How much extra should you charge for a month to month lease?

[Craig Janet]

I have a mobile home that I'm renovating. Due to a large industrial project in the area, there is a need for short term housing for construction workers. I'm trying to decide whether I want to do a month to month furnished with all bills paid vs a typical long term lease. How much extra should I charge. Below are the details.

Regular long term lease $850, electricity $250, water $50, internet $75. How much extra should I add for the increased turnover and hassle of a month to month.
