Buying or Selling a Manufactured Home

The Seller Must:

  1. Be sure that all property taxes are paid on the manufactured home.Note: When a title is submitted to the Division of Motor Vehicles for recording a new owner’s name, by law, it must be accompanied by a certificate of taxes paid or an authentication form issued by the county treasurer. This certificate shows whether any property taxes are due on the manufactured home.
  2. Provide the buyer with a certificate of title to aid the transfer of title.
  3. Provide a listing of the household furnishings including the sales price.

The Buyer Must:

Effective July 1, 2006, Secure and Verifiable Identification is required for all transactions. The identification must be provided by the owner of record or with a power of attorney presented by the agent. The agent must have a secure and verifiable identification to complete the transaction.

Please contact the Clerk and Recorder’s office if you need a list of accepted identification, 303-413-7710

  1. Apply for a new title from the clerk and recorder’s office within
    • 45 days of the sale of a new manufactured home or
    • 30 days of the sale of a used manufactured home.

    Failure to file an application for a new title can result in a fine of up to $1,000.

  2. Have a certificate of taxes paid.
  3. File the application for title in the same county where the manufactured home is located.Example: If the manufactured home will be located in Boulder County, you must apply for title within Boulder County.
  4. Notify the county assessor (in county where manufactured home is located) that you are the new owner.

A bill of sale does not transfer ownership. All legal rights are transferred only when the new title is recorded.
