From there, you have to decide whether you want to be a landlord or hire a property manager.

My first thing is to start built relationships with realtors and property managers.

Then you can self-manage and learn all about tenants, contractors, etc. 

What kind of ROI i should look at, considering project completion will be 3 years roughly?

I am based in Virginia and licensing requirements here seem manageable.

My wife and I started managing more properties for others as word of mouth recommendations started and we started to use the management and arbitrage cash flow to acquire our own properties and fund the BRRRs we were working on.  

I have a mobile home park in Idaho which will have an onsite property manager.

. - RentReady repairs & vacancies between tenants can blow any projected ROIs.2) Warren Buffet - go where others aren't.

When it comes to experience I have facilitated my fair share of successful projects, however the point still remains that I did not complete those deals completely independently.

Someone with limited ability to manage 2 or 3 SETS of contractors is not going to have successful rehabs.
