Dear Sirs/Madams:


Re:   Realmark Property Investors Limited Partnership IV
      (Commission File #: 0-14386)


We have read Item 4 of Form 8-K/A - Amendment No. 2, of Realmark Property
Investors Limited Partnership IV (the "Company") dated April 17, 2000 and have
the following comments:

1.    We agree with the statements made in the first paragraph. With respect to
      our "resignation letter", our letter was the standard AICPA SEC Practice
      Section Notification Letter confirming the cessation of the client-auditor
      relationship, a copy of which was provided to the Office of the Chief
      Accountant of the Securities and Exchange Commission.

2.    We agree  with the  statements  made in the  second,  third,  fourth and
      fifth paragraphs.

3.    We agree with the statements made in the sixth paragraph, however, we
      believe that the statements made regarding the "Draft Letter" require
      clarification. The document referred to as the "Draft Letter" is a draft
      of our report dated April 30, 1999 that communicates certain matters
      considered to be material weaknesses in the Company's internal controls as
      well as certain other observations regarding internal controls and other
      matters relating to the Company.

4.    We agree  with the  statements  made in the  seventh,  eight  and  ninth
      paragraphs.

5.    We have no basis for agreeing or disagreeing  with the  statements  made
      in the tenth and eleventh paragraphs.

6.    We agree with the statements made in the twelfth paragraph.

Very truly yours,

Deloitte & Touche LLP
