How to convince a math/physics degree can translate to commercial analysis?

I am a licensed broker, relatively new in the industry with 6 months of experience. I currently work at a Brokerage that specializes in residential leasing and multi-family sales with units 8. I'm committed to finding work as a commercial real estate analyst - I'm searching for something more mathematically complex with a higher analytical learning curve.

As background, I was a math/physics major with a very high GPA and years of independent physics research in undergrad. After school I did a few years of full stack software development at a boutique financial derivatives firm (from implementing models in software, networking market data, to working on UI tools for traders) before pivoting to 4 years of self employment in music and audio. 

I've started working in real estate about 6 months ago and realized that it has the potential to blend the right amount of social and analytical skills that I want out of a career. An underwriting position at a large firm would be the ideal starting position for me, and I have been networking heavily for a while now, but I haven't heard back from a single application. I am wondering if there is a certain course I should take; master's degree, Argus training, some sort of underwriting certificate-  that would help my resume rise above others. I have self studied underwriting at this point and have a decent grasp on the fundamentals of financial investment.
