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) |
---|---|---|---|---|
Break-even (Year 4) | $2,101.16 | $1,896.71 | $9,814 | $9,814 |
Year 5 | $2,110.30 | $1,751.99 | $21,499 | $21,499 |
Year 10 | $2,169.08 | $1,365.88 | $92,301 | $96,384 |
30-Year Total | $2,328.43 | $317.22 | $422,418 | $724,037 |
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 $838,235 versus $114,198 for buying, leaving a$422,418 net worth lead for homeowners.
Break-even: by Year 4, buying is ahead by $9,814 while the homeowner's monthly cost drops below renting.
