Would it make more sense to focus on SFH because there are more of those potential deals  in my area or be patient and wait on a multi family that fits my criteria when available?

Lastly, be patient.

One of the former managers even stole tenants' money order rent payments, rented to friends and family who didn’t meet the minimum requirements, and managed some owners' properties on the side without authorization.I’ve tried to be patient, waiting for them to get things back on track, but the situation has only worsened.

They may make unreasonable complaints about me and then I find myself patiently explaining the terms of the lease again and why things are the way they are.  

Be patient and save more for a year, 2.

This way, you stay disciplined about your future while making space for present enjoyment.You can also adopt a mindset shift by focusing on experiences over material things, as experiences tend to offer lasting satisfaction without derailing your financial goals.

By being patient and disciplined, you've been able to scale up to properties you once thought were out of reach.Your version of house hacking, combined with strategically using your profits and capital to reinvest, shows how incremental steps can lead to bigger opportunities over time.

Most importantly be patient, you are 17 :)

If you find something, go hard money and then spend the next few months re-leveraging the existing debt.You can have your cake and eat it too, just be patient my friend. 

I'll echo what @Anthony Vicino said: If you're not willing to be patient and put in the hard work, you aren't going to be successful no matter which coaching program you're in.
