Import and Export Property Listings in Seconds

Managing large numbers of property listings manually can be time-consuming and inefficient.

Whether you are an estate agent, letting agent, property developer, landlord, or property marketer, our BLM tools allow you to upload your entire property portfolio in a matter of seconds.

No repetitive data entry. No manual copying. No unnecessary administration.

Simply upload your BLM file and your properties can be published instantly.

Bulk Upload Property Listings with Ease

Instead of creating listings one by one, you can import hundreds of properties at once using a single BLM file.

This allows you to:

  • Upload entire property portfolios
  • Migrate listings from other systems
  • Keep property data synchronized
  • Save hours of manual work
  • Reduce human error
  • Publish properties faster

Don't Have a BLM File?

If you need to generate a BLM feed from an existing listing, you can use blmconverter.com.

The converter can generate a compatible BLM file which you can import directly into ListProperty.

What Is a BLM File?

BLM is one of the most widely used property data feed formats in the United Kingdom.

A BLM file contains structured listing information such as references, sale/rent status, property type, prices, addresses, descriptions, EPC ratings, media, brochures, and virtual tours.

Supported Import Formats

  • Standard BLM (`default`) - recommended for most users.
  • Property Hive (`property_hive`) - for Property Hive-compatible workflows.
  • Rightmove (`rightmove`) - Rightmove-style feed layouts.
  • Zoopla (`zoopla`) - Zoopla-compatible BLM structures.
  • OnTheMarket (`onthemarket`) - OTM-style BLM workflows.

Export Public and Private Portfolios

You can export individual listings, full portfolios, public portfolios, private portfolios, client shortlists, and agency collections.

Generate a BLM file instantly and use it with compatible software, websites, or property systems.
