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 | $2,173.69 | $2,084.61 | $5,345 | $5,345 |
| Year 10 | $2,218.60 | $1,694.92 | $61,947 | $62,842 |
| 30-Year Total | $2,365.05 | $568.13 | $352,972 | $646,891 |
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 $851,418 versus $204,528 for buying, leaving a $352,972 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $5,345 while the homeowner's monthly cost drops below renting.
