Connect your Apartments.com single-family contract with RentEngine

If you have a paid Apartments.com (CoStar) contract for single-family rentals, 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?

When your single-family rentals are covered under an Apartments.com/CoStar advertising contract and you want Apartments.com to publish them via the RentEngine feed.

Important: Do not post the same listings through multiple sources (e.g., PMS/MLS/previous vendor). Multiple sources can cause blocks or “duplicate” declines. Keep RentEngine as your only syndication source.

Step 1 — Email your Apartments.com representative (CC RentEngine)

Send your Apartments.com rep a brief email and CC [alex@rentengine.io]() and [isaac@rentengine.io]().

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

Subject: Single-Family Syndication – RentEngine Feed Authorization

Message:

Hi there,

We have a paid Apartments.com (CoStar) Single-Family contract and would like all rental listings to be syndicated via the RentEngine feed going forward.

Here are a few example properties:

[Insert a few addresses here]

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

Thanks,

[Your Name]

Step 2 — RentEngine replies with technical details

We’ll reply on the same thread with the property IDs (and any additional metadata Apartments.com requests). No further action is required from you in this step.

Step 3 — Apartments.com confirms the change

Apartments.com will confirm once the feed is switched. Your listings will then publish from RentEngine only.

If your rep asks whether to keep any other feeds (e.g., AppFolio, Rentvine, MLS, prior provider), confirm that listings should come from RentEngine only and that other feeds should remain disconnected.
