HELOC as Down Payment

A HELOC (home equity line of credit) is a revolving credit line secured by the equity in your primary residence. Many real estate investors use HELOCs to fund down payments on investment properties, converting home equity into acquisition capital. This strategy accelerates portfolio growth but leverages your primary residence, creating risk if markets decline or you can't service the HELOC payments.

Key takeaways

• A HELOC is a revolving credit line (like a credit card) secured by your home's equity
• You draw capital only when needed, paying interest only on the amount borrowed
• HELOC rates are typically 1–2% below mortgage rates and reset annually or quarterly
• Using HELOC to fund investment property down payments is common but leverages your primary residence
• HELOCs are useful for rapid scaling but risky if rental income declines or personal income is unstable

What is a HELOC

Your home's equity is the difference between its value and your mortgage balance. If your home is worth $500,000 and you owe $300,000, you have $200,000 in equity.

A HELOC lets you borrow against that equity, creating a revolving credit line. You can draw $50,000, pay it back, and draw again. You pay interest only on the amount outstanding.

Example:

• Home value: $500,000
• Mortgage balance: $300,000
• Equity: $200,000
• HELOC established: $150,000 (75% of equity)
• You draw $75,000 for an investment property down payment
• Monthly interest cost: $75,000 × 7% ÷ 12 = $438/month
• As you pay down the investment property's mortgage, you pay off the HELOC balance
• Once HELOC is paid to $0, you can redraw the full $150,000

HELOCs are typically set up with a "draw period" (10 years, during which you can withdraw) and a "repayment period" (10 years, during which you can no longer draw and must pay down the principal).

HELOC rates and terms

HELOC rates are variable, typically set at the prime rate plus a margin. As of May 2026:

• Prime rate: approximately 5.5%
• HELOC margin: 1.5–2.5% above prime
• HELOC rate: 7.0–8.0% total

HELOCs are typically 1–2% cheaper than mortgage rates in the same market because:

• They're secured by your primary residence (lower risk to lender)
• They're shorter-term (reset annually or every few years)
• There's an existing relationship (you already have a mortgage with the lender)

HELOC rates reset periodically (monthly, quarterly, or annually), so if prime rates rise, your HELOC rate rises. This is different from a fixed-rate mortgage, which locks the rate for 30 years.

HELOC terms typically include:

• Draw period: 5–10 years (you can draw capital)
• Repayment period: 10 years (you must repay, cannot draw)
• Total duration: 15–20 years
• Interest-only option: During draw period, you may pay interest only
• Full amortization: During repayment period, you pay principal + interest

Using HELOC to fund investment property down payments

The common strategy: use your home's equity to fund down payments on rental properties, effectively leveraging your primary residence to scale real estate faster.

Example: Building a portfolio with HELOC

Year 1:

• Primary home value: $500,000, mortgage $300,000 remaining
• Equity: $200,000
• Establish $150,000 HELOC (75% of equity)
• Investment property 1: $300,000 purchase, 20% down = $60,000 needed
• Draw $60,000 from HELOC, close on property 1
• Mortgage: $240,000, interest = 7.25%, monthly payment = $1,593
• Rental income: $2,200/month
• HELOC interest cost: $60,000 × 7% ÷ 12 = $350/month
• Net monthly: $2,200 rent − $1,593 mortgage − $350 HELOC = $257 positive cash flow

Year 2:

• Property 1 is cash-flowing
• You've paid down HELOC by $5,000 (from positive cash flow)
• HELOC available: $155,000
• Investment property 2: $250,000 purchase, 20% down = $50,000 needed
• Draw $50,000 from HELOC, close on property 2
• Now owe: $300,000 (primary mortgage) + $105,000 (HELOC) + $250,000 (property 2 mortgage) = $655,000 total debt

Year 3–5:

• Properties are cash-flowing
• Both rental incomes are paying down debt
• Over 5 years, you've acquired 5–6 properties funded by HELOC draws
• HELOC is paid down significantly or refinanced into a longer-term loan

The power: without the HELOC, you'd need to save capital between acquisitions (taking 2–3 years to acquire each property). With the HELOC, you can acquire 1–2 properties per year if you have sufficient cash flow to carry them.

Advantages of HELOC-funded acquisition

Speed: You can acquire multiple properties quickly, compressing a 10-year plan into 3–4 years.

Lower interest rate: HELOC rates are cheaper than hard money (10–18%) or portfolio loans (8–9%), and closer to conventional mortgage rates (7–7.5%).

Flexibility: You redraw as needed. Once you've paid down the HELOC, the capital is available again.

Tax deduction: Interest on HELOCs used for investment property acquisition is deductible (subject to the $750,000 cap on home equity debt for tax purposes).

Primary residence remains owner-occupied: You're not financing your primary residence as investment (which changes terms and rates); you're borrowing against it for another purpose.

Risks and disadvantages of HELOC-funded acquisition

Your home is collateral: If you can't pay the HELOC, the lender can foreclose on your primary residence. This is the critical risk that separates HELOC borrowing from other leverage.

