     PART I

     ITEM 1.  Business.

     The trust fund (the "Trust") created pursuant to a Pooling and Servicing
     Agreement dated as of January 1, 2001 (the "Pooling and Servicing
     Agreement") among Structured Asset Mortgage Investments Inc., a Delaware
     corporation, as seller (the "Seller"), Washington Mutual Bank
     ("Washington Mutual"), in its capacity as originator (the "Originator")
     and in its capacity as master servicer (the "Master Servicer"), and
     Bankers Trust Company of California, N.A., a national banking
     association, as trustee, (the "Trustee").

     The Washington Mutual Mortgage Loan Trust Mortgage Pass-Through
     Certificates, Series 2001-1 (the "Certificates") will consist of the
     classes of Certificates offered under the Prospectus Supplement to the
     Prospectus dated November 24, 2000 (the "Offered Certificates") in
     addition to the other classes of Certificates (the "Other Certificates"),
     which are not being offered.

     The Certificates will evidence in the aggregate the entire beneficial
     ownership interest in the Trust.  The Trust will consist of (i) the
     Mortgage Loans; (ii) such assets as from time to time are identified as
     deposited in respect of the Mortgage Loans in the accounts established
     for the collection of payments on the Mortgage Loans serviced by the
     Master Servicer and in the Certificate Account and belonging to the
     Trust; (iii) property acquired by foreclosure of such Mortgage Loans or
     by deed in lieu of foreclosure; (iv) any applicable insurance policies;
     and (v) all proceeds of the foregoing.

     The Certificates will evidence in the aggregate the entire beneficial
     ownership interest in the Trust.  The Trust will consist of (I) the
     Mortgage Loans (other than the Retained Interest); (ii) such assets as
     from time to time are identified as deposited in respect of the Mortgage
     Loans in the accounts established for the collection of payments on the
     Mortgage Loans serviced by the Master Servicer and in the Certificate
     Account and belonging to the Trust; (iii) property acquired by
     foreclosure of such Mortgage Loans or by deed in lieu of foreclosure;
     (iv) and applicable insurance policies; and (v) all proceeds of the
     foregoing.

     Information with respect to the business of the Trust would not be
     meaningful because the only "business" of the Trust is the collection
     on the Mortgage Loans and distribution of payments on the Certificates to
     Certificateholders. This information is accurately summarized in the
     Monthly Reports to Certificateholders, which are filed on Form 8-K.
     There is no additional relevant information to report in response to Item
     101 of Regulation S-K.

     ITEM 2.  Properties.

     The Depositor owns no property.  The Structured Asset  Mortgage
     Investments Inc. Washington Mutual Loan Trust Mortgage Pass-Through
     Certificates, Series 2001-1, in the aggregate, represent the beneficial
     ownership in a Trust consisting primarily of the Mortgage Loans.  The
     Trust will acquire title to real estate only upon default of the
     mortgagors under the Mortgage Loan.  Therefore, this item is inapplicable.

     ITEM 3.  Legal Proceedings.


     None.


     ITEM 4.  Submission of Matters to a Vote of Security Holders.

     No matters were submitted to a vote of Certificateholders during the
     fiscal year covered by this report.


     PART II

     ITEM 5.  Market for Registrant's Common Equity and Related Stockholder
     Matters.

     The Structured Asset  Mortgage Investments Inc. Washington Mutual Loan
     Trust Mortgage Pass-Through Certificates, Series 2001-1 represents, in the
     aggregate, the beneficial ownership in a trust fund consisting of the
     Mortgage Certificates.  The Certificates are owned by Certificateholders
     as trust beneficiaries.  Strictly speaking, the Registrant has no "common
     equity," but for purposes of this Item only, the Registrant's Structured
     Asset  Mortgage Investments Inc. Washington Mutual Loan Trust Mortgage
     Pass-Through Certificates, Series 2001-1 are treated as "common equity."

