Fees vary by market and management company and when you have scale. 

I decided to go the syndication route, because investors kept asking to get into my deals and it was what would allow me to buy at the scale that I wanted. 

I would like to scale more aggressively which I am slowly doing, but I am tempering that with ensuring I am not overly leveraged. 

If you want to scale then go bigger.

Initially my wife and I plan on BRRRR'ing single-family homes and eventually scaling up to multi-family.  

Those C and D class properties are best served to sophisticated local investors. and above all if an investor cannot scale to five properties at the minimum in a two year period. they should not be OOS.

I can do the PM on there eventually, but I'm still kind of a noob looking to gain experience before scaling.

I realize I have more units and more points of contact, but you get some economy of scale with all units being in the same place. 

It does seem as though those lower on the socioeconomic scale might have more resentment toward a landlord than more wealthy tenants.

Always multi-family so you have an economy of scale.
