After mom moved out of her condo, I had to pack up all of her belongings (of which she had alot) and then prepare to sell the condo. When speaking to a real estate agent, one of the first things I learned was that I needed a power of attorney in order to even begin the process. Since mom was mostly blind, constantly ill from UTIs and not in a position to meet and speak with realtors, I needed to be her representative.
I had to work with mom in order to get a "Power of Attorney Specific" document notarized. This document granted me the limited power to sell her condo. I did not give me any other authority. Later, I did sign a Durable Power of Attorney which gave me control over all of mom's affairs.
In any case, if your loved one is not in a position now or in the future to sell property or manage other financial or healthcare affairs, reviewing your POA options is strongly recommended. For me, mom agreed to almost everything I proposed. But your situation may be different if you have other family members who want to be involved in the decision making.
