My current property management company doesn’t offer this service, and the only company I know of is very hard to communicate with.

General phone numbers are rarely answered and we are forced to communicate most times via email.The word of the day is patience. 

You may want to make an introduction between your CPA to those 2 colleagues.The CPA can go over their services and pricing to your colleagues.I partner with many people on real estate deals - It never gets to a discussion on whether they do their own tax return or hire a professional.If a partner mentions he will provide capital - does he provide the capital on a timely manner.If a partner mentions he will find deals - does he find many deals and provide an analysisIf a partner mentions he will manage a property - does he manage the property well(find tenants, collect rent, communicate with contractors, etc)

I charge 20% straight to co host which includes vendor/guest /cleaner communication and managing the property.

Or heaven forbid I'm channeling someone here - buy the duplex and rent your own house for a while.Unless your current house is a killer rental scenario you'll almost always do better selling it and taking the money tax free.

Hi @Raymond Kalonji I would follow what all have said here, but I want to highlight one thing while working with section 8 or any other tenant is very important "timely communication".
