KnowYourPropFin

KnowYourPropFin replaces spreadsheet sprawl with one structured, illustration-only workspace for single or multi-loan property portfolios. A dual-pass engine first calculates each property's isolated cash flow, tax schedule and amortisation, then runs a priority waterfall that cascades your global surplus into offset accounts by your exact rankings. Inject overlapping time-series shocks — rate changes, capital-gains tax, vacancy, growth, inflation — with precise start months and durations, and control whether loans re-amortise at the start, end, or both. Read true portfolio mathematics (IRR, ROE) across a single consolidated cash-flow stream. Includes a broker remuneration dashboard (upfront/ongoing commissions with portfolio attrition), all-scenario spreadsheet export with assumption lineage, and an AES-256 Escrow Vault that doubles as a convenient, secure password store. Local-first: your data stays on your device and private iCloud — the developer never receives it. Free to use in full. Pay only to keep more than two saved profiles/scenarios at once. Buy once, use everywhere (Universal Purchase) — and your work syncs across devices via private iCloud, so you can pick up the same analysis on iPhone, iPad or Mac, wherever you are. Illustration and education only — not financial advice.
