Hi @Neil715
I would not use a property management company as they generally require you to name them as owner on the listing. If you terminate your agreement, then all the reviews go with them. Most also don't seem to do a very good job either.
I would instead look for an experienced Co-Host who can help you. You remain as Owner/Primary Host and invite a Co-Host via email to the listing. Negotiate compensation based on what tasks they will perform. Most will either be local and able to do cleaning, maintenance, etc. or a remote Co-Host (like myself) who can handle all aspects of the listing except cleaning, or on site tasks. You can join one of the New York Host Clubs on Facebook and ask about getting an experienced Co-Host:
