Property Details
The stone you throw in — property name, price, currency, type, size, year built, condition, closing costs, and notes. Everything downstream flows from here.
The biggest purchase of your life deserves better than a spreadsheet
The Real Estate Pond is the answer
Mortgage calculations, renovation budgets, neighbourhood comparisons, inspection checklists. Every number affects every other number. Interconnected property models. Change the purchase price and watch mortgage payments, renovation budgets, and ROI projections update instantly.
The Real Estate Pond is a single-file pond with 12 tools that runs entirely in your browser. The Real Estate Pond is a self-contained, browser-based property analysis tool delivered as a single HTML file. It models an entire investment lifecycle across ten interconnected tabs: Property Details, Financing, Rental Income, Operating Costs, Cash Flow, Tax & Depreciation, Scenario Modelling, Portfolio, Returns Dashboard, and Decision Log. Change your purchase price and watch the ripples — mortgage payments, cap rates, cash-on-cash returns, and break-even timelines all recalculate. The Oracle runs three scenarios across appreciation, rent growth, vacancy, and expense inflation. Your financial projections, tenant details, and portfolio data never leave your machine.
