Make real-time data your competitive advantage!

With HelloData’s API, you can access daily updates on millions of multifamily properties, including rent & availability, concessions, fees, amenities, property manager reviews and more.

Our API is used by many of the largest owners, managers and PropTech companies across the U.S. to understand their markets and build data-driven products.

Use Cases

We are customers of our own API, so we use it to power all our analyses and services. Don’t hesitate to visit our platform to see how we use our data to provide market insights, comparables, pricing recommendations, and more. But you can also build much more by using our API along with your own data and services. Here are some ideas:

  • PowerBI Dashboards: Pull in daily updates on every institutional multifamily property in the country, including unit-level historical rent and concessions data.
  • Deal Sourcing: Identify value-add investment opportunities at scale, or use our data in aggregate to identify properties with specific attributes (e.g. swimming pools, golf simulators, etc.) for business development.
  • Excel Models: Bring detailed market data directly into your Excel models to analyze deals faster.
  • Track Your Competition: Understand your competitor’s pricing strategy, check how often they change their prices, on which days, and by how much. Detect if they use dynamic pricing or revenue management.
  • Computer Vision: Extract room types, amenity data and quality/condition assessments from interior and exterior property photos using our computer vision model.
  • Market Analysis: Track new units hitting the market, analyze trends in rent and leasing velocity, and understand the distributions of pricing and concessions in granular detail.
  • Revenue Management Systems: Use our floorplan comp data to optimize your pricing and maximize your revenue.
  • Chatbots: Power your chatbot with real-time data to answer questions about properties and pricing.

And all of that is doable with only a handful of endpoints and a simple API. Let’s get started!
