You face a number of difficulties in the situation. First, you should submit your background and credit check information to see if the problem resolves itself. Second, if the mobile home park does not wish to rent to you, you face the prospect of moving the trailer, as my colleague stated. This is an expensive proposal, as I believe mobile home moving costs a minimum of $5000. Third, you may face the prospect of not being able to move your mobile home. In Colorado, a licensed mobile home mover is not allowed to move a mobile home of more than 25 years. Nearly all moving of mobile homes require a licensed mobile home mover. It is possible that your trailer may not require a license mover, but if it does, the mobile home must meet certain criteria for moving. If the mobile home is more than 25 years old based upon its registration, you will own a mobile home at a location where you cannot rent, and the home will not be eligible for moving. As for a prohibition on improvements to your trailer, this requires some clarification. Does the mobile home park owner mean that you would be unable to paint the interior or change a floor covering of the interior? Does the mobile home park owner mean that you must hire their approved contractors to make improvements? Or does the mobile home park owner mean that they wish to have their mobile homes fall into disrepair by prohibiting any and all improvements to them? I wish you well in the resolution of this matter, but you must proceed with manager of the park to determine what courses of action are available.
