Using a HELOC for Investment Property Down Payments

How HELOCs Work for Investors

A home equity line of credit (HELOC) allows you to borrow against the equity in your primary residence (or in some cases, an existing investment property). Most lenders allow you to borrow up to 80% to 85% of your home's value, minus your existing mortgage balance. If your home is worth $400,000 and you owe $250,000, you have $150,000 in equity. At an 80% combined loan-to-value (CLTV), your HELOC limit would be $70,000 ($400,000 x 80% = $320,000, minus the $250,000 mortgage).

HELOCs function like a credit card secured by your home. You draw funds as needed, pay interest only on the outstanding balance, and can repay and redraw during the draw period (typically 10 years). After the draw period, the loan enters a repayment phase (typically 15 to 20 years) where you can no longer draw and must pay principal and interest.

Current HELOC rates typically range from 7% to 10%, tied to the prime rate plus a margin. Unlike fixed-rate mortgages, HELOC rates are variable and adjust as the prime rate changes.

The Strategy: HELOC as a Revolving Down Payment Fund

The core strategy is straightforward. Draw from your HELOC to cover the down payment and closing costs on a rental property, then use rental cash flow to repay the HELOC. Once the HELOC is paid down, draw again for the next property.

Here is a concrete example. You have a $70,000 HELOC. You draw $45,000 for a 20% down payment ($37,500) and closing costs ($7,500) on a $187,500 rental property. The property generates $300 per month in net cash flow after all expenses including the investment property mortgage. You also direct $700 per month from your W-2 income toward the HELOC. At $1,000 per month in total repayment, the HELOC is paid off in approximately 4 years, at which point you can repeat the process.

Some investors accelerate this cycle by using the BRRRR strategy: buy with the HELOC, renovate, rent, refinance at the new appraised value (pulling cash out to repay the HELOC), and repeat. If done correctly, the HELOC can be repaid within 6 to 12 months after the refinance, allowing you to acquire multiple properties per year.

Qualification and Setup

Apply for a HELOC before you need it. The approval process takes 2 to 4 weeks, and having an open line of credit gives you the ability to move quickly when a good deal appears.

Lenders evaluate HELOC applications based on your credit score (typically 680 or higher for the best rates), DTI ratio, and home equity. Some lenders are more conservative with HELOCs used for investment purposes and may require a lower CLTV (75% instead of 80%).

HELOCs on investment properties (rather than primary residences) are harder to obtain. Fewer lenders offer them, rates are higher (typically 1% to 2% above primary residence HELOC rates), and maximum CLTV ratios are lower (65% to 70%). If you have multiple properties, prioritize getting a HELOC on your primary residence where terms are most favorable.

Risks and Mitigation

Your home is collateral. This is the most significant risk. If you default on the HELOC, the lender can foreclose on your primary residence. Only use HELOC funds for investments where you have strong confidence in the numbers and adequate reserves to handle unexpected costs.

Variable rate exposure. If the prime rate increases 2%, your HELOC rate increases 2%. On a $50,000 balance, that is $1,000 per year in additional interest. Budget for rate increases and have a plan to pay down the balance if rates spike.

Double leverage risk. When you use a HELOC (debt) to fund the down payment on a property financed with a mortgage (more debt), you are highly leveraged. If property values decline or rental income drops, you are servicing two debts with reduced income. Maintain cash reserves separate from the HELOC to cover at least 6 months of expenses on all properties.

Draw period expiration. When the HELOC draw period ends, the payment increases substantially because you now pay principal and interest. Plan to either pay off the HELOC before the draw period expires or refinance it.

Keep your total HELOC utilization below 50% of the credit limit as a safety margin. This gives you a buffer for unexpected expenses and prevents the HELOC from becoming a financial burden during periods of vacancy or repairs.
