what is more common lease or month to month?

[Gon Eisenberg]

Hello,

As an investor who didn't grew up in the states. I'm interested to know what is more common in the us month to month or lease. 

Is there anyone who can figure out an assessment for that? maybe even just a guts feeling about it.

Is there a good resource I can get a precise answer to that?

Thanks in advance,

Gon
