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 | $3,149.69 | $3,593.69 | -$26,640 | -$26,640 |
| Year 10 | $3,407.61 | $3,346.82 | $3,292 | $7,295 |
| 30-Year Total | $4,760.33 | $2,699.89 | $346,541 | $741,757 |
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 $1,713,717 versus $971,960 for buying, leaving a $346,541 net worth lead for homeowners.
Break-even: by Year 10, buying is ahead by $3,292 while the homeowner's monthly cost drops below renting.
