The Quick Read: A home equity line of credit (HELOC) can fund the down payment and closing costs on a rental, but only when it is secured by a property you already own, and a separate debt service coverage ratio (DSCR) loan then buys the new property. You end up with two lenders, two approvals, and two debts.
- The line reads you: credit, equity, existing liens, and debt load. The DSCR loan reads the property: rent against its monthly obligation, plus credit, leverage, and reserves.
- On an investment property, the lines Lendmire places through its wholesale network cap at 70% combined loan-to-value, need a 700 credit score, and top out at $500,000.
- The DSCR ratio does not count the HELOC payment, so a passing ratio does not mean the deal cash flows.
- Borrowed funds are treated differently by each DSCR program, and often differently for the down payment, closing costs, and reserves.
- Total borrowing can approach 100% of the purchase price, spread across two liens on two properties.
What a HELOC Does (and Does Not Do) in a Rental Purchase
A HELOC is a pool of cash, not a purchase loan. You borrow against equity, which is a property’s value minus what you owe on it. You can draw, repay, and draw again up to the limit during a set window called the draw period.
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 structure explains the first rule. The line has to sit on something you already own. You cannot open it on the rental you are about to buy, because that property has no equity to borrow against yet.
So the sequence is two separate transactions. The line releases cash from property one. A DSCR loan then finances property two. The cash from the line becomes your down payment or closing costs.
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.
Investors short on cash like this idea for an obvious reason. It converts trapped equity into purchase money without selling anything. The catch is that you are now financing close to 100% of the deal, and your first property carries the risk.
How Underwriting Treats It, Step by Step
Each lender looks at a different thing, and each approval can fail on its own. Here is the order in which a file typically moves.
Step 1: Size the line on the property you own. The math is value times the combined loan-to-value cap, minus existing liens, up to the program ceiling. Lenders work this out one property at a time. Equity is never pooled across your portfolio.
Step 2: The HELOC underwrites you. The line reviews your credit, the equity, existing liens, and your debt load. Debt-to-income tops out at 50% in the network’s lines, and the payment is figured on the interest-only amount at the maximum draw. That means the line is judged as if you borrowed all of it.
Step 3: You draw the cash. During the draw period, payments are typically interest-only. On a variable-rate line, payments can change even if you borrow nothing more.
Step 4: You build the paper trail. A DSCR lender wants proof that the money is real and traceable. Expect to supply:
- the HELOC closing documents and the draw confirmation;
- statements showing the cash landing in your account;
- a credit report that shows the new line as a liability;
- a lease or rent schedule, an appraisal, and insurance on the new property.
Step 5: The DSCR loan buys the property. The ratio is the property’s monthly rent divided by its own monthly obligation: principal, interest, taxes, insurance, and any association dues, together called PITIA. Your HELOC payment generally sits outside that math. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Step 6: The line starts floating with its index. A HELOC rate is a benchmark index plus a margin. The CFPB’s HELOC booklet names the U.S. prime rate and the constant-maturity Treasury rate as common indexes. It also warns that some line agreements restrict renting out the secured property, so read yours before you assume anything.
Across the programs Lendmire places, most DSCR purchase files land at 75% to 80% LTV, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with roughly a 700-plus score. That down payment is the gap the HELOC is being asked to fill. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Which Property Should Secure the Line?
Your primary residence usually offers more leverage on paper, while an existing rental keeps your home out of the deal. The table compares the two on the network’s investment and primary-residence lines. Every figure is subject to lender guidelines and full file review.
| Factor | Line on an existing rental | Line on your primary home |
|---|---|---|
| Max combined LTV | 70% | Up to 90%, only at 720+ credit |
| Minimum credit | 700 | Varies by program |
| Max line size | $500,000 | Larger lines exist, primary only |
| Draw structure | 5-year draw, 25-year repay | 3/17 or 5/25 structures |
| What you risk | The rental | Your home |
Investment lines run only the 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats through both phases and never converts to fixed on this network.
Compare that with what NerdWallet describes for rental-secured lines in the wider market: a 10-year draw, typically interest-only at a variable rate, then up to about 20 years of principal and interest. The network figure for an investment line is the 5-year draw and 25-year repayment above. Lenders may offer a fixed-rate conversion, so the contract decides.
A few practical limits shape which property you can use:
- Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable ones) are eligible.
- Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not offered.
