Sharing a 3D walkthrough on WhatsApp and text: how to use it to sell

A 3D walkthrough is shared on WhatsApp, or by text message, iMessage or any chat app, as a link. The buyer taps it, it opens in the phone's browser, and they walk through the unit without installing anything. They can open it again later and forward it to whoever they're deciding with. In much of Latin America, Spain and many other markets, WhatsApp is where real estate conversations happen; in the US it's more often a text. The logic is the same either way.

Why is a chat the natural home for a walkthrough?

Because that's where the conversation with the buyer already is. The first question comes in by message, the follow-up goes by message, and the decision gets discussed by message with a partner, a parent or a friend.

A heavy PDF downloads badly and reads worse on a phone. A long video gets watched once. A walkthrough, on the other hand, the buyer opens when they want, explores at their own pace and opens again when their partner asks a question. There's more on chat as a sales channel in WhatsApp for selling apartments.

When should you send the link?

There are three good moments:

1. In the first reply. When someone asks about the project, the link to the unit type they mentioned is the best possible answer. It shows them more than any paragraph and lets them keep looking on their own.
2. After a call or a meeting. "Here's the unit we talked about, so you can look at it again calmly" turns the meeting into something the buyer keeps.
3. In the follow-up. When a few days have passed with no reply, a link to a specific room or a different time of day is a real reason to write again, not a "just checking in."

What should you write with the link?

Short, specific and about the buyer's unit. Some examples:

• "Here's the two-bedroom you asked about. Scroll through it and look at the light in the living room in the afternoon."
• "This is the 7th floor unit facing the park. It's still available. Tell me what you think of the kitchen."
• "I'm sending you the house with the porch. If you want, show it to your family and we can talk on a call."

The message tells the buyer what to look at and leaves the door open to reply. It doesn't need adjectives or exclamation marks: the walkthrough does the selling.

Forwarding is the most important part

Most home purchases aren't decided by one person. The buyer who wrote to you will show the unit to their partner, their parents, a friend who "knows about this." In a chat, that's one tap.

That forward is where the walkthrough works on its own: it reaches people who never wrote to the developer, never saw the ad, and are giving their opinion on the same thing the buyer saw. When the buyer comes back, the conversation has already moved forward at home. I also cover this in selling to buyers who live in another city.

Compare that with a showroom visit. What the buyer saw stays in their memory, and what they tell their family is a version. With a link, everyone sees the same thing.

Using the walkthrough in follow-up

Follow-up is where many sales are lost, because there's nothing new to say. The walkthrough gives you material for several messages that aren't pushy:

• The same unit at night, if the project shows different times of day.
• The view from a higher floor, if the buyer hesitated about the price.
• A similar unit that's still available, if the one they liked was reserved.
• The building's amenities, if they only looked at the unit.

Each message adds something, and the buyer opens it because it relates to the unit they already chose. More on this in following up on real estate leads.

One link per unit or one general link?

Both, for different moments. The general link to the building works for ads, social media and the first contact with someone who doesn't know what they want yet. The link to a specific unit type works once you know what the buyer is looking for, because it saves them steps and shows you paid attention.

In the Maconda XXIV building demo, an unofficial working demo based on a 12-story building in Quilmes, near Buenos Aires, marketed by Otamendi Propiedades, you can see how it works on a phone: the building on its block, the floors, the units and the walkthrough of each one. For houses, the Americana 35.64 house demo shows the same idea with a single home.

Give the whole team the same material

If you have several salespeople, they should all use the same links and the same base messages. That way every buyer gets the same quality of reply, whoever picks up, and the team doesn't improvise. See the 3D walkthrough as a sales team tool.

I work remotely from Buenos Aires, Argentina (UTC−3), and I deliver the walkthrough as a link ready to send. If you want to see how your project would look in a chat with a buyer, message me on WhatsApp at +54 9 11 6193-3176 or email facundocampo100@gmail.com. I answer in English and Spanish.

Frequently asked questions

Does the buyer need to download anything to see it?

No. The link opens in the phone's browser, on iPhone or Android, with nothing to install. That's what makes it work in a chat.

Should I send an image along with the link?

It helps. A good image of the unit makes the message stand out in the chat and gives a reason to tap. The link then does the rest.

Can I send the same link to everyone?

You can, but it's better to send the general link to new contacts and the link to a specific unit to people who already said what they're looking for. It feels more personal and saves them time.

Does it work for agencies selling the project too?

Yes. The developer and every agency selling the project can use the same links, so every buyer sees the same thing no matter who they talk to.
