Hi,

The devaluation timer (the one that continually lowers the price of the plot) has nothing at all to do with the random timer that marks a house as unavailable after it demolished. Unfortunately there's no visual indicator of that timer and although SE has never said anything about the range of it, from what others have worked out it is between 30 minutes and 22 hours.

Yes unfortunately it's that large of a window and can happen at any point during that period, unlike demolition which at least is only on the hour. The only way to know is by trying to purchase again and you'll either get the "Unavailable at this time" (or whatever it says) or it'll let you buy it.

If you already have a properly you can bypass this timer by relocating, but from what you've written unfortunately that sounds like that's not the case.
