Hello MaNaAk...... it really is a sad reflection on your brothers on how they are treating you, they have no understanding of what you did willingly for your parents while they were on the sidelines living their lives......and they are too selfish to ever understand.
But you are in control of you and your life, not they, I think they are sending you possible properties because they still think your dragging your heels and not seriously looking.
The sooner the property goes on the market the better......It’s disgraceful that they even suggest paying rent in your case after all you did for your parents it’s totally uncalled for in your case.
You obviously can’t buy anything until the house is sold, have you looked at possible social housing in your area for over 55’s.....please look as it may really suit you, be a long term solution and that means you will have money behind you to enjoy life (once things get back to some sort of normal of course).
The other alternative if the stress put on you by your brothers does become unbearable....will be to rent, not ideal, as means moving twice, but maybe needed to save your sanity.
It’s such a difficult time, made harder by your brothers being unsupportive, but you really do have to focus on this move, really look at places your interested in and like I say get the house sold.
Only when your in your own home can you really begin to settle down, you will do it, you have nice supportive friends around and are strong when required.
We are all here sharing your journey and supporting from afar.....take care x
