Do you have to respond to that needy tenant that calls everyday?!

[Troy F.]

I have a conversion four plex in Wisconsin which has some great long term tenants.  I am finding it difficult to respond to a particular tenants needs every day.  They call daily with questions like; do you think the other tenant's dog will hurt mine? I am missing a package..do you think someone stole it?  The heat is too high.  The heat isn't high enough.  I have a hard time balancing between responding to this tenants needs and just being a sounding board.  What is my responsibility to answer these calls?  I've started letting them go to voicemail but they never leave a voicemail so I feel compelled to answer.  I do feel responsible for the heat.  The 4 unit is heated by one furnace, controlled by one thermostat in one apartment.  I don't want them to freeze of course but I also don't feel it's right to text the other tenant daily to ask them to turn it up a notch or down a notch.

Any suggestions on how to handle this problem that only seems to be getting more consistent?

Thanks!
