The Quick Read: A home equity line of credit (HELOC) on your current rental supplies the cash for your down payment and closing costs, while a separate DSCR purchase loan buys the new property. Two different lenders review two different files. One reads you and the equity in the collateral property. The other reads the new property’s rent and decides whether borrowed money is acceptable as your down payment.
- The line must be open on a property you already own, before you go under contract on the next one.
- On the network Lendmire places files with, an investment-property line tops out at 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a $500,000 maximum line.
- The DSCR purchase loan sets its own leverage, credit, reserve, and borrowed-funds rules, and your HELOC does not override them.
- Clearing 1.00 on the coverage ratio does not mean the deal puts cash in your pocket, because the line payment lands on top.
- Many rentals sit in an LLC, and the investment line cannot be written to an LLC, so the title question often decides which path you take.
Key Terms Defined
HELOC: A revolving line of credit secured by a property you own. You borrow against it as needed during a draw period, then repay.
CLTV (combined loan-to-value): All loans secured by the property, plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s full monthly housing payment. The lender uses it to judge whether the rent carries the loan.
PITIA: Principal, interest, taxes, insurance, and any HOA dues. It is the payment figure on the bottom of a DSCR calculation.
DTI (debt-to-income ratio): Your monthly debts divided by your monthly income. HELOC lenders check it. DSCR purchase lenders generally do not run it.
Seasoning: The time a lender wants funds or ownership to sit before they count. Down-payment money often has a sourcing and seasoning check.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
How Does the Two-Loan Structure Work?
The HELOC never buys anything. It turns trapped equity into cash in your bank account. Then a second, unrelated loan closes the purchase. Each lender looks at a different thing, and approval on one says nothing about the other.
| Item | HELOC lender | DSCR purchase lender |
|---|---|---|
| What it reads | You and the collateral property | The new property’s rent |
| Key tests | Credit, CLTV, DTI, title | Coverage ratio, credit, reserves, leverage tier |
| Collateral | Your current property | The property you are buying |
| Decides | Line size | Whether borrowed funds count |
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 loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The lender typically orders an appraisal that includes a rent schedule (Form 1007) or, on small multifamily, an operating income statement (Form 1025).
A conventional lender would add the HELOC payment to your debt-to-income ratio. A DSCR file generally does not run that test. Your line payment stays outside the ratio, but it still comes out of your real cash. That gap is where most of the risk in this plan lives. For the full picture of how these loans work, see Lendmire’s complete DSCR loans guide.
Which Property Should Secure the Line?
You have two collateral options: the rental you already own, or your primary home. The rental route is narrower, and it puts the rental at risk if the line goes bad. The primary-home route is easier to find and reaches higher leverage, but it puts your house on the line.
| Item | Line on current rental | Line on primary home |
|---|---|---|
| Availability | Narrow, a niche product | Broader market |
| Network CLTV ceiling | 70% on an investment property | Up to 90% on a primary residence, only at 720+ credit |
| Maximum line | $500,000 total | Larger lines possible |
| Title | Individual or revocable trust | Individual or revocable trust |
| What you risk | The rental | Your home |
The 70% figure holds at both the 700 and 720 credit tiers on an investment property, so a higher score buys eligibility rather than extra leverage. A 700 score is a hard floor with no tier beneath it. Lines run 5 years of interest-only draw followed by 25 years of repayment. Pricing floats during both periods and never converts to fixed. At least 75% of the line is drawn at closing.
Availability is the first hurdle. One investor on BiggerPockets described calling about a dozen local banks and finding only one that offered a rental HELOC. That is a single account, not a statistic. It matches what brokers see: many depository institutions simply do not sell the product, regardless of how strong your file is.
The HELOC product also reaches a narrower footprint than Lendmire’s DSCR loans. HELOCs are available in Lendmire’s 16 full-service states, while DSCR investor loans cover 40 states plus Washington, D.C. If you want to see the primary-home route in detail, Lendmire covers how to use a bank statement HELOC on your primary home to buy a rental.
What Is the Step-by-Step Sequence?
The order matters more than any single number. Run these steps in sequence.
