month-to-month lease risks?

[Gary Smith]

My lease is up in 2 days. I want to move, but don't have a place yet. And I don't know if I can get a place.

I want to do a month-to-month lease at $50 more, but someone told me the rent could be raised higher. But rents aren't being raised these days.
And if I went back to a 6 month lease, it would be at the price of the month-to-month lease. Is that true?
