The Quick Read: It depends on equity first: on a second lien behind your first mortgage, the line can reach 70% combined loan-to-value at a 720 credit score or better, up to $500,000, but the purchase lender decides how much of that draw counts as your down payment. Two separate approvals apply, one for the line and one for the purchase. The line is qualified on the rental’s income, not yours, subject to lender guidelines and underwriting. Treat the ceiling as a cap and size the draw to what the purchase needs.
- The line ceiling is the rental’s value times the combined cap, minus the mortgage you already owe.
- Lines run from $50,000 to $500,000 on a second lien, and at least 80% of the line is drawn at closing.
- The new property’s coverage ratio generally counts only its own monthly payment, not the line’s payment.
- Down payment, closing costs and reserves are three separate buckets, and the line mainly serves the first.
- Your real cash flow still has to carry both payments.
Key Terms Defined
DSCR HELOC: a revolving line of credit on a rental you keep, qualified on the rent instead of your personal income.
Combined loan-to-value (CLTV): your first mortgage balance plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): monthly rent divided by the monthly payment the rent must cover.
Seasoning: the waiting period a lender wants after you buy or refinance a property.
Reserves: cash left in verified accounts after closing, which a purchase lender may require.
Standalone second lien: a line that sits behind your first mortgage and closes on its own, not alongside a purchase.
What Is a DSCR HELOC, and How Is It Different From a Home Equity Line?
A DSCR HELOC is a home equity line on a one-to-four-unit rental that you do not live in. It is written as a standalone second lien behind the first mortgage you keep. It can also be a standalone first lien on a rental with no mortgage. It is never a line on your own home, and it never closes together with a purchase.
The rent qualifies the line. The lender does not calculate your income, so no traditional personal-income documentation, W-2s or pay stubs come into it, subject to lender guidelines. Your LLC can stay on title, depending on program guidelines. The members sign as guarantors.
That is the main difference from the home equity line a bank offers on a primary residence. That product is owner-occupied and judged on your income. NerdWallet notes that rental-property lines come from a smaller pool of lenders and allow less borrowing than lines on a primary home. A wholesale network widens that pool, and Lendmire arranges these lines as a broker through select programs. It does not lend. The line is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.

How Is the Maximum Line Calculated?
The maximum line equals the property’s value times the combined cap, minus what you already owe on it. Then the line size limits apply on top. Run it one property at a time. Equity on one rental never pools with equity on another.
On a second lien, the cap is 70% CLTV at a 720 score or better, and lines run from $50,000 to $500,000. Below 720 there is no second-lien tier. A rental with liens at 55% of its value leaves room worth 15% of value. A rental with liens at 72% of its value leaves nothing.
A rental with no mortgage can take a first lien instead. The leverage depends on the score and the line size:
| Lien and line size | Credit score | Maximum leverage |
|---|---|---|
| Second lien, to $500,000 | 720 or better | 70% CLTV |
| First lien, to $500,000 | 740 or better | 75% LTV |
| First lien, to $500,000 | 700 to 739 | 70% LTV |
| First lien, above $500,000 (to $1,000,000) | 720 or better | 65% LTV |
All figures are ceilings, subject to underwriting. A declining-market flag on the property can lower the ceiling by 5 points. A higher score does not buy extra leverage on a second lien beyond the 720 tier.
General consumer guidance from the CFPB’s guide to using home equity says lenders typically want you to keep 10% to 20% of home value as equity. A 70% CLTV ceiling on a second lien leaves at least 30% of value untouched, so this program sits inside that cushion.
What Does the Line Itself Have to Pass?
The line must pass a coverage test of at least 1.10x. The test divides gross monthly rent by a stress payment on the entire credit limit, not only the drawn part. That payment is principal and interest only. Taxes and insurance are not part of it.
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.
Here is the catch for sizing. A bigger line raises the stress payment, which lowers the coverage number. A rental with modest rent can fail on a large line and pass on a smaller one. Whether the first-mortgage payment joins that calculation on a second lien is not something to assume. Confirm on the file how the lender treats it.
The file also includes:
- A credit report with no 30-day mortgage late in the last 12 months.
- At least 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- For lines to $400,000, an automated valuation with a property inspection report, or a full interior appraisal.
- For larger lines, a full interior appraisal.
The program requires no reserves and no cash to close on the line.
Will the Purchase Lender Accept Borrowed Funds?
That question belongs to the second approval, and the answer varies by purchase program. Some purchase lenders accept a documented line draw as down payment. Others cap the borrowed share or want some unborrowed funds. They may treat the down payment, closing costs and reserves differently.
Two separate parties decide two separate things:
| Approval | Who decides | What they check |
|---|---|---|
| The line | The HELOC lender | Rent coverage, credit, equity, valuation |
| The purchase | The DSCR purchase lender | Borrowed-funds treatment, new property’s coverage, reserves |
The practical rule is to ask the purchase lender before you draw. Ask whether line proceeds are accepted, in what share, and what source-of-funds paperwork it wants. Expect statements that show the draw landing in your account (or your LLC’s account) and then moving to closing.
Does the HELOC Payment Hit the New Property’s DSCR?
Generally, no. The new property’s coverage ratio is its monthly rent divided by its own full monthly payment: principal, interest, taxes, insurance and any association dues. The line’s payment usually sits outside that ratio, subject to the purchase lender’s guidelines.
That is why many investors assume the line is free. It is not. Your bank account carries both payments. The ratio is a lender test. Your cash flow is the real one.
