Stepping out of your area of expertise for a personal investment (specifically developmental)
I’ve been a CRE broker focused in industrial properties for 4.5 years now. The only career I’ve had post college. 

I’ve been saving money since I was a researcher for whatever I felt was the right investment since day one, and I’m confident I’ve found it. 

Being honest with myself however, I feel most my knowledge of this industry leaves me uneducated on the vacant lot I’d be developing into a duplex. 

My question relevant to this subreddit is, did you ever step out of your field training for an investment in real estate? Did you find yourself regretting/wishing you had stuck to your roots?

Purely anecdotal advice is more than fine, I just wanted to mull over opinions.
