One thing you should consider is there are some great programs in Boise that will let you buy a home like that on their own lot for cheaper than paying the interest on these properties plus space rent in a park. They are tough to resell if they are not on their own lot which may be why this one has been online for 180+ days.
The person they have noted as the "agent" isn't even a member of the MLS locally so I am not sure what to say other than maybe driving by and knocking on the door?
Best of luck!
