🏠 HELOC Educational Guide
🔒 Lock a Portion at Fixed Rate
Many lenders let you convert part of your HELOC balance to a fixed-rate loan. Lock in when rates are favorable to protect yourself from rising variable rates.
📅 Only Draw What You Need
Unlike a home equity loan, you don't pay interest on unused credit. Draw smaller amounts over time to minimize your interest cost.
🏗️ Common Use: Home Improvements
Using HELOC funds for home improvements may keep the interest tax-deductible and can add value back to your collateral. Compare tax, project, and repayment assumptions carefully.
⚠️ Know Your Draw Period End Date
When the draw period ends, you can no longer borrow and payments jump from interest-only to full principal + interest. Plan ahead to avoid payment shock.

Calculate My HELOCFrequently Asked Questions - Heloc
- What is a HELOC?
A HELOC (Home Equity Line of Credit) is a revolving credit line secured by your home. You can draw funds as needed during the draw period (typically 5–10 years), then repay over a set repayment period. Interest is only charged on what you borrow.
- How much can I borrow with a HELOC?
Most lenders allow you to borrow up to 85% of your home's value minus your outstanding mortgage balance. For example, if your home is worth $400,000 and you owe $220,000, your max HELOC would be $120,000 (85% × $400K − $220K).
- What credit score do I need for a HELOC?
Most lenders require a minimum credit score of 620, while scores of 700+ often qualify for stronger rate scenarios. You also generally need at least 15–20% equity in your home and a debt-to-income ratio below 43%.
- What is the difference between a HELOC and a home equity loan?
A HELOC is a revolving line of credit (like a credit card) with a variable rate, while a home equity loan is a lump-sum loan with a fixed rate. HELOCs offer flexibility; home equity loans offer predictable payments.
- Are HELOC interest payments tax-deductible?
HELOC interest may be tax-deductible if you use the funds to buy, build, or substantially improve your home. Interest on HELOC funds used for other purposes (debt consolidation, vacations) is generally not deductible. Consult a tax advisor.
- What is a combined loan-to-value (CLTV) ratio?
CLTV is the total of all loans secured by your home divided by its value. To qualify for a HELOC, most lenders require a CLTV of 85% or less. For example, $220K mortgage + $50K HELOC on a $400K home = 67.5% CLTV — well within limit.
