The Quick Read: A home-equity line can fund the down payment on a rental, but the plan runs on two separate loans: the line supplies cash secured by a property you already own, and the purchase lender must accept borrowed funds and approve the rental on its own merits.
- On an investment property, a HELOC tops out at 70% CLTV, with a $500,000 maximum line and a 700 minimum credit profile, subject to lender guidelines.
- The DSCR loan tests whether the rental’s rent covers its own payment. Your HELOC payment sits outside that ratio but still comes out of your pocket.
- Clearing 1.00 coverage is not the same as positive cash flow.
- Draw and document the money before you go under contract. An undrawn line is permission, not cash.
- Ask the purchase lender first whether borrowed funds count toward the down payment.
Key Terms Defined
HELOC (home equity line of credit): a revolving line secured by property you own. You draw cash as needed, up to a limit.
CLTV (combined loan-to-value): all loans secured by a property, added together, divided by its value.
LTV (loan-to-value): one loan divided by the property’s value. A purchase at 75% LTV means 25% down. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
DSCR (debt service coverage ratio): monthly rent divided by the property’s monthly payment. A result of 1.20 means rent covers the payment 1.2 times.
PITIA: principal, interest, taxes, insurance and any association dues. It is the full payment that DSCR divides into rent.
Draw period: the stretch when you can borrow from the line, usually paying interest only.
Seasoning: how long funds have sat in your account before a lender will treat them as your own.
Prepayment penalty: a fee some loans charge if you pay them off early.
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 Do the Two Loans Fit Together?
The HELOC does not buy the property. It hands you cash, and a separate DSCR loan finances the rental. Each lender approves you independently. Neither one answers for the other.
Picture the flow. You open a line against a property you already own. You draw cash. That cash lands in your bank account and becomes the down payment and closing costs on the rental. The DSCR lender then underwrites the rental itself.
The line lender does not control how you spend the money. The constraint comes from the purchase lender, which decides whether borrowed funds count as a down payment.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage. The property’s rent is the center of the file. Our complete DSCR loans guide covers that foundation in full.
Which Property Should Secure the Line?
You have two choices: your primary residence or a rental you already own. Both work. The risks differ.
A line on your home puts your residence behind the new rental. If rent falls short and the payments pile up, your house is the collateral. A line on an existing rental puts that rental at risk instead. Many investors prefer this, because it keeps the family home out of the deal.
On this network the two collateral types follow different rules:
| Factor | Line on an investment property | Line on a primary residence |
|---|---|---|
| Max CLTV | 70% | Up to 90%, only at 720+ credit |
| Max line | $500,000 | Up to $750,000 |
| Minimum credit | 700 | Lower floors apply by tier |
| Draw structure | 5-year draw, 25-year repayment | 3-year or 5-year draw options |
| Appraisal | Usually automated valuation | Full appraisal above $500,000 |
Two details trip people up. First, a primary-residence line above $500,000 caps at 75% CLTV and needs a full appraisal. Second, credit above 700 on an investment line buys eligibility, not extra leverage. Both 700 and 720 reach the same 70% ceiling.
All figures are typical guidelines from select wholesale partners. They are subject to lender review and are not a commitment to lend. This HELOC product is available in Lendmire’s 16 full-service states, a narrower footprint than the DSCR side.
How Big Should the Line Be?
Size the line to the deal, not to your maximum. The line is sized on the property that secures it: its value times the allowed CLTV, minus existing liens. The rental you are buying plays no part in the sizing.
Lines run from $25,000 to $750,000 on this network. At least 75% of the line is drawn at closing. That matters. If you open a $400,000 line to fund a $90,000 need, you still carry interest on most of the line from day one. Over-drawing is the most common sizing mistake. It adds payment with no purpose.
The line’s pricing floats during both the draw and the repayment period. It never converts to a fixed structure. Your HELOC payment can move even when your DSCR loan payment does not.
The HELOC is underwritten to you, not to the rental. Lenders look at credit, equity, existing liens and debt-to-income ratio. DTI maxes at 50%, and it is calculated on the interest-only payment at the maximum draw. Thin equity is the usual wall. A high first-lien balance can leave little or no room, so check this property by property.
