Home Equity Line of Credit Investment Down Payment

The Quick Read: A home equity line can supply the cash for an investment down payment, but it does not buy the rental. It is a separate loan from the purchase loan, and the purchase lender decides whether borrowed funds are acceptable. The line is underwritten to you, while a DSCR purchase loan is underwritten to the property’s rent.

• A line of credit and a DSCR purchase loan are two approvals, and each has its own rules.
• Across the wholesale network, most DSCR purchases land at 75%-80% LTV, so the down payment is typically 20%-25%.
• On the line itself, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000.
• Borrowed down-payment funds count toward cash to close, not toward reserves.
• Clearing 1.00 coverage on the new loan is not the same as positive cash flow once the line payment is added.

A broker sees this pairing weekly. Equity sits in one property, and the next rental needs a down payment. The structure works when the investor treats it as two obligations on one deal, not one.

What Is a HELOC Down Payment Strategy?

It is a three-step flow: equity in a property you own becomes a credit line, you draw cash from the line, and that cash goes toward the down payment on a separate purchase loan. Nothing about the line changes how the purchase loan is judged.

The line is secured by the property it sits on. A lender can foreclose if the debt is not repaid as agreed. That is true whether the collateral is your residence or a rental.

During the draw period you can generally borrow up to the limit whenever you want, and some plans allow interest-only payments. The federal consumer-finance regulator’s HELOC brochure adds that variable-rate payments can change even if you draw nothing more. So the cost of the strategy is not fixed on the day you draw.

How Big Can the Line Be?

Line size starts with simple arithmetic: appraised value times the lender’s combined-loan-to-value cap, minus what you owe on the property. The federal consumer-finance regulator’s older HELOC booklet walks through this formula, using a $100,000 home, a 75% cap and a $40,000 balance to arrive at a $35,000 line. Treat that as an illustration of the method only.

On this network the caps are set by occupancy:

The investment tier is flat. A 720 score and a 700 score both reach 70%, so a higher score buys eligibility, not leverage. There is no tier above 70% on an investment line. A line above $500,000 is for primary residences only, needs a credit profile of 700 or better (720 on the longer-runway structure), and caps at 75% CLTV with a full appraisal. The 90% ceiling applies only to lines at or below $500,000.

Lenders also look at income, debts and credit when they set the actual limit, so equity alone does not set the number. Debt-to-income runs to a 50% maximum on these lines, with 45% for credit profiles from 600 to 679. Everything here is subject to lender guidelines and full file review.

Which Property Secures the Line?

The choice is between your primary home and an existing rental, and it changes both the room you get and the risk you take. Primary-home lines usually allow more leverage. Rental lines keep the risk on the rental.

Two points matter in practice. First, putting your home behind an investment means a vacancy or repair surprise on the rental can threaten where you live. Benzinga notes that a line on a rental can bring foreclosure risk on that rental and negative cash flow if rent does not cover the payment. Second, the line’s own rules apply. Lines on this network are written to individuals or revocable living trusts, so a rental deeded to an LLC cannot hold the line. That is the sharpest structural difference from a DSCR loan. A property already in an LLC needs a vesting change or a DSCR cash-out instead.

Availability is also narrower than the DSCR footprint. These lines run through select wholesale partners in Lendmire’s 16 full-service states only (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA), while DSCR purchase loans reach 41 markets, including Washington, D.C.

How Does the Purchase Lender Treat Borrowed Funds?

Treatment varies by program, and this is where files get stuck. No agency rule decides it for DSCR loans. Each lender sets its own policy on borrowed down-payment funds, so the answer depends on the lender, not on the line.

Across the wholesale network, the pattern on DSCR purchases looks like this:

• Down payment: borrowed funds from a secured line are commonly accepted toward the down payment on select programs. Some lenders resist unsecured borrowing.
• Reserves: borrowed funds do not count as reserves. An undrawn line does not count either. Reserves must sit in your own accounts and are commonly around 6 months of PITIA, varying by lender, leverage and loan size.
• Documentation: expect a paper trail showing the line, the draw, and the deposit into your account. Large deposits get questions. That is lender-specific, not a rule.
• The near-100% concern: if the down payment and the purchase are both borrowed, the property is effectively fully leveraged. That is why some lenders pull back from it.

