The actual cost of building an app depends on a lot of factors like level of complexity, features and functionalities, timeframe of development, etc. Generally, a basic real estate app with core features like property search, listings, and contact forms can cost anywhere from $25,000 to $50,000 to develop. More complex apps with features such as VR tours, integrated payment processing, and AI-powered search can cost upwards of $100,000.
