What Is a HELOC?

A HELOC (Home Equity Line of Credit) is a flexible, revolving credit line secured by the equity in your home. Think of it like a credit card backed by your home value.

If your home is worth $400,000 and you owe $250,000, you have $150,000 in equity. Most lenders let you borrow 80-90% of that equity, giving you access to $120,000-$135,000 in a HELOC.

How HELOCs Work

Draw Period vs. Repayment Period

HELOCs have two phases:

  • Draw Period (5-10 years): You can borrow and repay as needed. Interest-only payments (no principal). Like a credit card.
  • Repayment Period (10-20 years): Draw access ends. You pay principal + interest monthly. Must pay off the balance.

Example

Year 1-5 (Draw Period): You borrow $50,000 for renovations. Payments: ~$208/month (interest only at 5%). Flexible — pay more to reduce balance, or borrow additional funds as needed.

Year 6-25 (Repayment Period): No more draws. You owe $50,000. Payments jump to ~$500/month (principal + interest). You must pay it off over 20 years.

HELOC Rates and Costs

Interest Rates: HELOCs usually have variable rates tied to the prime rate. Current rates: 7-9% (changes with market).

Costs:

  • Origination fee: 0-1% of credit limit
  • Appraisal fee: $300-500
  • Annual fee: $0-100 (depending on lender)
  • No prepayment penalties

When to Use a HELOC

  • Home renovations: Access funds as work progresses. Pay interest only on what you borrow.
  • Investment property down payment: Borrow cheaply against home equity for rental property acquisition.
  • Emergency fund: Keep credit line open for unexpected expenses (medical, major repairs).
  • Short-term cash needs: Lower rates than credit cards or personal loans.
  • Bridge financing: Borrow while selling another property.

HELOC vs. Home Equity Loan

HELOC: Revolving credit (draw as needed). Variable rate. Flexible.

Home Equity Loan: Fixed loan amount. Fixed rate. Fixed payments. No flexibility.

HELOCs are better for projects where you don't know the final cost. Home equity loans are better if you know exactly how much you need and prefer locked-in rates.

Key Risks

  • Variable rates: Rates can increase, raising your payment significantly.
  • Payment shock: When draw period ends, payments can jump 2-3x.
  • Home equity risk: If home value drops, lender may freeze your credit line.
  • Foreclosure risk: If you can't pay, lender can foreclose on your home.
  • Interest rate environment: Rising rates = higher borrowing costs.

FAQ

Can I use a HELOC for investment property?

Yes. Many investors use HELOCs to fund down payments on rental properties. Since rates are lower than investment property loans, you save on financing costs.

What credit score do I need?

Most lenders require 700+. Some go lower (650+) with higher rates.

What if my home value drops?

Lender can reduce or freeze your credit line. Your payments stay the same, but you can't borrow more.

Can rates lock in?

Some lenders offer rate locks during draw period. Typical cost: 0.25-0.5% higher rate for fixed option.
