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 | $2,534.03 | $2,774.58 | -$14,433 | -$14,433 |
| Break-even (Year 8) | $2,536.69 | $2,502.70 | $3,264 | $3,264 |
| Year 10 | $2,542.78 | $2,373.94 | $20,262 | $20,262 |
| 30-Year Total | $2,700.20 | $1,135.35 | $346,596 | $563,349 |
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 $972,074 versus $408,725 for buying, leaving a $346,596 net worth lead for homeowners.
Break-even: by Year 8, buying is ahead by $3,264 while the homeowner's monthly cost drops below renting.
