Dynamic Property Trade Website Development

I need a website developed, simulating top-tier real estate platforms like Housiey.com and MagicBricks, that allows dynamic interaction between buyers, sellers, and their corresponding properties. Crucial features of this website are:

- Property Listings: The site should facilitate sellers to list properties easily.
- User Registration/Login: Users must have ability to register and log in.
- Admin and Sellers Panel: A functional portal for admin and sellers to contribute dynamic updates to properties and projects.
- Home Loan Calculator: would like to add finance calculator for the users; advanced calculator for home loan eligibility etc

Critical property and project updates include:

- Availability Status: Sellers and admin can update property availability status.
- Price Change: Instant updates on price changes need to be featured on the website.
- Progress Updates: Buyers should have visual progress updates for ongoing projects.

The website should facilitate advanced search filters for:

- Location-based Search: Users should be allowed to search for properties based on location.
- Price Range Search: A price range slider for easy and efficient property filtering.
- Property Type Search: An elaborate search filter based on the property type.

Ideal candidates for this project are those with prior experience in real estate website development, a keen understanding of dynamic and responsive web design, and proficiency in modern web development technologies.

Must be scalable for future mobile app development.
