notes to a landlady

[captainfisto.livejournal.com]

My current landlady is Russian and I am moving out next month. I want to leave her a note saying that something along the lines of "thank you, but it is time for me to go." How does this sound to a native Russian speaker? Is it too much? Is it awkward? Is переводить the right verb?

Благодарю вас за время, в вашем прекрасном доме, но теперь моя пора переводить.

Thanks for your help.

What does this sentence mean "Обещаний нет и быть не может"? 

It is taken from the tekst "Сантиметры дыханья" by МакSим.
