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) |
|---|---|---|---|---|
| Break-even (Year 3) | $2,024.44 | $1,786.93 | $8,550 | $8,550 |
| Year 5 | $2,044.46 | $1,422.28 | $37,331 | $37,331 |
| Year 10 | $2,103.70 | $1,042.99 | $118,828 | $127,285 |
| 30-Year Total | $2,210.21 | $79.59 | $476,354 | $767,023 |
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 $795,676 versus $28,653 for buying, leaving a $476,354 net worth lead for homeowners.
Break-even: by Year 3, buying is ahead by $8,550 while the homeowner's monthly cost drops below renting.
