Inspiration

Our inspiration came from an interest in exploring another form of income and helping others do the same. Many people want to invest in real estate but don’t know where to start — whether it’s flipping houses, renting them, or listing them on Airbnb. We wanted to build a platform that connects to real-time housing data and helps users make smarter, more profitable property decisions. The idea was born from the desire to make financial awareness and property investing more accessible to everyone.

What it does

Our platform connects to Rapid’s API to provide users with live housing data. It then analyzes properties to determine the best way to profit — whether that means flipping, renting, or short-term hosting.

When a user searches for a property, the system:

  • Fetches detailed property data such as price history, neighborhood stats, and estimated rental income.
  • Uses a custom algorithm to estimate ROI for flipping, renting, and Airbnb strategies.
  • Provides a simple profitability comparison dashboard.
  • Offers personalized recommendations based on market trends and property type.
  • It’s like having an investment advisor and housing analyst combined into one easy-to-use platform.

How we built it

  • Frontend: Built with React.js and Tailwind CSS for a clean and responsive UI. We used JavaScript to handle dynamic updates and interactive charts.
  • Backend: Developed using Cloudflare, ensuring a secure and scalable connection between the user and the database. Our backend handles user authentication, stores saved properties, and processes profitability calculations.
  • Integration: Connected the Rapid's API for real-time property listings and financial data. We also experimented with predictive modeling to estimate potential profit margins based on local trends and housing history.

Challenges we ran into

  • API limitations: Rapid's API rate limits and changing data structures required us to process data efficiently.
  • ROI calculations: Designing an algorithm that accurately compares profit across multiple strategies (flip, rent, Airbnb) was complex — especially accounting for maintenance and fees.
  • Backend authentication: Setting up Cloudflare Workers API authentication and managing secure data flow took extra configuration.
  • UI synchronization: Ensuring that real-time data updates displayed smoothly without reloading the page required careful React state management.

Accomplishments that we're proud of

  • Built a functional platform that connects Rapid's API real-time Zillow data with investment analysis tools
  • Learned to use Cloudflare for secure and reliable data management
  • Designed a clean and interactive UI that makes complex financial data easy to understand
  • Developed a working algorithm that compares multiple profit strategies
  • Created an MVP that empowers users to make informed property investment decisions
