Foreclosure has started, getting ready to move now, how long am I liable for the home?

I live in Georgia and I have been receiving letters for my landlord from lawyers. I am suspecting that my home may be at risk of foreclosure. My landlord has told us nothing and I am worried that I may lose the house I am renting. Having no time to prepare and I am afraid that I will be out in the streets with no place to go. Can anyone please offer any help or steps I need to take in regards to this?

How does one deal with a foreclosure? Is the buyer allowed to look inside the house and should one go to bank if interested in buying a foreclosure home.
