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 | $4,715.76 | $5,207.00 | -$29,475 | -$29,475 |
| Break-even (Year 9) | $5,032.34 | $4,960.31 | $6,601 | $7,779 |
| Year 10 | $5,115.81 | $4,917.94 | $19,421 | $23,745 |
| 30-Year Total | $7,233.26 | $4,008.57 | $561,988 | $1,160,888 |
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 $2,603,972 versus $1,443,084 for buying, leaving a $561,988 net worth lead for homeowners.
Break-even: by Year 9, buying is ahead by $6,601 while the homeowner's monthly cost drops below renting.
