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.  

In previous posts people have used both financial analysis/projections, and point to point critique to try to explain this, but it hasn’t resonated with the true believers.

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.

I was also planning to work for a property managing firm to learn the ropes of the state and local codes while continuing to invest.
