FAQ

How long does it take to build a real estate app?

A basic listing app takes 3–4 months. A full marketplace with map search, virtual tours, and MLS integration takes 5–7 months. Add 1–2 months if you need AI-powered features like property valuation.

How much does it cost to build an app like Zillow?

A Zillow-equivalent with comprehensive property data, Zestimate-like valuation, agent marketplace, and mortgage tools would cost $300K–$1M+. However, you can build a competitive niche real estate app for $40K–$100K by focusing on a specific market segment.

Do I need MLS integration for a real estate app?

In the US, MLS integration is critical for comprehensive property data. Outside the US, you will need to build relationships with property developers, brokers, and listing aggregators for data feeds. Some markets allow web scraping of public property data.

What is the best tech stack for a real estate app?

React Native or Flutter for mobile, Node.js with PostgreSQL (PostGIS extension) for location queries, Elasticsearch for search, and Mapbox for maps. This stack handles complex geospatial queries efficiently while keeping development costs reasonable.
