How to Use a HELOC to Buy Real Estate

A HELOC (Home Equity Line of Credit) can fund a down payment, cover a bridge purchase, or finance investment property — without selling your current home. This guide explains HELOC qualification, draw strategies, tax deductibility rules, and the risks of using home equity to invest in real estate.

A HELOC is one of the most flexible financing tools in real estate — it lets you tap home equity without refinancing your mortgage, move quickly on purchases, and repay on your own timeline. But using debt secured by your primary home for real estate investing requires a clear strategy, a repayment plan, and a risk assessment before drawing a single dollar.

Three ways to use a HELOC in real estate

StrategyUse of HELOC FundsRepayment SourceRisk Level
Down payment supplementCover gap between savings and required down paymentCash flow / savingsMedium
Bridge purchaseBuy new home before selling existingProceeds from existing home saleMedium-High
Cash purchase + refinanceFund full purchase price; refinance outNew rental property mortgageHigh (if DSCR fails)

Step-by-step: using a HELOC for real estate

  1. 1
    Determine your available equity

    Most lenders allow a combined LTV (CLTV) of 85–90% for a HELOC. Formula: (Home Value × 0.85) − Existing Mortgage Balance = Maximum HELOC line. Example: $600,000 home × 85% = $510,000 − $350,000 mortgage = $160,000 maximum HELOC line.

  2. 2
    Apply and get approved before you need the funds

    HELOC approval takes 2–6 weeks. Apply before you find a property to buy — most HELOCs have a 10-year draw period; you do not have to use the line immediately. Having an approved HELOC gives you the flexibility to act quickly on real estate opportunities.

  3. 3
    Define your use case: down payment, bridge purchase, or full cash purchase

    HELOC funds can serve three real estate purchase roles: (1) down payment supplement — fill the gap between savings and required down payment; (2) bridge purchase — buy a new home before selling the existing one; (3) all-cash purchase of a lower-priced property (then refinance out of the HELOC with a traditional mortgage).

  4. 4
    Understand HELOC interest rates and payment structure

    HELOCs are variable-rate products tied to Prime. During the draw period, minimum payments are typically interest-only. This makes them cash-flow efficient but exposes you to rate risk. Model scenarios at Prime + 0.5% and Prime + 1.5% to stress-test affordability.

  5. 5
    Account for tax deductibility of HELOC interest

    HELOC interest is tax-deductible only if the borrowed funds are used to "buy, build, or substantially improve" a qualified residence (primary or second home). Using HELOC funds for investment property interest may be deductible as a business expense — consult a tax professional. Interest used for consumer spending is NOT deductible.

  6. 6
    Plan your repayment before drawing

    Decide how you will repay the HELOC: from rental income, from sale proceeds of the purchased property, or from cash flow after refinancing into a fixed mortgage. Unplanned HELOC debt converts from a tool to a liability. The repayment plan should be written before the first draw.

Common questions

Can I use a HELOC as a down payment to buy another home?

Yes — using a HELOC from your existing home to fund a down payment on a new property is a common strategy. Key considerations: (1) Disclosure: You must disclose the HELOC as a liability on your new mortgage application. The monthly HELOC payment will be included in your DTI calculation; (2) DTI impact: A $150,000 HELOC at a 5% interest rate = $625/month interest-only payment — this reduces your qualifying income; (3) LTV and eligibility: If using HELOC funds as the down payment for an investment property, most lenders require at least 20–25% down and will scrutinize the source of funds; (4) Reserve requirements: After the down payment, you may still need 2–6 months of reserves on the new property; drawing a HELOC for reserves then repaying it the day of closing is NOT acceptable to lenders. See debt-to-income ratio for how this affects qualification. More from the CFPB HELOC explainer.

What is the HELOC bridge purchase strategy?