     (a)  Market Information.  There is no established public trading market
     for Registrant's Certificates.  Registrant believes the Certificates are
     traded primarily in intra-dealer markets and non-centralized inter-dealer
     markets.

     (b)  Holders.  The number of registered holders of all classes of
     Certificates on December 31, 2001 was:  5.

     (c)  Dividends.  Not applicable.  The information regarding dividends
     required by sub-paragraph (c) of Item 201 of Regulation S-K is
     inapplicable because the Trust does not pay dividends.  However,
     information as to distribution to Certificateholders is provided in the
     Monthly Reports to Certificateholders for each month of the fiscal year
     in which a distribution to Certificateholders was made.

     ITEM 6.  Selected Financial Data.

     Not Applicable.  Because of the limited activities of the Trust, the
     Selected Financial Data required by Item 301 of Regulation S-K does not
     add relevant information to that provided by the Monthly Reports to
     Certificateholders, which are filed on a monthly basis on Form 8-K.

     ITEM 7.  Management's Discussion and Analysis of Financial Condition and
     Results of Operations.

     Not Applicable.  The information required by Item 303 of Regulation S-K
     is inapplicable because the Trust does not have management per se, but
     rather the Trust has a Trustee who causes the preparation of the Monthly
     Reports to Certificateholders.  The information provided by the Monthly
     Reports to Certificateholders, which are filed on a monthly basis on
     Form 8-K, do not provide the relevant financial information regarding the
     financial status of the Trust.

     ITEM 8.  Financial Statements and Supplementary Data.


     Monthly Remittance Statement to the Certificateholders dated as of
     February 26, 2001, and filed with the Securities and Exchange Commission

     Annual Statement of Compliance by the Master Servicer will be
     subsequently filed on Form 10-K/A after March 31, 2002.

     Independent Accountant's Report on Servicer's will be subsequently filed
     on Form 10-K/A after March 31, 2002.

     ITEM 9.  Changes in and Disagreements with Accountants on Accounting and
     Financial Disclosure.

     None.


     PART III

     ITEM 10.  Directors and Executive Officers of Registrant.

     Not Applicable.  The Trust does not have officers or directors.
     Therefore, the information required by items 401 and 405 of Regulation
     S-K are inapplicable.

     ITEM 11.  Executive Compensation.

     Not Applicable.  The Trust does not have officers or directors to whom
     compensation needs to be paid.  Therefore, the information required by
     item 402 of regulation S-K is inapplicable.

     ITEM 12.  Security Ownership of Certain Beneficial Owners and Management.

     (a)  Security ownership of certain beneficial owners.  Under the Pooling
     and Servicing Agreement governing the Trust, the holders of the
     Certificates generally do not have the right to vote and are prohibited
     from taking part in management of the Trust.  For purposes of this Item
     and Item 13 only, however, the Certificateholders are treated as "voting
     security" holders.

     As of December 31, 2001, the following are the only persons known to the
     Registrant to be the beneficial owners of more than 5% of any class of

     (b)  Security ownership of management.  Not Applicable.  The Trust does
     not have any officers or directors.  Therefore, the information required
     by Item 403 of Regulation S-K is inapplicable.

     possess, directly or indirectly, the power to direct or cause the
     direction of the management and policies of the Trust, other than in
     respect to certain required consents regarding any amendments to the
     Pooling and Servicing Agreement, the information requested with respect to
     item 403 of Regulation S-K is inapplicable.

     ITEM 13.  Certain Relationships and Related Transactions.

     (a)  Transactions with management and others.  Registrant knows of no
     transaction or series of transactions during the fiscal year ended
     December 31, 2001, or any currently proposed transaction or series of
     transactions, in an amount exceeding $60,000 involving the Registrant in
     which the Certificateholders identified in Item 12(a) had or will have a
     direct or indirect material interest.  There are no persons of the types
     described in Item 404(a)(1),(2) and (4) of Regulation S-K, however, the

     (b)  Certain business relationships.  None.


     (c)  Indebtedness of management. Not Applicable.  The Trust does not have
