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 | $3,305.61 | $3,930.09 | -$37,468 | -$37,468 |
| Year 10 | $3,585.65 | $3,684.41 | -$14,348 | -$11,851 |
| Break-even (Year 12) | $3,706.37 | $3,624.06 | $1,101 | $11,853 |
| 30-Year Total | $5,067.86 | $2,973.74 | $336,551 | $753,885 |
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 $1,824,431 versus $1,070,545 for buying, leaving a $336,551 net worth lead for homeowners.
Break-even: by Year 12, buying is ahead by $1,101 while the homeowner's monthly cost drops below renting.
