Are there any pros cons to buying a portfolio over just buying multiple of your own single property?

I have gotten rental estimates from Rentometer that were WAY off for a duplex, because it was averaging the rental rates for some very nice single family homes in the area (SFRs can rent for much more than a duplex in some areas) I would call your local property management company and ask them about the specific property you are evaluating.

I help out clients part time (usually investors become I enjoy investing so much), but 3-6 single family homes per trade for rentals and get to look at homes on the market at will.

If this single family house were my only investment I would have struggled to cover the basic PITI, yes @Grant Cardone, you are right......  

Single family homes are averaging $1900 a month.

So, gain allocated to personal portion will be shielded with sec 121  ( 250k -if single) and gain allocated to rental portion can be invested into other investment property with section 1031 like-kind exchange.  

I want to form a Single Member LLC. 

Generally speaking though if you're not in a NYC/Boston/LA/San Francisco market then you should be looking to clear between $100-200 on a single family home after covering all of your expenses.
