I am not sure its possible to make enough money to make this a good living with AMC work. Your expenses, needs and wants in your 30s are different than in your 40's. My advice is to go commercial as well or find a new career path before you are too old to pivot. I just do not think this is a viable full-time career for most. Sure it can happen, but typically not. There are other careers where one can work from home as a 1099 outside of appraisal. Hell, many corporate jobs are fully remote now. You are not master of your domain, but its close. And with benefits. I have to imagine in your area you need well into six figures to live, save, and play. That's a ton of AMC work.
I started in my early 30's and now in my 40s have no real wealth to show for it like my counterparts in corporate. I never made enough money appraising to adequately save for retirement and buy a small cabin on top of supporting my family. And I worked many 50+ hour weeks, weekends included. Sure I had a few great years, but always followed by down years. Only now am I almost compete with my transition out of appraisal. Part of my problem is that I was never really excited or ambitious enough to want to work on complex valuations. (So you need to be the opposite of me), I also hated the boots on the ground marketing work. It was exhausting to me just to get a 1004 here and there. Even the property tax lawyer in my town was constantly trying to low-ball me. It was a constant struggle completing tasks that did not directly result in revenue. After years of it, the struggle just wears you out man. then you get jaded and bitter like I am about this job.
Not sure your degree will help. I have BS, MBA, (had the SRA gave it up this year), numerous certs and AMCs could care less.
I just hate to see someone waste their prime earning years chasing a buck just to get by not really building wealth. Especially when one might be able to snag a corporate analyst (financial or real estate) job working from home.
