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 | $2,349.63 | $2,749.43 | -$23,988 | -$23,988 |
| Break-even (Year 8) | $2,390.53 | $2,359.72 | $2,865 | $2,958 |
| Year 10 | $2,423.80 | $2,193.82 | $23,595 | $27,599 |
| 30-Year Total | $2,690.01 | $886.14 | $254,178 | $649,394 |
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 $968,404 versus $319,010 for buying, leaving a $254,178 net worth lead for homeowners.
Break-even: by Year 8, buying is ahead by $2,865 while the homeowner's monthly cost drops below renting.
