The number I would anchor on before making a move
If your question is whether home values in Corona, CA still support a move, I would start with the estimate that was reported most recently. The median estimated property value was $771,830 last month, and that is the number I would keep in view.
Last month, the median estimated property value was $771,830. That gives me a current reference point for anyone trying to decide whether their next move should be based on value, timing, or patience.
Corona, CA also showed a 6.1% last-month change in that estimate, so I would not treat the number as fixed. I would use it as a planning anchor, then compare it with the sale price side before making a move.
Start with the value level. Compare it with the sale price side. Then decide whether your next step is to move, wait, or price carefully.
