I'm sure all the realtors that have answered are very competent, and though I'm sure that many of them can get the job done, only one will get the chance to. When selecting a realtor, it's important that you choose one that fits the needs of your parents and thoroughly understand the situation they're in to select the best plan of action and help your parents transition smoothly into their next home. The most important thing a realtor can do for your is listen to their needs and guide your parents accordingly. I find the better I understand your situation, the better I can help.
If I'm hearing you correctly, your parents need to either be relocated or downsized. You may have questions on how to get that done to make sure that the process goes smoothly. It's advisable that you reach out to a couple realtors over the phone for a quick interview and feel them out to go with the one you feel can best meet the needs of your parents. I'm sure you'll come to the right decision.
