What it is

Per-unit master record: address, purchase price, current value, mortgage details, rent, property type, and acquisition date — the foundation every other tab builds from
- ⊞

Active lease tracker: lease start/end dates, monthly rent, security deposit, payment status, and tenant contact — know who owes what and when leases expire before they do
- ◉
Cash Flow + Expenses
Per-property income and expense log grouped by IRS Schedule E categories — insurance, repairs, management fees, mortgage interest, property taxes, utilities, depreciation — export-ready for your accountant

Returns Engine
Enter purchase price, rent, expenses, and mortgage; get live cap rate, cash-on-cash ROI, NOI, monthly and annual cash flow, equity, and portfolio ROI rollup that recalculates the moment you change an assumption
Exclusive Feature
Returns Engine is a live cap rate, cash-on-cash ROI, and NOI calculator. Enter any property's purchase price, rent, expenses, and mortgage and it returns cap rate, cash-on-cash return, net operating income, monthly cash flow, annual cash flow, estimated equity, and portfolio-level totals instantly. Change a rent assumption and every number updates in real time. Every Etsy competitor ships a static spreadsheet you fill in by hand — none calculate. Nothing in this market does this in a single offline browser file.
This is built into the fifth tab and is unavailable in any static template, spreadsheet, or Notion template on the market.
