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 | $4,896.15 | $4,817.59 | $4,713 | $4,713 |
| Year 10 | $5,156.10 | $3,880.92 | $128,922 | $153,022 |
| 30-Year Total | $6,261.80 | $1,454.50 | $751,463 | $1,730,629 |
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 $2,254,248 versus $523,619 for buying, leaving a $751,463 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $4,713 while the homeowner's monthly cost drops below renting.
