Thinking about selling..need advice

I agree with cosgig ^^^^. You have to do what you think is right. But let me say this As I have made it all the way to 71 years old, this I know, as we age memories become very important. If we live long enough, memories will be all we have. Parents and relatives pass on, sometime, God forbid, we can lose a child.
Only you can know what is right for you and you only.
