a better question is why are you so horny for the approval of random internet strangers??
Like you either understand what the issue is here and are pretending not to in order to fish for a reaction; or you don't and your questions along with that knee-jerk reaction of "nuh uh not ALL landlords!!!" are totally genuine... but if you truly don't understand then there are much better ways to gain understanding than inviting random unqualified lemmy users to criticize the intimate details (at least the limited amount of such details that can be shared in a lemmy thread from a single perspective) of your extremely unique situation, and then getting upset and going on about "legions of frothing idiots online" when they do exactly that.
I could ask questions like, "how did that woman's house get sold to you literally right out from under her?", "is it fair that this elderly woman is generously allowed to live in her own basement now because at least she's not homeless?", and "do you think that woman might have had the opportunity to buy her own house, and yourself to buy a separate home from hers, if speculation hadn't driven up housing prices?" but I'm also just a random dumbass on the internet with a total knowledge of jack shit on your specific situation and just enough on property/capital ownership to understand that landlording as a practice and as a system is parasitic and exploitative in nature.
Why are you so horny to paint a brush that all landlords are evil and "eat the rich"?
What I'm horny for is understanding that situations may be complex and idiots willing to espouse a novel are probably the ones that might have the issue lol
Edit - and it wasn't her house ya dillhole but of course that would involve actual willingness to understand the situation. She moved in prior to me buying the house.
Nobody here said all landlords are evil and eat the rich. They said landlording is parasitic and not a job. You're the one that got defensive about your teeny tiny edge case, presumably because you want to identify with the title of landlord without all the baggage, maybe you want to carve out room to be "one of the good ones", then lumped us all in with those other viewpoints. Regardless, whether or not everyone here agrees with those viewpoints and how they apply to your specific situation has very little bearing on how you're gonna continue to live your life or the larger conversation about landlording as a practice so like I'm just trying to find a point here other than rehabbing your self-image.
Also, she was living in it. It was not her property, she probably wouldn't have had to sell it if she was paying the mortgage herself instead of paying rent to a landlord to take a profit from before paying the mortgage, but it was and still is her home.
