I believe more often than not the main folks who really benefit from turnkey deals are the people who rehabbed them and the people who sell them. 

The main pro is cash flow  - C-class as a whole tends to offer better cash flow than a higher class property in the same town (purchase price VS rent tends to be at a better ratio in C-class). 

@Mingze Wang PITI and PMI are the main costs you'll encounter. 

I would like to learn more but when I look up articles it mainly comparision of standard rentals vs air bnb. 

I'm mainly looking for a general type of maintenance guy to handle most common requests and if something comes around that is over his head, that's when I could go to the specific contractor. 

On the other hand, creating a C corporation for managing these LLCs and/or properties could have a lot of tax benefit and tax shifting strategies.

My main indicators are crime, schools, median income, and homeownership ratios.

The main point is to find distressed properties to get the biggest discount possible.

I am starting a new job and as one of the benefits, the company will match dollar for dollar up to 3% into an IRA. 

Hiring a lawyer will cost you more, but you will (hopefully) get the benefit of their knowledge and experience and then you can learn from that knowledge and experience.
