Expert Takeaways
Target Income Baseline: Maintain at least $248.3M/mo in household net income (monthly payment $99.3M/mo) to keep your DTI safely below 36%–43%.
Emergency Liquidity Reserve: Keep at least $397.2M (equal to 3–6 months of debt payments) in liquid reserves to hedge against unexpected income shocks.
Interest Rate Shock Buffer: Stress-test your budget for a 1.5%–2% rate increase post-reset, which adds approximately $8.33M/mo to your obligation.
Optimal Prepayment Window: Prepayment penalties typically phase down to zero after 3 to 5 years; target this window for major principal reductions or refinancing.
Accelerated Principal Strategy: Applying an extra $149M toward principal annually directly shrinks your amortization schedule and saves thousands in lifetime interest.
