Same situation here. For my case. My tenant sometimes can come home quite late....then slept till quite late too. My air con is non-invertor type. Hence for eg me and hubby slept at 11pm - 630am daily. but my tenant on air con from 12am till 12pm or even later i would not know as i already gone to work. So just imagine the usuage....basically is almost daily 12hrs minimum air con usage!! Somemore she had lab top, reading lamp & a 24hrs power on "radio"alarm clock in her room.
She use my 8.5kgs washer once a week and i use 2 times a week. I used to give her 2 days a week too..but i realise she use my washer olso when she just have 5-6pcs of clothings!! So eventually i feel that a day is sufficient for her.
Although my tenant seldom at home...but i realise my utilities bills had raise our usual 80 (before our tenant) to 170 for the past few months and now whopping $230 this month!!! Its only 3 person in the house including my tenant!!! I get a real SHOCK!!!
I do not know if it is because of the recent 10% hike in the bills or mis-used of electricity somewhere?i do not intend to raise her rental yet..i wanna monitor first..but tot of sharing with her the hike of my bills and if she can help us by exercise more saving in some ways too? Is it nice to do it this way??In dilema!!
