You can ask your landlady about purchasing the home, but I would be very wary. Whether she got dragged into this, or jumped in willingly doesn't make a difference. There is something brewing here and you shouldn't wait around to see what happens. You should be socking away cash for either the purchase of this home, or another, or rent and security somewhere else.
It is a great time to purchase with the tax incentives available for first time home buyers, but you must close by November 30, 2009. Get yourself a good Real Estate attorney. I can recommend one if you so desire.
