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 | $1,439.90 | $1,636.75 | -$12,954 | -$11,811 |
| Year 10 | $1,541.41 | $1,432.40 | $1,182 | $13,081 |
| 30-Year Total | $2,054.82 | $1,117.00 | $136,824 | $337,613 |
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 $739,734 versus $402,121 for buying, leaving a $136,824 net worth lead for homeowners.
Break-even: by Year 10, buying is ahead by $1,182 while the homeowner's monthly cost drops below renting.
