Custom Listing Platforms

We build custom property listing platforms, real estate portals, and marketplaces with fast search, listing management your team controls, and every inquiry sent to the right person.
- Custom property search
- MLS or your own listings
- Leads synced to your CRM
Overview
Property listing platforms built around how people search
Buyers, renters, and investors don’t search the way a database is organized. When a listing platform is slow or clumsy, they leave for someone else’s.
Our real estate listing platform development starts with your users: what they search for, how they compare listings, and when they’re ready to inquire. We then design the search, listing pages, and admin tools around that journey. Listing platforms are a core part of our custom real estate software development work.

Portals and Marketplaces
Real estate portal development and custom property marketplaces
Not every listing platform runs on MLS data. We also build real estate portals and marketplaces for listings you or your users manage.
From commercial space and businesses for sale to multi-user property marketplaces, we plan the data, search, and user roles around your business, then connect everything to your CRM.
What we build
- Property listing platforms for your own inventory
- Real estate portal development with user accounts
- Custom property marketplaces for buyers, sellers, and agents
- Commercial real estate listing platforms
- Roles and permissions for staff, agents, and admins
- Inquiry routing and reporting built in
MLS Website Integration
MLS website integration for listing platforms
When your platform shows MLS listings, the data has to be accurate, current, and compliant.
We build on the RESO Web API and also work with legacy RETS and vendor data feeds. We guide the data licensing application with your MLS, configure the feed once approved, and monitor sync so listings stay current.
What MLS integration covers
- RESO Web API and vendor data feeds
- MLS data licensing guidance
- Display and attribution rules handled
- Scheduled sync with stale-data alerts
- Listing pages built for search engines
- Multiple markets on one platform
Property Management
Property management software and portals
Property managers need more than listings: they need portals for the people behind them.
We build property management software features such as rental applications, tenant portals, maintenance requests, owner reporting, and payment status views, for small landlords and growing management companies alike.

- MLS feed setup and any data or vendor fees
- Depth of custom search, maps, and filters
- Number of user roles and portals
- Listing volume and number of markets
