If you have no agreement signed in writing, you're hooped. There's no terms agreed upon by either party and you can be kicked out at any time. You're really not considered to be anything really.. Why would you not get a lease signed? yikes
Maybe i'm missing something.. I've been dealing with a jerk of a landlord who pre-maturely tried to kick us out 8 months before our lease ran out, fortunately we have a fixed term lease in place that both parties signed and we've been here ever since, with some annoyances here and there, pointless showings... ect. (Who's going to buy a house with a tennant in there for 5 months??)
I've had people come look at our place in the evening while i've been watching a Flames game, with a beer in my hand. It's quite humerous
