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 | $2,464.75 | $2,419.43 | $2,719 | $2,719 |
| Year 10 | $2,559.00 | $2,028.82 | $59,619 | $63,623 |
| 30-Year Total | $2,966.25 | $831.14 | $373,425 | $768,641 |
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 $1,067,851 versus $299,210 for buying, leaving a $373,425 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $2,719 while the homeowner's monthly cost drops below renting.
