I have two areas I would like to go( wholesaling or house hacking with the BRRRR method) however I am someone that learns faster by seeing and talking about the minutia of process.

@Juhi Banerjee, appraisers for 2-4 units will use the same valuation methods as a single family home: Sales comparison, Income and Cost approach, with a reconciliation section to account for the variances.  

@Henry Lazerow Not only is it state law (most states) to have a written representation agreement, most professionals use contracts to ensure payment and detail services rendered, instead just going with the hope and prayer method. 

Some questions that I thought about asking are:1. what comes to mind when you see a FSBO sign on home that doesnt appear to be a mess2. what methods would you use to contact homeowner, and what do you say3.

If I was audited, I can prove I claimed all my income on my taxes.The only payment method that cannot be traced is cash, provided you receive it as cash and spend it as cash.

Brrr method suggests that investors should invest in properties that are located in good school districts since it would later help for resell value.

The reason I ask is that the method of acquisition has a big impact on the financing structures possible. 

Can you raise capital through any of either method? 

And what method did you use to buy it originally?

For one, your appraisals use an entirely different method which can definitely be in your favor.
