The Quick Read: It depends on three limits, and the tightest one wins: a single DSCR HELOC (a home equity line on a rental you already own) runs up to $500,000 on a second lien at 70% combined loan-to-value, the purchase lender must accept borrowed funds, and your own cash flow must carry the interest. Each limit is subject to underwriting.
- A second-lien line on a non-owner-occupied rental runs from $50,000 to $500,000, up to 70% CLTV at a 720 credit score or better, through select programs.
- A first-lien line (a rental with no mortgage) reaches 75% LTV at 740 or better, and lines above $500,000 drop to 65% LTV.
- The program caps each borrower at 5 loans or $2,500,000, so ten houses cannot be funded by ten separate lines.
- The rent on the source rental qualifies the line, but the purchase lender decides whether the cash counts as your down payment.
- Your bank account pays the line’s interest, so test the combined payments before you contract on any house. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Why Is There No Single “Maximum” for Ten Houses?
Three separate gates set the number. The equity in your source rental sets the first gate. The purchase lender’s view of borrowed money sets the second. Your own monthly cash flow sets the third. A ten-house package makes each gate tighter, because the cash need is ten times larger.
A DSCR HELOC is a revolving line secured by a rental you keep. 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. It is never closed together with a purchase, and it is never a line on your own home.
The rental itself qualifies the line. The lender looks at the rent, not at your tax returns, W-2s or personal income calculation, subject to lender guidelines. Vesting in your LLC is allowed through select programs, which helps if you hold your rentals in an entity.
Then the down payment on the package is a separate file. The ten-house loans have their own lender, their own rules and their own test. The line only feeds cash into that file.
How Big Can the Line Get?
The line size comes from one formula: property value times the leverage cap, minus what you owe on the first mortgage. A second-lien line is capped at 70% CLTV (combined loan-to-value, meaning the first mortgage plus the new line, divided by value) on a non-owner-occupied rental. That cap requires a 720 credit score or better, and lines run up to $500,000. Below 720 there is no second-lien option in this program. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Run it as percentages. Say your first mortgage is 45% of the rental’s value. A 70% CLTV cap leaves 25% of value for the line. If the first mortgage is 60% of value, only 10% of value is left. The same rental with no mortgage opens a much larger line, because the first-lien cap applies instead.
| Lien position | Credit score | Leverage cap | Line size |
|---|---|---|---|
| Second lien | 720+ | 70% CLTV | $50,000–$500,000 |
| First lien | 740+ | 75% LTV | Up to $500,000 |
| First lien | 700–739 | 70% LTV | Up to $500,000 |
| First lien, larger | 720+ | 65% LTV | Above $500,000 to $1,000,000 |
A first lien exists only on a rental with no mortgage. If you keep a first mortgage, you take a second lien, and the 720 floor applies. A declining-market flag on the property can lower the ceiling by 5 points. The figures above are ceilings and floors, never offers.
Valuation sets the other practical limit. Lines up 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.
NerdWallet’s explainer on investment-property HELOCs notes that this kind of line has a smaller pool of lenders and stricter requirements, and that more than one appraisal may be required. That matches what a broker sees across a wholesale network: the product is narrower than a standard home equity line, which is why the program rules matter.
The general sizing logic is not unique to rentals. The CFPB’s HELOC booklet explains that a lender sets a credit limit by taking a percentage of the appraised value and subtracting what you owe.
What Does the Rent Have to Prove?
The rental must show a debt coverage ratio of at least 1.10x. That ratio is gross monthly rent divided by the qualifying payment. The qualifying payment is a fully amortizing payment on the entire credit limit, not just the drawn amount, at a stress rate above the start rate. Taxes and insurance are not part of that payment.
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.
Whether the first-mortgage payment joins the qualifying payment on a second lien is something to confirm on the file. The lender’s own coverage calculation governs, and the arithmetic here is illustrative only.
The practical point: a larger line means a larger stress payment, so rent that clears 1.10x on a $250,000 line may fall short on a $500,000 line. Size the line to the rent, not just to the equity.
Why Can’t One Line Fund Ten Down Payments?
Because the program caps exposure at 5 loans or $2,500,000 per borrower, and each rental carries only one line. The most you could pull through this program is five lines, and only if five seasoned rentals each have the equity and the rent to support one.
Start with the cash need, then work backward. Add three items:
1. The down payment: package price times the down-payment percentage the purchase program sets.
2. Closing costs across all ten files.
3. Reserves, which many purchase programs want to see in unborrowed money.
That total is your target. Compare it with what your source rentals can supply under the formula above. Many investors find the gap is the reserves, not the down payment.
The line itself needs no reserves and no cash to close. The purchase loans are another matter, and they may ask for both.
One more structural point. A blanket loan is a single note secured by several properties and tested on a pooled coverage ratio. Ten separate loans each stand on their own. A blanket can simplify the paperwork, but the whole package becomes one file, and a lender reviewing borrowed funds may look harder at one large down payment. Release clauses, which let you sell one house without paying off the note, apply to blanket loans only. Ask which structure the purchase lender prefers before you size the line.
Will the Purchase Lender Accept Borrowed Funds?
Often yes, but it is the purchase lender’s call, not the HELOC lender’s. Across a wholesale network, programs differ. Some accept a HELOC as a down payment source with a paper trail. Some cap the borrowed share. Some require a minimum of your own cash. A few strict overlays want reserves untouched by borrowed money.
Bring these questions to the purchase lender before you draw:
- Does borrowed money count toward the down payment, closing costs, or both?
- Is there a cap on the borrowed share, or a minimum of my own cash?
- Can borrowed funds count toward reserves?
