So, not defending the land lord here, but, what if his dad built and maintained the buildings for years, but now he's like 65 and doesn't really want/or is able to do the work himself so he pays someone else, he is now a piece of shit land lord? I mean, he probably in that scenario doesn't have a retirement, so the return on his investment (profit after costs) is his retirement. He could sell them, and make a profit, but the next landlord would just up rents so he isn't eating those costs.

If he jacks up rents to retire fat and happy after his maintenance costs then he's kinda a dick but if costs stay the same it shouldn't matter who does what work.

I guess I say all this because I am a landlord of a small complex. I bust ass and do all tge work myself keeping rent lower than anyone else I'm town. We rent to seniors that live on fixed incomes and these people have been our tenants so long they are family. They came to my wedding, they came to our baby shower. I will not price them out of a place to live. But the truth is, I am getting tired. I already work two other jobs and this place needed a lot of work when we bought it so he have remodeled most of them. But I am about done. We have had offers to buy in recent years. A few of them would have made 2 million in profit, but half our tenants would be homeless.

Some of our tenants are widowed elderly women that can't afford or maintain a whole household on their own. They are legitimately there for the maintenance, not just the place to live.
