This is a question I get asked at least once a day during the summer months.  This year, it is mainly Americans asking the question.

In short, 6-room houses are around the 6000-7000 NIS mark, 5 room duplexes/apartments around 5000-5500 NIS, 4 room apartments around 4000-4500 NIS. The most expensive rental I know of was a furnished, Tzarfati cottage on Yosef at $2500 per month but that was a bit of an exception.
