You hit the nail right on the head.

As a renter, you are stuck between a rock and a hard place.

Contacting your landlord to get something resolved is a nightmare. Majority of the the time they will refuse to cover it and refuse to send someone out.

Majority of the time they will also not let someone come fix it, without approval, because you aren't not allowed to make modifications to someones property.

We had a fan which died upstairs in a bedroom. The downstairs had an aircon although it was a living room. We requested the fan get replaced multiple times, 13 months late (two different rent increases later) the fan was still not replaced. A third price increase without the fan being replaced and we moved.
