Gotta get you a good PMS to manage effectively.

We are working with a designer and project manager out of state to setup a STR for a property we just bought. 

If you have a reserve of $6,000 for one property, your annual cash flow could still be hit hard by a bad tenant, or the combination of a bad tenant and a failed furnace.I'm curious how you manage to spend 4-6 hours per day on real estate.

The bigger issue is you need the ability to manage the entire process. 

You plan an active role so it should not be as pronounced as a hands off ADU addition.  

I don't count flipping houses part time or owning a couple rentals, but working as a property manager or asset manager for an operator.  

True , GC is like a teacher to subcon , but after years of experience , it is the GC that’s hands on , practical and having leverage.my GC guy would kill me if I hired his subcon and giving him 40 dollar per hour , for example , lol.GC and subcon is like manager and employee in tech company lol ….

Can't wait to see you grow.If you're planning to invest out-of-state, I recommend reading “Long-Distance Real Estate Investing: How to Buy, Rehab, and Manage Out-of-State Rental Properties” - I found it to be very helpful when I got started investing 2.5 years ago.

House hacking will also give you some personal "property management" experience.

Current interest rates are going to make it difficult to reinvest into real estate and not come out of pocket more than $1000 annually, per your current situation.I am also assuming you are paying a property manager with your current figures.
