It’s 2:17 AM and you can’t sleep.

You’re refreshing Realtor.com for the third time tonight, watching your home’s estimated value like it’s a stock ticker. Yesterday it was $485,000. Today? $439,000.

That’s a $46,000 swing overnight—and your house didn’t lose a single shingle.

So here’s the million-dollar question (literally): Which estimate can you actually trust? And more importantly, what’s that uncertainty costing you?