1. Check your equity room. Subtract your existing liens from the lender’s CLTV cap applied to value. If nothing is left, stop here.
2. Ask the DSCR lender about borrowed funds first. Learn whether line proceeds are accepted as down payment, in what share, and for what sourcing. Ask before you draw a dollar.
3. Open the line before you need it. The collateral must already be yours. You cannot open a line on the rental you are about to buy.
4. Fund the line before you go under contract. An undrawn line is permission to borrow, not money. Lenders can freeze or reduce lines, so never sign a contract that depends on one you have not drawn.
5. Draw only what the deal needs. That means down payment, closing costs, and a rehab buffer. Idle drawn money still costs you interest.
6. Park the draw in a dedicated account. The purchase lender will want to see the line proceeds land and then move toward closing.
7. Close the DSCR purchase. The new loan applies its own leverage tier, credit floor, reserve requirement, and property eligibility.
8. Plan the exit. Typical exits are a refinance of the new property, paydown from rent growth or other income, or a sale. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The Consumer Financial Protection Bureau describes a HELOC as an open-end line you can borrow against repeatedly during a draw period. It also warns that you could lose the property if you cannot repay. In this strategy, that property is your existing rental. The Federal Trade Commission describes the same structure and the same collateral risk.
How Do You Size the Line?
Line room equals the property’s value times the lender’s CLTV cap, minus every recorded lien. That is the whole formula. The CFPB’s HELOC booklet shows the same subtraction, using 75% of appraised value as its example, and notes that lenders also weigh your income, debts, and credit history before setting the final limit. That 75% is a market-wide illustration. On the network, an investment-property line caps at 70% CLTV.
Run it as percentages. Say your rental carries a first mortgage equal to 50% of its value. At a 70% cap, you have room for a line equal to roughly 20% of the property’s value, before the $500,000 ceiling applies. If the mortgage sits at 60% of value, the room shrinks to about 10%.
Now compare that room to what the next purchase needs. Most DSCR purchases land at 75% to 80% loan-to-value (LTV) on a long-term rental, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with roughly a 700 or better score. Add closing costs and a reserve cushion on top of the down payment. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Line room on a lower-priced rental can cover the whole down payment on a purchase of similar price. On a higher-priced rental the same line may cover only part of it, so you will want other cash. Lines are also qualified on the interest-only payment calculated on the maximum draw. The maximum DTI is 50%, and credit profiles from 600 to 679 face a 45% limit. An investment line already requires 700 or better.
Because an investment line caps at $500,000, it falls in the automated valuation lane and commonly closes with no traditional appraisal. You can still request a full appraisal.
Will the Purchase Lender Accept Borrowed Down Payment?
It depends on the program, and you should find out before you draw. Across the wholesale network Lendmire places files with, lenders fall into three camps. Some accept documented line proceeds. Some cap the borrowed share and want a portion of seasoned cash of your own. A few require part of the down payment to be unborrowed. A plan that is 100% borrowed can fail on this point alone under the stricter programs.
Down payment and reserves are separate tests. Borrowed money may satisfy one and not the other. Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months.
Here is what else the DSCR lender checks on the new property:
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit: A 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
- Loan size: Standard programs go up to $3,000,000, and smaller balances are available through select lenders. Above $2,500,000 the network generally holds to 30-year fixed structures.
- Property type: Manufactured homes, log homes, and barndominiums are not offered.
A larger down payment lowers the payment and can lift the ratio. It never erases a leverage cap, a credit floor, or a reserve rule. The strongest files clear both tests: enough equity and enough rental coverage. Every figure here is a typical range, subject to lender guidelines and full file review.
Here is the trap that catches people. A DSCR above 1.00 only says rent covers PITIA. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Then your HELOC payment lands on top of all of it.
Can Your Plan Survive a Stress Test?
