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 | $2,042.51 | $1,989.00 | $3,211 | $3,211 |
| Year 10 | $2,103.69 | $1,608.73 | $45,158 | $59,395 |
| 30-Year Total | $2,158.84 | $521.06 | $171,522 | $589,602 |
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 $777,182 versus $187,580 for buying, leaving a $171,522 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $3,211 while the homeowner's monthly cost drops below renting.
