The Quick Read: A home equity line of credit (HELOC) on the home you live in can fund the down payment on a rental, but it supplies cash only, a separate DSCR loan buys the property, and the plan works when you keep equity after the draw, rent covers the loan with room to spare, and the purchase lender accepts borrowed funds.
- Two loans, two underwriters. The line is reviewed on your credit, equity, and debt ratios. The DSCR loan (debt service coverage ratio, meaning monthly rent compared with the full monthly payment) is reviewed on the property.
- Timing matters. You can’t open a line on a property you haven’t bought. The line has to exist before you go under contract.
- Leverage is capped on both sides. Across Lendmire’s wholesale network, a primary-residence line reaches up to 90% CLTV only at a 720-or-better credit profile. Purchase loans mostly land at 75%-80% LTV.
- Coverage is not cash flow. Clearing 1.00 on the DSCR does not mean the rental pays you. The line payment sits on top.
- Your home is the collateral. A bad rental year can become a problem for the house. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
What This Strategy Actually Is
The strategy borrows against equity in the home you live in, then uses that cash to buy an investment property. A HELOC is a revolving line of credit secured by your home. It does not buy anything on its own. It hands you cash, and a second loan closes the purchase.
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.
That second loan is often a DSCR loan. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Your W-2 story matters less there. It matters a lot on the line.
Here’s the catch: two lenders, two files, and neither approval promises the other. A strong rental can’t rescue thin equity. Plenty of equity can’t rescue a property whose rent barely covers its payment. The strongest files clear both tests.
A quick note on the business side. 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.
For the full picture of how the purchase side works, Lendmire’s complete DSCR loans guide covers it from the ground up. This article stays on the line and the decision around it.
Key Terms Defined
HELOC: A revolving credit line secured by your home. You borrow against it during a draw period, then repay during a set repayment period.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value. It measures how much of the home is borrowed against in total.
DSCR: Monthly rent divided by the monthly debt service on the rental. Lenders use it to judge whether the property carries its own payment.
PITIA: Principal, interest, taxes, insurance, and any HOA dues. It is the payment the DSCR formula divides into rent.
Draw period: The stretch when you can pull money from the line, usually paying only interest.
Lien position: Where a loan stands in line for repayment if the property is sold to cover debt. A first lien is paid before a second lien.
Vesting: How title to a property is held, such as in your own name, a revocable trust, or an LLC.
How Each Loan Gets Underwritten, Step by Step
The sequence runs line first, deposit second, purchase third. Each step has its own test, and skipping the questions at step three is the most common way this plan stalls.
Step 1: Size the line. Take the home’s value, multiply by the CLTV ceiling, and subtract what you owe on the first mortgage. That is your maximum room. On this network, a primary-residence line tops out at 90% CLTV, and that tier exists only at a 720-or-better credit profile. Lower credit scores carry lower ceilings.
An investment-property line, by contrast, tops out at 70% CLTV and $500,000. Don’t confuse the two. Your home is the primary residence in this plan, so the primary-residence table applies.
Step 2: Pass the line’s own test. The line is underwritten to you. The lender reviews credit, equity, existing liens, and your debt-to-income ratio (DTI, the share of monthly income that goes to debts). Across the network, DTI tops out at 50%, with 45% for credit profiles from 600 to 679. A ratio above 45% requires a 680 minimum. The payment is qualified on the interest-only amount at the maximum draw, so the lender tests you against a fully drawn line.
Credit works on a single-bureau score keyed to the primary wage earner, with a 600 program floor. The report can be no more than 90 days old at closing. Lines at or below $500,000 usually rely on automated valuation instead of a full appraisal. Anything above $500,000 requires a full appraisal.
Step 3: Ask the purchase lender before you draw. This is the step people skip. Whether borrowed money counts toward the DSCR down payment depends on the program. Across the wholesale network, we see three camps:
1. Some lenders accept documented line proceeds as down payment funds.
2. Others cap the borrowed share and want a slice of the down payment from your own seasoned cash.
3. The strictest require that slice to be fully unborrowed.
Seasoned means the money has sat in your account for a set period. Ask which camp your lender falls in before the money moves.
Step 4: Draw, deposit, document. The paper trail runs from the line to your account to escrow. Expect to provide the line’s closing documents, the draw confirmation, and bank statements showing where the cash landed. Unexplained large deposits create conditions. Wiring the draw straight into a clean account, then leaving it alone, keeps the trail short.
Step 5: The DSCR loan gets its own review. The ratio is monthly rent divided by PITIA. The line payment generally isn’t in that formula. (It still comes out of your pocket, which is the point of the next section.) Purchase files mostly land at 75%-80% LTV, meaning 20%-25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700+ score.