Variable interest rate: If prime rates rise, your HELOC rate rises. A $100,000 HELOC at 7% costs $7,000/year. At 8.5%, it costs $8,500/year—a $1,500 increase. If your rental cash flow is tight, a 1.5% rate rise forces you to cut cash or default.

Repayment period shock: After 10 years of drawing and interest-only payments, the HELOC enters repayment. Suddenly you must pay principal + interest, not just interest. A $100,000 balance at 8% over 10 years requires $1,213/month instead of $667/month. If your rentals cash flow at $500/month positive, the jump is unmanageable.

Over-leveraging: HELOC velocity is seductive. It's easy to acquire 10 properties in 5 years, each cash flowing at $100–300/month. But 10 × $200 = $2,000 positive monthly cash flow. Now:

• HELOC balance: $150,000 at 8% = $1,000/month interest
• Primary mortgage payment: $1,500/month
• Total housing cost: $2,500/month
• Rental cash flow: $2,000/month
• Deficit: $500/month

You're now paying out of pocket every month. This is viable if personal income covers it, but it's fragile. One vacant property, one major repair, one economic downturn, and you're underwater.

Recourse liability: If a rental property goes underwater (owe more than it's worth) and you eventually default, the lender may pursue a judgment against you personally. Using HELOC leverage on multiple properties compounds that risk.

Forced refinance risk: If your credit score drops or your income declines, your primary lender may not renew your HELOC. They may force you to pay down the balance or refinance into a fixed-rate home equity loan (higher rate, less flexible).

When HELOC is appropriate

HELOC-funded acquisition is appropriate when:

• You have strong personal income (W-2 job or stable business) separate from rental income
• Your rental properties are cash-flowing at 25%+ of debt service (rental income is 125%+ of debt service, providing a cushion)
• You have 6–12 months of expenses in reserves (primary housing + HELOC + living expenses)
• You understand that your primary residence is collateral and you're comfortable with that risk
• You plan to stabilize or pay down the HELOC within 10 years (before repayment period shock)

HELOC is dangerous when:

• Your personal income is unstable or declining (you're self-employed and uncertain)
• Your rental cash flows are thin (100–110% of debt service, leaving little cushion)
• You have no emergency reserves
• You're using HELOC to fund a rapidly growing portfolio (5+ properties in 2 years) without a clear payoff plan

Alternative to HELOC: Home equity loan

A home equity loan is similar to a HELOC but not identical:

• HELOC: Revolving credit line, variable rate, interest-only during draw period, flexible timing
• Home equity loan: Fixed lump sum, fixed rate, amortizing payments, one-time draw

A home equity loan might be preferable if you want:

• Rate certainty (fixed rate locks in the cost)
• Predictable monthly payments (fully amortizing from day 1)
• No draw period concerns (you get the capital, it's locked)

Home equity loans typically cost 0.25–0.5% more than HELOCs (the bank is giving you less flexibility). If a HELOC is 7.5%, a home equity loan might be 8.0%. For a $100,000 loan, that's $500/year more cost.

Strategic payoff of HELOC debt

If you use a HELOC to acquire properties, you need a payoff plan:

Plan 1: Rental income repays HELOC

• Rental income from properties 1–5 is directed to HELOC paydown
• Properties are cash-flowing at $1,500–2,000/month combined
• In 5–7 years, HELOC is paid to $0
• Then rental income is fully available for next acquisition or personal use

This plan requires disciplined cash flow management: the income must go to debt, not distributions.

Plan 2: Refinance into long-term debt

• After 3–5 years of HELOC draws, the HELOC balance is $150,000
• Refinance the HELOC into a fixed-rate home equity loan (amortizes over 10–15 years at 7.5% fixed)
• Now you have predictable payments ($1,200–1,500/month) and rate certainty
• This avoids the "repayment period shock" where interest-only becomes fully amortizing

Plan 2 is common because it locks in a rate before the repayment period forces amortization.

Plan 3: Sell a property or two, pay down HELOC

• After acquiring 5–6 properties, you've built appreciation and equity
• Sell one property that's appreciated significantly
• Use net proceeds (after paying off the property's mortgage) to pay down HELOC
• Frees up HELOC capacity for next acquisition

Plan 3 is useful if you're ahead on appreciation and want to stop leveraging your primary residence.

Documentation and lender requirements

Using a HELOC to fund investment property acquisitions requires lender approval. Most HELOC applications ask: "What is the purpose of this credit line?" You can honestly answer "real estate investment" or "investment property down payments."

Lenders typically allow this use. However:

• If you use HELOC funds for investment, make sure the interest is deductible (it is, subject to the $750,000 home equity debt cap)
• Don't commingle HELOC funds with personal spending; keep accounting separate
• Some lenders restrict use to home improvement; verify with your lender

If your HELOC lender later claims you violated terms by using funds for investment, disputes can arise. Rare but possible. Use a lender you trust and confirm in writing that investment use is allowed.

A HELOC borrows against your primary home's equity; a cash-out refinance does something similar but through your mortgage. Instead of creating a separate HELOC, you refinance your existing mortgage to a higher amount and pocket the difference.
