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 | $2,398.74 | $2,840.17 | -$26,485 | -$26,485 |
| Year 10 | $2,574.91 | $2,606.47 | -$4,306 | -$3,788 |
| Break-even (Year 11) | $2,612.17 | $2,578.58 | $2,534 | $4,434 |
| 30-Year Total | $3,473.93 | $2,092.34 | $266,978 | $497,373 |
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 $1,250,615 versus $753,242 for buying, leaving a $266,978 net worth lead for homeowners.
Break-even: by Year 11, buying is ahead by $2,534 while the homeowner's monthly cost drops below renting.
