I need my brother to come live with me to help me. How can I make this happen for me?

Still thinking...is your brother disabled? How is it that he is available or needs a free room in exchange for caregiving? If you did not need his help, would he be the right person to move in and share rent, could he afford rent? How old is he, does he qualify by age if this is a MH Park requirement?
What is your history with this brother? Have you been mutually supportive in the past? Can you find a younger person to caregive for a contractural amount of time in exchange for a room? Be sure they have their own home to return to and are not homeless. These are all things for you to consider, you don't have to answer me.
Wise advice I once received: The future is so much like the past and present, only there is more of it.
You are correct to be making plans now for the symptoms you explained. Stay as independent as possible, for as long as possible, this will help with depression.
Do a review of your medications, some of which may cause dizzyness or falls.

Get his room ready. Before he moves in, could you do better wth frequent visits?

Check your mobilehome residency laws. He could come in as an unpaid caregiver, with no rights to residency after you leave.
Carefully consider where you got the idea that you are not "allowed" to live with anyone. Review those rules in writing. If the rules are from S.S.I./government, perhaps they refer to the financial requirements of income. Your brother's income can be factored into your qualifying for S.S.I.

Mape6273, life might be more enjoyable if you qualify for Medicaid [if not already] and find a really nice retirement village where Medicaid will pay for your care. You'd be around people of your generation, no more worry about maintaining your home and yard, no worries about broken water tanks and what might break next, no worries about leaving something cooking on the stove, etc. With such facilities, you would actually have MORE freedom than you do now.

Even if your brother does come to help you, there will be a time when he will get burnt out and exhausted, and he might regret uprooting his life. Unless he finds employment outside of your home so that he can be around other people.

But she would have his income - or at least the household would, which, surely he would understand that, if he's willing to come, so would it matter?

Because his income would, by law, have to betaken into account. That could men she would lose her subsidy.

why can you not have anyone live with you?

Do you deal with a social worker in your area? Or can you contact social services for advice?

Maybe someone else can help you. I don't know the answer.

I will ask how much help you get and whether or not you could forego that assistance in order to easily have your brother live with you.

I receive assistance wit hmy lot rent from gov. I am not allowed anyone to live in my home, Yet I need and asked my brother to live with me to help me, What is the legal procedure for this.How do I make him my care giver without paying him or him paying me to live with me.

What's the problem? He says he's willing.
