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 | $1,843.23 | $1,834.76 | $508 | $508 |
| Year 10 | $1,876.47 | $1,519.07 | $42,370 | $42,889 |
| 30-Year Total | $1,976.70 | $586.34 | $270,136 | $500,531 |
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 $711,614 versus $211,082 for buying, leaving a $270,136 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $508 while the homeowner's monthly cost drops below renting.
