A 0.5% difference in mortgage rate on a $350,000 loan saves over $35,000 in interest over 30 years. Always get at least 3 quotes before choosing a lender.
A 600 credit score makes HELOC approval difficult but more achievable than 580. You'll need strong equity (20–25%+), low debt-to-income ratio, and stable income. Expect rates 2–4% higher than borrowers with excellent credit.
At this score range, you'll qualify for some products but with higher rates and stricter terms. Subprime lenders are your primary option.
Expect rates 5–12% above prime borrowers.
Dispute any errors on your credit report — even one removed negative item can push you into the fair range.
Timeline: 6–18 months of positive activity can improve your score significantly.

Based on our analysis of thousands of consumer financial profiles, the most common mistake people make is focusing solely on the interest rate without considering total loan cost, fees, and repayment flexibility. Always compare the APR — not just the rate — and read the fine print on prepayment penalties before signing.
Most major lenders require 620–640 minimum. Some specialized lenders accept 580+. With a 600 score, you have limited but real options, especially if you have 20%+ equity and strong income.
A 600 score will typically result in rates 2–4% higher than a borrower with a 740+ score. On a $50,000 HELOC, that's $1,000–$2,000 more in annual interest. Improving your score before applying can save significant money.
Lenders evaluate: home equity (LTV ratio), debt-to-income ratio (ideally below 43%), income stability and employment history, and payment history on your mortgage. Strong factors in these areas can partially offset a lower credit score.
