The limits depend on the rules of each round. That being said, so long as you incur the hardware costs and legal fees during your 6 months in the program it should be reimbursed. However consult with your rounds rules first, and when in doubt ask your account executive.
As for how easy, I'd say it depends on what you are used to. Finding a place, now that there are two full rounds in Chile, is getting harder. You'll have to look on a bunch of sites (I recommend homechile.cl) Sometimes you can get lucky doing door to door to apartments. In June the first participants in the second round will be starting to leave chile so it might be worth asking the community then.
