My advice in responding to her letting you know about the house being listed is not to respond at all.

Or, depending on the vibe you wish to give, you could say something like - "Excellent! Let's hope it sells quick! Fingers crossed!!!!! (insert smile face emoji). Make sure you tell the agent we want a very quick settlement period."

I'm actually tending to the latter. Flips the script mate
