Yeah, and if someone made me that offer on my current ($2k/month) apartment, I would turn it down despite it being a 50% discount because I don't want the uncertainty of having to move in a year. This is not a problem if both parties know up front. The only way it becomes a problem is if I think I'm renting an apartment for $1k/month and then a year later my landlord says "Oh, actually your rent was $5000/month but you had the $4000/month move-in discount for the first year, your rent is now $5250/month".
