A live rental-property analysis platform has been created to assist real estate investors and agents in evaluating property cash flows and determining optimal purchase prices. Users can input a property address or listing link, adjust financial assumptions, and navigate through an underwriting workflow. Key features include calculations for cash flow, cap rate, cash-on-cash return, and debt-service coverage. The platform provides a Target-based Offer Ceiling to aid in deciding a suitable purchase price, along with options to edit assumptions and documentation of calculation methods. It offers downside stress testing and long-term financial projections for properties. Advanced features consist of deal saving, comparisons, report generation, acquisition workflow tools, and subscription plans for investors and agents. The platform currently has one paying subscriber and receives several hundred monthly visitors. It is in the early stages of development, with customer acquisition being a key focus for growth. Total hosting and data-service costs amount to $119 monthly, segmented into distinct service providers, excluding additional operating expenses. The sale of the platform includes ownership of the domain, application source code, branding, design assets, and related website content. There is potential for a new owner who could be a software operator, real estate educator, or agency to expand its distribution, improve user conversion rates, and establish a steady customer base. This opportunity is targeted toward existing audiences of investors and agents looking for a comprehensive real estate investment analysis tool.
