Charlie girl needs a new home

Charlie is housetrained and currently uses a combination of a litterbox and the great outdoors.
Charlie has visited the vet in mid February for her vaccinations, worming and flea treatment and was checked over. She is a little overweight but in good health and is microchipped.
I am looking for a lovely, kind home for Charlie, I think she would be well suited with an older couple or single person as this is what she is used to. She loves people, is a very gentle cat and is getting quite lonely on her own. With my brother going into residential care, Charlie needs a new home as the house needs to be sold. I really wish that I could take Charlie in but I am unable to due to already owning a very territorial female cat who we love dearly too and to do so would be unfair on both of them.
