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 | $2,485.26 | $3,085.83 | -$36,034 | -$36,034 |
| Year 10 | $2,561.76 | $2,531.41 | $1,145 | $3,643 |
| 30-Year Total | $2,889.21 | $1,159.99 | $205,185 | $622,520 |
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 $1,040,116 versus $417,596 for buying, leaving a $205,185 net worth lead for homeowners.
Break-even: by Year 10, buying is ahead by $1,145 while the homeowner's monthly cost drops below renting.