Before you draw, model what happens when something goes wrong. Layered borrowing means one problem can hit two properties at once. If the line covers the down payment and closing costs, borrowing against the deal approaches the full price. It is just split across two liens on two properties.
| Scenario | What happens | Who absorbs it |
|---|---|---|
| Base case | Rent covers PITIA and line payment | Rent |
| Line pricing floats up | Line payment grows | Your cash |
| Vacancy | No rent, both payments due | Your cash and reserves |
| Line frozen or reduced | Undrawn funds vanish | Your plan |
A variable line funds a purchase that sits on a typically fixed DSCR loan. That mismatch is real. When the draw period ends, repayment begins and the payment steps up, as the CFPB’s HELOC brochure explains. Test your personal cash flow with the new property vacant for a stretch, and with the line payment higher than today.
HELOC or Cash-Out Refinance?
If a rental HELOC is unavailable, or your rental is in an LLC, a DSCR cash-out refinance on the existing rental is the common alternative. It replaces your first mortgage rather than sitting behind it.
| Item | HELOC on rental | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Leverage cap | 70% CLTV, investment property | About 75% LTV, standard rental |
| Title | Individual or revocable trust | LLC possible, subject to program terms |
| Seasoning | Varies by lender | About 6 months is common |
| Pricing | Floats, never fixed | Fixed structures available |
A HELOC makes the most sense when you hold a first mortgage you want to keep and need a modest amount of cash. A cash-out refinance makes more sense when the need is large, the title is an LLC, or you want fixed pricing. Lendmire’s piece Using HELOC To Buy Rental Property covers the broader tradeoffs. This is a genuine judgment call, and the right answer depends on how much cheap first-lien debt you would be giving up.
Where Does This Plan Break?
Several edge cases can stop the plan even when the equity is there.
LLC title. An investment line cannot be written to an LLC, corporation, partnership, or land trust. Title must sit with you individually or in a revocable living trust. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out instead. Re-titling can carry legal, insurance, and due-on-sale consequences, so confirm with an attorney or title company first.
Lien position. On the network, a line can sit in first or second position. Some banks in the wider market insist on first position, which usually means a free-and-clear rental or paying off the existing loan.
Exposure limits. A borrower is limited to three lines. A borrower owning more than 15 financed properties is not eligible.
Ineligible property types. The investment line does not cover manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agricultural zoning. Single-family, 2-4 units, PUDs, townhomes, and condominiums are eligible.
Thin deals. If the new property barely clears coverage, adding line payments and a vacancy reserve can leave you underwater on real cash flow.
Variable against fixed. The line floats while the DSCR loan is usually fixed. A rise in the line’s pricing has no matching offset on the other side.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
What Should You Check Before You Draw?
- Confirm the collateral is titled to you or a revocable trust.
- Confirm your CLTV math leaves room under the 70% investment cap.
- Ask the DSCR lender in writing how borrowed funds are treated.
- Confirm your credit meets the 700 line floor and the DSCR program’s tier.
- Model the new property’s coverage and your personal cash flow with vacancy.
- Open and fund the line before going under contract.
- Draw only what you need, into a dedicated account.
- Write down your exit plan and a date to revisit it.
Frequently Asked Questions
Can I use a HELOC as my down payment?
Often yes, but it depends on the DSCR program. Some lenders accept documented line proceeds, some cap the borrowed share, and some want part of the down payment unborrowed. Ask before you draw, and expect to document the draw and show where the money landed.
Can a HELOC cover the whole purchase price?
Rarely. The DSCR purchase loan still has its own leverage tier, reserve requirement, and source-of-funds rules. Stricter programs reject a plan that is entirely borrowed. A cash-out refinance on the rental is the usual route when the need is larger. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Does the HELOC payment count against my DSCR?
Generally not. The ratio compares rent to the new property’s own PITIA, and a line secured by another property is not in it. DSCR files do not usually run a debt-to-income test. The payment still comes out of your actual cash flow, so stress-test it yourself.
Can a rental held in an LLC get a HELOC?
Not through the network’s investment line, which requires individual or revocable trust title. A rental already in an LLC typically needs a vesting change or a DSCR cash-out refinance, subject to program terms. Confirm any re-titling with an attorney first.
What if the lender freezes the line before I close?
Then the funds are gone and the purchase can fail. That is why you draw the cash into your own account before going under contract. Never rely on an undrawn line as your closing money.
