Hope it all works out for you Peggy and I echo the others when I say what a beautiful home! I love the wrap around porch it would be so great to sit out on it in the evenings.
I'd also test drive it for sure especially if its an older model. if there are issues with it while your making payments who is on the hook for the repairs? I'd ask her if there were any problems with the machine in the past, maybe get her to put it in writing?
