Using a HELOC to Invest in Rental Properties

The Quick Read: A home equity line of credit supplies cash for a rental purchase but does not buy the property, so the investor still needs a second approval on the acquisition loan, and the strongest files pair enough equity for the draw with enough rental coverage on the new property to carry its own payment. The line funds the down payment, closing costs, or repairs. A separate loan, or an all-cash purchase, closes the deal.

• A line on your primary residence can reach up to 90% combined loan-to-value (CLTV) in Lendmire’s network, but only at a 720-or-better credit profile. A line on a rental property tops out at 70% CLTV and $500,000.
• The line is a second debt. The new rental’s debt coverage ratio (DSCR) generally does not include it, but your cash flow still pays it.
• Payments on the line can change even when you draw nothing more, and the draw period ends.
• Rental coverage above 1.00 is not the same as positive cash flow.
• Whether the acquisition lender accepts borrowed funds as a down payment is the question that sinks the most plans.

What Does a HELOC Actually Do in a Rental Purchase?

It converts equity you already hold into cash you can move. Yahoo Finance defines equity as a home’s value minus the outstanding mortgage, and notes that homeowners can put it toward the down payment on an investment property if they have enough of it to qualify.

That is the whole job. The line is a revolving balance secured by real estate you own. You draw, you pay interest on what you drew, and you repay on a schedule. It does not carry a purchase contract, it does not read the rental’s income, and it does not replace the loan on the new property.

The most common shape of the strategy has three layers. The investor keeps the first mortgage on the primary home. A line sits behind it. A new loan, often a DSCR loan, finances the rental. Three obligations now sit on the investor’s balance sheet, and every one of them needs a paying source.

How Underwriting Treats the Line: Step by Step

Underwriting happens twice. One lender reads you and your equity. A second lender reads the rental. Mixing those two reviews up is the most common planning error.

1. Size the equity. Start with appraised value times the maximum CLTV, then subtract what you owe on existing liens. A primary home with a first mortgage at 60% of value, on a program that allows up to 90% CLTV at a 720-or-better profile, leaves room of roughly 30% of value before line-size caps. On a rental property, the same math runs against a 70% CLTV ceiling.

2. Qualify the borrower for the line. Across the network’s HELOC options, the credit floor is 600 on the program overall, a single-bureau score is pulled, and the report cannot be more than 90 days old at closing. Maximum DTI is 50%. Profiles from 600 to 679 are held to 45%, and anything above 45% needs a 680 minimum. The payment used in that test is the interest-only payment on the maximum draw, not on what you plan to use.

3. Close and draw. At least 75% of the line is drawn at closing, so interest starts on most of the balance right away. A line is not a free option you open and ignore. Draw into your own account and keep the statements.

4. Move the money by a documented path. Transfer from the line to your account, then to the title company. Keep the paper trail clean. The acquisition lender will ask where the down payment came from.

5. Qualify the rental on the acquisition loan. On a DSCR loan, the ratio is monthly rent divided by the property’s PITIA (principal, interest, taxes, insurance, and any HOA dues). On a conventional loan, the line’s payment counts in your debt-to-income ratio. A BiggerPockets discussion of the downsides makes the same point about conventional underwriting.

6. Plan the exit. Pay the line down from rent, from savings, or by refinancing the new property and retiring the line at that closing. If you pick the refinance, check whether the first loan carries a prepayment penalty before you count on it.

Key Terms Defined

CLTV (combined loan-to-value): All liens on the property added together and divided by its value.

Draw period: The stretch when you can borrow against the line and pay only interest.

Repayment period: The stretch after the draw ends, when the balance amortizes and no new advances are allowed.

DSCR: The monthly rent divided by the monthly PITIA, used to judge whether a rental carries its own payment.

PITIA: Principal, interest, taxes, insurance, and association dues on the property.

Seasoning: The time a deposit or ownership has been in place before a lender counts it.

Which Property Secures the Line?

The collateral changes nearly everything. Lendmire brokers HELOCs through select wholesale partners, and the ceilings depend on occupancy.

On a primary home, a line above $500,000 needs a full appraisal, a 700 credit profile (720 on the longer-runway structure), and caps at 75% CLTV. An investment line at or under $500,000 ordinarily runs on an automated valuation, so a traditional appraisal is usually not required, though a borrower can ask for one.

Title is the sharpest difference from a DSCR loan. A HELOC must be held by an individual or a revocable living trust. LLCs, corporations, and partnerships cannot hold title. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out instead. The DSCR side can close in an LLC, subject to lender program eligibility.

Texas adds a rule on primary residences. A Texas homestead caps at 80% combined loan-to-value, so the top tiers never apply there. Texas second homes and investment properties follow the standard tables.

