Real estate web development revolves around property search, lead capture, and agent tools. The website must integrate with MLS data, provide a search experience that keeps buyers engaged, and funnel inquiries into CRM systems that help agents close deals.
Core Features to Build

- Search interface — location, price range, bedrooms, bathrooms, property type
- Map search — draw-on-map, pin clusters, neighborhood boundaries
- Saved searches — email alerts when new listings match criteria
- Listing detail pages — photos, virtual tours, floor plans, disclosures
- Comparable sales — recently sold properties nearby
- School information — district ratings, proximity data
- Market data — neighborhood statistics, price trends, days on market
- Mortgage calculator — monthly payment estimation on listing pages
