    paragraph_quote: 'B8-2-02, Special-Purpose Security Instruments (12/10/2025) Introduction
      This topic contains general information on special-purpose security instruments,
      including: General Information Consolidated New York Mortgages Puerto Rico Direct
      Mortgage Instruments Security Instruments for Manufactured Home Mortgages Uniform
      Appraisal Dataset (UAD) 3.6 Policy General Information Fannie Mae sometimes
      allows special-purpose alternative documents to be used in lieu of (or in addition
      to) the typical security instruments. These documents can be found on Fannie
      Mae''s Legal Documents website. Authorized changes that must or may be made
      to those documents are set out in the instructions that accompany each document.
      These instruments must be supported by the appropriate mortgage riders, rider
      addenda, mortgage assignments, and, if applicable, other product-speciﬁc documentation
      (see B8-4, Riders and Addenda, and B8-6, Mortgage Assignments). Published May
      6, 2026 892 Consolidated New York Mortgages The statutory provisions of New
      York permit reﬁnance mortgages (and sometimes purchase money mortgages) to be
      documented by a consolidation, extension, and modiﬁcation agreement (CEMA) that
      consolidates into one document the terms of prior notes and mortgages related
      to the security property and, if new funds are advanced, the terms of a new
      note and mortgage. In such instances, the consolidation must be documented on
      Fannie Mae’s standard Consolidation, Extension and Modiﬁcation Agreement (Form
      3172), along with any accompanying exhibits Fannie Mae may specify. If new funds
      are advanced, Fannie Mae’s standard security instrument must be used to document
      the new mortgage that is being consolidated with the prior mortgages. Puerto
      Rico Direct Mortgage Instruments The statutory provisions of Puerto Rico permit
      a mortgage transaction to be documented by a single instrument that combines
      the terms of a note and mortgage. This is referred to as a “direct” mortgage.
      Fannie Mae does not publish standard legal documents for direct mortgages; therefore,
      lenders must develop (or acquire) appropriate documentation for these mortgages
      consistent with the applicable Puerto Rico statutes. By delivering a direct
      mortgage to Fannie Mae, the lender must make the nonstandard document warranties.
      (See A2-2-02, Delivery Information and Delivery-Option Speciﬁc Representations
      and Warranties.) Security Instruments for Manufactured Home Mortgages Fannie
      Mae prefers lenders to use the standard Fannie Mae uniform instruments for manufactured
      home loans sold to it. Loan documents are not acceptable if they: state that
      the home is personal property or contain other words to that eﬀect; state that
      the parties do not intend to attach the home to a permanent foundation system
      on the land, or contain statements inconsistent with that intention; unless
      required by law, provide that rights of holders in due course are waived, or
      with other words provide that an assignee note holder may be held liable for
      claims the borrower may have against other parties; or include consumer ﬁnance
      paper (which combines the note and security instrument in a single document)
      or a retail installment sales contract. The following list provides the requirements
      for the security instrument used for a manufactured home loan. The property
      description section of the security instrument must include a comprehensive
      description of the manufactured home and the land. The description must include
      the serial or VIN number (or the serial number or VIN for each unit if the home
      is multi-width), make, model, size, and any other information that may be required
      by applicable law to deﬁnitively identify the home. The serial number is located
      on the HUD Data Plate located on the interior of the home, usually near the
      electrical box. In addition, the serial number is generally cold stamped on
      the frame front cross member of each transportable section. Some jurisdictions
      may not allow any information in the property description section of the security
      instrument other than what is customary for other real property transactions.
      If this is the case, then an addendum may be Published May 6, 2026 893 used,
      which must be attached to the security instrument and included in the loan ﬁle.
      The security instrument must state that the manufactured home is an improvement
      to the land and an immovable ﬁxture, or must include similar language as may
      be required by applicable law to assure, to the greatest extent possible, that
      the manufactured home is treated as real property under applicable state law.
      If applicable law provides speciﬁc obligatory wording, such wording must be
      used. The borrower(s) and any lender with a personal property security interest
      in the manufactured home must sign an Aﬃdavit of Aﬃxture that acknowledges their
      intent for the manufactured home to be permanently part of the real property
      that secures the mortgage free of any personal property security interest. It
      must also contain any speciﬁc language that may be required by applicable law.
      The Aﬃdavit must be signed by both the lender and the borrower(s), preferably
      recorded, and must be retained in the loan ﬁle. Failure to include the Aﬃdavit
      of Aﬃxture in the loan ﬁle may result in the loan being ineligible for delivery
      to Fannie Mae. If state law requires a Uniform Commercial Code (UCC) ﬁling in
      order to perfect a security interest in a manufactured home, the lender must
      make such ﬁling in any and all appropriate locations. Uniform Appraisal Dataset
