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) |
|---|---|---|---|---|
| Year 5 | $2,972.71 | $3,163.25 | -$11,432 | -$11,432 |
| Break-even (Year 8) | $3,110.92 | $2,994.58 | $5,908 | $11,169 |
| Year 10 | $3,207.79 | $2,926.74 | $19,490 | $33,727 |
| 30-Year Total | $4,429.49 | $2,389.81 | $316,206 | $734,286 |
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 $1,594,616 versus $860,330 for buying, leaving a $316,206 net worth lead for homeowners.
Break-even: by Year 8, buying is ahead by $5,908 while the homeowner's monthly cost drops below renting.
