This is how it is in the UK and I'm wondering if it's the same in the US, since that's what I expected. From what I've read it seems like in the US (I've looked at Texas and California) a reason has to be given and the valid reasons I've seen listed are non-payment of rent, renovations that will take over a certain number of months, use of the property by the landlord or selling. I've not seen which states have evictions with literally no necessity to state a reason.
