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 | $2,278.26 | $2,221.09 | $3,430 | $3,430 |
| Year 10 | $2,310.33 | $1,791.73 | $62,232 | $62,232 |
| 25-Year Total | $2,446.42 | $782.90 | $341,551 | $499,054 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 25 years, renting totals $733,925 versus $234,871 for buying, leaving a $341,551 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $3,430 while the homeowner's monthly cost drops below renting.
