sure the city and state in which the home is located, the park and it's rental fees along with amenities and demand to get into the park are most of what you have going for you. I would definitely drive around the park and see if anything is for sale, how long it's been for sale, and how much it's selling for. Mobile homes themselves don't bring a lot of cash, but the park could bring the value of that home up much higher than the "blue book" listing shows. A great way to get an idea is through the bank. Tell them you are interested in refinancing... If the home has a decent engine you got a nice ride.
