It will no doubt make you more focused, more hungry and more methodical when dealing with real estate in the future.  

I am looking for my next real estate investments.I have been doing fix-n-flips for the past 5 years or so, but that market seems to have dried up.

By approaching from the "objective analysis" rather than "who is the good and bad guy", you are really educating a basic investor.Capital call is a myth/method created by the lender as a temporary measure by the lender to avoid foreclosure.Nonetheless, these capital call is created because the lender itself is willing to take a such very high risk investment that should not happen in the first place.A DSCR loan of 0.85 80% LTV should not happen in the first place.

What were the methods you used. 

I JV'd with another person on the 7th to sell it. 2 LTR purchases were the BRRRR method, which were my last two BRRRRs.

This is something i've been trying to define myself as I don't want to rely on the first come first serve method. 

I am especially interested in learning to master the BRRRR method, but also ready and willing to use traditional methods to build my portfolio.

I can attest to these methods first hand.

@Zach Chandler if you are going the self-manage route, which I highly recommend because it’s simple, as @Gerald Pitts mentions, use the Short Term Shop’s ‘Enemy Method’.

By keeping borrowers informed at every stage, this method helps avoid misconceptions.
