Getting a HELOC

A HELOC is a revolving line of credit secured by your home's equity. It works like a credit card: you have a credit limit, can borrow as needed during the draw period, repay, and borrow again.

38 steps across 12 sections

1. Draw Period (Typically 5-10 Years)

  • Borrow up to your credit limit as needed
  • Most lenders require interest-only minimum payments during this phase
  • Can repay and re-borrow repeatedly (revolving credit)
  • Variable interest rate adjusts with the prime rate
  • Some HELOCs allow you to lock portions into a fixed rate during draw period

2. Repayment Period (Typically 10-20 Years)

  • Can no longer draw new funds
  • Begin paying principal plus interest
  • Monthly payments increase significantly (payment shock is a real risk)
  • Rate continues to be variable unless you locked a fixed-rate option

3. Equity

  • Most lenders require at least 15-20% equity remaining after the HELOC
  • Maximum combined loan-to-value (CLTV): typically 80-85%
  • Calculation: (Mortgage balance + HELOC amount) / Home appraised value must be less than or equal to 80-85%

4. Debt-to-Income Ratio (DTI)

  • Maximum: 43-50% (varies by lender)
  • Includes all monthly debt payments divided by gross monthly income

5. Income and Employment

  • Stable, verifiable income required
  • W-2 employees, self-employed (2 years tax returns), and retirees with sufficient income all qualify

6. Example Calculation

  • Home value: $400,000
  • Current mortgage balance: $250,000
  • Maximum CLTV: 80%
  • Maximum total borrowing: $400,000 x 80% = $320,000
  • Available HELOC: $320,000 - $250,000 = $70,000

7. Factors That Increase Your Limit

  • Higher home appraisal value
  • Lower mortgage balance
  • Excellent credit score (some lenders go to 85-90% CLTV)
  • Strong income and low DTI

8. Current Rules (2026)

  • HELOC interest is tax-deductible only if the funds are used to "buy, build, or substantially improve" the home securing the HELOC
  • Combined mortgage + HELOC debt limit for deduction: $750,000 (married filing jointly) or $375,000 (single)
  • Not deductible: HELOC funds used for debt consolidation, tuition, vacations, or other non-home purposes
  • Keep records of how HELOC funds are spent to substantiate the deduction

9. Payment Shock

  • When the draw period ends and repayment begins, monthly payments can double or more
  • Plan for this transition; do not assume you will refinance before repayment starts

10. Variable Rate Risk

  • If the Fed raises rates, your payment increases immediately
  • Rate caps exist but may allow significant increases (e.g., lifetime cap of 18%)
  • Consider a HELOC with a fixed-rate lock option

11. Foreclosure Risk

  • Your home is collateral; missing payments can lead to foreclosure
  • A HELOC is a second lien, but the lender can still foreclose

12. Market Risk

  • If home values decline, you could owe more than the home is worth
  • Lenders can freeze or reduce your HELOC limit if your home value drops