- Title must be held by you personally or by a revocable living trust. An LLC cannot hold title on the line, which is the sharpest difference from a DSCR loan. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
- An investment line above 70% combined loan-to-value does not exist on this network. Credit above 700 buys eligibility, not extra leverage.
- A borrower is limited to three lines and cannot own more than 15 financed properties.
- Lendmire’s home equity lines are available in 16 states, a narrower footprint than its 41-market DSCR platform, which includes Washington, D.C.
Because an investment line caps at $500,000, it runs on an automated valuation and commonly closes without a traditional appraisal. You can still request a full appraisal.
What the Borrowed Money Can Cover
Think of three separate buckets: the down payment, the closing costs, and the reserves. A DSCR program can treat borrowed money differently in each one. This is where files stall, so it is worth knowing before you draw.
Across the network, programs fall into roughly three camps:
1. Some accept documented HELOC proceeds without much fuss.
2. Some cap the borrowed share of the down payment.
3. Some require a slice of your own unborrowed, seasoned cash.
Reserves are a separate test. Reserves are the months of PITIA you must hold in liquid assets after closing. They vary by lender, leverage, loan size, and transaction type, and commonly run around 6 months. Conservative rate-term files at modest leverage under $1,500,000 can see them waived, while loans above that size typically step up to about 9 months. Borrowed money may count for the down payment yet be excluded from reserves, and undrawn credit generally does not count at all.
An undrawn line is permission to borrow, not committed money. A lender can freeze it. If your plan depends on drawing after the contract is signed, you are exposed.
| Bucket | Typical question to ask the DSCR lender |
|---|---|
| Down payment (often 20%-25% of price) | Is borrowed money accepted, and up to what share? |
| Closing costs | Can the draw cover them? |
| Reserves | Must these come from your own seasoned funds? |
| Repairs and vacancy cushion | Not part of the loan test, but real |
Does the Rental Still Cash Flow? Stress-Test It.
A passing DSCR can sit on top of a deal that loses money every month. The ratio compares rent to the subject property’s PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it, and so does your HELOC payment.
Run the numbers on a rental bought at 75% LTV, where the rent covers its PITIA at about 1.2x. The HELOC pays the 25% down payment. The lender reports 1.2x and moves on. You, though, also owe the line’s interest-only payment, and that payment was never asked of the rent. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Now add one slow leasing month. If rent drops 10%, coverage falls from 1.2x to roughly 1.08x before you pay a repair bill. Count the line payment on top and your combined coverage can slip below 1.00. The lender’s ratio looks fine, but your bank account does not.
Here is a quick self-test. Add the HELOC payment to the new property’s PITIA, then ask whether the rent covers both with room for vacancy and repairs. If it does not, the money has to come from your job or savings. That may be fine, but make the choice deliberately.
Two more exposures matter:
- Floating payments. On a variable plan, payments can rise even if you borrow nothing more, according to the CFPB’s HELOC booklet.
- The end of the draw. Experian notes that repayment-phase payments include principal and interest, so many borrowers see them more than double compared with interest-only. Some lines also carry a balloon payment when the draw ends.
If the line sits on your primary home, the stakes are higher. The CFPB states plainly that you could lose your home if you cannot repay the line on schedule.
Lenders in the network also look at coverage differently. 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. None of that changes the cash-flow picture above.
HELOC, Home Equity Loan, or Cash-Out Refinance?
Each product releases equity, but they differ in how you draw and repay. The right choice depends on whether you want flexibility or a fixed lump sum.
| Feature | HELOC | Home equity loan | Cash-out refinance |
|---|---|---|---|
| How you get cash | Draw as needed | One lump sum | One lump sum |
| Effect on current loan | Sits beside it | Sits beside it | Replaces it |
| Payment structure | Interest-only draw, then amortizing | Fixed repayment | New full repayment |
| Best for | Staged or uncertain spending | Known, one-time cost | Resetting the whole mortgage |
A cash-out refinance on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. On short-term-rental collateral the cash-out ceiling is 70%. If your main goal is a down payment and the existing mortgage is one you want to keep, the line is usually the lighter touch. If you plan to recycle equity through renovations, see Lendmire’s piece Revolving Investment HELOC vs Cash-Out Refinance for BRRRR Investors.
BRRRR means buy, rehab, rent, refinance, repeat. It is the strategy where a HELOC fits best, because the refinance repays the line. For a buy-and-hold down payment, there is no built-in repayment event. You are financing the whole deal and hoping the rent carries it.
