My mother and father sold their house to my eldest sister eight years before my father's death and my sister charged a nominal rent fee. My mother lived for another five years and two and a half of them were in a council run home. A home that was above average, if I may say so, and the carers were, and did more, than what they were paid to do. I'm forever grateful to the staff at Hafod-Y-Gest which was Council run.
morddwyd, timing of transferring property is of great importance in this situation. Sorry to hear of your wife having to go to full time caring.
