I don’t regularly look except to see what is available at the current time in case of a good deal (unlikely).
Any sort of “gain” one has is on paper anyway, until one goes through the painstaking process of selling. And then above the capital gains exclusion limit, (on your primary only) you then get to deal with paying taxes or in the case of rentals, 1031 exchanges.
Plus, the way I figure, the more I look at any sort of paper gain, the more disappointed I get if things were to go down or stabilize.
Kinda like getting a bunch of unvested stock options or RSU, and then being disappointed when, by the time you vest, your company stock tanks….Lol.
