Connect your Apartments.com multifamily contract with RentEngine

If you have a paid Apartments.com (CoStar) contract for multifamily properties, follow these steps to connect it to RentEngine so your listings syndicate from a single source and avoid duplicates or blocks.

When is this required?

Apartments.com requires a paid contract for buildings with 4+ units. If that applies to you, authorize RentEngine as your feed so Apartments.com can publish your listings from RentEngine.

Do not post the same listings through multiple sources. Using RentEngine as your only syndication feed prevents duplicate/blocked posts.

Step 1 — Set up your multifamily properties in RentEngine

Make sure your multifamily properties and floorplans are configured in RentEngine.

Step 2 — Email your Apartments.com representative (CC RentEngine)

Send your Apartments.com rep a brief email and CC ops@rentengine.io

This message must come from you (the contract holder).

CC: ops@rentengine.io

Subject: Apartments.com Feed – RentEngine

Message:

Hi there,

We’d like to apply our paid Apartments.com (CoStar) contract to properties syndicated via the RentEngine feed.

Here are the buildings that need to be connected:

[List the building names here]

Please let us know if anything else is needed to move forward.

Thanks,

[Your Name]

Step 3 — RentEngine replies with technical details

We’ll respond on the same thread with building names, property IDs, and any feed metadata Apartments.com requests. No further action is required from you in this step.

Step 4 — Apartments.com confirms the change

Apartments.com will confirm once the feed is switched. Your listings will then publish from RentEngine and the leads will flow directly into RentEngine.
