Zillow, schmillow. You're making it more difficult than necessary
I recently signed up at Personal Capital to track spending, net worth, etc., and I linked my home value estimate from Zillow, and my home value estimate is changing daily by swings of up to $50k plus.
Help me out here, because I don't understand. Are you saying you check these data on a daily basis? Do other people do that?
I think there are two reasons this is a bad idea. One, this is a retirement forum, yet you contrive for yourself an extra task each day. A reasonable person might consider this counter to the concept of retirement. Admittedly, I'm a lazy lump whose retirement goal is to REDUCE the number of tasks I have to do each day, so maybe I'm an outlier. But I don't check my PF more than a dozen times a year, and even that's probably too often. Similarly, most days I purchase nothing, so there would be no need to track spending every day.
The second and more important reason is that, unless you have an asset allocation of 0/100, your NW is likely to vary a LOT. Real estate, stocks, gold, pork bellies, artwork, classic cars, bitcoins, etc.; they all bounce around constantly. If you follow your investments too closely, every fluctuation could potentially influence you to react in ways you'll wish you hadn't.
I calculate it into my net worth because, well, it's part of my net worth. And we're not living in our forever house, so the equity is something that will be used one day.
Sure, "one day" you'll roll your current equity into your forever house. But if that day isn't imminent, what is the urgency for checking it on a daily basis?
If I simply "do not get it", it wouldn't be the first time, so I'd appreciate if you could explain why you do this.
