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 | $2,993.95 | $3,255.94 | -$15,720 | -$15,720 |
| Break-even (Year 7) | $3,085.82 | $3,046.19 | $3,329 | $3,329 |
| Year 10 | $3,230.72 | $2,793.66 | $52,447 | $52,447 |
| 15-Year Total | $3,492.63 | $2,383.95 | $199,562 | $199,562 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 15 years, renting totals $628,674 versus $429,111 for buying, leaving a $199,562 net worth lead for homeowners.
Break-even: by Year 7, buying is ahead by $3,329 while the homeowner's monthly cost drops below renting.
