I am starting to wonder if we don't get these requests because we self-manage. Maybe it is easier to speak to the property manager who then has to do the dirty work of asking the landlord for these petty things.
Maybe because they would have to ask us directly, they have a second think before asking.
We just don't get these requests.
I would not install anything because the tenant "wanted" it. If their request was reasonable and would be an improvement for our IP, we would certainly consider it, and we generally upgrade as and when required, eg, adding some window security, or install air-con or dishwasher, because as our rents rise, we feel that these things become "expected" or at least, the house will rent quickly or for better weekly rent over a house without air-con or dishwasher.
The only time I can think of that we got a tenant request was when some long term tenants asked if we would allow them to install a window air-con on the condition that they would make good when they left. We decided to install a split system because it was a good thing for us to have for the next tenants.
So, maybe it is the anonymity of being able to ask someone who has no financial interest in the house, and make out the problem is bigger than it is that makes them bold enough to ask for "extras" after signing a lease "as is".
