Agreed – make sure she is spayed if you’re looking for a specific temperament.
I do believe Lops are known for their docile temperaments though. Bunnies are typically skittish when meeting you for the first time. I would just play it by ear and see how it goes. My fourth one Simba, we were looking for a “lap bunny”. He was very skittish at first and didn’t come to me right away and wouldn’t even take his favorite treat if offered. But once home, he settled in great. He loves cuddles and giving kisses. And is very easy to handle.
I would suggest having the person you are getting him from show you how well he does being handled by her. This should give you an idea of how he is with his “family”. Simba jumped in his foster mommas lap and was cuddling into her because he was nervous. He was used to her and you could tell by his relationship and reactions with her that his reactions to us were simply him being nervous and scared.
