Real estate social media posts: listing ideas, sizes and captions

Post ideas for every stage of a listing

One listing can carry a month of posts if you plan them as a series. In NAR's 2026 Home Buyers and Sellers Generational Trends report, agents marketed the home on social networking sites for 23% of sellers who used an agent, and for 41% of sellers aged 27 to 45, so the sellers most likely to expect it are the younger ones.

For more shots to fill the series, see real estate agent photo ideas. If you only have photos, you can turn listing photos into a video, though a real walkthrough shows how the rooms connect better than a slideshow.

Image and video sizes per platform

Platforms change these often, so the figures below are dated. They come from Sprout Social's image sizes guide (updated October 15, 2026) and video specs guide (updated October 16, 2026), which list the platforms' own in-app limits:

Two practical notes. Instagram's profile grid shows every post at 3:4, so keep the house centered in a 4:5 photo; and in Stories, Sprout Social advises keeping text out of the top and bottom 14% of the frame, where the profile icon and reply bar sit. Export vertical video as 1080 × 1920 MP4.

YouTube's own help page confirms that square or vertical videos up to three minutes, uploaded on or after October 15, 2024, count as Shorts.

Real estate Instagram: what works for a listing

• Lead with the strongest photo. The first image is the only one most people see in the feed. Use a bright, level shot of the front or the best room.
• Order the carousel like a showing: outside, entrance, living room, kitchen, bedrooms, bathrooms, yard.
• Make the reel a real walk, not a slideshow: one steady route, every light on, about 30 to 60 seconds. Our guide on how to film a house tour covers the route.
• Put the facts in the caption, not only on the image: price, beds, baths, square footage, neighborhood and the open house time.
• Use the location tag and a few local hashtags (the city or neighborhood) rather than long lists of generic ones.
• Pin the current listing to the top of your profile while it is active.

Captions and fair-housing-safe wording

The Fair Housing Act makes it unlawful to publish any notice, statement or advertisement for the sale or rental of a home that indicates a preference, limitation or discrimination based on race, color, religion, sex, handicap, familial status or national origin (42 U.S.C. § 3604(c)). A social post about a listing is an advertisement.

NAR's fair housing marketing training gives a simple test: does the post describe the property, or the ideal buyer? It also warns that there is no authoritative list of approved words and that context matters. In practice:

A simple caption pattern for a just listed post: one line on what stands out, the facts (price, beds, baths, square footage), the open house time, and where to see more. For example: "Just listed in Maple Grove: a three-bedroom with a new kitchen and a big fenced yard. $485,000 · 3 bd · 2 ba · 1,850 sq ft. Open house Saturday 1–3 pm. Link in bio for the full walkthrough."

NAR's Code of Ethics also requires your firm's name to be readily apparent in any advertising, including electronic (Standard of Practice 12-5), so add the brokerage name to the caption or the image.

Before/after posts, honestly labelled

Before/after posts get attention, and they stay honest when the label says exactly what changed: "Before and after staging", "Before and after the kitchen repaint", "Virtually staged". Don't post an edited photo as if it were the room as it is today; NAR's Code of Ethics prohibits manipulating listing content in a way that produces a deceptive or misleading result (Standard of Practice 12-10).

Posting a listing that isn't yours

Agents often want to share a colleague's listing or a home they sold to a buyer. Two rules apply. First, the Code of Ethics says REALTORS® shall not advertise property without authority (Standard of Practice 12-4), so ask the listing agent before you post their listing. Second, the photos usually belong to the photographer who took them and are licensed for that listing's marketing, so permission to post the home isn't automatically permission to reuse the photos; see who owns listing photos.

For just sold posts, Standard of Practice 12-7 says only the listing broker or the cooperating (selling) broker may claim to have sold a property, and before closing a cooperating broker may post a sold sign only with the listing broker's consent. If you represented the buyer, say so: "Helped my buyers close on this home".

Photos and a walkthrough for your posts

Every post in the series starts with good photos and a walkthrough video. The October app is one way to get both from your own phone: it guides you through each room on an iPhone 12 or newer, showing where to stand and keeping the phone level, and an image model then makes finished photos from your capture, usually within a few hours, along with a walkthrough video. A place is up to 6 rooms; a bigger home counts as several. Photos cost $49 a place, $99 with a walkthrough video, and the first place is free. Check each photo before you post it. See pricing.
