Why Separate Cash Flow from Real Returns?

💰 Cash Flow = Can You Afford It Monthly

Cash flow counts all monthly outflows (full mortgage payment), because that money actually leaves your account. Negative cash flow = you're topping up the mortgage each month — unsustainable long-term.

📈 Real Return = Is It a Good Investment

Principal repayment isn't an expense — it's saving (it builds your equity). Only interest + fees are real costs. ROI = Net Real Return ÷ Total Cash Invested.

🏠 Impact of Years Already Paid

The longer you've paid, the less principal remains → lower interest costs → higher real return. But monthly cash flow stays the same (fixed payment), so the early years are the tightest.

⚠️ Common Misconception

Many think "rent covers the mortgage = good return." But most of the payment is principal (especially early years when interest is heavy). Real return can be lower than a fixed deposit.
