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 | $1,981.05 | $2,269.29 | -$17,295 | -$17,295 |
| Year 10 | $2,137.48 | $2,049.44 | $3,798 | $10,566 |
| 30-Year Total | $2,950.48 | $1,634.12 | $207,261 | $473,893 |
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 $1,062,174 versus $588,281 for buying, leaving a $207,261 net worth lead for homeowners.
Break-even: by Year 10, buying is ahead by $3,798 while the homeowner's monthly cost drops below renting.
