Monthly investment amount
Each month, whoever's housing cost is lower invests the difference. If buying is more expensive (typical early on), the renter invests the gap. Once rent eventually exceeds the mortgage payment, the buyer invests their surplus. Both households spend the same total monthly outlay.
