Landlord Blues: Renting out the house from hell

Okie (1st January, 11.16):
May your new year be blissfull, blessed, beautiful and benevolent.A prosperous new year to you and yours by the grace and mercies of God. Happy new year. 
I presume that was a general one sent out to all his pals. Not sure about the ‘benevolent’ bit; was he trying to get us to let him off his rent? I said to  Adrian: 
'Bugger the texts wishing our new year be blissful, blessed, beautiful and benevolent [got to like the alliteration]; just pay the rent on time.' 
‘Yes,’  Adrian said, ‘to me that is blissful.’ 
He then paid late in January, so I had to remind him. He seemed to think each time this happened that it was the first time. 
We were refurbishing the house, for the umpteenth time, and in the process put in new carpets in Jason and Peter’s old bedrooms and the passage and stairs. We then received the following:
Okie (25th January, 12.41):
Good morning  Adrian. Thanks I can see carpets are being fitted as promised. I think my room deserves a new carpet too. I am happy to move everything out and have them fit a new carpet.
 Adrian:(25th January, 13.23):
We can do a deal. U clean and tidy the kitchen before Sunday and make sure it is clean for the viewings and I will sort it.
Okie (25th January, 13.24):
Hahaha! Deal.
Okie (27th January, 7.38):
Cleaned the kitchen last night.
 Adrian (27th January, 9.42):
Great. Have u bagged up everything that isn’t yours, cleaned the cupboards and doors, cooking rings and floor?
Okie (27th January, 9.44):
Yup, done. I’ll be back from church by 3pm.  But you can take a quick look around cleaned d floors last nyt. 
Okie (30th January, 17.37):
Good evening  Adrian. As discussed when will you send the men to fix the carpet in my room? I’m going to be free and available this weekend.
We were keen to let the two rooms as quickly as possible, whilst also being very careful this time - for a long time, we'd been missing half the rent we should have been getting for the house.
'I could do without Okie pestering about a new bloody carpet,' Adrian said. 
Each time before a viewing,  Adrian had to text Okie to tell him to clean up. As he was the only person living there, any mess was his, so he wasn’t asking him to clean up after anybody else.
Okie (15.56, 15th February 2013):
I got a text from Rebecca asking that I pay in the rent – the reason why there is a delay is due to the fact that I’m a bit down financially, due to some things I had to sort out in Africa, hence I will send the rent when my office pay day reaches and that’s 21st. So that’s why. I apologise for this inconvenience.
'The cheek of living there,' I was now cursing him on a daily basis. 'He thinks he can use all the electricity etc., demand a new carpet and then not even pay the flipping rent.'
 Adrian (15.59, 15th February):
Thanks for update. If u need to pay late u should inform us rather than us chase u. Please pay on time next month. Thanks.
Okie (16.02, 15th February):
Sorry  Adrian, didn’t inform you as I believed I would source funds elsewhere. I should have told u on those occasions we saw at home. A million Thanks for understanding. Best regards.
 Adrian (15th February, 16.43):        
That’s fine. Take care.
