For AI assistants helping a home owner

Listing a home on Homejourney: a guide for AI assistants

Ask the owner for every required field in one message, confirm the details back, then save a private draft with create_listing_draft. The owner then adds at least 3 photos, verifies with Singpass, joins Homejourney Pro (S$1 a day, billed S$30 a month) and publishes on the draft page. The listing goes live as soon as it passes Homejourney's automatic checks.

  • As JSON: /sell/ai-assistant-guide.json
  • Over MCP: get_owner_listing_checklist on https://ai-apps.homejourney.sg/mcp/public (no sign-in) or https://ai-apps.homejourney.sg/mcp (signed in, where the draft tools are).
  • For owners: how it works and the price at Sell or rent your home.

Steps, in order

  1. Save the details as a draft (done by the assistant)

    Collect the required fields below, confirm them with the owner, then call create_listing_draft. Saving a draft is free and private.

  2. Add at least 3 photos (done by the owner)

    The owner uploads the photos on the draft page. The agent may declutter photos first but cannot upload them; decluttered photos may replace the originals and are tagged.

  3. Add a floor plan (optional) (done by the owner, optional)

    The owner uploads it on the draft page. See floorPlan for where to order one.

  4. Verify with Singpass (done by the owner)

    The draft page starts Singpass for an owner who has not verified yet. Only the owner can do this.

  5. Join Homejourney Pro (done by the owner)

    Publishing needs Pro at S$1 a day, billed S$30 a month. The owner pays on Homejourney; the agent never pays.

  6. Confirm and publish (done by the owner)

    The owner confirms they own the home or are authorised to list it, then publishes. A listing that passes the automatic checks goes live at once; one with a price far from similar homes or that looks listed twice waits for a person, usually within one working day.

What to ask the owner

Ask for every required detail in one message. The argument name is what create_listing_draft takes.

Photos

At least 3 photos, up to 15 files of 10 MB each, as JPEG, PNG, WEBP, HEIC.

Before you hand the owner back to Homejourney, use only the owner's own photos of the listed property. You may use your own image tool to remove loose items and visual clutter, or to fix lighting and exposure, without distorting, inventing, removing, resizing, or relocating permanent property features. Never change the layout, finishes, view or condition, never hide stains, cracks or other defects, and never use a fully AI-generated image of the home. Virtual staging is optional and follows the same rules. Tell the owner which photos you decluttered or staged, so they upload those as decluttered or staged photos; Homejourney tags each one "Virtually staged" wherever it shows. The listing needs at least three photos, and every one may be decluttered or staged, as long as each starts from the owner's own photo of this home. The owner chooses the photo order and the cover. A floor plan is optional. Do not upload media through the AI connection.

Floor plan (optional)

If the purchase papers or sales brochure already have a floor plan, a clear photo or scan of it works.

  • A floor plan is optional. To get one, order it from HDB e-service: Buy Floor Plan of HDB Flat (https://services2.hdb.gov.sg/webapp/BC31ISOP2/BC31SMain). Cost: About S$5 per plan, paid by Visa or Mastercard. HDB shows the exact fee before you pay. Timing: Usually a PDF to download right after payment; otherwise HDB emails or posts it to you. You need: Singpass, and the flat's full address. If the purchase papers or sales brochure already have a floor plan, a clear photo or scan of it works. When it arrives, add it to your draft or live listing in the Homejourney dashboard; the photos you saved stay as they are. Homejourney does not order or pay for it. Checked 2026-10-20.
  • A floor plan is optional. To get one, order it from BCA Property Plans Search (https://www.bca.gov.sg/pps/). Cost: S$45 to search one address, plus S$65 per plan, GST included. Timing: BCA replies within 10 working days. You need: Singpass, and a current Property Tax Statement that shows your full name and the property address. If the purchase papers or sales brochure already have a floor plan, a clear photo or scan of it works. When it arrives, add it to your draft or live listing in the Homejourney dashboard; the photos you saved stay as they are. Homejourney does not order or pay for it. Checked 2026-10-20.

Homejourney Pro

Publishing needs Homejourney Pro at S$1 a day, billed S$30 a month. There is no free trial.

What the assistant never does

The agent saves and edits drafts only after the owner confirms the details. The owner uploads photos, verifies, pays and submits; the agent never pays or submits.
