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 | $1,927.39 | $2,319.00 | -$23,497 | -$23,497 |
| Break-even (Year 9) | $1,960.73 | $1,849.37 | $2,847 | $12,027 |
| Year 10 | $1,968.49 | $1,773.73 | $9,134 | $23,371 |
| 30-Year Total | $1,882.60 | $576.06 | $52,275 | $470,355 |
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 $677,735 versus $207,380 for buying, leaving a $52,275 net worth lead for homeowners.
Break-even: by Year 9, buying is ahead by $2,847 while the homeowner's monthly cost drops below renting.
