                                       3

           This Amendment No. 20 amends the Schedule 13D filed by Odyssey
Partners, L.P. ("Odyssey"), with respect to the beneficial ownership of common
stock, $1.00 par value ("Common Stock") of Avatar Holdings Inc. (the "Issuer").

Item 2.    Identity and Background.

           This statement is filed on behalf of Odyssey and Jack Nash. Odyssey
and Jack Nash are referred to herein collectively as the "Reporting Persons,"
and may be deemed to constitute the members of a "group".

           Leon Levy, a general partner of Odyssey and the Chairman of the Board
of the Issuer died on April 6, 2003. As a result, he is no longer a general
partner of Odyssey and therefore, is no longer deemed to beneficially own the
Common Stock owned by Odyssey. The Estate of Leon Levy retains an interest in
Odyssey but does not have any voting or dispositive power with respect to the
Common Stock beneficially owned by Odyssey.

           Odyssey has five general partners (individually a "General Partner"
and collectively, the "General Partners"): Jack Nash, Joshua Nash, Stephen
Berger, Brian Wruble and Nash Family Partnership, L.P., a New York limited
partnership.

           Odyssey's principal executive office is located at 280 Park Avenue,
New York, NY 10017. The business address of each General Partner is 280 Park
Avenue, New York, NY 10017.

           Jack Nash also serves as the Chairman of the Board of Directors of
the Issuer.

Item 4.    Purpose of Transaction.

           The Reporting Persons have acquired the securities of the Issuer for
investment purposes. The Reporting Persons may acquire additional securities of
the Issuer or dispose of securities of the Issuer at any time and from time to
time in the open market, in privately negotiated transactions with third parties
or otherwise. Although the foregoing represents the range of activities
presently contemplated by the Reporting Persons with respect to the Issuer, it
should be noted that the possible activities of the Reporting Persons are
subject to change at any time.

           Jack Nash is a general partner of Odyssey and Chairman of the
Issuer's Board of Directors. Accordingly, the Reporting Persons will be in a
position to influence the management, operations and activities of the Issuer.

           Except as set forth above, the Reporting Persons have no present
plans or intentions which relate to or would result in any of the actions
described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5.    Interest in Securities of the Issuer.

           (a) The responses of the Reporting Persons to Rows (11) through (13)
of the cover page of this Amendment No. 20 are incorporated herein by reference.
As of the close of business on August 1, 2003, Odyssey beneficially owned
2,107,763 shares of Common Stock, representing approximately 24.1% of the


                                       4

outstanding shares of Common Stock (the outstanding shares of Common Stock,
8,733,885, being based on the number of shares outstanding as of July 31, 2003,
as reported as reported by the Issuer in its press release issued on August 1,
2003).

           As of the close of business on August 1, 2003, Jack Nash beneficially
owned 2,108,205 shares of Common Stock (composed of (i) 442 shares of Common
Stock owned by him and (ii) 2,107,763 shares of Common Stock beneficially owned
by Odyssey for which Mr. Nash may be deemed to be the beneficial owner as
described in Item 5(b) hereof), representing approximately 24.1% of the
outstanding shares of Common Stock (the outstanding shares of Common Stock,
8,733,885, being based on the number of shares outstanding as of July 31, 2003,
as reported as reported by the Issuer in its press release issued on August 1,
2003).

           To the best knowledge of Odyssey, none of the General Partners (other
than Jack Nash) own any shares of Common Stock, other than indirectly, as a
general partner of Odyssey.

           (b) The responses of each of the Reporting Persons to (i) Rows (7)
through (10) of the cover page of this Amendment No. 20 and (ii) Item 5(a)
hereof are incorporated herein by reference. All General Partners (excluding the
Nash Family Partnership, L.P.) share voting and dispositive power over the
shares of Common Stock. Each General Partner of Odyssey (including Jack Nash)
may be deemed to be the beneficial owner of the shares of Common Stock
beneficially owned by Odyssey for purposes of Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), because each shares
voting and investment power over such shares with the other General Partners of
Odyssey. Pursuant to Rule 13d-4 under the Exchange Act, each General Partner
(including Jack Nash) hereby expressly disclaims beneficial ownership of such
shares to the extent such beneficial ownership exceeds such General Partner's
fractional interest therein as a general partner of Odyssey, which fractional
interest is not presently determinable.

           (c) - (e) Not applicable.

Item 6.    Contracts, Arrangements, Understandings or Relationships With
           Respect to Securities of the Issuer.

           Jack Nash is a general partner of Odyssey and the Chairman of the
Board of Directors of the Issuer. An agreement among the Reporting Persons with
respect to the filing of this statement is attached hereto as Exhibit 1.

Item 7.    Materials to be Filed as Exhibits.

    Exhibit 1         Joint Filing Agreement between Jack Nash and Odyssey
                      Partners, L.P., dated August 4, 2003.

correct.
