Same here! Most of our family know we have property, but that's as far as it goes. We learnt early on that discussing it with those who have no interest is a bad idea.
Here's a run down on how we were viewed:
Many years ago now, at a family gathering, we let it be known that we'd purchased an IP. Lots of congratulations, pats on the back, etc. You're doing well for yourself, coming up in the world, good for you....... All good!
A little while later when we purchased IP2, the comments changed to "Oh gee, you are doing well", "So soon!" "how can you afford that?" etc, with an expectation that our disposable income had also increased because we were 'rich'.
After IP3, it changed again to "Really?", "Don't you think you're being greedy?", "How many properties can you live in?" etc.........
Well, we went past IP3 a long time ago now. We don't mention it anymore. A couple of our family know we've got a reasonable amount, but they have an IP of their own. Others have no idea at all. They assume we've got a few, but the only time we talk about it is if someone is interested in it, & then it's basically only to answer their questions.
