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 | $2,993.95 | $3,345.27 | -$21,079 | -$21,079 |
| Break-even (Year 8) | $3,133.15 | $3,112.12 | $2,019 | $2,019 |
| Year 10 | $3,230.72 | $2,996.21 | $28,142 | $28,142 |
| 20-Year Total | $3,782.69 | $2,434.11 | $286,428 | $323,659 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 20 years, renting totals $907,845 versus $584,186 for buying, leaving a $286,428 net worth lead for homeowners.
Break-even: by Year 8, buying is ahead by $2,019 while the homeowner's monthly cost drops below renting.
