I would be asking questions, then some more questions.
Does the care home actually want you as a volunteer?
Are there any other volunteers you can take for a coffee and chat to? do they feel like a welcome addition to the team or is there anything you need to know?
If you are thinking of downsizing, losing land and still needing a mortgage I am thinking the town must have more facilities which might be nice?
I would be asking about good areas and bad areas.
Any new roads planned?
I might consider a visit to the planning office just to ask if there was anything I should consider if I moved to the area? It might sound like a stupid question but I would kill them with kindness and tell them a story about being on my own and not being able to make a mistake, and you never know what they may tell you?
I would consider public transport to local shops and facilities, you may not have your car forever and need to think how you would operate without one.
Maybe go to some where like a library and if you see a staff member under occupied, pin on your most charming smile and pick their brain.
Perhaps get a valuation on your property then try and establish what your money would buy?
Try and imagine if he is not around in one years time, will you mourn the house which has the memories you both made, or are you in a mental place to be able to start again in the new town.
I am presuming you only have half his pension money and he hasn’t been in the home that long, make sure you are 100 per cent positive you can afford a mortgage, there is nothing a nice as owning a property outright.
Do you always rush to the town then home again? Could you book a cheap hotel or guest house for a few days and just explore the whole area in more depth ?
