I currently work full time as an air traffic controller and looking for opportunities to generate active and passive income through rental properties, flips, wholesales, etc.

Remember, the only reason you buy this class of house is to generate monthly cash flow and provide lower income families a decent to live.Rule #6:  Hire a Seasoned Property ManagerI think this one speaks for itself.  

I really need help installing systems and finding the gaps in my business.For wholesalers doing it it full-time or those generating consistent weekly to monthly deals, what's your advice on taking you business to the next level.

If you ever get the chance to produce for them you might have a customer for life. 

The higher the contractor charges, the more you get the job done quickly.On another note, I am also picky on my customers, just because someone has a $100k rehab project, it doesn't mean I want to take it because there is money to be made, we had to look for workability, standard, expected quality, contracting knowledge of a client, we are screening you as you are screening us. 

I've got enough houses to generate $20k gross per month, I work 60+ per week and I live overseas without a property manager. 

However, they're sometimes weary of an investor just looking to hang their license for the discount and will ask upfront that you commit a certain amount of hours a week (that's up to your local hiring team).As an associate agent you wouldn't be taking the transactions across the finish line yourself, including your own, but you WOULD save more money as Redfin gives a big discount to their associate agents for their personal transactions above and beyond normal customers get, but there is a limit (~2 a year I believe).I LOVE LOVE LOVE Redfin, but from my experience it's not a place to just hang a license - they'll be wanting to hire and train someone who be at least part-time. 

If you don't know how to do this, then find someone who does and let them work the file.Right now, the only value you add is as quasi-lead generator.
