Definition
A Home Equity Line of Credit (HELOC) is a revolving credit line that allows homeowners to borrow against the equity they've built up in their property. Unlike a traditional loan where you receive a lump sum, a HELOC works more like a credit card—you can draw money as needed up to your approved credit limit, pay it back, and borrow again during the draw period (typically 10 years).
HELOCs are secured by your home, which means your property serves as collateral for the loan. Most lenders allow you to borrow up to 80-85% of your home's current value, minus what you still owe on your mortgage. The interest rate is typically variable, meaning it can fluctuate with market conditions. After the draw period ends, you enter the repayment period (usually 10-20 years) where you can no longer withdraw funds and must pay back the outstanding balance through fixed monthly payments.
How It Applies to HELOCs
For homeowners, a HELOC provides flexible access to their home's equity for major expenses like home renovations, debt consolidation, or emergency funds. During the draw period, you typically only pay interest on the amount you've actually borrowed, not the entire credit line. For example, if you have a $100,000 HELOC but only use $30,000 for a kitchen remodel, you'll only pay interest on the $30,000.
The variable interest rate means your monthly payments can change over time. Many HELOCs start with an introductory rate, then adjust based on the prime rate plus a margin. Homeowners should budget for potential rate increases and understand that during the repayment period, payments will likely increase significantly since you'll be paying both principal and interest on the full outstanding balance.
How It Applies to DSCR Loans
Real estate investors often use HELOCs on their primary residence to fund investment property purchases or improvements. Since DSCR loans focus on the rental property's income rather than personal income, investors might tap their home equity through a HELOC for down payments on rental properties that will be financed with DSCR loans.
For example, an investor might use a $80,000 HELOC to put 20% down on a $400,000 rental property, then finance the remaining $320,000 with a DSCR loan based on the property's rental income. This strategy allows investors to leverage their home equity to acquire income-producing properties without having to qualify based on their personal debt-to-income ratio, which is particularly valuable for investors with multiple properties or those who are self-employed.
Example Calculation
Example: Calculating HELOC Availability
Sarah owns a home worth $500,000 and owes $200,000 on her mortgage. Her lender offers HELOCs up to 85% of home value.
Step 1: Calculate maximum borrowing amount $500,000 × 85% = $425,000
Step 2: Subtract existing mortgage balance $425,000 - $200,000 = $225,000
Sarah's available HELOC amount: $225,000
Monthly Payment Example: If Sarah draws $50,000 at 8.5% interest rate during the draw period: $50,000 × 8.5% ÷ 12 months = $354.17 monthly interest-only payment
During the 15-year repayment period, her payment would increase to approximately $491 per month (principal + interest) assuming the same rate.
