When is it time to change realtors?

I know the housing market is shite. We were renting out our old house in Houma, but have been trying to sell it for the last 5 months. She said she was gonna have an open house, but hasn’t-she had said people really don’t do open houses anymore with the internet. She’s kind of friend of my wife’s, so that kind of complicates things, but I’m not sure how much she is doing. I don’t think she has even posted it on her facebook. All she has said is about lowering the price. TIA
