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 | $2,524.58 | $2,848.30 | -$19,423 | -$19,423 |
| Break-even (Year 9) | $2,521.09 | $2,510.21 | $1,174 | $1,174 |
| Year 10 | $2,522.21 | $2,448.68 | $8,824 | $8,824 |
| 30-Year Total | $2,614.53 | $1,217.63 | $290,183 | $502,883 |
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 $941,231 versus $438,348 for buying, leaving a $290,183 net worth lead for homeowners.
Break-even: by Year 9, buying is ahead by $1,174 while the homeowner's monthly cost drops below renting.
