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 | $2,993.95 | $3,395.34 | -$24,084 | -$24,084 |
| Break-even (Year 9) | $3,181.44 | $3,152.05 | $3,174 | $3,174 |
| Year 10 | $3,230.72 | $3,109.74 | $14,518 | $14,518 |
| 25-Year Total | $4,104.27 | $2,497.38 | $324,563 | $482,066 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 25 years, renting totals $1,231,281 versus $749,215 for buying, leaving a $324,563 net worth lead for homeowners.
Break-even: by Year 9, buying is ahead by $3,174 while the homeowner's monthly cost drops below renting.
