BRRRR is not risk free, but no doubt buying undervalued properties is a good strategy to build wealth. I

Then I had my partner call them pretending to be a different investor and they negotiated a payoff where it was worth the sellers time as they are somewhat wealthy.

One path to wealth is to keep things that make money until they stop making money.5.

To make even a modest amount of money you need at least one of the three; to do a more substantial financial gain you need two of three, and to get wealthy you need all three.It starts with education.

Additionally, many SU students from overseas have wealthy parents who sometimes purchase nearby properties for their children and friends to live in while they attend SU and then retain them.As far as neighborhoods go, @Alexis Bliss is spot on in recommending someone with deep local knowledge and connections. 

To become wealthy , one has to take (Calculated!)

I find very few truly wealthy individuals would deal at the street level.. 

.$200 or $400 per month cash-flow per unit is fine, but the real wealth is built buying odd or otherwise strong but unfinancable assets at discounts and repurposing or renovating smartly into something special.Will I now buy an A class single fam at a 20% discount that only breaks even or loses a couple hun a month with 10% down?

What the folks above said, but adding that the likely reason there was no conviction is because she has wealthy parents that pay for a very good attorney when she does wrong. 

How to deal with unexpected situations ... etc. 2% versus 3% versus 4% is not going to make you wealthy at this stage.