Title matters too. The line must be held by you personally or by a revocable living trust. LLCs, corporations and partnerships cannot hold title. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.
Will the Purchase Lender Accept Borrowed Funds?
It depends on the lender. Treatment of borrowed down-payment money differs across the DSCR programs we place files with. Some accept it with documentation. Some limit the borrowed share. Some want a portion of the down payment from your own seasoned cash. The honest rule is to ask first.
Before you draw, put three questions to the loan officer:
1. Are borrowed funds accepted for the down payment at all?
2. Must any portion come from your own seasoned cash?
3. Can the same funds also count toward reserves?
That last one catches people. Down payment and reserves are separate tests. Borrowed money may satisfy one and not the other. Reserves are commonly around 6 months of PITIA, though they vary by lender, leverage, loan size and transaction type.
Seasoning is the other open question. Some loan officers like funds to sit in the bank for a period before contract. There is no universal number. Confirm it with your lender instead of guessing.
Document the trail. Keep the HELOC agreement, the draw confirmation and the bank statements showing the cash landing. Underwriters see where money comes from. Disclose the source. Never try to blur it.
Lendmire’s piece Using HELOC As Down Payment For Investment Property goes deeper on this sourcing step.
How Does the DSCR Loan Treat the HELOC?
The rental has to pass its own test. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal DTI is generally not part of that test. Your HELOC payment generally sits outside the ratio.
Here is where DSCR purchase files typically land across the network:
- Leverage: most files run 75%-80% LTV, meaning 20%-25% down. Select high-leverage programs reach 85% LTV with roughly a 700+ score.
- Coverage: 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted.
- Credit: a 620 floor exists in parts of the network. Most programs want around 660. A 700+ score unlocks the strongest leverage tiers.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000 the network generally holds to 30-year fixed structures.
- Terms: the 30-year fixed is the spine. Extended 40-year terms and interest-only periods are available through select lenders, and ARM structures exist too.
DSCR loans to LLC borrowers are available subject to lender program eligibility. This is the sharpest structural difference from the HELOC, which cannot be held in an LLC. Across our 41 markets, including Washington, D.C., that mismatch shows up often.
Two tests, then. The rental must cover its payment. And you must be able to carry the HELOC. Passing one does not excuse the other. Plenty of equity does not fix thin rent coverage, and strong rent does not fix thin equity.
What Does the Math Look Like?
The math gets tight because the DSCR ratio leaves out the HELOC. Run the numbers on a modeled example (assumptions, not market data).
Say you buy a rental at 75% LTV, with the 25% down payment fully drawn from a HELOC. Assume the rent covers the DSCR loan’s full PITIA at about 1.15x. On paper, that clears a 1.00 floor. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Now add the HELOC payment on the borrowed 25%. The line is interest-only during the draw period, so the payment is smaller than the main loan’s. Even so, it lands on top. In this modeled case, the all-in coverage drops to roughly 0.95x. The deal passes DSCR and still loses money every month.
That is the central trap. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses all sit outside it. So clearing 1.00 is not “positive cash flow.” Add a variable HELOC payment on top, and the cushion thins further.
Combined leverage adds a second risk. A DSCR purchase at 75%-80% LTV plus a fully borrowed down payment means you finance close to the whole purchase. A small drop in rent or a cost spike has nowhere to land. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The strongest versions of this plan have the opposite shape. Rent covers both the DSCR payment and the HELOC payment, with room to spare. The investor also holds separate savings for reserves. The weaker files lean on the HELOC for everything and hope.
