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 | $2,035.55 | $2,411.69 | -$22,568 | -$22,568 |
| Break-even (Year 8) | $1,948.70 | $1,898.40 | $4,829 | $4,829 |
| Year 10 | $1,888.60 | $1,640.66 | $29,752 | $29,752 |
| 15-Year Total | $1,730.56 | $1,050.43 | $122,424 | $122,424 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 15 years, renting totals $311,500 versus $189,077 for buying, leaving a $122,424 net worth lead for homeowners.
Break-even: by Year 8, buying is ahead by $4,829 while the homeowner's monthly cost drops below renting.
