Officials at The Holocaust Documentation and Education Center, at home in downtown Hollywood since 2007, want to strike a deal that could have the center operate virtually mortgage free.The 30-year nonprofit center’s permanent home, an art deco building at 2031 Harrison St., was purchased in August 2004 from the Hollywood Community Redevelopment Agency for $1.2 million payable over 15 years. In the past, it had been housed at Florida International University and other Miami-Dade locations.Now, after spending $3.5 million in renovations and repairs and facing $17,000 in mortgage payments per month, the center’s board is asking the CRA to retake ownership of the building then lease it back to the center for $1 a year for 99 years.
