If my goal is turnkey/buy and hold properties, should CoC really matter?

Real estate is very similar to exercise you need dedication, repetition, and a solid diet (education).

By "business account," I’m referring to setting up an LLC as well as a business bank account.My goal is to expand my real estate portfolio by acquiring approximately two properties per year.

My goal is to maintain good relation with tenants and have excellent communication.

At the end of the day, if you have a tenant you want to keep, talk with the tenant and see if you can get on the same page with them to align your goals as an investor with their goals and budget for their housing. 

Not sure if the goal is to buy turnkey or do a value add project.

I agree with the notion that one needs to define his or her goal with regard to real estate and making a living of real estate alone would require lots of it, but cash flow for the long run is almost inevitable.

The goal is to change careers to something that allows me to decide my hours (in the process of now), become a landlord, and finally spend more time with my kids and family. 

(at least for the first few properties) I do not need cash flow in the short run but my ultimate goal would be to retire early from my investment properties.
