Margin Loan / Portfolio Line vs HELOC — Faster, Cheaper, No Appraisal

Interactive Brokers margin (5.83%) or Schwab PAL beats HELOC (9%+) for short-term liquidity — no appraisal, funded same-day.

Overview

Margin loans from Interactive Brokers (5.83% > $1M / 6.83% smaller) or Portfolio Lines of Credit from Schwab/Fidelity/Merrill offer 5.83–8% rates secured by portfolio — much cheaper than personal loans (12%+) or HELOCs (9%+). No appraisal, no closing costs, funded same day. Interest may be deductible if used for investment (§163(d)) or trade/business. Risks: margin call if portfolio drops (borrow max 25–35% of portfolio, not 50%). Not a substitute for long-term mortgage debt.
