The Real Estate Pond for Real Estate Professionals
Model a property deal from listing to exit — cash flow, scenarios, and portfolio tracking
Property analysis and renovation planning. The Real Estate Pond gives real estate professionals 12 specialised tools in a single HTML file that runs entirely offline.
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.