The bridge purchase uses a HELOC on your current home to buy a new home before the current home sells — avoiding the need to time the sale and purchase simultaneously: (1) Draw your HELOC for the down payment on the new home; (2) Close on the new home; (3) Move in; (4) List and sell the existing home; (5) Use sale proceeds to pay off the HELOC and any bridge balance. Risks: (1) If your existing home takes longer to sell than expected, you carry two sets of housing costs + HELOC interest; (2) If home values decline, you may sell for less than expected — reduce the HELOC payoff cushion; (3) Your lender for the new mortgage will see the HELOC in your DTI and require qualification with both payments. Compare to the formal bridge loan product — bridge loans are shorter-term, more expensive, but may allow higher LTV than a HELOC. See also how to sell and buy at the same time.

Is HELOC interest tax deductible for investment properties?

Tax deductibility depends on use of funds under IRS rules (US) or CRA rules (Canada): US (IRS): HELOC interest is deductible as "home mortgage interest" only if used to buy, build, or substantially improve a qualified residence (primary or second home). Using HELOC to buy an investment property: the interest is NOT deductible as mortgage interest, but may be deductible as investment expense or rental property expense — limits apply. The 2017 Tax Cuts and Jobs Act suspended the deduction for HELOC interest used for purposes other than improving the home through 2025; the status for 2026+ should be verified with a tax advisor. Canada: HELOC interest used to purchase income-producing property (rental) is generally deductible as a business/investment expense under CRA rules — the investment must generate income. Consult a tax professional before drawing for investment purposes. External: IRS Topic 505 — Interest Expense.

Can I use a HELOC to buy an investment property outright?

A HELOC can be used to buy lower-priced investment properties with cash — particularly powerful when you have significant equity and want to move quickly on a deal: Process: (1) Draw your HELOC for the full purchase price + transaction costs; (2) Close on the investment property as a cash buyer (faster, more competitive offer); (3) Refinance the investment property with a traditional rental property mortgage (typically requires 25% equity/LTV ratio); (4) Use the refinance proceeds to repay the HELOC. This is sometimes called a "BRRRR lite" strategy (Buy, Rehab — if needed, Rent, Refinance, Repeat). Requirements: the investment property must have sufficient value and rental income to qualify for the refinance loan (DSCR 1.0+ typically). The HELOC draw during step 1–3 is temporary debt with HELOC interest rates. See cash-out refinance and DSCR for investment property financing details. See CFPB HELOC overview.

What are the risks of using a HELOC to invest in real estate?

Key risks: (1) Your primary home is the collateral: If the investment property underperforms and you cannot repay the HELOC, your primary home could be at risk; (2) Variable rate exposure: HELOC rates are variable — a 2% rate increase on $200,000 = $4,000/year in added interest cost; (3) Forced selling: If the lender reduces or freezes your HELOC (as many did in 2008–2009 when home values fell), you may face sudden repayment demands; (4) Vacancy and rental risk: Investment properties can have vacancies; the HELOC payment continues regardless; (5) DTI cascading effect: High HELOC balance + investment property mortgage creates a complex debt picture that limits future borrowing capacity; (6) Tax complexity: Mixed-use HELOC (some funds for home improvement, some for investment) creates complex deductibility tracking. Mitigant: start with a conservative LTV — draw only 50–60% of available HELOC line to maintain buffer. See LTV management and HELOC freeze risk 2027.

How does a HELOC differ from a cash-out refinance for real estate investing?

Both tap home equity but work differently: (1) HELOC: Line of credit; draw and repay as needed; variable rate; interest-only payments during draw period; no closing costs typically; does not disturb existing first mortgage rate; (2) Cash-out refinance: Replaces existing mortgage with a larger one; lump sum; fixed or variable rate available; 2–4% closing costs; resets your mortgage — risky if existing rate is below current rates. Best use cases: HELOC for flexible, short-term investment capital; cash-out refi for locking in a large fixed amount at a fixed rate for long-term deployment. Example: Using a HELOC to fund a down payment on a rental (temporary), then cash-out refi when investment is stable. In 2027, with mortgage rates elevated, a cash-out refi forces you to refinance your primary mortgage at current rates — often making the HELOC the better choice for those with low-rate existing mortgages.
