My net experience is that the burden of dealing with said landlord to get something fixed or maintained is roughly similar to fixing it yourself with equal pros and cons on both sides.
Consider a $150 repair for your AC going out in 95F weather, 70% humidity. Landlord can and is allowed to take 2 weeks to fix that. (even with the best of intentions, he might still take 2 weeks) Whereas you can easily call and have it fixed within 5 hours if you owned it. Also, many repair companies will refuse repair if you are a renter unless they receive authorization. Also, consider that you want to upgrade to a smart thermostat, because your mercury-laden thermostat is from the 1980s.
Also worth noting that a home warranty program helps a lot with these things both for my landlord and for myself as a landlord.
Also, seems like some of the conversation implicitly revolves around “renting an apartment” vs “buying a house”. I own 2 apartments and rent a house. I don’t have to maintain the yard for the apartments I own. I do have to maintain the yard for the house that I rent.
