Frequently Asked Questions About Real Estate MLS Portals
Everything you need to know about custom property search engines, board feeds, and cloud infrastructure.
How does Built Digitally achieve sub-second MLS search speeds?
Unlike traditional WordPress plugins that execute heavy SQL queries against external shared database servers on every keystroke, Built Digitally normalizes and caches MLS board data at the edge using Anycast memory stores and vector geo-spatial indexes. Map queries render in under 180ms even with tens of thousands of active listings.
Are these property portals compliant with CREA DDF® and Canadian real estate boards?
Yes. All property portal architectures strictly conform to CREA DDF® data standards and Canadian real estate board rules (TRREB, BCREA, CREB, OREA). Required broker attribution, board disclaimers, listing office credits, and trademark symbols (REALTOR®, MLS®) are automatically formatted and rendered.
What is the difference between an open IDX search and a Virtual Office Website (VOW)?
An open IDX search displays public active property listings permissible without registration. A Virtual Office Website (VOW) allows users to register for an account to access historical sold data, days on market, price drop telemetry, and estimated market values in compliance with board regulations.
Can users draw custom polygon boundaries on the map to search properties?
Yes. Our Mapbox GL geospatial engine allows buyers to draw freehand polygons, radius circles, or neighborhood boundaries directly on the interactive map, instantly filtering listings inside the geographic perimeter without page reloads.
How does the portal capture and route buyer leads to agents?
Portals feature behavioral lead gating, offering preview access before triggering an intelligent registration modal upon viewing a third property, saving a search, or requesting a showing. Inquiries are instantly routed via webhook to your CRM and agent mobile devices with full property context.
Can our brokerage migrate our existing domain and MLS credentials to Built Digitally?
Yes. We manage complete zero-downtime DNS migration, board data license onboarding, and 301 redirect mapping so your existing search engine rankings and backlinks are preserved while upgrading your portal speed and conversion rate.
