Preserving Access to Manufactured Housing Act of 2013 - Amends the Dodd-Frank Wall Street Reform and Consumer Protection Act to revise the exclusion from the meaning of "mortgage originator" of any employee of a retailer of manufactured homes who does not for compensation or gain take residential mortgage loan applications, for compensation or gain offer or negotiate terms of a residential mortgage loan, or advise a consumer on loan terms (including rates, fees, and other costs).

Excludes from the meaning of "mortgage originator," instead, any retailer of manufactured or modular homes or its employees unless the retailer or its employees receive compensation or gain for engaging in certain activities in excess of any compensation or gain received in a comparable cash transaction.

Amends the Truth in Lending Act to revise the definition of "high cost mortgage."
