I decided to get ahold of the funeral director from the town that she is from and am setting up all of the arrangements in case of her death along with the cemetery director so I can buy a plot near her family. Next I am making an appointment with an elder care attorney so she can have a will made up. Other than that I really don't know what else I am supposed to do other than what I have been doing like cleaning her house, making her meals, laundry, taking her places along with making sure she takes her meds and taking her vitals along with all yard work, etc, etc. if there is something else I have forgotten than please let me know. I now have a greater respect for all of those that have to take care of someone Day and night. My hat is off to you.
That will be so much easier on you, and on your neighbor's wallet. I sold my parent's house that way, and it sold fairly quickly at the professional appraised value. I was so glad I didn't need to take time off from work to meet contractors and have to make decisions on how to update everything. Just sold the house for less, and let the new owner fix it up the way he wanted it :)
What about her home? Does she own the house/condo or pays rent? Since your neighbor only has one living relative, without a Will the Probate Judge would probably give the assets to her brother. That is if there are any assets left to distribute, as there could be a chance your neighbor might need, at a later time, to pay for Assisted Living or a Nursing Home. Thus, sell the house for the funds.
Regarding the cemetery and funeral, I see from your last post that upon her passing, she wants to be buried in her old home town. When I did that for my Mom, it took two funeral homes to deal with the logistics, thus two funeral home bills, plus the cost of shipping via a commercial airline, and a lot of other costs involved. The total was $15k. Hopefully your neighbor has the funds.
It is important that your neighbor has a Power of Attorney, otherwise the State would take over and make health decisions for her. If your neighbor has a time of day where she is sharp, that is the best time to make an appointment with an Elder Law Attorney.
I can understand your neighbor's brother not wanting to help, he's exhausted from helping out his sister. With these 3 siblings, I wonder if there are any nieces and nephews, children, grandchildren.
