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 | $6,329.13 | $6,506.10 | -$10,618 | -$10,618 |
| Break-even (Year 6) | $6,435.37 | $6,417.29 | $1,302 | $1,302 |
| Year 10 | $6,884.55 | $6,186.93 | $59,616 | $83,715 |
| 30-Year Total | $9,851.41 | $5,082.00 | $737,825 | $1,716,990 |
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 $3,546,508 versus $1,829,518 for buying, leaving a $737,825 net worth lead for homeowners.
Break-even: by Year 6, buying is ahead by $1,302 while the homeowner's monthly cost drops below renting.
