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 | $2,232.43 | $2,171.02 | $3,685 | $3,685 |
| Year 10 | $2,207.41 | $1,678.20 | $63,505 | $63,505 |
| 20-Year Total | $2,192.06 | $860.35 | $282,382 | $319,612 |
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 $526,095 versus $206,483 for buying, leaving a $282,382 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $3,685 while the homeowner's monthly cost drops below renting.
