KnowYourPropFin — Property Loan Portfolio Modelling for iPhone, iPad & Mac
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
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.
