IF this was a legitimate banker coming to your door....chances are, the landlord has already been taken to court and 9 days is the amount of time the courts have given her. so you very well may have to move out really quick.
i own a property management company. every state has different laws but if the landlord is being foreclosed on, you are really S-O-L in this situation. I get new tenants because of this all the time.
you can take her to small claims court if you have to move out suddenly because of this.
i would start looking right away, in case the 9 days is in fact her last chance of keeping the place. you don't want to come home and have your stuff locked in the house. they will keep all your stuff as "payment" even tho it is yours and not your landlords. just protect yourself here.
i wish i had better news for you, but honestly, i wouldn't wait around to see if they really are taking possession in 9 days. start looking right now. many places aren't able to accommodate "immediate" move in's. so you want to give your new place as much notice as possible.
good luck. if you lived here i would rent you a nice house
