A $600,000 home places you in the top 25% of home values nationally. With 28% equity, you can access up to $160,000 — enough to fund a major renovation, consolidate high-rate debt, or serve as a strategic financial reserve.
Credit line varies with your equity percentage. Table assumes no second mortgage. CLTV limits vary by lender.

A $160,000 credit line at the $600,000 tier can fund an entire home addition — garage apartment, in-law suite, or full second story. In top-25% home value markets, these projects often add dollar-for-dollar value or better, especially in supply-constrained metros.
For established homeowners at this equity level, a HELOC at 8.5% is often cheaper than liquidating a taxable investment account (triggering capital gains tax). The math favors borrowing against equity vs selling appreciated assets in many scenarios.
Premium homeowners frequently use HELOCs to fund business ventures or professional investments. A $160,000 line can provide startup capital at rates well below SBA alternatives — but the risk is real: your home secures the debt.
HELOC interest is tax-deductible if proceeds are used to "buy, build, or substantially improve" your home. On $160,000 drawn for renovation at 8.5%, the deduction saves a premium-bracket homeowner ~$2,500–$3,500/year. Keep project receipts.

HELOC Limit = (Home Value × Max LTV%) − Mortgage Balance CLTV = (Mortgage Balance + HELOC Limit) / Home Value Interest-Only Payment = Balance × (APR / 12) P&I Payment = Balance × [r(1+r)ⁿ] / [(1+r)ⁿ−1] where r = APR/12, n = repayment months
