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) | $1,167.33 | $1,124.71 | $1,534 | $1,534 |
| Year 5 | $1,189.41 | $969.05 | $12,079 | $13,222 |
| Year 10 | $1,246.38 | $806.20 | $40,923 | $52,821 |
| 30-Year Total | $1,450.92 | $336.50 | $200,403 | $401,192 |
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 $522,333 versus $121,141 for buying, leaving a $200,403 net worth lead for homeowners.
Break-even: by Year 3, buying is ahead by $1,534 while the homeowner's monthly cost drops below renting.
