Carefree Resort Mobile Home, Bullhead City

we were going to buy a mobile at the park from the owner not the park. we have poor credit and we told the onsite manager this. she said it was fust a formality and we paid 50.00 dollars for the credit check. we were turned down. we had offered to put up a deposit but the manager said this was not necessary being we were paying cash to the owner. if you own the mobile and are paying 325.00 a month rent to the park and willing to put up 500.00 deposit to the park, where are you going with a mobile that cant be moved? i think the management co. should stay in california.