Two features of the line matter here. The draw period is 5 years interest-only on the drawn balance, so early payments are lighter. Then a 25-year fully amortizing repayment period begins, which raises the payment. The rate is variable, so the payment can move as well. Plan for the payment after the draw period, not only the one at closing.
How Do Down Payment, Closing Costs and Reserves Differ?
They are three buckets, and a line draw may be treated differently in each. Keep them apart in your planning:
| Bucket | What it covers | Line draw usually counts? |
|---|---|---|
| Down payment | Your share of the price | Often, if the purchase lender accepts borrowed funds |
| Closing costs | Lender, title and third-party charges | Depends on the purchase program |
| Reserves | Cash left after closing | Lenders generally want verified assets, not borrowed equity |
The line never waives the purchase loan’s own rules. The new loan still wants its own down payment, its own reserve requirement where one applies, and its own credit standards. The line mainly funds the first bucket. Size reserves from your own verified accounts. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What Do Three Real Scenarios Look Like?
Each scenario below is illustrative. The lender’s own calculation governs.
| Scenario | Rental backing the line | New purchase | Read |
|---|---|---|---|
| Small draw | Liens near 55% of value, strong rent | Clears roughly 1.25x | Pass on both gates |
| Full draw | Liens low, uses all available room | Clears roughly 1.15x | Pass only if the purchase lender accepts the full borrowed share |
| Thin rent | Rent barely covers the line’s stress test | Barely above 1.0x | Fails the 1.10x minimum, so it does not clear the first gate |
In the small-draw case, the line uses part of the 15% of value that remained. The new purchase covers its payment with room, and the line payment is light because the balance is small. This is the cleanest file.
In the full-draw case, the investor borrows every available dollar. The line may still pass its own 1.10x test. The risk moves to the purchase side. If the purchase lender caps the borrowed share, part of the down payment must come from your own funds, and the draw falls short.
In the thin-rent case, the problem is cumulative. A rental that barely covers the line may fall short of the line’s 1.10x minimum, and then it does not clear the first gate. A new property that barely covers its payment may also fall short of the purchase lender’s test. Even if both tests were met, adding the line payment on top could turn monthly cash flow negative. When you borrow almost the whole down payment, you are financing close to the entire purchase. That leaves little room if rents soften or the variable payment rises.
How Much Should You Borrow?
Borrow what the purchase needs, not what the ceiling allows. Work it in reverse:
1. Find the down payment percentage the purchase program wants, and convert it to a share of the price.
2. Add closing costs. Set reserves aside from your own funds.
3. Check how much of that the purchase lender will accept as borrowed money.
4. Compare the result to the room on the rental: value times the cap, minus existing liens.
5. Test the line’s 1.10x coverage at that size.
Remember that at least 80% of the line is drawn at closing, and later draws are at least $5,000 each. So the line cannot be much larger than the draw you need. Opening a big line “just in case” means you pay interest on most of it from day one. Later draws exist, so a line can fund more than one purchase over time. Each later purchase starts with the same two gates and leaves less equity behind.
The sequence matters too:
- Open the line on the rental you already own, before you go under contract.
- Ask the purchase lender how it treats borrowed funds.
- Draw, and keep the statements showing where the money went.
- Let the funds sit in the account if the purchase lender asks for seasoned funds.
- Then go under contract on the new property.
The line is written on a rental you keep, so it risks that rental. A line on your own home is a different, owner-occupied product, and this program does not offer it.
If the line is the main source of your down payment, stress-test your cash flow with both payments and a higher variable payment. The CFPB’s page on how a HELOC works also notes that a lender can reduce or freeze a line if the home’s value drops significantly. Do not plan around a line that you might not be able to draw later. 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 Rentals and Borrowers Are Outside the Program?
Several property types and borrower profiles fall outside it. These are the main limits:
- Rural-designated property, condotels, row homes and leaseholds are not eligible.
- Commercial or agricultural property, land trusts, age-restricted communities and hobby farms are not eligible.
- A property listed for sale in the prior 2 months, or with a solar lien, is not eligible.
- Single-family, planned unit developments, townhomes, two-to-four units and condominiums are eligible property types.
- 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 is capped at 5 loans or $2,500,000 per borrower with the program.
- Foreign nationals and ITIN borrowers are not eligible. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are.
The borrowers on the line do not have to be the borrowers on the first mortgage. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
HELOC or Cash-Out Refinance?
A line fits a modest cash need and the flexibility to draw again. A DSCR cash-out refinance replaces your first mortgage, so it fits larger amounts or a permanent reset. It may also fit a borrower whose score falls below the line’s floors. Cash-out has its own seasoning, leverage and score rules, and they differ from this program’s.
The trade-off is plain. A line leaves your existing first mortgage untouched and adds a second lien. A refinance resets the whole structure. If your first mortgage is one you want to keep, the line is the more direct route to equity.
Frequently Asked Questions
Can the line be my entire down payment?
Sometimes, but the purchase lender decides. Some accept a documented draw as the whole down payment. Others cap the borrowed share or require unborrowed funds. Ask before you draw, and keep reserves and closing costs in mind, because those may have separate rules.
Does the line payment lower the new property’s DSCR?
Generally, no. The line’s payment sits outside the new property’s ratio, subject to the purchase lender’s guidelines. It still reduces your real monthly cash flow, so test both payments together.
Can I draw against the property I am buying?
No. The line is a standalone second lien on a rental you already own, and it never closes together with a purchase. After the new property is yours and the seasoning clocks have run, it could back a line of its own.
How long must I own the rental before opening 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). A rental that meets both can be reviewed.
Can my LLC hold the rental that backs the line?
Yes, subject to lender program eligibility. The LLC can stay on title for an investment property. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
