Commission not counting as income for loan?

Hey what’s up everyone, I’ve been an AE for about five years consistently making around 200K selling saas the past 3 or so years. I’ve had lots of friends in sales purchase homes over the past few years. My wife and I are in the market the next couple years but my father-in-law, who is a mortgage broker, told me that you need to have commission from the same exact company for two years in order for it to qualify as income (unless I am selling to the same exact type of company for 2 years, at different orgs). I know there’s a rule on 2 year averages, but the same company thing or selling to same exact type of company threw me off. I think he’s wrong tbh despite being a loan officer for 40 years. (He thinks that since I sold logistics saas and now martech saas, it’s ‘different industry’). As if I went from selling insurance to appliances..

I was shocked by this since how many AEs buy homes, as well as the fact that the average tenure for AEs is usually around a year and a half (or less) per company.

Given that most of us have 50-50, variable splits, have any of you come across the same situation when qualifying for a loan?

real life situation:

Let’s just say you made 200K, 2 years straight but at two different companies.
