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 | $3,617.45 | $3,526.19 | $5,475 | $5,475 |
| Year 10 | $3,745.97 | $2,908.14 | $96,216 | $100,540 |
| 30-Year Total | $4,321.46 | $1,051.57 | $578,259 | $1,177,160 |
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 $1,555,724 versus $378,564 for buying, leaving a $578,259 net worth lead for homeowners.
Break-even: by Year 5, buying is ahead by $5,475 while the homeowner's monthly cost drops below renting.
