I know that now it is possible to look at the VR tour of your future flat before buying. Is it the truth?

Yeah, I have seen it. It looks very realistic and it is better than just to look on the pictures

Yeah, it is possible and depends on the construction company that you are working with. The professional 3D designer makes such 3D models and it really helps to understand how your future flat will look. You can check some additional information about it and watch pictures in this article https://visengine.com/real-estate-3d-visualization/ . I have never seen it by myself, but I suppose that it is interesting to walk around the VR flat.
