This is why management fees will be not subject to SE taxes. 

I currently have a Roth IRA, a 401K at a previous employer, and 2 duplexes I self manage.

Plus you need to check and see if they require you to use them as management.

I am currently focusing on my credit and money management skills.

Background: I am scaling up an Airbnb Vacation Property Management Business.

Hello,Ive recently joined a team of two, who manage roughly 60 properties at the moment but will be at 200 by the end of the year, is there anyone who would be willing to connect and share advice on how to properly support this growth?

I manage 7 STRs and do not spend more than 4 hours a week managing them.

How well or poorly have properties in this area appreciated/rents increasedWhat property managers will manage the property, if any?  

If you keep buying then find a quality management company to take over the self management.  

Any property managers out there at specialize in Section 8 in Memphis?
