien position. A DSCR HELOC is a standalone second lien behind a first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never closed with a purchase, and it is never a third lien.
Second lien (a first mortgage stays in place). CLTV means the first mortgage balance plus the new line, divided by value. The cap applies at a 720 credit score or better, on lines up to $500,000. Below 720 there is no second-lien option on this program, subject to underwriting. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
First lien (no mortgage on the rental). The cap depends on the tier and the line size:
- 740 or better: up to 75% loan-to-value (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: up to 65% LTV at 720 or better. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The first-lien floor is a 700 score. A borrower who keeps a first mortgage can only take the second-lien version.
Here is how the room shrinks on a second lien at the 70% cap:
| First mortgage as % of value | Room left under a 70% CLTV cap |
|---|---|
| 40% | 30% of value |
| 55% | 15% of value |
| 65% | 5% of value |
| 70% or more | None |
Those are illustrative percentages, and the lender’s own calculation governs. Two program limits can cut the result further. The smallest line is $50,000, so thin equity may produce no line at all. Some properties also carry a lower ceiling: a declining-market flag takes 5 points off, and Philadelphia lines sit 10 points lower.
Why the Rent Test Can Make the Line Smaller
The rent has to clear a coverage test, and that test can cap the line below your equity ceiling. This program qualifies 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.
The minimum DSCR is 1.10x. That is gross monthly rent divided by a qualifying payment. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit, figured at the start rate plus 2 percentage points. Taxes and insurance are not part of it. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The test runs on the full limit, not on what you plan to draw. A $500,000 line is tested as if all $500,000 were outstanding on a stress payment. Rent that supports a smaller line may not support the big one.
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. On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation, because that treatment is not published as a standard formula.
Can the Money Go Into Stocks?
Not as a safe assumption. A DSCR HELOC is a business-purpose loan, and the proceeds are expected to serve the rental business: the next acquisition, a renovation, or reserves for the portfolio. Buying a personal securities portfolio with the line sits outside that intent. Personal use of the proceeds can put the loan’s business-purpose status at risk.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The CFPB’s commentary on the business-purpose exemption says the creditor decides in each case whether the transaction is primarily for an exempt purpose. The CFPB’s exam procedures add that a checked business-purpose box alone may not be enough evidence. In practice the lender wants a signed business-purpose declaration, and a use-of-funds letter helps when the money is earmarked.
The investor’s job is to ask before applying, not after closing:
1. Does this program accept securities as a stated use of proceeds?
2. What does the business-purpose declaration say, and what happens if the money goes elsewhere?
3. Will the lender confirm the answers in writing?
If the answer to the first question is no, the stock plan needs a different source of cash.
What Happens to the Cash Flow Once the Line Is Drawn?
You pay interest on a large balance from 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 structure has two phases. You get a 5-year interest-only draw period on the drawn balance. Then a 25-year fully amortizing repayment period follows, with a 30-year maturity. The rate is variable, and the rate and pricing terms come with the lender’s disclosures.
A line draw does not change the rental’s DSCR, since that ratio compares the property’s rent with its own payment. A drawn balance can still show up on your credit report. That may matter for the next loan, subject to each lender’s guidelines.
The break-even logic is plain. Your portfolio has to earn more than the line costs after interest, every year, including the years the market falls. Borrowing against a rental to hold stocks stacks a variable-rate loan on top of market risk. HelocPedia’s list of risks names variable rates and the chance of a frozen line when home values fall.
Picture the bad year. Stocks drop, the variable rate rises, and a tenant leaves, all at once. The debt stays due, the rental income dips, and the portfolio you bought is worth less. A home-secured line has no brokerage margin call, but that is small comfort when the collateral is your rental.
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.
Which Tool Fits Which Goal?
The right tool depends on what the money is for. Here is how the common options compare in structure.
| Factor | DSCR HELOC | DSCR cash-out refinance | Loan from a brokerage against a portfolio | Bank HELOC on personal income |
|---|---|---|---|---|
| Reviewed on | Rental’s coverage ratio | Rental’s coverage ratio | Securities pledged | Your income and debts |
| First mortgage | Stays in place | Replaced | Not involved | Stays in place |
| Collateral | The rental | The rental | The portfolio | The property |
| Business-purpose limits | Yes | Yes | No | Depends on the product |
| Fit | Equity for rental goals | Large equity pull, reset the first lien | Buying more securities | Personal-income borrowers |
Those columns describe each product’s own rules, not this program’s. A DSCR cash-out refinance replaces the first mortgage, so it only makes sense when the existing loan is worth giving up. The business-purpose rules apply to its proceeds too.
Using the cash-out proceeds to buy another property keeps the money inside the real estate business, and the next property can add rent instead of market exposure.
Who Is Constrained or Ineligible?
Several property and borrower types fall outside this lane. Most of the surprises are in the property list, so check it before spending time on the numbers.
- Title. Vesting in your LLC is allowed on investment property. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
- Property type. Eligible: single-family, planned unit developments, townhomes, two-to-four units, warrantable and non-warrantable condominiums, and lots to 10 acres. Not eligible: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, and mixed-use. Also excluded are a property listed for sale in the prior 2 months and a property with a solar lien.
- Borrower. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not.
- Credit and exposure. No 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. A borrower may hold at most 5 loans or $2,500,000 with the program.
- 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).
- Valuation. Lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
- Reserves. None are required, and no cash to close is required.
If you already hold a first mortgage, read its terms for any limit on additional liens. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Every figure above is a ceiling or floor, not an offer, and each file is underwritten individually.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment, which shows whether the rent covers the debt.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Second lien: a loan recorded behind the first mortgage, paid second if the property is ever sold to settle debts.
Business-purpose loan: credit used mainly for a rental or other investment business, not for personal or household needs.
Frequently Asked Questions
What is the most I can borrow on a DSCR HELOC?
The ceiling is $500,000 on a second lien, and a first-lien line can run to $1,000,000 on a rental with no mortgage. Your actual limit is the lower of the leverage cap, the coverage test on the full line, and the valuation, subject to underwriting. For a first-lien line above $500,000, the cap is 65% LTV at a 720 credit score or better.
Does the rent have to cover the amount I draw or the whole line?
The whole line. The qualifying payment is figured on the entire credit limit at a stress level, then rent is divided by it, with a 1.10x minimum. That is why a smaller line can clear when a larger one on the same rental does not. At least 80% of the line (and never less than $50,000) is drawn at closing.
How long must I own the rental before applying?
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). Seasoning is measured from recorded dates, not from when you started shopping.
Can my LLC hold the property?
Yes, on investment property, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs an acknowledgment and the security instrument.
Will a drawn balance hurt my next loan?
It can. A drawn balance may appear on your credit report, and it does not change the rental’s own coverage ratio. Whether it matters on a later file depends on that lender’s guidelines.
