There is an emotional attachment to the house. It's nothing special, just a normal semi on a 1960s housing estate. But she and my dad moved in together not long after getting married, and it's where me and my sister were brought up. We have discussed that she may need to move in future, but she's not keen on the idea. I may be odd but I have no interest in the inheritance value of the house or any of mum's assets. In reality there's a high chance they will be needed to cover care costs at some point, anyway.
She's fully independent. She struggles with a few things like changing lightbulbs but I do that for her, or if I'm not around her neighbour will do it. Two of the bedrooms are used as guest rooms - one for me when I stay and one for the grandkids if they stay. The third isn't used. I have managed to train her to use the thermostatic radiator valves in the spare rooms so at least she's not paying to keep them warm now, unless guests are in them.
If she was in a position where she was struggling to pay the bills, then she would do something like that, or go to my sister's (who lives near by). But as things stand, she can afford the bills and will be able to afford them even when the prices increase, thanks to the pension arrangements my dad made. So whilst she doesn't want to waste money, she also doesn't need to make drastic changes at the moment. On the other hand, if my dad hadn't had the foresight to pay into his pension plans, then she would be really struggling now.
