2 bedroom house in Crediton

Hi, we are looking to move from Devon to Cornwall for my job. We have 2 dogs, 2 cats, 2 humans. As expected, the search is proving very difficult. We can buy a mobile home, but can't find anywhere to site it. So, we can afford rent up to 750 per month, or, rent land and buy a mobile home. Any advice or somewhere to live would be appreciated. Thanks
