So I don't have a business model in which to provide you, but my two cents:1) Identify what your main bottle neck is in the process.

You can shower at the gym, you can drink bottled water but you might want to consider water and toilets if they stay. you don't want clogs.

I put all of their names on 1 lease, though give them the option to pay their portion separately, always take 1.5 months security because college students love banging counter tops, throwing beer bottles, and tossing each other into walls after 2 shots of gin.Students typically get their refund check end Sept-ish, I give them an option to pay Fall semester Sept-Dec (4 months) and spring semester Jan- May (5 Months)  up front, with no discount. 

We lived in New Jersey for a short while, same story, we get water from local wells and my wife only drinks bottled water.

The area is famous for mineral springs: a lot of the bottled spring water sold throughout the country comes from there.Loutraki is built next to the sea in the shadow of the base of a mountain.

As in your house isn't going to sell like a bottle of water in the Mojave.Note the post by the realtor who is a first hand account of the slow down...."
