I know people who live in an apartment resist purchases by thinking "it's going to be a liability for my next move" which works quite well.
especially with art, "how hard is this going to be to clean?" helps too
Maintainance in general, excludes all IoT electronics right off the bat for me.
Living in an apartment definitely limits my purchasing. I'm not thinking about things being a liability for the next move, though. I'm thinking about now. I have limited space, so part of the purchasing decision is "what am I willing to get rid of to make room for this?". Often the answer is "nothing" and the purchase doesn't happen.
