Thanks folks! I will look into this a further. Re: Rattler's question: I applied 20 years ago, and was awarded 100% 15 years ago. Your question raises a concern. Can my application result in a reduction in rating? If so, then this is not something I will do.
I had been homeless for over 10 years prior to getting rated, and then section 8 housing. I can't ever go back to those days. I am 76 now, not doing too badly!
