Ideas

kind of like HGTV's website when they do dream house and they give you a 3D tour, that is really cool. it might be a good idea for real estate agencies if it's not too costly

might work. I know that something similar is available to see hotel/cruise ship rooms, so why not.

does Yahoo or something offer something like this? I know you can see photos from houses for sale and there are "virtual walk-throughs" but I don't know if your idea is the same as one of those.

Thanks for your comment imogene2004

The HGTV site mostly allows you to design a home rather than see a home on a real estate portal with a 3D walk-thru. I'm looking at someone who could help me setup such a kinda project.

The cheapest and shortest way, I think, could use something like second life, just placing your buildings/houses there.
The realtor's office could have a big screen connected to a computer and Second Life installed.
Clients would be able to walk thru an image almost in real size.
Another option could be a 3D engine like Unity3D, used mostly for games, but I guess that nobody cares what is behind the scenes, right?

Have a look at reel estate may you can get some ideas

opentoview.co.nz has this already. save your money and buy their software.

I've seen this many times. I believe a lot of top flight realtors already offer this.

I think kennybeck is right. Some realtor sites have it some don't. Some smaller towns/offices may go for your product. And what about for rental sites? They might buy the product rather than having to develop it themselves. But then you'd have competition.

its a cool idea, where i am from the Caribbean, you don't get that type of services... so it depends on where your market is, for your idea to work successfully. i pretty much would go for it because of how technology is growing it would help real estate companies adopt to the fast growth of today's technology.
