What we assumed / Why this is realistic

Mortgage P&I: Standard amortizing loan formula (fixed-rate).

Property tax & maintenance: These regularly bite - tax is quoted as % of price per year; maintenance uses a 1% rule by default.

Closing costs: Usually 2–5% of price - paid once at closing and included in your upfront cash requirement.

Advice: If your leftover after housing + existing spending + debt + savings target is >= 20% of take-home, you're reasonably safe. 5–20% → house-poor. <0 → can't afford it.
