As a novice developer who understands innovation I would like to add that Zillow has really been a great success and has brought a lot of innovation to the industry. Another interesting company is Opendoor. They offer a "sell now" scheme that allows people to sell their idea quickly and safely. I suggest you read and explore the blog about 20 innovations https://inoxoft.com/blog/20-most-innovative-real-estate-tech-companies-and-startups/ I think my advice will be useful.