The practical move is to ask the purchase lender, in writing, how it treats the borrowed funds before you go under contract. A broker placing the file with a lender that already accepts them avoids a late surprise. Lendmire’s piece Using Home Equity For Down Payment On Investment Property covers the broader options.

Where the Math Gets Tight

The DSCR ratio compares rent to the new loan’s PITIA (principal, interest, taxes, insurance and any HOA dues). The line payment generally sits outside that ratio. But it is a real monthly cost.

Picture an investor whose new fourplex clears 1.2x coverage on the purchase loan. The file looks clean. Then the line payment lands on top, and the real cash flow thins out. Coverage clears while the investor’s pocket runs tight. A BiggerPockets reply on this exact question puts it plainly: the numbers work only if the property can carry both the first mortgage and the line.

Remember what coverage leaves out. Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities and capex all sit outside the calculation. Stack a line payment on top and the margin for error narrows further.

Variable pricing adds a second risk. The CFPB explains that HELOC rates are usually variable and payments can change month to month. This is a short-hold or planned-refinance strategy, not a set-and-forget one.

The Draw-Period Cliff

Investment lines on this network run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing, and pricing floats through both phases and never converts to fixed. Primary residences and second homes can also choose a 3-year draw with a 17-year repayment (Tennessee shortens both structures).

Interest-only payments are qualified on the maximum draw. That means the payment stays modest during the draw, then steps up when principal starts. The CFPB notes that payments are often significantly higher in repayment, and in some cases the whole balance can come due when repayment begins. Build the exit plan before you draw, not at the cliff.

Exit Plans That Work

Three exits come up most:

1. Pay it down from cash flow and savings. Works when the rental carries real margin and the line is modest.

2. Refinance the new rental and retire the line. This is the BRRRR-style exit. After the purchase, a DSCR cash-out refinance on the new property can repay the line. Cash-out typically tops out around 75% LTV on a standard rental (70% on short-term-rental collateral), with about 6 months of seasoning as the common expectation. Lendmire’s page on the cash-out refinance for investment property covers that route.

3. Sell or hold until the line is cleared. Slowest, and riskiest if values move.

Investor commentary on BiggerPockets says the BRRRR version only works if the line can be paid down in a relatively short time. That matches what files show.

Where the General Rule Breaks

Entity-held rentals. If the rental you want to borrow against sits in an LLC, the line cannot be written on it as-is.

Ineligible property types. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use or agricultural-zoned properties are not eligible for the line. On the DSCR side, manufactured homes, log homes and barndominiums are not offered in the network.

Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program, and a borrower with more than 15 financed properties is not eligible.

Credit history. A bankruptcy needs 4 years of seasoning. On investment files, foreclosure history follows a 7-year path, with 4 years for a deed-in-lieu, pre-foreclosure or short sale.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX and WA.

Scaling. Equity runs out. A BiggerPockets investor reports that a line-funded down payment lets them do only one or two deals at a time.

Small draws. Up-front charges can raise the cost of small draws, according to the CFPB booklet.

Does the Down Payment Source Change the DSCR Loan?

It changes what the lender must verify, not what the loan is. Most DSCR purchases run 75%-80% LTV, so the down payment is 20%-25%. Select programs reach 85% LTV with roughly a 700+ score. Credit floors run from 620 in parts of the network, with most programs wanting around 660. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).

A larger down payment lowers the loan amount and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear two tests: enough equity and enough rental coverage.

On coverage, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. For the full picture, the complete DSCR loans guide lays out how these pieces fit.

Is This Right for You?

It tends to fit when:

• You hold real equity beyond what the line would use, and the line stays well inside the 70% investment cap.
• The new rental covers its own loan with room to spare.
• You have reserves in your own accounts, separate from borrowed funds.
• You have a defined exit, such as a refinance or a paydown schedule.

It tends not to fit when the margin is thin, the plan depends on rents rising, your debt-to-income is already stretched, or losing the collateral would be a serious problem. If the file needs borrowed money for the down payment and the reserves, skip it.

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.

Key Terms Defined

CLTV (combined loan-to-value): Every loan secured by the property added together, divided by the property’s value.
