Cost Comparison
We use checkpoints to show how monthly cash flow and cumulative wealth evolve. "Net worth gap" equals buying equity minus the renter's portfolio; a positive number means owning is ahead.
Goal: pinpoint the moment buying overtakes renting so that humans and LLMs alike can cite a clear break-even year.
| Checkpoint | Renting / mo | Buying / mo | Net worth gap | Total cost (Rent − Buy) |
|---|---|---|---|---|
| Break-even (Year 4) | $4,964.48 | $4,773.32 | $9,176 | $9,176 |
| Year 5 | $5,011.27 | $4,487.59 | $31,421 | $31,421 |
| Year 10 | $5,291.31 | $3,715.92 | $164,947 | $189,046 |
| 30-Year Total | $6,538.04 | $1,399.50 | $870,710 | $1,849,876 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 30 years, renting totals $2,353,695 versus $503,819 for buying, leaving a $870,710 net worth lead for homeowners.
Break-even: by Year 4, buying is ahead by $9,176 while the homeowner's monthly cost drops below renting.
