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) |
|---|---|---|---|---|
| Break-even (Year 3) | $2,387.15 | $2,344.93 | $1,520 | $1,520 |
| Year 5 | $2,447.08 | $2,079.65 | $22,046 | $22,046 |
| Year 10 | $2,605.94 | $1,788.53 | $95,184 | $98,089 |
| 25-Year Total | $3,171.68 | $1,167.37 | $454,844 | $601,293 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 25 years, renting totals $951,504 versus $350,211 for buying, leaving a $454,844 net worth lead for homeowners.
Break-even: by Year 3, buying is ahead by $1,520 while the homeowner's monthly cost drops below renting.