Where the General Rule Breaks
The usual rule is that the line supplies the down payment and the DSCR loan buys the property. These cases bend it.
Prepayment penalties. Many DSCR programs carry a step-down prepayment penalty. If you plan to buy and then refinance early to retire the HELOC, check the penalty schedule first. An early exit can cost more than the interest you meant to save.
Frozen lines. A lender can freeze or reduce an undrawn line. Draw before you go under contract, not after.
Vesting. A rental held in an LLC cannot secure the line. The usual fix is a vesting change, subject to lender program eligibility, or a DSCR cash-out refinance instead.
Property eligibility. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s programs. A line secured by one of these will not help you buy a rental that cannot be financed anyway.
Leverage stacking. A strong file clears both tests: enough equity for the line, and enough rental coverage for the loan. A larger down payment lowers the monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. A good DSCR does not fix thin equity, and thin equity is not fixed by good coverage.
Experience from the file desk. In DSCR files funded partly by a HELOC, the common snag is sequencing, not the ratio. The borrower draws late, the statements do not show the cash seasoned in an account, and the DSCR lender asks for another round of documents. Drawing early and keeping a clean paper trail from line to account to escrow prevents most of that.
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.
Who This Fits (and Who Should Skip It)
It is often a strong fit for investors with real equity, steady income, and a rental that clears its own debt with room to spare. It is a poor fit if the plan only works when everything goes right.
It tends to fit if:
- You already hold a property with enough equity to reach the 70% combined loan-to-value ceiling with room left over.
- Your credit sits at 700 or above.
- The new rental’s coverage is comfortably above the program minimum, not at it.
- You have reserves in your own seasoned funds, apart from the line.
- You can absorb the HELOC payment from outside income if the rental has a bad stretch.
Skip it, or rethink the structure, if:
- The deal only works at the bare minimum coverage ratio.
- Your reserves exist only as undrawn credit.
- The line sits on your home and a missed payment would put your household at risk.
- You are counting on a quick sale to repay the line.
A cautious investor who spoke to HELN News advised against using a home to finance a first deal, and an agent there said the approach can serve short-term strategies like BRRRR but may not be sustainable over the long term. Reasonable people can land on either side of that. A seasoned landlord with a rehab plan and a refinance exit is making a different bet than a first-time buyer financing 100% of a long-term rental.
For investors who plan to hold, a lower-leverage purchase with cash they own often beats the stacked structure. Think of it as buying a smaller property or putting down more of your own money. The cleaner structure may return less on paper but gives you a margin for error.

Key Terms Defined
Combined loan-to-value (CLTV): all loans secured by a property, added together, divided by the property’s value.
Draw period: the window when you can borrow from the line, usually with interest-only payments.
Repayment period: the phase after the draw ends, when you pay down principal and interest.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly obligation on a property.
Lien: a lender’s legal claim on a property until the debt is repaid.
Reserves: liquid assets, counted in months of PITIA, that a lender wants you to hold after closing.
Frequently Asked Questions
Can a HELOC cover the entire purchase of an investment property?
Not on this network. The line supplies the down payment and closing costs, while the DSCR loan has its own leverage tier, reserves, and source-of-funds rules. Most DSCR purchase files land at 75% to 80% LTV, so the loan finances most of the price and the line fills the equity gap. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Does the HELOC payment count against my DSCR?
Generally no. The ratio compares rent to the subject property’s own PITIA. The line still counts as a liability on your credit report, and a lender may review it in the credit and debt picture. That is why a passing ratio can hide a deal that does not cash flow after the line.
Can I get a HELOC on the property I am about to buy?
No, not before you own it with equity in it. The line has to come from something you already own, such as your home or an existing rental. On this network, an investment line caps at 70% combined loan-to-value and $500,000.
Will a DSCR lender accept borrowed money for reserves?
Often not. Borrowed funds may be accepted for the down payment or closing costs but excluded from reserves, and undrawn credit generally does not count. Reserves commonly run around 6 months of PITIA, depending on the lender, leverage, loan size, and transaction type.
What happens when the draw period ends?
The payment shifts from interest-only to principal and interest, and it can rise sharply. On the investment lines Lendmire places, the draw runs 5 years and repayment runs 25 years, with pricing that floats throughout. Plan a repayment path, such as a refinance or a sale, before the draw ends.
