I just found out that my landlord is trying to sell the house out from under me, what do I do?

I found out today that my landlord has apparently put the house I am renting up for sale. I moved in the end of February, and when I found this house and called her, she said that the house is for rent and she would be willing to work with me on the deposits. Nothing was mentioned about the house being for sale OR the house possibly selling while I was living her. Today I get home to find a car in my drive way that I did not recognize. I got asked and asked if I could help them. The mother and daughter said they where wanting to look at the house because it was for sale. I told them it wasn’t to my knowledge, and asked if they had the right address (apparently there is 2 of my addresses in my city) and promptly called my landlord that did not answer. I left a message saying hey there is a mother and daughter here to look at the house, they say it’s for sale and I was not aware of this. I talked with them for a little while longer and the left. I then went online to find out if the house was indeed for sale. I went on about 10 different sites and come to find out it is indeed for sale, and active. So I called the real estate agent that the lady was working with, and posed as a buyer. Come to find out IF the house is for sale (which it is according to her) and there is a tenant living in the house, the tenant and the landlord would have worked out an agreement for the possible sale of that house. Since my landlord never even told me that the house was up for sale I am wondering if you guys could help me figure out what to do. I have already called JAG (my hubby is in the military) and another attorney. I have attempted to call my landlord about 5x and still no answer. I know she is in violation of the lease because she has to give 24hrs notice that a some one is coming over. Unless it is an emergency she has to give notice. She didn’t and I come home to find people in my drive way wanting to look at the house. I am wondering what I can do tonight, what I should do when I actually talk to her, etc. ANY help is greatly appreciated.
THANKS
