Investment Sales vs SaaS/Industrial/IT/Automotive Sales

Hi everyone,

This question likely comes from a different background then most of the folks here, and I am not certain I'll find the right answer here, but I'd love to the get the input of you incredibly talented folks on the cre sales side. I am getting a finance degree, but my passion and experience is in professional sales. I am finishing up my undergrad and I am fortunate enough to have a number of solid opportunities in front of me. I wasn't really considering CRE, but an interesting role came across my desk with a Boutique CRE firm that specializes in NNN retail properties nationally. Please Note this is not a major HCOL metro (Detroit). OTE means on target earnings:

SaaS Sales - 45-50k Base, 75-80k OTE
Industrial Sales - 50k Base, 60 - 75k OTE
It Consulting Sales - 55k Base, OTE isn't sure
Automotive Manufacturing - 65k Base, 80 - 85k OTE (I have to wait till I finish Undergrad for this one. I am one year out)

or

Commercial Real Estate Investment Sales - Small Salary Initially/100% commission after I get going.

The reason I have considered investment sales is because I am going to be full-force grinding 60 - 80 hours for the next 4 - 8 years, cold calling, prospecting, networking etc (All things that I absolutely love), and I want to get the highest ROI.

Of the 4 first gigs, I am leaning towards SaaS, as I can easily push 150k+ in my 3rd year, 200 - 400k+ is not unrealistic mid career (5-7 Years in).

However, from what I understand, commercial real estate can be much more lucrative, the managing directors at this firm pull 100mm + in gross sales each, which I imagine translate into 1.5 mill + in commission. One of those brokers was doing that 4 years out of college.

However, the uncertainty and extraordinarily long sales cycle of RE somewhat scares me. I don't want to burn myself out for the next 2 years and have absolutely nothing to show for it. If I don't perform (unlikely) in other gigs, at least I will still had a nice base salary to work with. I am very young though, and now is the time to take risks.

Thoughts?