Coverage of 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 more leverage. Credit follows a similar ladder: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
Step 6: Reserves are a separate test. Reserves are cash left over after closing. They vary by lender, leverage, loan size, and transaction type, and commonly run around 6 months of PITIA. Conservative files at modest leverage under $1,500,000 can see them waived. Larger loans typically step up to about 9 months. Borrowed funds often can’t cover both the down payment and the reserves, so one dollar of line can’t do two jobs.
Structures and Variations
The line itself comes in a few shapes, and the shape changes your payment story more than most borrowers expect.
On primary residences and second homes, two draw structures exist across the network. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other, the longer-runway program, has a 5-year draw followed by a 25-year repayment. At least 75% of the line is drawn at closing on both. Pricing floats through the draw and repayment periods and never converts to fixed.
That 75% draw has a practical edge. You start paying on most of the line on day one, whether or not the rental is under contract yet. Size the line to the need, not to the maximum.
Line sizes run $25,000 to $750,000. Anything above $500,000 is primary-residence only and needs a full appraisal. It requires 700 or better (720 on the longer-runway program), and caps at 75% CLTV. A borrower can hold up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties isn’t eligible. Lendmire’s HELOC placements run through 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C.
Here is how the three common equity routes compare:
| Factor | Line on your home | Line on a rental | DSCR cash-out refinance |
|---|---|---|---|
| Collateral at risk | Your primary home | The rental | The rental |
| What is underwritten | You: credit, DTI | You: credit, DTI | Property rent vs. payment |
| Title requirement | Individual or revocable trust | Individual or revocable trust | LLC possible, per program |
| Typical leverage ceiling | Up to 90% CLTV at 720+ | 70% CLTV, $500,000 max | About 75% LTV |
| Loan type | Second or first lien line | Second or first lien line | Replaces the first loan |
On that last column: DSCR cash-out refinances top out around 75% LTV on standard rentals, and 70% on short-term-rental collateral, with about 6 months of seasoning as the common expectation. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Where the General Rule Breaks
The general rule says an equity line on your home funds a rental down payment. Several edge cases bend it.
The home’s own line terms. Check whether the line allows rental activity at all. The CFPB’s HELOC brochure warns that renting your home out to other people may be prohibited under the terms of your line of credit. That matters if you plan to house-hack, or move out and rent the home you borrowed against. Read the line agreement before you build the plan around it.
The draw-period cliff. When the draw ends, borrowing stops and the payment starts paying down principal. Pricing floats the whole way, so the payment can change as well. Say the rental needs a year of stabilizing. A 3-year draw gives you less room than a 5-year draw does.
Value drops. The same agency notes that if the home’s value drops significantly, the lender might decide not to allow additional credit under the plan. The CFPB explanation of a HELOC also states plainly that falling behind on the loan could cost you your home. A line you expected to use for repairs can freeze at the wrong moment.
LLC-titled rentals. The line must sit on title held by an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts can’t hold title. Your primary home is usually in your own name, so that part is fine. But a rental already deeded to an LLC can’t take a line without a vesting change. The cleaner route there is a DSCR cash-out. DSCR loans can often be titled in an LLC, subject to lender program eligibility.
Second-lien limits on DSCR. A DSCR loan generally can’t sit behind another loan in second-lien position. So rental equity is usually tapped through a first-lien cash-out refinance, not a second line.
Conventional loans. If the rental is bought with a standard DTI-based mortgage, the new line payment lands in your debts and can break the ratio. DSCR sidesteps that formula, though a lender may still look at your overall debt picture.
A paid-off home. No mortgage doesn’t make the money free. The line is still secured by your house.
Converting the home to a rental later. Moving out and renting the home you borrowed against raises two questions at once: what the line agreement allows, and how a purchase lender sees the change in occupancy. Ask both before you move.
Property types. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs. The line’s property list is similar: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.
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.
When the Answer Is Yes
The answer leans yes when most of these are true:
- Equity survives the draw. After the line, your CLTV stays comfortably below the ceiling, not pinned to it. Pinned files tolerate no drop in value.
- The rental clears coverage with room. Coverage sits well above 1.00 on documented rent, not optimistic rent.
- Reserves live outside the line. You hold cash for the DSCR loan’s reserve requirement that you didn’t borrow.
- The purchase lender accepts borrowed funds. You asked, in writing, before drawing.
- The line payment fits your income alone. If the rental sat empty for months, your primary income would still carry both obligations.
- Your credit clears both ladders. A 720+ profile for the top line tier. Roughly 660 or better for the purchase loan, with 700+ for the strongest leverage.
