Required inputs
Primary residence dates (for simplified sale tax)
Current mortgage (for amortization)
Note on P&I
We compute monthly principal & interest from balance, rate, and loan end date.
If you want, you can override monthly P&I for cash flow in Optional Assumptions.
Refinance (RENT w/ REFI)
Tax simplification
If time in the home is 2+ years, we assume 0% capital gains tax on sale.
If under 2 years, we apply the cap gains rate to (sale price − cost basis) if provided.
This is a simplified rule-of-thumb, not tax advice.
