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 | $2,860.85 | $3,258.86 | -$23,881 | -$23,881 |
| Year 10 | $3,079.04 | $3,012.92 | $7,040 | $7,934 |
| 30-Year Total | $4,202.72 | $2,436.88 | $341,782 | $635,701 |
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 $1,512,978 versus $877,277 for buying, leaving a $341,782 net worth lead for homeowners.
Break-even: by Year 10, buying is ahead by $7,040 while the homeowner's monthly cost drops below renting.
