Before you get a HELOC, understand that your home is the collateral. If you can’t make the payments, you could lose your house. The low rates are attractive, but the risks are real — especially with variable rates during the repayment period.
8-Point HELOC Checklist
| # | Check This | Why It Matters |
|---|---|---|
| 1 | Calculate your available equity | Home value × 80-85% minus mortgage balance |
| 2 | Understand draw vs. repayment periods | Interest-only during draw; P&I during repayment |
| 3 | Check the variable rate terms | How high can the rate go? What index is it tied to? |
| 4 | Compare HELOC vs. home equity loan vs. other options | Fixed rate may be better for large one-time expenses |
| 5 | Determine what you’re using it for | High-value purposes only — not vacations or shopping |
| 6 | Budget for the repayment period payment shock | Monthly payments can double or triple when draw period ends |
| 7 | Check for fees and penalties | Annual fees, early closure fees, inactivity fees |
| 8 | Make sure you can repay even if home values drop | Owing more than your home is worth = underwater |
HELOC vs. Home Equity Loan
| Feature | HELOC | Home Equity Loan |
|---|---|---|
| How funds are disbursed | Revolving credit line — draw as needed | Lump sum |
| Interest rate | Variable (tied to prime rate) | Fixed |
| Monthly payment | Variable (interest-only during draw) | Fixed |
| Draw period | 5-10 years | N/A — receive full amount upfront |
| Repayment period | 10-20 years (P&I) | 5-30 years (P&I) |
| Best for | Ongoing expenses, renovations, emergency fund backup | One-time expense, debt consolidation, specific project |
| Risk level | Higher (variable rate + payment shock) | Lower (predictable payments) |
Equity Calculation
| Your Home | Example |
|---|---|
| Current home value | $400,000 |
| Maximum LTV allowed (80%) | $320,000 |
| Current mortgage balance | -$250,000 |
| Available HELOC amount | $70,000 |
| LTV Limit | Available HELOC ($400K home, $250K owed) |
|---|---|
| 80% | $70,000 |
| 85% | $90,000 |
| 90% | $110,000 |
Payment Shock Example
| Period | Balance | Rate | Monthly Payment |
|---|---|---|---|
| Draw period (years 1-10) | $60,000 | 8.5% | $425 (interest only) |
| Repayment period (years 11-20) | $60,000 | 9.5% | $634 (P&I) |
| Repayment if rates rise | $60,000 | 12% | $860 (P&I) |
Payments can increase 50-100% when the draw period ends and principal repayment begins.
Good and Bad Uses for a HELOC
| Good Uses | Bad Uses |
|---|---|
| Home improvements that add value | Vacations or lifestyle spending |
| Debt consolidation (if disciplined) | Investing in speculative assets |
| Emergency fund backup (not primary) | Funding a business with uncertain income |
| Education expenses (compare vs. student loans) | Buying a car (use an auto loan instead) |
| Bridge financing between home sale and purchase | Daily expenses or recurring bills |
HELOC Fees and Costs
| Fee | Typical Amount | Notes |
|---|---|---|
| Application fee | $0-$500 | Some lenders waive this |
| Appraisal | $300-$600 | Required to confirm home value |
| Annual fee | $0-$100 | Charged whether you use the line or not |
| Early closure fee | $300-$500 | If you close within 2-3 years |
| Inactivity fee | $0-$100/year | Some lenders charge if you don’t use it |
| Transaction fee | Usually $0 | Unlike credit cards, most HELOCs have no per-draw fee |
Risks to Understand
| Risk | What Could Happen |
|---|---|
| Variable rate increases | Prime rate rises → your payments rise with no cap in many cases |
| Payment shock at repayment period | Going from interest-only to P&I dramatically increases payments |
| Home value drops | You could owe more than your home is worth (underwater) |
| Lender freezes the line | Banks can freeze or reduce your HELOC if home values fall |
| Foreclosure | Miss payments and the lender can take your home |
| Tax deduction limits | Interest is only deductible if funds are used for home improvement |
The Bottom Line
A HELOC offers low-rate access to your home equity, but it’s secured by your house. Before you open one, make sure the purpose justifies the risk (home improvements and debt consolidation = reasonable; vacations and discretionary spending = dangerous). Budget for the repayment period payment increase, and don’t borrow the maximum just because it’s available. If you need a predictable payment, a fixed-rate home equity loan is the safer choice.
