Jaycee, I'm not trying to be argumentative. I know what you are saying, but what I'm trying to say is that if I had rented a property that did not have air-conditioning, I would rather sort it out for myself (if that was what I wanted) than ring the Landlord.
If I wanted to live in a home that had air-conditioning, I simply would not even look at one that didn't have it. Period! If I made an error in judgement, then it would be me that had to suck it up and live with it and that might mean buying a cheap portable to see me through until I moved.
I just don't understand tenants that lease a property then ask the Landlord to improve it. Mind you, I don't have any problem telling them that I won't do it either.
Some people are different to you... I get it.... Hardly a surprising fact (?)
For me it comes down to accepting this sort of thing is part of what you have to deal with in resi property investing, the reality of dealing with human beings (which, before we forget... we are too, although I know we're all superior ones of course ).....
