How to read this estimate

NOI excludes financing, income taxes and capital replacements. Cash flow includes your capital reserve. No appreciation or tax benefits are assumed.

Downside: scheduled rent and other income fall 10%, vacancy rises 5 percentage points, and fixed expenses remain unchanged.

Verify actual rent rolls, property taxes after sale, insurance quotes, local rules, repairs and vacancy. Rates and costs are editable assumptions, not investment-loan quotes.
