When I asked him about this he said it's a bit complex.

.- I live in Raleigh, 10-50 unit complexes will be hard to come by unless you're okay paying a premium.

Final comment, it seems complex.  

Thoughts and suggestions or too complex and take the hit on capital gains tax as I sell my rentals?

If you hire a PM, your financial account structure can be simpler.If you plan to continue purchasing rentals, I like some key accounts at the "management" level (income, opex, tax, owncp, reserve) and only have 1 checking account per property to prevent having 100 accounts and unnecessary complexity.

Here’s MY general feeling; if a MHP isn’t TOH, or I can’t easily switch from POH to TOH, then I might as well purchase an apartment complex and have less problems.

Or a small complex.  

Over the past decade I have invested as an LP in about 50 apartment complexes. 

Should I sell and 1031 the equity into a apartment complex where I can increase my net per month?

They already cancelled many large complex deals or doubled their price for the past few years.
