Listings are a product problem, not a design problem
A real-estate site lives or dies on its listing experience: search that filters by what buyers actually filter by, maps that load fast, galleries that swipe instantly on a phone. Under the hood it is a data problem: every listing needs its own clean URL that can rank, and sold or archived listings must be handled properly (redirects and honest 410s), or Google fills its index with dead pages and starts distrusting the whole site.
