Flat principal/mo = $320,000 ÷ 360 = $888.89
Flat fee/mo = $391,555.46 ÷ 360 = $1,087.65
Total monthly = $888.89 + $1,087.65 = $1,976.54 (same as conventional)

EquityBoost 2 Parts 4-Phase Design
Phase 1 (Yrs 1–5): fee $1,355.31 + principal $621.23 = $1,976.54 — halfway between conv interest avg and EB flat fee
Phase 2 (Yrs 6–10): fee $1,329.45 + principal $647.09 = $1,976.54 — designed so Yr 6 net yield ≥ 5.15%, growing each year
Phase 3 (Yrs 11–15): fee $1,298.67 + principal $677.87 = $1,976.54 — yield continues to grow
Phase 4 (Yrs 16–30): fee $847.50 + principal $1,129.05 = $1,976.54 — forced reset to amortize remaining $203,228 over 180 months