Will the Purchase Lender Accept Borrowed Down Payment Funds?

It depends on the program, and that is the honest answer. Some acquisition lenders accept a documented draw secured by real estate you own. Some cap how much of the down payment can be borrowed. Some treat cash to close and reserves under different rules, so a draw that covers the down payment may not also count toward reserves.

Here is what clears files. Show the line’s closing documents. Show the draw landing in your account. Show the transfer to title. Fewer unexplained deposits means fewer questions.

What derails them: a draw that is mixed with other money, a transfer routed through an account nobody documented, and a plan that assumes the borrowed funds will also satisfy reserves. Ask the acquisition lender before you draw, not after. Lenders in the network vary, and a few are stricter than most.

Also consider the market for a seller. A BiggerPockets discussion notes that cash-like offers can look stronger to sellers, which is part of why investors use equity lines this way.

The DSCR Side: What Rent Covers and What It Doesn’t

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. Lendmire’s complete DSCR loans guide walks through that review in detail.

Typical ranges across the wholesale network:

• Purchase leverage: Most files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700 or better score.
• Coverage: A 1.00 ratio is where select programs start. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage 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 or better score unlocks the strongest leverage tiers.
• Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).
• Reserves: They vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans step up toward 9 months.

The HELOC payment is generally not in the DSCR formula, which divides rent by the new property’s PITIA. A larger down payment can lift the ratio by shrinking the payment. It never removes leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

One experience note from the file level. When a borrower stacks a line on top of a purchase, the DSCR often clears while the real month-to-month margin is thin. The ratio only compares rent to PITIA. Repairs, vacancy, management, utilities, and capital expenses sit outside it. A file can show 1.2x coverage and still lose money after the line payment comes out of the investor’s pocket. Clearing 1.00 is not the same as positive cash flow.

Some DSCR lenders still look at the whole debt picture, so disclose the line up front.

Where the General Rule Breaks

Lines on rentals can vanish. Some lenders don’t write them at all, and availability is lender-specific. Lendmire’s HELOC placements are also limited to its 16 full-service states, which is narrower than the 41-market DSCR footprint. Anyone planning around an investment-property line should have the commitment before they go under contract.

Lenders can freeze or cut lines. The same BiggerPockets discussion says banks have frozen and greatly reduced usable HELOC funds when the market turns. Open the line before you need it, and don’t rely on undrawn capacity to close a contract.

The draw period ends. The CFPB’s HELOC brochure explains that payments can change even if you draw nothing more, that some plans allow interest-only payments during the draw, and that when the draw ends the lender may set a repayment schedule, often over ten or 15 years, or require the whole balance at once. In Lendmire’s network, pricing on the line floats through both the draw and repayment periods and never converts to fixed. The investment structure runs a 5-year draw with a 25-year repayment. On primary homes and second homes, a 3-year draw with a 17-year repayment is also offered, and Tennessee shortens both structures.

Exposure caps. A borrower is limited to three lines in the network, and a borrower with more than 15 financed properties is not eligible.

Property types. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable, are eligible for the HELOC. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible. Manufactured homes, log homes, and barndominiums are also not offered under the network’s DSCR programs.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.

Buy cash, then refinance. Some investors use the draw to buy outright, rehab, and then refinance, paying off the line at that closing. A DSCR cash-out refinance tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. Short-term-rental collateral is tighter: 70% on cash-out. See Lendmire’s page on investment property refinance for the refinance side. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

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.

Does the Deal Still Work If the Rent Stops?

Run it as a stress test, not a pitch. Picture an investor who draws on a primary-home line and buys a duplex at 75% LTV with rent covering PITIA at roughly 1.2x. On paper the loan clears. Now count the other obligations: the first mortgage on the home, the line’s interest, and the duplex’s operating costs. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

Two things happen when one unit sits empty. The ratio on the duplex drops, and the personal payments stay the same. Interest on the drawn balance keeps running, and since at least 75% of the line is drawn at closing, that carry starts on day one.

The practical test is simple. Can you carry the home mortgage, the line, and the rental’s full PITIA out of your own pocket for several months with no rent? If the answer is no, the plan is leveraged tighter than the file shows. BiggerPockets frames the risk bluntly: without a firm exit strategy to repay the line, the investment doesn’t justify risking the roof over your head.

HELOC, Cash-Out, or Savings: A Decision Table

A line fits an investor with equity in a primary home, solid credit, and a short plan to repay it. A cash-out refinance fits a rental with seasoned equity where the investor is willing to reset the loan. Savings fit anyone who doesn’t want a second lien.
