Real estate and project advertising comes down to three broad points: content must match the facts, brokerage ads must show the brokerage's name, and nothing may be false or misleading; presale housing has further rules on top. These points come from the Real Estate Broking Management Act, the Fair Trade Act and the rules for presale housing. This is a plain-language summary, not legal advice; actual rules and details follow the latest notices from the authorities, such as the Ministry of the Interior and local governments, so ask them or a professional if in doubt. Below are the three points, then how they apply when writing your website, listing pages and AI assistant replies.
1. Three regulatory points
| Regulation | In plain language | What it means when writing |
|---|---|---|
| Real Estate Broking Management Act | Ads and sales content must match the facts and show the brokerage's name | Listing pages, agent pages and social posts state the facts correctly and show the brokerage's name |
| Fair Trade Act | No false or misleading advertising | Floor area, transport, facilities and nearby development aren't exaggerated or written in a misleading way |
| Rules for presale housing | Presale housing has additional rules | Before a project's ads go live, check the latest rules with the developer and sales agency |
This table covers only the broad direction. For the details of each rule, when it applies and the penalties, follow the authorities' notices.
2. The wording that causes the most trouble
Most problems aren't deliberate deception; they come from writing on autopilot. Here is common wording and a safer alternative.
| Common wording | Possible problem | Safer wording |
|---|---|---|
| Near the metro | Distance is unclear and easy to misread | Which station, how to get there and roughly how many minutes, with the source stated |
| Cheapest in the area | A superlative with nothing behind it | Leave it out; point people to the agent or the actual price registration |
| Prices will definitely rise | Amounts to promising an investment return | Leave it out |
| Floor area given as a single total | People may misjudge the indoor space | Break it down as in the official documents |
| A new metro station is coming | The plan isn't confirmed yet | State the current status and source, or leave it out for now |
| Posts without the brokerage's name | Brokerage ads must show the brokerage's name | Put the brokerage's name on every post and every page |
3. What to do on your website and listing pages
- Tie every fact (floor area, layout, shared facilities, completion date, transport distance) to documents you've confirmed
- Prices and market trends aren't written by whoever writes the copy; leave them to agents or the sales team, or point people to the government's actual price registration
- No superlatives, and no promises about price gains or rental returns
- When a property sells or is withdrawn, update the page so old details don't stay online
- Show an update date on each page, and change it whenever the details change
4. AI assistant replies are public statements too
Automatic replies on LINE or by phone are, to the customer, what you're saying publicly. So the AI assistant answers only from the data you provide: listing basics, project information, sales center hours and how to book a viewing. Prices, negotiation, loans, legal and tax questions always go to your staff, and it doesn't guess anything that isn't in your data. When a listing is withdrawn or details change, the data behind the automatic replies changes too.
5. How we write content
When TriloAI writes website and AI-readable content for real estate businesses, every listing or project fact comes from documents the client has confirmed; we don't state prices or market trends ourselves, and people asking about price are pointed to the government's actual price registration or the client's staff; we use no superlatives and promise no investment returns. The version the client confirms is the one that counts.
The short version
The safest real estate advertising states facts from the documents, shows the brokerage's name, and leaves out prices, market trends and superlatives, with details following the authorities' latest notices.
Frequently asked questions
- Can I treat this article as legal advice?
- No. This is a plain-language summary, not legal advice. Actual rules follow the latest notices from the authorities, such as the Ministry of the Interior and local governments; for a specific case, ask the authorities or a professional.
- If an individual agent runs their own social media, do posts need the brokerage's name?
- Listing posts by an agent are still public advertising and sales content. We'd recommend every post shows the name of the brokerage they work with; for details, follow the authorities' latest notices.
- Can our website show recent sale prices in the area?
- When we write content we don't compile market prices ourselves; we point people to the government's actual price registration or to an agent. That avoids errors from outdated data or different interpretations.
- What additional rules apply to presale advertising?
- Presale housing has additional rules, and they may change. Before a project's ads go live, check the latest rules with the developer, the sales agency and the authorities; this article is only a plain-language summary, not legal advice.
