YieldFrame is a local, browser-based property investment analyser for organising your own purchase, finance, rent, vacancy, income and operating-expense assumptions.

Choose a Financed or All-cash purchase method, add your own custom income, expense and acquisition-cost line items, and review a Lower/Base/Higher sensitivity table alongside the primary results. It calculates estimated NOI, cap rate, cash flow, ROI, cash-on-cash return, DSCR, LTV and break-even occupancy from the figures you enter.

Supplied as a single HTML calculator with a start guide, detailed user guide, licence, disclaimer and support/refund information. No installation or account required — it runs locally in your browser and makes no external network requests.

YieldFrame is an analytical and educational tool, not financial, investment, tax or legal advice. It does not recommend buying, selling, holding or financing any property.
