The Complete Guide to Home Equity & Second Mortgages
American homeowners hold over $32 trillion in tappable home equity — the largest it has ever been. This guide covers everything about accessing that equity wisely: HELOCs, home equity loans, cash-out refinancing, and the critical decision of which option costs you the least.
How Much Home Equity Do You Have?
Your home equity is the difference between your home’s current market value and what you still owe on your mortgage. As your home appreciates and you pay down your mortgage, equity grows. Most lenders let you borrow up to 80–90% of your home’s value minus your mortgage balance.
Formula: (Home Value × Max CLTV%) − Mortgage Balance = Maximum you can borrow
Example: $600,000 home × 85% CLTV = $510,000 − $350,000 mortgage = $160,000 available to borrow
The 3 Ways to Access Home Equity
| Method | Rate (May 2026) | How you receive funds | Impact on first mortgage | Best when |
|---|---|---|---|---|
| HELOC | 7.21% variable | Revolving line — draw as needed over 10 years | None — stays separate | Flexible, ongoing needs; comfortable with variable rate |
| Home Equity Loan | 7.36% fixed | Lump sum at closing | None — stays separate | Known, one-time expense; want payment certainty |
| Cash-Out Refinance | 6.70% (but on full balance) | Lump sum; replaces first mortgage | Replaces entirely — resets at today’s rate | Your existing rate is 6%+ and you also want to change first mortgage terms |
Deep Dive: HELOC
A HELOC is a revolving credit line at a variable rate — think of it as a credit card secured by your home at a fraction of the interest rate. You borrow what you need during the 10-year draw period, then repay over 20 years.
Current national average: 7.21% APR (Curinos, May 2026). Rates are tied to the prime rate (currently 6.75%) plus a lender margin. When the Fed cuts rates, your HELOC rate falls automatically within 1–2 billing cycles.
Deep Dive: Home Equity Loan
A home equity loan gives you a fixed-rate lump sum — your rate and payment are locked at closing and never change, regardless of what the Fed does. This is the choice for borrowers who want certainty over flexibility.
Current national average: 7.36% APR fixed (Curinos, May 2026). On a $75,000 loan over 10 years, that’s $871/month.
The Decision Tool: HELOC vs Home Equity Loan vs Cash-Out Refi
The right choice depends primarily on three things: your existing mortgage rate, how much you need, and how certain you are about the amount. Use these tools to model your exact situation:
How HELOC Rate Risk Works — The 2022–2023 Lesson
Between March 2022 and July 2023, the Fed raised rates by 5.25%. HELOC rates went from ~4% to ~9%. A borrower with $100,000 outstanding saw their interest-only payment go from $333/month to $750/month — a 125% increase in 16 months. A fixed home equity loan from before those hikes would have kept the same payment throughout.
With the current prime rate at 6.75% and the Fed potentially cutting further in 2026, the rate direction for HELOCs is uncertain. If you need payment certainty, the home equity loan is the safer product even though today’s starting rate is slightly higher.
What Can You Use Home Equity For?
| Use | Interest tax deductible? | Better product | Notes |
|---|---|---|---|
| Home renovation | Yes — if substantially improves the home | HELOC (phase draws) | Most common use; preserves flexibility as costs emerge |
| Debt consolidation | No | Home equity loan (fixed) | Lock in rate; risk is converting unsecured debt to secured (your home) |
| College tuition | No | Either | Often cheaper than parent PLUS loans; HELOC gives flexibility |
| Emergency fund access | Depends on use | HELOC | Set up the line; pay $0 if you never draw. Best low-cost safety net. |
| Investment property DP | No (on HELOC) | Home equity loan | Fixed rate provides predictable cash flow modeling |
| Business investment | No | Either | High risk — your home is collateral for a business bet |
