Hey Robert, my wife and I are local and she is a real estate broker.

Local real estate broker How did you finance this deal?

Having worked with 1,000's of investors to Broker the properties I sell in my local market, and having worked with dozens of Property Managers, Turnkey Providers, Agents, Property Management Software Companies, Lenders, Inspectors and various other investment real estate vendors to market their products and services on my show, the one thing that stood out to be was the CEO Zach's obsession with the biz.In real estate we've get a lot turnover, a lot of flameout.

Good point - At least in FL, since I am licensed I can pay to the other agent's broker legally.We pay the same regardless if it is an RE agent or not, i.e. we pay that same rate to friends, family, current clients, vendors, etc.

BiggerPockets has a decent system for finding a real estate broker in any given area.

Vetting tenants on my own to avoid paying broker fees is the way to go

You'll want to source these deals off market from brokers and wholesalers.I have no links with wholesalers or any brokers in off market world.
