FEMA populated the Housing Portal immediately after Sandy with hundreds of fictitious rental units. The resources of REALTORS across the country are publicly recognized as being accurate and updated every 15 minutes. My personal experience showed property owners were frustrated because they did not know how or where the callers got their number to call and ask to rent. FEMA's standard was to put information online based upon recent newspaper ads up to 3 years old and allow that information to stay active for 21 days unless an email was received to report the unit was unavailable.
Sorry to say that I have been consumed with Sandy issues for almost 3 months at work, but off the radar of the decision makers as being a small, local staff-person.
