I didn't invoke a "mon and pop situation renting out a spare unit" idea, that's your own that you're projecting on my comment.
I did say that they are a small landlord, and I stand by it given that a large landlord is several orders of magnitude larger than them. If in your world that's only a label you want to give someone renting out a single spare unit, then so be it. I disagree.
> mon and pop situation renting out a spare unit
> small landlord
Those are effectively synonymous to me. The line in the sand that definitively makes you not a small time landlord is if you earn enough from rental income after expenses to make as much as the average job's income.
If you disagree I will need you to define what "small time landlord" means to you then so we can figure out the gap in our understanding.
