there is a large gap between "can live off of"(my words) and "a lot less than my salary as a senior SDE"(your words). If you're making more than the median household income which based on the fed numbers is ~84k/yr[1] you've crossed the line past small time landlord. You may be making less than that, but I am going to be surprised if you are with ~55 tenants.
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.
> 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.
According to [1] (Doorloop, 2026), Greystar manages 823,581 units as the largest landlord. The 10th largest landlord is WinnCompanies with 120,855 units. These are "very large" to me. If we make a generous curve then a large landlord has 10% of those units, so somewhere in the 10,000 unit range, a medium landlord 10% of that or 1,000 units, a small landlord 10% of that or 100 units, and a very small landlord has the last interval of 1-10 units. Hence, 55 units is somewhere between very small and small.

You can disagree with that definition but don’t pretend like I didn’t give one and then explain to me what my beliefs should be.