- Does a blanket package treat borrowed funds differently from ten separate loans?
- How does the lender view the new second lien on the source rental?
Expect to document the line agreement, the draw statement and the deposit trail. The cash must sit in your account and be traceable before you contract on the first house. The line closes first, then you draw, then you buy.
Also check for a prepayment penalty on the new purchase loans. A penalty narrows your exit if you plan to sell or refinance a house early, and you will still be paying the line during that time.
Lendmire’s piece How to Use a Bank Statement HELOC as Down Payment on a Ten-House DSCR Package covers the other route, where personal deposits rather than rent qualify the line.
Which Rentals Can Carry the Line?
The source rental must clear seasoning and property 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). A house you just bought for the package cannot fund the next one right away.
Eligible property types include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Not eligible: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, modular and log homes, mixed-use, a property listed for sale in the prior 2 months, and a property with a solar lien. Philadelphia lines carry a ceiling 10 points lower.
Borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible on this program.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. A rental outside those states cannot carry the line, and the state also affects where your package properties sit in the wider plan.
Credit history matters too. The program looks for no 30-day mortgage late in the last 12 months and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
Can You Carry the Payments?
Borrowed down payment means two debts against one rent stream. The rent from each new house covers that house’s loan on the DSCR test. Your own pocket covers the line’s interest, including during a vacancy or a rehab.
At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. You start paying interest on most of the line from the first day. The draw period is 5 years of interest-only payments on the drawn balance, followed by a 25-year repayment period and a 30-year maturity. The rate is variable, so the payment can move after you have already committed to ten purchases.
When the interest-only period ends, the payment steps up because principal begins to amortize. Model both phases. A package that works during the interest-only years can look different in repayment.
Run the test in this order:
1. Add the line’s payment to the payments on all ten new loans.
2. Compare that total with the combined rent, not the rent on one house.
3. Stress it with a vacancy on two or three houses at once.
4. Check what happens when the repayment phase starts.
If the answer relies on every house being full every month, the package is thin. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The CFPB’s consumer page on HELOCs states that a lender can freeze or reduce a line if the home’s value falls or your finances change. Read your line agreement for that language. A line secured by a rental puts that rental at risk if you fall behind, rather than your residence. A bank HELOC on your own home is a different, owner-occupied product, and this program is never offered on an owner-occupied home. Tax treatment varies; consult a qualified professional.
Think about this honestly: the strongest packages are usually the ones where the line covers only part of the cash need, and the investor funds the rest and the reserves from savings.
What If the Line Falls Short?
Work down this list in order, and stop when the cash need is covered:
- Shrink the first tranche. Buy four or five houses now and the rest after the rentals season and rents stabilize. Smaller packages need smaller lines.
- Add a second source rental. A second seasoned rental with equity can carry its own line, up to the 5-loan and $2,500,000 per-borrower limits.
- Use a cash-out refinance on a rental. This replaces the first mortgage rather than adding a second lien behind it. It may fit when the existing first mortgage is small.
- Bring in partner capital. A partner’s cash is not borrowed against your rentals, and it often keeps the purchase lender’s questions simpler.
- Reconsider the structure. A blanket package changes how the purchase lender views the down payment.
| Funding source | Lien on source rental | Qualified on |
|---|---|---|
| DSCR HELOC | Second or first lien | Rent coverage, 1.10x |
| Bank HELOC (personal income) | Usually individual title | Your income and DTI |
| DSCR cash-out refinance | Replaces first mortgage | Rent coverage, per program |
| Partner capital | None | Partnership terms |
Lendmire’s article How to Use a Rental HELOC as Down Payment on a Ten-House DSCR Package goes deeper on the single-house version of this decision.
The complete DSCR loans guide explains how the purchase loans themselves are structured, which matters here because the line is only half of the package.
Key Terms Defined
- DSCR (debt service coverage ratio): gross monthly rent divided by the property’s monthly payment, used to judge whether a rental pays for itself.
- CLTV (combined loan-to-value): the first mortgage plus the new line, divided by the property’s value.
- Second lien: a loan that sits behind the first mortgage, paid second if the property is sold or foreclosed.
- Blanket loan: one note secured by several properties, tested on their pooled income.
- Seasoning: the waiting period a lender requires after you buy or refinance a property before it will lend on it again.
- Draw period: the stretch when you can borrow from a line and pay only interest on what you drew; in this program it runs 5 years.
Frequently Asked Questions
What is the most I can borrow on one DSCR HELOC?
A second-lien line goes up to $500,000, capped at 70% CLTV on a non-owner-occupied rental with a 720 score or better. A first-lien line, on a rental with no mortgage, goes up to $1,000,000, but lines above $500,000 are capped at 65% LTV. The equity formula and the rent test usually set a lower number than those maximums, unless three months of rent receipts support a lease above market. Everything is subject to underwriting.
Does the line’s payment count against my DSCR on the new houses?
On most DSCR purchase files it does not, because that ratio tests each new property’s rent against its own payment. Your personal income is generally not the test. Your cash flow still absorbs the line’s interest, so it matters for how long you can carry the package through a vacancy.
How soon can I use a rental I just bought as the source 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). A rental still inside either window cannot carry the line.
Can I leave most of the line undrawn as a cash cushion?
No. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. Plan on paying interest on most of the line from the start. A line is also not reserves, and many purchase programs exclude borrowed money from reserves.
Can my LLC hold the rental that secures the line?
Vesting in an LLC is allowed through select programs, and the members sign as guarantors. Bank-style investment HELOCs usually need individual title, so a DSCR HELOC is a different product. The borrowers on the line need not be the borrowers on the first mortgage.
