If there aren't comps there I personally would value the property relative to its potential rental income using either the gross rent multiplier or cap rate method. 

I guess I would take it one step at a time and not let him bully you.

So, firstly I would like to know what my first steps will be as well as what I need exactly to start off.

Either way the process is still similar with an attorney there’s one additional step.

I want to get some advice from professionals like you and what my next steps should be.

hey, new to this site, amazing work you are doing here, every time i step in to ask a question i got ton of valueable responses, really great. i have suggestion i think can benefit everybody, having the ability to "star" a message in the forums.many times i read through the forum finding a really good insightful post, which has many things i would like to keep in mind for the future, i would have been great if it was able to mark/star the post and have a page with links to all the posts i previously starred. something to keep in mind..

On what to expect any learned methods that I could apply?

If it looks like there is money a contractor will step up. 

To give a little background, my aim is to focus mainly on BRRRR investing using what I've heard in the podcasts referred to as the "Stack" method: starting with SFH and working my way to small MFH and eventually Commercial MFH. 

Look up your state and real estate licensing and it should show you the steps to get licensed.
