Does a mobile or modular home have a deed?

Generally:

Homes are not transferred by deed, the real estate to which the home is attached is transferred by deed. A modular home is permanently attached to the real estate and therefore ownership would be acquired and transferred by deed.

Ownership of a mobile home is evidenced by a certificate of title. Once the mobile home is purchased it can be installed on a rented lot on another person's land. When the owner wants to sell, she must sign over the title to the new owner and a new certificate of title is obtained through the DMV in most states. However, state laws vary and the laws in your state should be checked.
