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 | $1,954.34 | $2,093.77 | -$8,366 | -$8,366 |
| Break-even (Year 6) | $1,961.58 | $1,936.45 | $1,810 | $1,810 |
| Year 10 | $1,998.17 | $1,562.16 | $49,416 | $52,321 |
| 25-Year Total | $2,113.84 | $767.14 | $257,564 | $404,013 |
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 $634,153 versus $230,141 for buying, leaving a $257,564 net worth lead for homeowners.
Break-even: by Year 6, buying is ahead by $1,810 while the homeowner's monthly cost drops below renting.
