I have to agree with the previous response. I hope that I don't sound offensive but I have to say that your parents are responsible adults who should be able to deal with their own issues. My husband, who is a wonderful man, has parents that sound similar to yours. They have no retirement, no home, no investments, 50k in credit card debt and now are both having some very serious medical problems. Thankfully they have not come out and asked us for money because we don't have it to give. They do, however, seem to think that they can come live with us rent free until they get their issues straightened out. The problem is that they never will get their issues taken care of and neither will your parents. I think that perhaps, as hard as it may be, you and your sister need to sit your parents down and have a chat about the burdens that they are placing on your families and the unnecessary stress it is causing you. I know that it is incredibly difficult to separate yourself emotionally from your parents, because they are your parents, but I think that if you can do that and look at them objectively it will make it easier for you to see a solution to your problem. I wish you all the luck in the world!!