Step by Step: From Equity Check to Paydown
1. Check your equity. Take the collateral’s value, apply the allowed CLTV, subtract existing liens.
2. Pick the collateral. Decide whether the home or an existing rental stands behind the line.
3. Call the purchase lender. Confirm whether borrowed funds count and whether reserves must be unborrowed.
4. Open and draw the line before contract. Leave the funds documented in your account.
5. Run both tests. Check the rental’s coverage, then add your HELOC payment on top.
6. Close the DSCR purchase. The rental lender reviews the property’s rental income on its own terms.
7. Plan the paydown. Pay the line down from rent or savings, or refinance later.
On step 7, one common exit is a cash-out refinance once value and seasoning allow it. On this network, cash-out tops out around 75% LTV on standard rentals, and about 6 months of seasoning is the common expectation. Watch for a prepayment penalty on the DSCR loan. If one applies, an early refinance gets more expensive. See Lendmire’s explanation of using HELOC for down payment on investment property for more on this. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Where the Rule Breaks
A frozen line. A HELOC is not guaranteed money. The CFPB’s HELOC brochure explains that lenders can freeze or reduce a line if the home’s value falls or your finances worsen. The Federal Reserve’s HELOC tips add that a freeze can happen even with a good payment record, and the lender must send written notice afterward. That is why you draw before contract. Never count on a line you have not drawn.
An LLC-held property. The line will not close on a property titled in an LLC. Fix the vesting first, or use a DSCR cash-out refinance instead.
Ineligible property types. The HELOC does not cover manufactured homes, co-ops, condotels, log homes, commercial, mixed-use or agricultural-zoned properties. On the DSCR side, manufactured homes (single- and double-wide), log homes and barndominiums are not offered either.
Exposure caps. A borrower is limited to three lines on this network, and an investor with more than 15 financed properties is not eligible. A portfolio investor can hit that ceiling before running out of equity.
Thin equity. Passing DSCR does not create equity. Both tests must clear, or neither loan moves.
Tax questions. 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.
Is It the Right Move for You?
It fits best on long holds with strong rent coverage. It fits worst on short holds or thin deals.
| Situation | Fit | Why |
|---|---|---|
| Long hold, rent clears both payments | Good | The line gets paid down from cash flow |
| Plan to refinance and pay down the line | Moderate | Depends on value, seasoning and any prepayment penalty |
| Short hold or flip | Poor | Stacked debt cost can outrun the gain |
| Rent only just clears 1.00 | Poor | The HELOC payment pushes the deal underwater |
| Plenty of cash, wants to keep it liquid | Case by case | Borrowed funds may not count toward reserves |
Alternatives worth comparing:
| Option | Best when | Watch out for |
|---|---|---|
| Cash down | You hold idle savings | Drains your liquidity |
| HELOC on your home | You have deep equity and strong income | Your residence backs the rental |
| HELOC on an existing rental | You want to keep the home clear | 70% CLTV cap, $500,000 maximum |
| DSCR cash-out refinance | A rental has seasoned and gained value | Seasoning and combined leverage limits |
The decision is a risk call. Bring the HELOC in as a down payment only if both loans work with rent alone and your cash reserves stay separate.
Frequently Asked Questions
Do I have to tell the DSCR lender the money came from a HELOC?
Yes. Underwriters review bank statements and see where large deposits come from. Disclose the source and keep the HELOC agreement and draw confirmation. Trying to obscure it can sink the file.
Can I use equity from a rental I already own?
Yes, in many cases. On this network an investment-property line caps at 70% CLTV, with a $500,000 maximum and a 700 minimum credit profile. The property must be titled in your name or a revocable living trust, not an LLC. Everything remains subject to lender guidelines.
Does HELOC cash also cover closing costs and reserves?
Cash is cash, but the purchase lender decides what counts. Some programs accept borrowed funds for the down payment and closing costs but want reserves from your own money. Ask about both before you draw.
What if the rent doesn’t cover the HELOC payment too?
You pay the gap from savings. That is the main risk of the strategy. Options include paying the line down with other funds, refinancing, or selling. A sub-1.00 DSCR path is available through select lenders in the network, with leverage and terms adjusted, but it does not remove the HELOC payment.
Can self-employed investors use this approach?
Often, yes. The HELOC can qualify on documented income under the applicable program, subject to lender guidelines. Bank-statement deposit analysis needs a 680 minimum, but investment lines already floor at 700, so it is never the binding limit. The DSCR loan itself qualifies primarily on rental income.
