About KnowYourPropFin

KnowYourPropFin is a disciplined, illustration-only workspace for modelling, comparing and documenting complex residential property finance scenarios—without spreadsheet sprawl.

What it helps you explore

• Dual-pass cash-flow modelling: calculates each property and loan independently, then cascades portfolio surplus into offset accounts using your chosen priorities.
• Time-series scenario testing: model overlapping changes to interest rates, vacancy, property growth, inflation and tax assumptions.
• Portfolio-level analysis: compare scenarios against a control and review consolidated metrics such as IRR and return on equity.
• Transparent exports: generate structured workbooks that document key assumptions, inputs and scenario comparisons.
• Protected files: the Escrow Vault separates encrypted exports from their generated passwords, which remain under Apple Keychain and device-authentication controls.

Privacy and user control

Your models are processed and stored on your device and, when enabled, synchronised through your private iCloud account. The developer does not receive, host or process your financial data, export passwords or Keychain-stored secrets. Backup, export, import, selective restore and wipe tools remain under your control.