- You have a plan beyond the draw period. That could be a refinance or paydown. The rental has to stabilize before the draw ends. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
When the Answer Is No
The answer leans no when any of these show up. Skip it, or restructure.
- Thin equity. If the home’s remaining room can’t cover a 20%-25% down payment plus closing costs and reserves, the plan is a stretch from the start.
- Rent is a hope, not a lease. A property that clears 1.00 only on a stretch rent assumption belongs in the pile for more stress testing.
- No cash outside the line. Borrowed money often can’t count toward both the down payment and reserves. If you have no separate reserves, you have a gap.
- The line payment would strain your household. The loan is reviewed for you at interest-only on the maximum draw, but real life is messier.
- Variable income. The line is underwritten to you. A shaky year at work shows up in the line first.
- The purchase lender caps or excludes borrowed funds and you have no seasoned cash of your own.
- A line agreement that restricts rental use of the home you borrowed against.
This one’s a genuine judgment call for many borrowers. The numbers might pass every box above, and the investor might still not want the home on the line. That is a risk question, not a math question.
A Worked Example in Percentages and Ratios
Run the numbers this way. These are modeled assumptions, not market data.
Say your primary home carries a first mortgage equal to 50% of its value, and your credit sits at 720+. The ceiling is 90% CLTV. That leaves room equal to 40% of the home’s value, before DTI and valuation checks. Say the rental you want is priced at 80% of the home’s value, and the purchase loan asks for 25% down. The down payment equals 20% of the home’s value. Closing costs and reserves come on top. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The line fits, with room to spare. But sizing the line to the maximum would put at least 75% of it on your books at closing. Smaller is cleaner.
Now the rental side. Assume coverage of 1.15x on documented rent. That clears the 1.00 floor many select programs start from. Stress it: knock 15% off collected rent for a vacant stretch, and coverage falls to roughly 0.98x. Repairs, management, utilities, and capex sit outside the DSCR calculation entirely. Then the line payment lands on top.
So the question for this file is not whether it qualifies. It is whether you can absorb a rough quarter while paying interest on borrowed down payment funds. Thinking it through, the stronger move might be a smaller line and a larger share of your own seasoned cash, though an investor with abundant equity and stable income could reasonably argue the other way.
Now flip it. Same credit, but your first mortgage equals 80% of the home’s value. Room under the ceiling is 10% of the home’s value. If the rental is priced at 60% of the home’s value, a 25% down payment equals 15%. The line can’t cover it. That file waits, or shifts to a DSCR cash-out on a rental you already own. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What Lenders Look For When You Draw
Across the network, purchase lenders tend to care about four things on the funds trail:
1. Source. They want to see the line closing documents, not just a deposit.
2. Seasoning. Some want funds sitting in your account for a set period before the contract.
3. Cap. Some limit the borrowed share of the down payment.
4. Clean paper. Large unexplained deposits create conditions. Transfers between your own accounts also deserve a note.
Practitioner habit: get the purchase lender’s position on borrowed funds in writing before the line closes. The wrong answer after the draw is expensive.

Frequently Asked Questions
Can a HELOC cover the whole purchase price of a rental?
Usually not. Lines top out at 90% CLTV on a primary residence at 720+, and the line is capped at $750,000 in total. For most borrowers the line funds a down payment and closing costs, and a DSCR loan covers the rest. Even with large equity, the more of the purchase you borrow against your home, the more of the house you’ve put behind the rental.
Does the HELOC payment count in my DSCR?
Generally not. The DSCR formula divides monthly rent by PITIA on the rental alone. The line payment still comes out of your cash flow, and a lender may look at your overall debt picture. On the line side, the payment is tested on the interest-only amount at the maximum draw against your DTI.
Will a DSCR lender accept borrowed money for the down payment?
It depends on the program. Some accept documented line proceeds. Others cap the borrowed share and want part of the down payment from your own seasoned cash. The strictest need that part fully unborrowed. Ask before you draw, and keep the paper trail from the line to escrow.
Can I hold the rental in an LLC if I use a home equity line?
Often yes on the DSCR side, subject to program terms. The line, though, must be secured by title held by an individual or a revocable living trust. Since the line sits on your primary home and not on the rental, the two can coexist. A line on a rental already deeded to an LLC needs a vesting change first.
What credit score do I need?
For the line, 600 is the program floor, and 720 or better is required for the 90% CLTV tier on a primary residence. For the DSCR purchase loan, a 620 floor exists in parts of the network. Most programs want around 660, and 700+ unlocks the strongest leverage tiers.
