None of this includes any repairs the home may have needed at the time of purchase. Nor does it include any upgrades. Nor does it include any unexpected repairs that may not be covered by insurance (there are many). Nor does it include any of the dozen or so minor repairs you either have to do yourself or get a handy man for.
I'm not going to symp for the landlords but maintaining property is brutally expensive. I know because I bought a 40 year old house. Since I bought a home I've become very convinced that there are a ton of landlords losing their ass out there. Some have been saved by the ridiculous property valuations we've seen lately. But that is not the norm. Houses typically increase in value at a pace with inflation.
Personally, I would only ever rent housing I had specced myself because the design choices and material choices have a huge impact on the cost of maintenance.
