Notes on assumptions
- Mortgage payment uses a standard amortization formula (principal + interest only).
- Taxes and insurance are converted from annual to monthly.
- Maintenance reserve is a planning bucket to reduce “big surprise” years.
- Condo/HOA fees can be a major affordability driver and often rise over time.
