Quicken allows you to enter a transaction with category that is basically a transfer back to the same account. As far as I can tell, that mostly just messes up the ability to generate reports because the money doesn't seem to belong to any category, so it's not shown as income or expense, and it seems to mask any profit or loss when selling it. Quicken uses this mechanism when you do an "update balance" to an account, or when you do a zestimate update on your home. I typically change the category to something like an appreciation or depreciation category that I've created, but then it looks like cash flow, which its not.
My questions is whether there is some real purpose for using a transfer back to the same account, and whether me changing it is actually preventing quicken to do something useful that I'm not aware of.
Most of the quicken functions are based on fairly straight forward accounting principles, but this one always seemed odd to me.
