Looking at a house with rental mobiles too Rental info needed (Mount Pleasant: buying, income)

[Free2move]

Hi We are looking at a nice house with rental mobiles in Mount Pleasant... These homes are rented out by the week but they have been there for a couple of years. They are charged $100.00 a week & there water & sewer is included ( about 90.00 for each unit ) plus the owner now ( & has been for as long as its been there ) pays the 1st 100.00 of there elect. bill each month.
What is the going rental rates and what included these days?
There is a 2 that we would pull out and replace But the is very little income coming out of this the way it is now -
Is it fair that 1 person pays the 100.00 week & a family of 5 pay 100.00 a week? I would think, with the water and sewer included the more people the more they should pay? & less for 1 person.
So If there is any one who now rents out & has some info I would be glad to hear from you. or if you know of a website i can go to for the Laws & rules of renting out. I would be investing everything I have and need to do it right.
Thanks a bunch to all

And if you don't buy it point me to it. We are considering buying something where we can put my father andmy mother in law near us but not under the same roof. I would be intersted in giving that a peek.
