My personal view is that some rage is entirely justified in this situation. My view only, but I think you were misled, possibly accidentally, but still misled. I also think that your family suffered a rush of blood to their collective heads when the process started, and their expectations altered in consequence as they realised all the various possibilities available. But imo they are primarily thinking of their own needs/wants, and I think yours got lost along the way.
Now, however, you are in receipt of much more accurate information and can go forward armed with that.
I do think that your family needs to consider whether or not they actually need to buy a dedicated apartment for their own use. One that has nothing to do with you and which fits their needs perfectly. You can even help them search for it. You can still offer hospitality as and when required if that suits you, but if they are going to be that picky about the space they need then they need to understand the consequences and costs - to you as well as them.
Your needs come first here. After all, you are going to be living in the space full time and your needs should be the priority imo.
This might be a bit cheeky, but you could ask if they will let you have a locked room, for your own exclusive use, at their house in Mornington. Because I bet they will refuse because 'it's their house'. This might bring home to them exactly what they are asking you for.



My heart hurts.
Iโm not angry. I was never angry. Iโm justโฆso sad. I wish I had understood.
This whole time Iโve been terrified of making a mistake and locking myself into a mortgage on an apartment that wasnโt the right one - I intended for this to be my home for the rest of my life, or at least for the next twenty years. I was so stressed about the possibility of picking wrong, and turns out I made a huge mistake right from the first because I hadnโt understood the nature of the agreement or hence the search.
I donโt know exactly what would be different if I HAD understood, but Iโd have set my hopes somewhere different and not be grieving them now
