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 | $2,679.76 | $2,596.53 | $4,994 | $4,994 |
| Year 10 | $2,861.87 | $2,360.99 | $51,648 | $60,106 |
| 30-Year Total | $3,774.60 | $1,948.34 | $366,784 | $657,453 |
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 $1,358,855 versus $701,402 for buying, leaving a $366,784 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $4,994 while the homeowner's monthly cost drops below renting.
